Is there a way that I can use the built in Drag and Drop handler while Dragging and Dropping in a RadTreeView, while modifying the DragCue message? I have a couple of my own rules that I use in a PreviewDragEnded function, and I would like to change the DragCue to show what is allowed or not.

For example, if I have a tree with
Tree
--Nest
---Bird
---Bird2

I can set the PreviewDragEnded function to check that you don't drop a Nest into a bird. If you do, then I use e.handled = true and ignore the drag and drop action. I would like for the DragCue to show that it is not allowed first, instead of just not allowing it after the mouse button is released. I can do this if I write the DragQuery, DragInfo, DropQuery, and DropInfo functions, but I want to use the Rad versions of these functions that already exist (except for the modified DragCue, of course).

Thanks for your help.

Can you please suggest how to itrate over each color in the main Palette when it is set to "web216". What I want is I should be able to set and get color by looping over each color in the palette with the help of an index.
eg:
var int myColor = web216[1]
and vice versa.

thank you very much.
regards.

Event trigger when FilteredSource is updated

Is there currently a way to trigger an event when the FilteredSource has been updated by the DataFilter? Something like a CollectionChanged event or FilteredCompleted.

Thanks,

Changing Control type durring AutoGen

Hello All,

I need to change the control type durring AutoGeneration of a property to a ListBox. In my case, I have an 'int' property which is the primary key in a list table. Since the table changes from time to time, I can't use an Enum type. So how can I change the control type at run-time?

Unable to design RadTreeView in Blend

Hi,

I'm having a problem with setting the RadTreeViewItem's CheckState property through the ItemContainerStyle of the RadTreeView. Specifically, I receive an error message every time I try to edit the xaml in design mode with Blend (versions 3 or 4 RC) and nothing gets rendered on the design surfice. The message is:

"The member 'CheckState' is not recognized or is not accessible."

I managed to reproduce the problem with a stripped-down version of the xaml:

    
            <Window x:Class="WpfApplication18.MainWindow" x:Name="Window" 
        
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"   
        
                    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"               
        
                    xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation" 
        
                    mc:Ignorable="d"   
        
                    Width="640" Height="480" 
        
                    xmlns:sys="clr-namespace:System;assembly=mscorlib">  
        
                <Grid>   
        
                    <telerikNavigation:RadTreeView IsOptionElementsEnabled="True">              
        
                        <telerikNavigation:RadTreeView.Items> 
        
                            <sys:String>Item 1</sys:String>               
        
                            <sys:String>Item 2</sys:String>               
        
                            <sys:String>Item 3</sys:String>      
        
                        </telerikNavigation:RadTreeView.Items> 
        
                        <telerikNavigation:RadTreeView.ItemContainerStyle> 
        
                            <Style TargetType="{x:Type telerikNavigation:RadTreeViewItem}">  
        
                                <Setter Property="CheckState" Value="On" />   

                                <Setter Property="OptionType" Value="CheckList" />                   
        
                            </Style> 
        
                        </telerikNavigation:RadTreeView.ItemContainerStyle> 
        
                    </telerikNavigation:RadTreeView>         
        
                </Grid> 
        
            </Window>

It's only the CheckState property that's causing the problem (the OptionType property from the sample works fine).
Sources on the internet suggest tha an internal exception in the property 'setter' might be causing such behavior but that's just a clue.
Do you have any idea how I can get it working in Blend ??

Hi All,

Our requirement is to open multiple Telerik window control but it should not be like MDI window or another WPF window.

Something similar to Infragistics window control for WPF.
