    - by Sunny
    Hi, I am creating a search using listview. when user enter a word in search, I am generating a listview with the results. Now, there will be tags in each listview row. When, user clicks the tag, again a search happens using the value in the tag. There may be any number of tags for each listview row. I have to generate linkbuttons for these tags. Could anyone please guide me on how to create dynamic linkbuttons and access those values for further search. You can have a look at delicious.com. I need a similar functionality. Thanks in advance.

  • Windows media player control with .NET

    - by brovar
    What I want to do is to read media files (pics and videos) from a directory and display them one by one using the WMP control (AxWMPLib.AxWindowsMediaPlayer). In its older version it was enough to check the file's duration to distinguish images from videos, the new one randomly shows movies' duration properly or as zero. Does anyone know any other way of finding out what file is being proceeded withouth checking its extension (as a file can have an extension of .abc or so)? I'll be very grateful for any help. (Sorry for my lousy English.)

  • Tree View / File View Control for C#

    - by Jason
    I have been looking for a C# tree control for displaying a file system that has the following capabilities: Select a starting directory. I don't always want to start at a "default" top directory level. The ability to grab an event when the user double clicks on a file in the tree. I want to handle opening the file within my application. I have been looking at this C# File Browser. Unfortunately, I have not been able to figure out how to do meet my second need. (If anybody can clear that up for me, I would like that even better.) Thanks for any help.

  • OnDataBinding firing before OnLoad of a CustomGridViewControl in a UserControl?

    - by OutOFTouch
    Hi, I have a CustomGridViewControl that is on a UserControl, the UserControl is loaded outside of the Page_Init when a treeview in the page is clicked that changes the view, than on subsequent postbacks the UserControl is loaded in Page_Init. The custom gridview is bound to a dataview that is dynamically retrieved. Problem is that the OnDataBinding of the CustomGridView is firing before the OnLoad of the CustomGridView, which is causing me to not be able to get embedded resource urls. Any suggestions? Thanks!

  • Why Can't I store XML in ASP.NET ListBox Value?

    - by mcass20
    Hello, Why does this work: ListItem item = new ListItem(); string value = lstAvailExtPropsToFilter.SelectedItem.Text +" = "+ txtExtPropToFilter.Text; string text = lstAvailExtPropsToFilter.SelectedItem.Text + " = " + txtExtPropToFilter.Text; item.Text = text; item.Value = value; lstExtPropsToFilter.Items.Add(item); But not this: ListItem item = new ListItem(); string value = string.Format("<key>{0}</key><value>{1}</value>", lstAvailExtPropsToFilter.SelectedItem.Text, txtExtPropToFilter.Text); string text = lstAvailExtPropsToFilter.SelectedItem.Text + " = " + txtExtPropToFilter.Text; item.Text = text; item.Value = value; lstExtPropsToFilter.Items.Add(item);

  • Can I pass events like key strokes to another control in Silverlight?

    - by herzmeister der welten
    Can I pass events like key strokes to another control in Silverlight? Imagine I'm in a custom control that contains a Textbox and a Treeview. I'm listening to a Key event for the TextBox. When the user pushes the Arrow Up or Arrow Down key, I want the Treeview to behave as if it's itself who received that event, i.e. it should move the current selection up or down. The user shouldn't lose focus on the TextBox though so that they can continue typing. Is this possible? I don't want to set the selection manually on the Treeview because it has no easy MoveSelectionUp() or MoveSelectionDown() method, so I would have to duplicate that functionality which is not so trivial especially when the tree is databound and loads nodes on demand.

  • Help setting focus on the parent

    - by serhio
    I have a simple situation (.NET2): a texbox1 on a UserControl1(or Form1). I want to unfocus(leave) the texbox when I click on the usercontrol/form(focus the usercontrol/form instead): I do the following on the UC/form: Protected Overrides Sub OnMouseClick _ (ByVal e As System.Windows.Forms.MouseEventArgs) MyBase.OnMouseClick(e) Me.Focus() End Sub Why does it not work on the child textbox, but works very well on the non-child one(focus on textBox2 then click on the panel removes the focus from the textBox2)?

  • What method can I override in GridViewHeaderRowPresenter to prevent it from drawing some columns?

    - by Carlo
    The thing is that I created a custom column that inherits from GridViewColumn, and I added a Visibility dependency property to it. Now I want to create a custom GridViewHeaderRowPresenter, that does not draw the columns when their visibility is hidden or collapsed, but other than the OnRender() method, I can't think of anything else. Thanks. Btw, the reason I'm doing this is because removing or adding columns doesn't work like we would expect it (some specs for our app) and I believe what I'm trying to do here would work if pulled out correctly.

