• What data should I (can I) gather to prove a .net bug in third party software?

  - by gef05

  Our users are using a third-party system and every so often - a user might go all day without this happening, other days they may see it two or three times in seven hours - a red x will appear on screen rather than a button, field, or control. This is a .net system. Looking online I can see that this is a .net error. Problem is, our devs didn't write it, and the vendor wants proof that the problem resides with their system, not our PCs. What can we do to gather information on such an issue that would allow us to make our case to the vendor and get them to create a fix? I'm thinking of data to gather - anything from OS, memory. .net version installed etc. But I'd also like to know about error logging - if it's possible to log errors that occur in third-party systems.

• WPF ToggleButton changing image depending on state

  - by mack369

  I would like to use ToggleButton in following way: There are 5 different images and each of them should be displayed depending on current state: button disabled button enabled, unchecked button enabled, unchecked, pointed by mouse cursor button enabled, checked button enabled, checked, pointed by mouse cursor I've found a simple example with two images on http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/28c36bd2-2ef7-4232-9976-2a0967140e32 , but how to change the image depending on "checked" property? The second question: how can I avoid creating different styles for each button in my application? I'm using about 20 different buttons and each of them has different set of icons. So far I'm using only one icon, below my code. Is it possible to have common code (style and template) and to define the source of images in section where I want to create button (like in section 3 of my code)? <ControlTemplate x:Key="ToggleButtonTemplate" TargetType="{x:Type ToggleButton}"> <Grid> <Border x:Name="ContentBorder" CornerRadius="4" BorderBrush="Transparent" BorderThickness="1" Background="{DynamicResource ButtonOff}"> <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsChecked" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonDisabled}"/> <Setter Property="Foreground" Value="{DynamicResource BorderDisabled}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> <Style x:Key="ToggleButtonStyle" TargetType="{x:Type ToggleButton}"> <Setter Property="Width" Value="64" /> <Setter Property="Height" Value="64" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Template" Value="{DynamicResource ToggleButtonTemplate}" /> </Style> <ToggleButton IsChecked="{Binding Path=IsLectorModeEnabled}" Command="{Binding CmdLector}" Style="{DynamicResource ToggleButtonStyle}"> <Image Source="{DynamicResource LectorImage}" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="None" /> </ToggleButton>

• data validation on wpf passwordbox:type password, re-type password

  - by black sensei

  Hello Experts !! I've built a wpf windows application in with there is a registration form. Using IDataErrorInfo i could successfully bind the field to a class property and with the help of styles display meaningful information about the error to users.About the submit button i use the MultiDataTrigger with conditions (Based on a post here on stackoverflow).All went well. Now i need to do the same for the passwordbox and apparently it's not as straight forward.I found on wpftutorial an article and gave it a try but for some reason it wasn't working. i've tried another one from functionalfun. And in this Functionalfun case the properties(databind,databound) are not recognized as dependencyproperty even after i've changed their name as suggested somewhere in the comments plus i don't have an idea whether it will work for a windows application, since it's designed for web. to give you an idea here is some code on textboxes <Window.Resources> <data:General x:Key="recharge" /> <Style x:Key="validButton" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}" > <Setter Property="IsEnabled" Value="False"/> <Style.Triggers> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding ElementName=txtRecharge, Path=(Validation.HasError)}" Value="false" /> </MultiDataTrigger.Conditions> <Setter Property="IsEnabled" Value="True" /> </MultiDataTrigger> </Style.Triggers> </Style> <Style x:Key="txtboxerrors" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <DockPanel LastChildFill="True"> <TextBlock DockPanel.Dock="Bottom" FontSize="8" FontWeight="ExtraBold" Foreground="red" Padding="5 0 0 0" Text="{Binding ElementName=showerror, Path=AdornedElement.(Validation.Errors)[0].ErrorContent}"></TextBlock> <Border BorderBrush="Red" BorderThickness="2"> <AdornedElementPlaceholder Name="showerror" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> </Window.Resources> <TextBox Margin="12,69,12,70" Name="txtRecharge" Style="{StaticResource txtboxerrors}"> <TextBox.Text> <Binding Path="Field" Source="{StaticResource recharge}" ValidatesOnDataErrors="True" UpdateSourceTrigger="PropertyChanged"> <Binding.ValidationRules> <ExceptionValidationRule /> </Binding.ValidationRules> </Binding> </TextBox.Text> </TextBox> <Button Height="23" Margin="98,0,0,12" Name="btnRecharge" VerticalAlignment="Bottom" Click="btnRecharge_Click" HorizontalAlignment="Left" Width="75" Style="{StaticResource validButton}">Recharge</Button> some C# : class General : IDataErrorInfo { private string _field; public string this[string columnName] { get { string result = null; if(columnName == "Field") { if(Util.NullOrEmtpyCheck(this._field)) { result = "Field cannot be Empty"; } } return result; } } public string Error { get { return null; } } public string Field { get { return _field; } set { _field = value; } } } So what are suggestion you guys have for me? I mean how would you go about this? how do you do this since the databinding first purpose here is not to load data onto the fields they are just (for now) for data validation. thanks for reading this.

