How to enable dragover Auto Expand

We are using the Radtreeview to show some virtual folders. We have a require ment to drop files inside the treeview.

ie, the end user can drag and drop the items from the windows explorer to the RadTreeView. But the treeview items does not automatically expands when the user drags the file over the treeview item.

We just like to do the same of windows explorer treeview drag drop functionality. The windows explorer (win forms) treeview automatically expands while drag over an item .

How to achive that in RadTreeview?

Hide Expand/Collapse

Hello,

My application looks like your example "firstlook".
I want to be able to hide expand/Collapse image if there are no child records. I saw the example N° 101300_HideExpandButton.
Today , is there an easier way to hide expand/Collapse ? (because this post dates september 18th, 2008)

Thanks.

Control Expander on SelectionChanged event

Hi,

I have WPF 2009 SP2 (2009.2.701.35). I am attempting to control the expander (+ - ) on the grid. I use the following event

PreviewDataRecordCreate for the intialization of the grid to control the expander which works well. However i would like to validate the expander when the user selects the row (selectinchanged event)
I have tried to cast to the ExpandableDataRecord but this is always null. I would like validate that the expander is valid i.e. i do have data for the child grid. I am currently calling a rebind of the grid view but this does not help. I dont want to remove the row and re-add it as that seems to be a hack.

Secondly is there an event when the user clicks on the expander (+-) as this does cause a selectionchanged event?

The last question is that there is allot of classes marked as deprecated such as ExpandableDataRecord is there mechanism to look at which classes we should use instead as the forum posts would refer to the old classes?

Kind Regards,

Clinton

it is possible to not display a value?

I mean, suppose you have a line graph with 20 value but i don't want 4th and 8th values so that my line is broken because 4th and 8th values are invalid.
It is possible?

RadTabItem.ContentTemplateSelector

I am trying to bind a collection of workspaces to the RadTabControl and use a DataTemplateSelector to choose the DataTemplate for the content based on which type of workspace is being rendered but the RadTabItem does not appear to use the DataTemplateSelector that I set. Here is an example of my code:

    
                    <telerik:RadTabControl ItemsSource="{Binding Workspaces}"> 
        
                        <telerik:RadTabControl.Resources> 
        
                            <Style TargetType="{x:Type telerik:RadTabItem}"> 
        
                                <Setter Property="ContentTemplateSelector"> 
        
                                    <Setter.Value> 
        
                                        <local:TabItemContentTemplateSelector /> 
        
                                    </Setter.Value> 
        
                                </Setter> 
        
                            </Style> 
        
                        </telerik:RadTabControl.Resources> 
        
                    </telerik:RadTabControl>

I put a breakpoint in the SelectTemplate method but it never reaches it.

Has anyone got this to work?

TabStripPlacement not working as expected

Hello

I am using the wpf tab control and want the tabs to be on the left hand side with my content on the right hand side. I was looking into the documentation at (http://www.telerik.com/help/wpf/radtabcontrol-appearance.html) and saw that you can set the property "TabStripPlacement" to left. When I do this, the tab goes across the screen with my content below the tab.

I also look at the following page for silverlight (http://demos.telerik.com/Silverlight/#TabControl/TabStripOrientation) and your getting the same effect by setting the same property.

Example of what I want:
[tab1] content display for selected tab
[tab2]
[tab3]
...

Here is what I am getting:
[tab1]
[tab2]
[tab3]
Content below tabs

Where am I going wrong?

Thanks

Cannot add Column Dynamically

I just started using Telerik Grid instead of MS based Grid.
I just tried to Add and clear columns dynamically into the grid but I couldn't find the appropirate functions in intellisense.
I tried "this.radResult.Columns.Add(dyncol)" but, I Couldn't find "Add" in intellisense, couldn't find "Clear" method in intellisense as either.

At code behind side I am using following namespaces:

    
            using System;  
        
            using System.Collections.Generic;  
        
            using System.Linq;  
        
            using System.Net;  
        
            using System.Windows;  
        
            using System.Windows.Controls;  
        
            using System.Windows.Documents;  
        
            using System.Windows.Input;  
        
            using System.Windows.Media;  
        
            using System.Windows.Media.Animation;  
        
            using System.Windows.Shapes;  
        
            // Telerik using     
        
            using Telerik.Windows;  
        
            using Telerik.Windows.Data;  
        
            using Telerik.Windows.Controls;  
        
            using Telerik.Windows.Controls.GridView;  
        
            using Telerik.Windows.Controls.GridView.Cells;  
        
            // add using     
        
            using System.Collections.ObjectModel;  
        
            using System.Windows.Browser;  
        
            using System.ComponentModel;  
        
            using System.Collections;  
        
            using System.Windows.Controls.Primitives;

    
            void tabPreview_Loaded(object sender, RoutedEventArgs e)   
        
            {  
        
                BuildColumns();   
        
            }   
        
            private void BuildColumns()   
        
            {  
        
               this.radResult.Columns.Clear(); //<-- This method doesnt show in intellisense, neither Add method will show up here   
        
            }

Am I doing anything wrong here?