  • WFP Textblock in Listbox not clipping properly

    - by Tobias Funke
    Her's what I want: A listbox whose items consist of a stackpanel with two textblocks. The textblocks need to support wrapping, the listbox should not expand, and there should be no horizontal scrollbar. Here's the code I have so far. Copy and paste it into XamlPad and you'll see what I'm talking about. <ListBox Height="300" Width="300" x:Name="tvShows"> <ListBox.Items> <ListBoxItem> <StackPanel> <TextBlock Width="{Binding ElementName=tvShows, Path=ActualWidth}" TextWrapping="Wrap">Lost is an American live-action television series. It follows the lives of plane crash survivors on a mysterious tropical island.</TextBlock> <TextBlock Width="{Binding ElementName=tvShows, Path=ActualWidth}" TextWrapping="Wrap">Lost is an American live-action television series. It follows the lives of plane crash survivors on a mysterious tropical island.</TextBlock> </StackPanel> </ListBoxItem> <ListBoxItem> <StackPanel> <TextBlock Width="{Binding ElementName=tvShows, Path=ActualWidth}" TextWrapping="Wrap">Lost is an American live-action television series. It follows the lives of plane crash survivors on a mysterious tropical island.</TextBlock> <TextBlock Width="{Binding ElementName=tvShows, Path=ActualWidth}" TextWrapping="Wrap">Lost is an American live-action television series. It follows the lives of plane crash survivors on a mysterious tropical island.</TextBlock> </StackPanel> </ListBoxItem> </ListBox.Items> </ListBox> This seems to be doing the job of keeping the textblocks from growing, but there's one problem. The textblocks seem to be slightly larger than the listbox, causing the horizontal scrollbar to appear. This is strange because their widths are bound to the lisbox's ActualWidth. Also, if you add a few more items to the listbox (just cut and paste in XamlPad) causing the vertical scrollbar to appear, the width of the textblocks do not resize to the vertical scrollbar. How do I keep the textblocks inside the listbox, with or without the vertical scrollbar?

  • WPF EDitable ComboBox

    - by Amittai Shapira
    Hi! I want to create editable combo box with the following properties: 1. Bind the text property to my data model. 2. The data model may override the changes in the GUI, even in Selection changed. E.g. I can choose from 1, 2, 3 I choose 2, but some component down under changes it to 3. 3. Update the data model on the following events: 1. Selection Changed 2. Lose focus 3. Enter pressed (should behave the same as lost focus). I've been able to create such control, but it's pretty ugly (using many hacks) and I hoped there's a simpler way… Thanks in advance

  • Labelsize appears bigger in VB.Net

    - by Ikke
    I'm trying to stack a few lists on top of each other. But the label.size.height appears to be bigger then the label itself. When i set the borderstyle to fixedsingle, i see the border around the text. But the height is bigger, so there comes a space between one label and the next. I have tried to set margin and padding to 0 without result. Exemple: label.size.height return 23, when the height actually is something around 15. Does someone knows how i get the right size? Edit: When i explicitly set the height of the lable, the problem is solved. Is this some problem with autosize?

  • Input string was not in correct format.

    - by jawahar-sync
    Hi Experts, I had a Ribbon like custom control. I created an application using this control. These applications work fine until I change the system number format. They crashes if I change the system number format like below: Current Format = English (United State) Decimal symbol = ',' Digit group symbol = '.' When I run applications, they throw an exception "Input string not in Correct format". . Some other applications specify the Exception's message = "Input string '0,2,0,2' was not a correct format", so I think in Wpf ES's xaml files, we may declare some properties i.e Padding, Margin like "0,2,0,2" = that will cause errors with the system number format above. I have note that this error only occurs in Windows Vista, it does not occurs on Windows XP. I do not know why? I have also look at this link, But it not helps for Vista. http://support.microsoft.com/kb/968227/en-us

  • How do I show and position an Image initialized in the codebehind on my page?

    - by Andreas Strandfelt
    Hello. I have created a simple method to check if an image has been approved and finally returns it as an control. But how do i call and show it on the page? I've tried something like this in the aspx-file: <% SendImage("DKBygMiniLogo.gif", "True"); %> Here is the simple method: protected Image SendImage(object Image, object Approved) { bool approved = Convert.ToBoolean(Approved); Image img = new Image(); if (approved) { img.ImageUrl = "~/images/Ads/" + Image.ToString(); img.Visible = true; } else { img.ImageUrl = "~/images/Ads/" + Image.ToString(); img.Visible = false; } return img; } How do I actually show the image?

  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by enchilada
    My question is based on another question. Instead of repeating a bunch of stuff, I hope it's okay that I refer you to that other question instead: http://stackoverflow.com/questions/1203698/show-nssegmentedcontrol-menu-when-segment-clicked-despite-having-set-action/ My question is: How would the code within [self showGearMenu] look like, i.e. how would one actually use the popUpContextMenu:withEvent:forView method to accomplish what the poster of the other question wants? I ask because it seems that the question was resolved for the poster, but he never shared with us how he actually popped up the menu :)

  • Why won't my control accept keyboard input?

    - by Mason Wheeler
    I've built a custom control that I'm trying to send input to. It will accept mouse input and report MouseDown, MouseMove and MouseUp correctly, but for whatever reason, it won't accept keyboard input. When I click on it, it doesn't receive focus, and any keys I press get interpreted by whatever control had the focus already. This is probably something really simple. The first place I thought to look was in the ControlStyle property, but the only thing I can see in the helpfile about keyboard input is csNoStdEvents, which disables it, and my control doesn't have that. So what do I need to do to make it so my control can receive input focus?

  • Exposing some live data on a website - New to ASP.NET, need guidelines

    - by Carlos
    I have a large .NET based system running within the company intranet, which allows winforms users to see some live calculated numbers and a custom winforms control drawn live (but not real-time). The Forms users can also affect the operation of the system. I would like to just show the live numbers on a website, along with the custom control. Nothing needs to come back from the web user, as the web app is meant to be just for monitoring. All the numbers can be calculated at the server. It's been a long time since I touched ASP.NET, and I need to know how to proceed. What are the steps in building and deploying such a website? Any caveats I need to look out for?

  • WPF4 DatePicker - adding time

    Now that there is an official MS DatePicker in WPF4, I was wondering if there was a way to let it edit the Time part of a DateTime as well. I can't see anything, but it seems rather obvious to have missed out?