• WPF ListBoxItem double-click?

  - by David Veeneman

  The WPF ListBox doesn't have a DoubleClick event, at least not as far as I can tell. Is there a workaround for this issue that would let me double-click on an item to have an event handler do something with it? Thanks for your help.

• Is it possible for a WPF control to have an ActualWidth and ActualHeight if it has never been render

  - by DanM

  I need a Viewport3D for the sole purpose of doing geometric calculations using Petzold.Media3D.ViewportInfo. I do now want to place it in a Window. I'm creating a Viewport3D using the following code: private Viewport3D CreateViewport(MainSettings settings) { var cameraPosition = new Point3D(0, 0, settings.CameraHeight); var cameraLookDirection = new Vector3D(0, 0, -1); var cameraUpDirection = new Vector3D(0, 1, 0); var camera = new PerspectiveCamera { Position = cameraPosition, LookDirection = cameraLookDirection, UpDirection = cameraUpDirection }; var viewport = new Viewport3D { Camera = camera, Width = settings.ViewportWidth, Height = settings.ViewportHeight }; return viewport; } Later, I'm attempting to use this viewport to convert the mouse location to a 3D location using this method: public Point3D? Point2dToPoint3d(Point point) { var range = new LineRange(); var isValid = ViewportInfo.Point2DtoPoint3D(_viewport, point, out range); if (isValid) return range.PointFromZ(0); else return null; } Unfortunately, it's not working. I think the reason is that the ActualWidth and ActualHeight of the viewport and both zero (and these are read-only properties, so I can't set them manually). (I have tested the exact same with an actual rendered Viewport3D, so I know the issue is not with my converter method.) Any idea how I can get WPF to assign the ActualWidth and ActualHeight based on my Width and Height settings? I tried setting the HorizontalAlignment and VerticalAlignment to Left and Top, respectively, and I also messed with the MinWidth and MinHeight, but none of these properties had any effect on the ActualWidth or ActualHeight.

• Custom Checkbox style for WPF

  - by lorddarq

  I would like to skin a wpf default checkbox to something custom. Since it does not really make sense to start off a entirely new control, i'd like to override the Windows Chrome template binding for the Bulletchrome sub component of the checkbox. However I cannot do this like I can with checkboxes for example. tried using something like this to override the default style, but it seems to not compile like this <Style x:Key="cb_BULLETSTYLE" TargetType="{x:Type BulletDecorator}"> <Setter Property="OverridesDefaultStyle" Value="true"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type BulletDecorator}"> <Border x:Name="Chrome" SnapsToDevicePixels="true" BorderBrush="{x:Null}" BorderThickness="0"> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" TargetName="Chrome" Value="#FF4C4C4C"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter>

• What is the differnce between DataTemplate and DataContext in WPF?

  - by Ashish Ashu

  I can set the relationship b/w View Model and view through following DataContext syntax: <UserControl.DataContext> <view_model:MainMenuModel /> </UserControl.DataContext> And I can also set the relationship b/w View Model and view through following DataTemplate syntax: <DataTemplate DataType="{x:Type viewModel:UserViewModel}"> <view:UserView /> </DataTemplate> Please let me know what is the difference between the two ? Is the second XAML does not set the data context of a view ?

• What is the WPF equivilant for the FlowLayoutPanel?

