  • Android: Use XML Layout for List Cell rather than Java Code Layout (Widgets)

    - by Stephen Finucane
    Hi, I'm in the process of making a music app and I'm currently working on the library functionality. I'm having some problems, however, in working with a list view (In particular, the cells). I'm trying to move from a simple textview layout in each cell that's created within java to one that uses an XML file for layout (Hence keeping the Java file mostly semantic) This is my original code for the cell layout: public View getView(int position, View convertView, ViewGroup parent) { String id = null; TextView tv = new TextView(mContext.getApplicationContext()); if (convertView == null) { music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE); musiccursor.moveToPosition(position); id = musiccursor.getString(music_column_index); music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DISPLAY_NAME); musiccursor.moveToPosition(position); id += "\n" + musiccursor.getString(music_column_index); music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Albums.ALBUM); musiccursor.moveToPosition(position); id += "\n" + musiccursor.getString(music_column_index); tv.setText(id); } else tv = (TextView) convertView; return tv; } And my new version: public View getView(int position, View convertView, ViewGroup parent) { View cellLayout = findViewById(R.id.albums_list_cell); ImageView album_art = (ImageView) findViewById(R.id.album_cover); TextView album_title = (TextView) findViewById(R.id.album_title); TextView artist_title = (TextView) findViewById(R.id.artist_title); if (convertView == null) { music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Albums.ALBUM); musiccursor.moveToPosition(position); album_title.setText(musiccursor.getString(music_column_index)); //music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DISPLAY_NAME); //musiccursor.moveToPosition(position); music_column_index = musiccursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE); musiccursor.moveToPosition(position); artist_title.setText(musiccursor.getString(music_column_index)); } else{ cellLayout = (TextView) convertView; } return cellLayout; } The initialisation (done in the on create file): musiclist = (ListView) findViewById(R.id.PhoneMusicList); musiclist.setAdapter(new MusicAdapter(this)); musiclist.setOnItemClickListener(musicgridlistener); And the respective XML files: (main) <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView android:id="@+id/PhoneMusicList" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <TextView android:id="@android:id/empty" android:layout_width="wrap_content" android:layout_height="0dip" android:layout_weight="1.0" android:text="@string/no_list_data" /> </LinearLayout> (albums_list_cell) <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/albums_list_cell" android:layout_width="wrap_content" android:layout_height="wrap_content"> <ImageView android:id="@+id/album_cover" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_width="50dip" android:layout_height="50dip" /> <TextView android:id="@+id/album_title" android:layout_toRightOf="@+id/album_cover" android:layout_alignParentTop="true" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/artist_title" android:layout_toRightOf="@+id/album_cover" android:layout_below="@+id/album_title" android:layout_width="wrap_content" android:layout_height="15dip" /> </RelativeLayout> In theory (based on the tiny bit of Android I've done so far) this should work..it doesn't though. Logcat gives me a null pointer exception at line 96 of the faulty code, which is the album_title.setText line. It could be a problem with my casting but Google tells me this is ok :D Thanks for any help and let me know if you need more info!

  • Hide table row based on content of table cell

    - by timkl
    I want to make some jQuery that shows some table rows and hides others based on the content of the first table cell in each row. When I click a list item I want jQuery to check if the first letter of the item matches the first letter in any table cell in my markup, if so the parent table row should be shown and other rows should be hidden. This is my markup: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> <tr> <td>Beta1</td> <td>Some content</td> </tr> <tr> <td>Beta2</td> <td>Some content</td> </tr> <tr> <td>Beta3</td> <td>Some content</td> </tr> <tr> <td>Gamma1</td> <td>Some content</td> </tr> <tr> <td>Gamma2</td> <td>Some content</td> </tr> <tr> <td>Gamma3</td> <td>Some content</td> </tr> </table> So if I press "A" this is what is rendered in the browser: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> </table> I'm really new to jQuery so any hint on how to go about a problem like this would be appreciated :)

