I am trying to emulate Windows general behavior for editing treeview nodes: clicking on an already selected node enters the editing mode.
With RadTreeView (WPF) I can handle the previewMouseDown events, as well as the left and right mouse button preview events of the treeview.
In the event handler i call begin edit (TV.SelectedContainer.BeginEdit() or myradTreeviewitem.BeginEdit).
It does not work with a Left Mouse Click
In other words, BeginEdit does not work when called on a previewMouseDown if the left button triggered the event.
The PreviewMouseRightButtonDown works using the same handler.
The PreviewMouseLeftButtonDown works using the same handler.
Is there a reason why this is so. It is important for my application that I can keep windows interface conventions like clicking on the selected Tree Node enters editing mode.
Any help will be appreciated.
Thanks

AddHandler _TV.PreviewMouseDown, AddressOf tv_PreviewMouseDown
In the event handler i call begin edit (TV.SelectedContainer.BeginEdit() or myradTreeviewitem.BeginEdit).
Private Sub tv_PreviewMouseDown(sender As Object, e As MouseButtonEventArgs)This code works perfectly with a Righ Mouse click.
Dim s = TryCast(e.OriginalSource, UIElement)
If s Is Nothing Then Exit Sub
Dim Item = UI.Library.FindVisualParent(Of Telerik.Windows.Controls.RadTreeViewItem)(s)
If Item Is Nothing Then Exit Sub
If Item.IsSelected Then
_TV.SelectedContainer.BeginEdit()
' Item.BeginEdit
End If
End Sub
UI.Library.FindVisualParent is a small function that returns the parent of Type T of an element

When I have a scatter point series where xvalue mapping is a date time and the chart's horizontal axis is a DateTimeContinuousAxis I get nothing plotted.
I can't imagine I'm the only one wanting to plot time series data without using the line series?
Is there a way to use the line series but not draw the lines, but draw the points?

Dear All,
I want to add RadWindow in WPF Window as a child control like following:
<
Window x:Class="MDIApplication.Window1"
xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml
Title="Window1" Height="300" Width="300">
<Canvas>
<telerik:RadWindow Width="500" Height="300" BorderBackground="Yellow" BorderThickness="30" BorderBrush="Green" Visibility="Visible" />
</Canvas>
</
Window>
Now I want to move this child RadWindow inside the parent WPF Window, Just same as an MDI Child Window inside an MDI Parent Window.

From this page: http://www.telerik.com/help/wpf/raddatetimepicker-styling-calendar.html
It says that if I generate a style, I should get those resources at the bottom (i.e. HeaderBackground). This never happens. I get a style, but I can't change the background of the header. Basically I do not want any of the colors that are defaulted. I just want to specify new colors overriding ALL that are there.
Has anyone else gotten that to work?

Hi,
I have a question about the binding to a SQL-Database
The Database-Table looks like this:
Column value
id id
name name of the node
parentid id of the parentid (0=root)
how is the best way to fill a RadTreeView from this table with all its nodes?
Thank you for your help and sorry for my bad english

Hi,
I am printing GridView's and TreeListViews using the PrintAndExportWithRadDocumentModel.cs code, which I found on the forum somewhere.
I need to be able to hide the PrintDialog if required, how do I achieve this using the printing functionality of the RichTextBox. Previously I was using another class PrintExtensions.cs, but this was not able to print the TreeListView's which I need.
Thanks,
Adam

The code samples provide a mechanism for saving the file and then subsequently open Excel with the saved file.
We would like to follow a more standard paradigm with regards to exporting to Excel. We would like to stream the contents of the grid directly to Excel - similar to some other well know applications (e.g. SSRS). The saving of the file would then becomes the prerogative of the end-user.
Is there a way to do so?

I read several posts that stated that you were going to have the PDFViewer for WPF in Q3 SP 1. I just downloaded it and installed it and it is not there. What is the time frame on this?