  - by Sargola

  I am working on a WPF application (a one note clone which is called "note your life") where you can dynamically assign Tags to an entry (just as in virtually any web 2.0 app these days). for this I had in my windows forms prototype a FlowLayoutPanel that did the job very well. I want to have the tags float to the next line if there isn't enough space and get a scrollbar if needed. how can this be achieved with WPF? I played around with <StackPanel Orientation="Horizontal" FlowDirection="LeftToRight" ...> but this doesn't move the elements in the next line if needed. Any suggestions?

• AutoCompleteTextView with custom list: how to set up onClick Listeners and getting the selected item

  - by steff

  Hi everyone, I am working on an app which uses tags. Accessing those should be as simple as possible. Working with an AutoCompleteTextView seems appropriate to me. What I want: existing tags should be displayed in a selectable list with a CheckBox on each item's side existing tags should be displayed UPON FOCUS of AutoCompleteTextView (i.e. not after typing a letter) What I've done so far is storing tags in a dedicated sqlite3 table. Tags are queried resulting in a Cursor. The Cursor is passed to a SimpleCursorAdapter which looks like this: Cursor cursor = dbHelper.getAllTags(); startManagingCursor(cursor); String[] columns = new String[] { TagsDB._TAG}; int[] to = new int[] { R.id.tv_tags}; SimpleCursorAdapter cursAdapt = new SimpleCursorAdapter(this, R.layout.tags_row, cursor, columns, to); actv.setAdapter(cursAdapt); As you can see I created *tags_row.xml* which looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingLeft="4dip" android:paddingRight="4dip" android:orientation="horizontal"> <TextView android:id="@+id/tv_tags" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:textColor="#000" android:onClick="actv_item_click" /> <CheckBox android:id="@+id/cb_tags" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="actv_item_checked" /> </LinearLayout> It looks like this: So the results are displayed just as I'd want them to. But the TextView's onClick listener does not respond. And I don't have a clue on how to access the data once an item is (de-)selected. Behaviour of the list should be the following: tapping a CheckBox item should insert/append the corresponding tag into the AutoCompleteTextView (tags will be semicolon-seperated) tapping a TextView item should insert/apped the corresponding tag into the AutoCompleteTextView AND close the list. So please help me out. Thanks in advance, steff

• Examples of WPF forms for usual CRUD scenarios

  - by MicMit

  There are plenty of such examples shown for Silverlight at recent Microsoft conferences ( Creating amazing LOB applications in SL 2,3,4 ... ) . They even invented DataForms starting from Silverlight varsion 3. Basically I need an example of grid view ( maybe with possibility to filter, preferably DataGrid control ) from which we may update/delete selected record(s) or add new ones working against SQL Server database without service layer.

• Binding the position and size of a UserControl inside a Canvas in WPF

  - by John

  Hi. We have dynamically created (i.e. during runtime, via code-behind) UserControls inside a Canvas. We want to bind the position (Canvas.Left and Canvas.Top) and width of those sizable and draggable UserControls to a ObservableCollection<. How would we achieve this if the Usercontrol is contained in a DataTemplate which in turn is used by a ListBox whose DataContext is set to the collection we want to bind to? In other words, how do we bind a control's position and size that doesn't exist in XAML, but in code only (because it's created by clicking and dragging the mouse)? Notice that the collection can be empty or not empty, meaning that the size and position stores in a collection item must be correctly bound to so that the UserControl can be sized and positioned correctly in the Canvas - via DataBinding. Is this possible?

• WPF TextBox.SelectAll () doesn't work

  - by Zoliq

  Hi! I have used the following template in my project: <DataTemplate x:Key="textBoxDataTemplate"> <TextBox Name="textBox" ToolTip="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}" Tag="{Binding}" PreviewKeyDown="cellValueTextBoxKeyDown"> <TextBox.Text> <MultiBinding Converter="{StaticResource intToStringMultiConverter}"> <Binding Path="CellValue" Mode="TwoWay"> <Binding.ValidationRules> <y:MatrixCellValueRule MaxValue="200" /> </Binding.ValidationRules> </Binding> <Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type y:MatrixGrid}}" Path="Tag" Mode="OneWay" /> </MultiBinding> </TextBox.Text> </TextBox> </DataTemplate> I used this template to create an editable matrix for the user. The user is able to navigate from cell to cell within the matrix and I would like to highlight the data in the selected textbox but it doesn't work. I called TextBox.Focus () and TextBox.SelectAll () to achieve the effect but nothing. The Focus () works but the text never gets highlighted. Any help is welcome and appreciated.

