Pasting

I have a shape from one Diagram control and I paste it into a second Diagram control, the paste works fine, but there is no guarantee that the shape will be pasted into the visible area of the screen. Is it possible to address this in some manner? It would be nice to inspect the shape before it is pasted; I can witness the paste via CommandExecuted but the actually shape I am pasting is not present.

ListBox Template - Layout Doesn't Work

Good morning,

I'm having trouble with the RadListBox Template. For some reason if I insert a grid into a listbox template its formatting is not preserved.

Here's my code:

Template:

<DataTemplate x:Key="AutoCompleteListBoxTemplate">

    <Grid Width="{Binding ElementName=radListBox, Path=Width}">

        <Grid.ColumnDefinitions>

            <ColumnDefinition />

            <ColumnDefinition />

        </Grid.ColumnDefinitions>

        <TextBlock Text="{Binding Name}" Grid.Column="0" HorizontalAlignment="Stretch"   />

        <TextBlock Text=">>" Grid.Column="1" HorizontalAlignment="Right" Margin="5,0,5,0" />

   </Grid>

</DataTemplate>

RadListBox

<telerik:RadListBox MinWidth="100" MaxHeight="250" x:Name="radListBox"

Grid.ColumnSpan="2" Visibility="Collapsed"

HorizontalAlignment="Left" VerticalAlignment="Top"

ItemTemplate="{StaticResource AutoCompleteListBoxTemplate}"

PreviewKeyDown="radListBox_PreviewKeyDown">

<telerik:RadListBox.Effect>

<DropShadowEffect ShadowDepth="10" Color="Gray" Opacity=".4" Direction="320" RenderingBias="Performance" />

</telerik:RadListBox.Effect>

</telerik:RadListBox>

You will notice that in my template I have grid where I'm trying to force the last column over to the far right of the ListBoxItem. For some reason this isn't working with both columns aligning to the left. If I build the grid not within a ListBox template then it works.
I'm trying to make the last grid items align no matter the length of the content in the column before it.

Could the cause be that I'm using the Office_BlueTheme()?

****** EDIT ********
I tried removing the theme but it doesn't make a difference.

Thank you for your time.

RadTreeViewItem MouseDoubleClick Event Using MVVM

Hi,

I have a problem how to declare the MouseDoubleClick event using XAML in The MVVM pattern. For the the event associated to the RadTreeView I do not have problem. I do like this in my XAML:

<telerik:RadTreeView .......>

<i:Interaction.Triggers>

<i:EventTrigger EventName="LoadOnDemand">

<vm:InvokeDelegateCommandAction Command="{StaticResource loadOnDemandCommand}"

CommandParameter="{Binding RelativeSource={RelativeSource Self, Path=InvokeParameter}"/>

</i:EventTrigger>

<i:Iteraction.Triggers>

</telerik:RadTreeView>

In the code snippet, I have created a command named loadOnDemandCommand which is associated to the LoadOnDemandMethod in the viewModel when the LoadOnDemand event fires.

How can I do in XAML to declare a DoubleClick event which fires after double clicking on the RadTreeViewItem.

Thanks for your precious Help.

Context Menu from radPane

Whenever I add a radGridView to a radPane the radGridView seems to inherits the radPane's Context menu as its context menu. If I right click on a gridView on a radPane it has the context menu of floating, dockable, tabbed document, auto hide and hide and if I select one of them it will do that to the pane the grid is contained in. Even if I set the gridView context menu to null after InitializeComponent I still have the radPane context menu when I right click on the gridView. It does not do this for other controls on the radPane just the gridView.

How can I stop this from happening?
Thanks

Selection handles

In running the RadControls demo, I noticed that the older version of the RadTimeBar (Q2 2011) has little left/right arrows in the selection handles, where as the newer version (Q1 2012) does not. Is there a way to turn the arrows back on in the newer version? I've attached a picture of the older demo vs newer demo. The top picture is the new version and the bottom picture is the older version.

GridView GroupedRow doesn't line up & GroupRow edit

I was wondering if someone had a solution to get the Grouped Row headers to line up with the rest of the data. Someone posted a similar topic on the Silverlight forum: http://www.telerik.com/community/forums/silverlight/gridview/aggregate-result-display.aspx but the example project doesn't work for me in WPF, even with a little massaging.

Also, I was wondering if the GroupedRow header values (The aggregate values) could be editable?

Thanks

Tristate Mode behavior

I am using one of your example codes and seeing a different behavior when running the Project between .NET Framework 4 and 3.5 Framework in the Target framework property of the Project.
When I run in 4, I get a RED line between two Parent nodes. If I run in 3.5 I am not getting that red line.

This Red line appears when the Tree is in Tristate mode. It disappears when all the nodes are selected. Have you guys seen this problem?

Is this a bug? I am attaching screen shot of this.

I have used the example shown in this post.

RadGrid and GridViewComboBoxColumn Binding problems

Hi,

I am using WPF Telerik controls in a WPFApplication using MVVM pattern.

All controls binding is throw ObservableCollections, for the RadGrid the binding is fine but for the GridViewComboBoxColumn binding it's not.

In fact GridViewComboBoxColumn is binding to another ObservableCollections via
ItemsSource="{Binding MyCollection}"
DataMemberBinding="{Binding Property}"
DisplayMemberPath="Label"
SelectedValueMemberPath="Value"

but it doesn't work.

Can GridViewComboBoxColumn support another collection binding other than RadGrid Collection Binding ??

Thx
