Is there a way to auto-close one RadExpander when another RadExpander is expanded?

Hello!

Is there the possibility to set MinHeight & MinWidth to the document host so when the user is resizing the window the DocumentHost would not go shrunk under the specified values?

Thank you!

Hi,

I use programmatically columns generation:


for GridView:


But I can't see ToolTips for columns.
What is problem?

Thanks!

I've got a custom style for my RadGridView in my WPF application.  Before I started editing the style, I remember that the RadGridView used to show the selected row by changing the background color (I think). After editing the style, my control isn't doing this any more.

Can you point me to the style, or provide it in a response to this thread?

Thanks

I am finding drag and drop really difficult to implement. I have tried to modify the DragandDrop example in RadListBox by adding a treeview in a column next to the Group A-D listboxes, modified the code to populated it with a couple country objects, but could not work draganddrop from this radtreeview to listboxes work. I also would like to enable reorder in the radlistbox as well.

I can post my solution here, but do not want to include the binaries etc.

Could someone quickly write a small demo, by modifying the demo little bit? I guess I need to use (maybe?) RadDragandDropManager and DragandDrop at the same time, but a sample project would help a lot.

Thanks.

I have the following xaml:


On the UserControl loaded event I have the following:

Most of the time this works fine. However occasionally the FindCarouselPanel will return null instead of the panel? Am I doing something wrong? Is there anything I can do to prevent this?

since braking changed on for the Q1-2012 version your ColumnFilterDescriptor is not internal and was public..   :( 
I use to inherits this class for a special feature for filtering a "flagable enum"

Since it is cannot be inherits anymore, I try ro create my filter again

big lines:
1. standard "disctinct values"
2. an enum that have multiple state are included in filter even if the values is not "EQUALS" but contains...


My problem reside on the "yellow hilighted line."

Hello Telerik Team,

Hi,

I am using telerik treeview control alongwith ,NET System.Windows.Interactivity to implement the drag and drop feature.

Recently i upgraded to version 2012.1.0326.40 and since then the drag and drop feature has stopped working.

Reverting to the older version of 2011.2.0920.40 with same code makes drag and drop works.

Appreciate your help on the same.

Hi,

I am in the process of evaluating Telerik Gridview.  Our data is organized in groups.  I created a RadGridView that uses 1 column as a GroupDescriptor.  I noticed that the scrolling through each grouped table is VERY slow as each group is expanded (AutoExpandGroups="True").  The performance is better if I remove GroupDescriptor altogether.  Here are what I set in my RadGridView:

<code>CanUserFreezeColumns="False" RowIndicatorVisibility="Collapsed"  AutoGenerateColumns="False" IsReadOnly="True" ScrollMode="Deferred"   telerik:StyleManager.Theme="Metro" FontSize="11" ShowGroupPanel="False" RowHeight="18" Grid.Row="1"  Width="1320" MaxWidth="1320" MinHeight="800" MaxHeight="1000"</code>

Is there anything I can do to increase the performance.  The table size is around 14000 cells.  

I saw this earlier post and it was stated that the issue was resolved. I can't download the code as I am not yet a licensed user.

Please advise.  Thanks.