  - by black sensei

  Hello Good People!! I bound a datatable to a combobox and defined a dataTemplate in the itemTemplate.i can see desired values in the combobox dropdown list,what i see in the selectedItem is System.Data.DataRowView here are my codes: <ComboBox Margin="128,139,123,0" Name="cmbEmail" Height="23" VerticalAlignment="Top" TabIndex="1" ToolTip="enter the email you signed up with here" IsEditable="True" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}"> <ComboBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Path=username}"/> </StackPanel> </DataTemplate> </ComboBox.ItemTemplate> The code behind is so : if (con != null) { con.Open(); //users table has columns id | username | pass SQLiteCommand cmd = new SQLiteCommand("select * from users", con); SQLiteDataAdapter da = new SQLiteDataAdapter(cmd); userdt = new DataTable("users"); da.Fill(userdt); cmbEmail.DataContext = userdt; } I've been looking for something like SelectedValueTemplate or SelectedItemTemplate to do the same kind of data templating but i found none.

• Acrobat Reader ActiveX in WebBrowser stealing focus [C#]

  - by Maciej

  I'm using webBrowser.Navigate(url) control to display page. I noticed this action steals focus from current control (grid) and than I have problem to focus grid back (tired myGrid.Focus, .Select etc...) This is really annoying behaviour of browser... Does anyone knows how to prevent focus stealing by Browser or (if not) hot to force to focus control back ? EDIT: I've also tried webBrowser.DocumentCompleted event to focus back to grid EDIT 2 Good case to test this is openning PDF files webBrowser.Navigate(@"C:\TEMP\test.pdf") I believe this is ActiveX issue. On first glance it looks that this is not problem with focusing control but loosing entire Form focus... EDIT 3 I tried another approach: Form keyPress event: I thought I can capture form's keyPress and move focus from WebBrowser / AdobeReader ActiveX to my control. But surprisingly event is not fired! Looks Reader taken all control and there is no way to do anything programically until you do mouse click on (at least) form's caption Any advice (s) ?

  - by Ashish Ashu

  I have a user control let say UC1 . This user control have viewmodel UC1_vm. In the usercontrol UC1 I have a canvas in which drawing curve logic is implemented. This drawing curve logic is based on the data points property in the view model ( UC1_vm). The data points property inside the view model change with different condition. The generation of data points is written in the View Model. I want to bind the data points property in the view model to the draw curve logic inside the User control (view). I want whenever the data point property is changed in the view model , the canvas calls the draw curve method. Can I set the set any property of canvas which when changed it calls the on paint logic auto matically? Please suggest me the approach of implementing this scenario!!

• WPF - Only want one expander open at a time in grouped Listbox

  - by Portsmouth

  I have a UserControl with a templated grouped listbox with expanders and only want one expander open at any time. I have browsed through the site but haven't found anything except binding the IsExpanded to IsSelected which isn't quite what I want. I am trying to put some code in the Expanded event that would loop through Expanders and close all the ones that aren't the expander passed in the Expanded event. I can't seem to figure out how to get at them. I've tried ListBox.Items.Groups but didn't see how to get at them and tried ListBox.ItemContainerGenerator.ContainerFromItem (or Index) but nothing came back.

• Side effect of calling ValidatorEnable method: sets focus to control associated with validator

  - by Velika2

  When I called this function to enable a validator from client javascript: `ValidatorEnable(document.getElementById('<%=valPassportOtherText.ClientID%>'), true); //enable` validation control The side effect was that focus was shifted to the txtSpecifyOccupation textbox (the control associated with the Validation control) <asp:TextBox ID="txtSpecifyOccupation" runat="server" AutoCompleteType="Disabled" CssClass="DefaultTextBox DefaultWidth" MaxLength="24" Rows="2"></asp:TextBox> <asp:RequiredFieldValidator ID="valSpecifyOccupation" runat="server" ControlToValidate="txtSpecifyOccupation" ErrorMessage="1.14b Please specify your &lt;b&gt;Occupation&lt;/b&gt;" SetFocusOnError="True">&nbsp;Required</asp:RequiredFieldValidator> Perhaps there is a way to enable the (required) validator without having it simultaneously perform the validation (at least until the user has tabbed off of it?)