  • iPhone keyboard's return key will move curser to next textfield

    - by iAm
    Hello Fellow Koder ••• I have a TableViewController that is using a grouped Style and has two(2) sections. The first section has 4 rows and the second section has 3 rows. I have placed a UILabel and a UITextField in each cell, and have a custom method(textFieldDone:) to handle the cursor movement to the next text field when the return key is press. This works fine and dandy if there is only one section, but I have two :( and yes I need two:) so I started koden' up an answer, but got results that just don't work, I did notice during my debugging that cell Identifier (I use Two) is only showing the one (in the debug consol) and it's the first one only (Generic Cell). - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case AUTO_DETAILS: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 75, 25)]; label.tag = kLabelTag; label.font = [UIFont boldSystemFontOfSize:14]; label.textAlignment = UITextAlignmentRight; [cell.contentView addSubview:label]; [label release]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, 200, 25)]; textField.clearsOnBeginEditing = NO; [textField setDelegate:self]; [textField addTarget:self action:@selector(topTextFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit]; [cell.contentView addSubview:textField]; } NSInteger row = [indexPath row]; UILabel *label = (UILabel *)[cell viewWithTag:kLabelTag]; UITextField *textField = nil; for (UIView *oneView in cell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) textField = (UITextField *)oneView; } label.text = [topCellLabels objectAtIndex:row]; NSNumber *rowAsNum = [[NSNumber alloc] initWithInt:row]; switch (row) { case kMakeRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.make; break; case kModelRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.model; break; case kYearRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.year; break; case kNotesRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.notes; break; default: break; } if (textFieldBeingEdited == textField) { textFieldBeingEdited = nil; } textField.tag = row; [rowAsNum release]; break; } case AUTO_REGISTRATION: { static NSString *AutoEditCellID = @"AutoEditCellID"; cell = [tableView dequeueReusableCellWithIdentifier:AutoEditCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:AutoEditCellID] autorelease]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 75, 25)]; label.tag = kLabelTag; label.font = [UIFont boldSystemFontOfSize:14]; label.textAlignment = UITextAlignmentRight; [cell.contentView addSubview:label]; [label release]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, 200, 25)]; textField.clearsOnBeginEditing = NO; [textField setDelegate:self]; [textField addTarget:self action:@selector(bottomTextFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit]; [cell.contentView addSubview:textField]; } NSInteger row = [indexPath row]; UILabel *label = (UILabel *)[cell viewWithTag:kLabelTag]; UITextField *textField = nil; for (UIView *oneView in cell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) textField = (UITextField *)oneView; } label.text = [bottomCellLabels objectAtIndex:row]; NSNumber *rowAsNum = [[NSNumber alloc] initWithInt:row]; switch (row) { case 0: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.vinNumber; break; case 1: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.policyNumber; break; case 2: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.licensePlate; break; default: break; } if (textFieldBeingEdited == textField) { textFieldBeingEdited = nil; } textField.tag = row; [rowAsNum release]; break; } default: break; } return cell; } Now remember that the first section is working fine and the kode for that method is this: -(IBAction)topTextFieldDone:(id)sender { UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview]; UITableView *table = (UITableView *)[cell superview]; NSIndexPath *textFieldIndexPath = [table indexPathForCell:cell]; NSUInteger row = [textFieldIndexPath row]; row++; if (row > kNumOfEditableRows) row = 0; NSUInteger newIndex[] = {0, row}; NSIndexPath *newPath = [[NSIndexPath alloc] initWithIndexes:newIndex length:2]; UITableViewCell *nextCell = [self.tableView cellForRowAtIndexPath:newPath]; UITextField *nextField = nil; for (UIView *oneView in nextCell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) nextField = (UITextField *)oneView; } [nextField becomeFirstResponder]; } It was my idea to just create a second method (secondSectionTextFieldDone:) like this -(IBAction)bottomTextFieldDone:(id)sender { UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview]; UITableView *table = (UITableView *)[cell superview]; NSIndexPath *textFieldIndexPath = [table indexPathForCell:cell]; NSUInteger row = [textFieldIndexPath row]; row++; if (row > 3) row = 0; NSUInteger newIndex[] = {0, row}; NSIndexPath *newPath = [[NSIndexPath alloc] initWithIndexes:newIndex length:2]; UITableViewCell *nextCell = [self.tableView cellForRowAtIndexPath:newPath]; UITextField *nextField = nil; NSString *string = [NSString stringWithFormat:@"AutoEditCellID"]; for (UIView *oneView in nextCell.contentView.subviews) { NSLog(@"%@", nextCell.reuseIdentifier); /* DEBUG LOG */ if ([oneView isMemberOfClass:[UITextField class]] && (nextCell.reuseIdentifier == string)) nextField = (UITextField *)oneView; } [nextField becomeFirstResponder]; } but the result does not solve the issue. so my question is, how can i get the cursor to jump to the next textfield in the section that it is in, If there is one, and if not, then send a message "resignFirstResponder" so that, the keyboard goes away.

  • HTML table ignoring element-style width

    - by sangil
    HTML table ignoring element-style width I have an HTML table where certain cells have very long text contents. I want to specify a width (in pixels) for these cells using jQuery, but the rendered table just ignores the given width. Is there any way to force the table to respect this width? Thanks! JSFiddle: http://jsfiddle.net/sangil/6hejy/35/ (If you inspect the cell you can see the the computed width is different than the element-style width) HTML: <div id="tblcont" class="tblcont"> <table id="pivot_table"> <tbody> <tr> <th id="h0" >product</th> <th id="h1" >price</th> <th id="h2" >change</th> </tr> <tr> <!-- this is the cell causing trouble --> <td id="c00" >Acer 2400 aaaaaaaaaaaaaaaaaaaaaaaaaa</td> <td id="c01" >3212</td> <td id="c02" >219</td> </tr> <tr> <td id="c10" >Acer</td> <td id="c11" >3821</td> <td id="c12" >206</td> </tr> </tbody> </table> </div> CSS: .tblcont { overflow: hidden; width: 500px; } table { table-layout: fixed; border-collapse: collapse; overflow-x: scroll; border-spacing:0; width: 100%; } th, td { overflow: hidden; text-overflow: ellipsis; word-wrap: break-word; } th { height: 50px; } ?Javascript: $(document).ready(function() { // THIS LINE HAS NO EFFECT! $('#c00').width(30); });

  • Add Hyperlink to Cell in Excel 2007 Using Open XML SDK 2.0

    I can't seem to find any documentation or code samples on how to add a hyperlink to a cell in Excel 2007 using the open xml sdk 2.0. I am using the following code, but is there a step I am missing? WorksheetPart workSheetPart = ExcelUtilities.GetWorkSheetPart(mWorkBookPart, "Program"); workSheetPart.AddHyperlinkRelationship(new Uri("http://www.google.com", UriKind.Absolute), true); workSheetPart.Worksheet.Save(); mWorkBookPart.Workbook.Save(); Then when I try and open the Excel document it says the file is corrupted because the relationship Id for the hyperlink cannot be found. How do you setup or create that relationship Id?

I am doing it like this. CustomCellBackgroundView *custView = [[CustomCellBackgroundView alloc] initWithFrame:CGRectMake(0,0,320,44)]; [cell setBackgroundView:custView]; [custView release]; and doing this gives me transparent cell. I tried and fought with code but could get any results. Please help me out. I am really having no idea how this code will run.

  • autocomplete dropdown in Infragistics ultrawebgrid cell

    Hi, I want to an autocomplete dropdown control in the ultrawebgrid cell in edit mode, so user can type the data and value is filled in automatically if exists, invalid data should not be permitted. is this possible? I don't want to use webcombo, it is too heavy and I don't need a multi-column dropdown. I want a simple dropdownlist, but the ability for the user to type just like Google suggest, but all the values cached on the client, no roundtrip to server on each key stroke. the control should be like the following one http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ComboBox/ComboBox.aspx thanks, RK

  • Silverlight DataGrid set cell IsReadOnly programatically

    - by Brandon Montgomery
    I am binding a data grid to a collection of Task objects. A particular column needs some special rules pertaining to editing: <!--Percent Complete--> <data:DataGridTextColumn Header="%" ElementStyle="{StaticResource RightAlignStyle}" Binding="{Binding PercentComplete, Mode=TwoWay, Converter={StaticResource PercentConverter}}" /> What I want to do is set the IsReadOnly property only for each task's percent complete cell based on a property on the actual Task object. I've tried this: <!--Percent Complete--> <data:DataGridTextColumn Header="%" ElementStyle="{StaticResource RightAlignStyle}" Binding="{Binding PercentComplete, Mode=TwoWay, Converter={StaticResource PercentConverter}}" IsReadOnly={Binding IsNotLocalID} /> but apparently you can't bind to the IsReadOnly property on a data grid column. What is the best way do to do what I am trying to do?

  • Clip UITableView Cell's Separator

    I've been trying to build a view that looks similar to the "stocks" application (surprise). What I would like is to have the scroller bar outside of my rounded table view, shown in the image link below, but clip the cell separators. You can see how they overlap the scroller bar, which is annoying. I can't figure out how Apple put the scroller bar in a spot that looks like it is outside their table. Any ideas?

  • Cocoa: getting a Table View cell to send action messages

    - by underthetable
    I'm really having trouble getting a Cocoa Table View cell to send action messages. At the most basic level, in IB there is an action assigned for the NSTextViewCell object, and after editing and pressing Return nothing happens. So I have an IBOutlet hooked up to the NSTextViewCell, and have been experimenting with NSActionCell messages to it. But the Table View seems to pretty much just ignore them. I've also tried subclassing NSTextViewCell, but the methods I'm seeing all look like they want to pass values to the object from somewhere, not return a value from inside the object to configure its behavior. I'm pretty new to programming and Cocoa -- can someone explain each thing that needs to be overridden and how and where to do it?

How can I do that ? -(void)viewDidLoad { [super viewDidLoad]; self.title = @"Library"; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; cells = [[NSMutableArray alloc] initWithObjects:@"dict1", @"dict2", @"dict3", @"dict4", @"dict5", @"dict6", nil]; dict1 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 01 Feb #2", @"date", @"0.7", @"time", @"1.2MB", @"size", @"200*200", @"pix", nil]; dict2 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Wed, 02 Mar #3", @"date", @"1.2", @"time", @"2.2MB", @"size", @"300*300", @"pix", nil]; dict3 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Tue, 03 Apr #5", @"date", @"1.7", @"time", @"2.5MB", @"size", @"240*240", @"pix", nil]; dict4 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 01 Feb #2", @"date", @"0.7", @"time", @"1.2MB", @"size", @"200*200", @"pix", nil]; dict5 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 10 Nov #5", @"date", @"2.7", @"time", @"4.2MB", @"size", @"200*400", @"pix", nil]; dict6 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Mon, 11 Dec #6", @"date", @"4.7", @"time", @"2.2MB", @"size", @"500*200", @"pix", nil]; //[cells addObject:dict1]; //[cells addObject:dict2]; //[cells addObject:dict3]; //[cells addObject:dict4]; //[cells addObject:dict5]; //[cells addObject:dict6]; } // Customize the number of rows in the table view. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [cells count]; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; //cell.contentView.frame = CGRectMake(0.0f, 0.0f, 320.0f, 80.0f); [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; UIImageView *image1 = [[UIImageView alloc]init]; image1.frame = CGRectMake(0.0f, 0.0f, 80.0f, 80.0f); image1.tag = tag7; UILabel *dateLabel = [[UILabel alloc]init]; dateLabel.frame = CGRectMake(100.0f, 5.0f, 120.0f, 25.0f); dateLabel.font = [UIFont fontWithName:@"Georgia" size:10]; dateLabel.tag = tag1; UILabel *timeLabel = [[UILabel alloc] init]; timeLabel.frame = CGRectMake(100.0f, 30.0f, 40.0f, 25.0f); timeLabel.font = [UIFont fontWithName:@"Georgia" size:10]; timeLabel.tag = tag2; UILabel *sizeLabel = [[UILabel alloc] init]; sizeLabel.frame = CGRectMake(160.0f, 30.0f, 40.0f, 25.0f); sizeLabel.font = [UIFont fontWithName:@"Georgia" size:10]; sizeLabel.tag = tag3; UILabel *pixLabel = [[UILabel alloc] init]; pixLabel.frame = CGRectMake(220.0f, 30.0f, 40.0f, 25.0f); pixLabel.font = [UIFont fontWithName:@"Georgia" size:10]; pixLabel.tag = tag4; UILabel *shareLabel = [[UILabel alloc] init]; shareLabel.frame = CGRectMake(100.0f, 55.0f, 100.0f, 25.0f); shareLabel.font = [UIFont fontWithName:@"Georgia" size:10]; shareLabel.tag = tag5; UILabel *deleteLabel = [[UILabel alloc] init]; deleteLabel.frame = CGRectMake(220.0f, 55.0f, 100.0f, 25.0f); deleteLabel.font = [UIFont fontWithName:@"Georgia" size:10]; deleteLabel.tag = tag6; [cell.contentView addSubview:dateLabel]; [cell.contentView addSubview:timeLabel]; [cell.contentView addSubview:sizeLabel]; [cell.contentView addSubview:pixLabel]; [cell.contentView addSubview:shareLabel]; [cell.contentView addSubview:deleteLabel]; [cell.contentView addSubview:image1]; [dateLabel release]; [timeLabel release]; [sizeLabel release]; [pixLabel release]; [shareLabel release]; [deleteLabel release]; [image1 release]; } // Set up the cell... [(UILabel *)[cell viewWithTag:tag1] setText:[cells objectAtIndex:[dict1 objectForKey: @"date"]]]; [(UILabel *)[cell viewWithTag:tag2] setText:[cells objectAtIndex:[dict1 objectForKey: @"time"]]]; [(UILabel *)[cell viewWithTag:tag3] setText:[cells objectAtIndex:[dict1 objectForKey: @"size"]]]; [(UILabel *)[cell viewWithTag:tag4] setText:[cells objectAtIndex:[dict1 objectForKey: @"pix"]]]; [(UILabel *)[cell viewWithTag:tag5] setText:@"Share"]; [(UILabel *)[cell viewWithTag:tag6] setText:@"Delete"]; cell.imageView.image = [UIImage imageNamed:@"image2.png"]; return cell; } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 80.0f; } I did in above way but it is not working. I know the mistake is at the accessing values. but, I could not get how to do it ? Thank You.

  • 100% height on nested table cell in IE

    - by James Cooper
    I want a nested table to expand to the height of the enclosing cell. This works as expected in Firefox/Chrome/Safari, but not in IE7 or IE8. Please see the example here: http://www.bitmechanic.com/heightDemo.html The DOCTYPE is relevant. While the demo above validates as HTML 4.01 Strict, it does not render properly in IE7. If I remove the DOCTYPE entirely, or set it to HTML 3.2, it renders properly in IE. Any suggestions on how to get this to render in 4.01 (strict or loose)? The actual web site is a bit more complicated -- changing the DOCTYPE will cause all sorts of other problems. We're struggling to understand the (presumed) IE bug here and how to work around it. thanks -- James

  • telerik mvc grid access cell data to enable columns.Command

    - by AZee
    Hi! I can't seem to find a way to reference the value in a column in the grid, in my case it is the StatusId. Based on the cell value in this row, for the StatusId, I need to return a true or false to the method ".Visible(???)". It would be nice to find the answer in the documentation online but I haven't been able to. I find it hard to believe that I would be the first person who ever needed this functionality. I would be most appreciative of any assistance since no one in the telerik forums know. .Columns(columns => { columns.Command(commands => { commands.Edit().ButtonType(ButtonType); commands.Delete().ButtonType(ButtonType); }).Width(90).Visible(???); Thanks!

  • Setting a cell's format using Excel 2007 Interop and C#

    - by CVertex
    I'm using the office 2007 interop assemblies to create some excel spreadsheets. There are plenty of questions on here about getting started and MSDN contains heaps of articles, like this one. The API is funky, and sometimes a bit confusing. When I set a value of a cell, is there a way to set it's format? I'd like to mark particular fields as Date's so my customer can run excel macros on them. Also, numbers would be useful. Thanks!

  • How to copy a formatted cell in Excel to a table cell in Word using .NET?

    - by Harry Nath
    I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

  • Of Datagridviews, databinding, and non validating cell values.

    - by Yanko Hernández Alvarez
    Lets simplify. Lets say I have this class: class T { public string Name { get; set; } public int Age { get; set; } public int height{ get; set; } ... } and I have a DataGridView's DataSource bound to a BindingList <T>, with N columns, each one bound to each property. I need to: Allow the user to enter non validating ages, heights, etc (for instance "aaa") Color the cells with non validating values (red background) Retain the non validating values displayed until the form is closed (I don't want to lose the values entered until the form is closed, so the user has the option to correct the bad cells anytime he wants BEFORE closing the form) Keep the last correct values entered for each cell with non validating values entered. When the form is closed, ditch the non validating values and keep the last correct values entered. Is there any easy way to do this?
