Hi, 
I have a problems, I want to remove the checkbox, but I don't know how to do it  with OperatorValueFilterControlStyle.
And,Is there any solution other than using OperatorValueFilterControlStyle?
Help me for this problems.
tks.

My TreeListView is identical to the example provided in the "On-Demand Data Loading" example of you provided in the WPF Controls Examples. 

I'm interested in showing the Busy indicator when expanding a node (loading child data) when the data pull takes a little longer. 

Can you provide an example tailored to the TreeListView On-Demand Data Loading example to show how to achieve this?

Thanks,
Jason

I am changing themes for the application on the fly using 



However this does not seem to get applied for RadGridViews which have already been created. How do I force the theme to refresh for these controls?

Hi,

I have created one demo project for my wpf application in which i want to create table into Pdf

will throws an exception of "object reference not set to an instance" in function prepare 
document() at line   "document.Measure

I'm trying to get all distinct values of a column but keep getting an empty collection.

I'm using this code:


any idea?

thanks

I have a WPF form with a combo-box loaded with pole data. When a user selects a specific pole a RadGridView is bound to a data source representing all the equipment attached to that pole. Equipment data has a foreign key (parentid), that references the primary key of the same table it resides because a piece of equipment can be attached to another piece of equipment, so in essence, I have a RadGridView of Equipment with Hierarchical children. All row have a plus sign to the far left of the column providing access to view child equipment belonging to that row. So far everything looks great with one exception, the child at the end of the list has a plus sign and when clicked displays an empty row. How can I design this grid to hide the plus icon for equipment data with no children. My current xaml is shown below.

Hi,

I am using GridViewImageColumn to bind the images at runtime to GridView. When I try to filer/Group this Image column, image source path is showing. I just wanted to change the Filter text.

For Example, I have a Status colun where I show Pass/Fail images. When I filter or group this column, Image source path is showing. So, here I just wanted to show Filter or group text as Pass and Fail rather than pass/fail image path.

Hi,

First of all, thank you for your beautiful controls, they are amazing.

I am new to telerik, and I want to export some controls into a PNG, PDF, and also print them.

I found some samples in your demos but they take a control (for example chart), and put it in a PNG, but what I need is to take all controls (a few charts, pies, grids, etc) and put all of them into one PNG.

Can anyone help me?
Thanks in advance, :)

Hi.
I'm currently evaluating Telerik controls, and I am having an issue with RadWindow. A key scenario is to observer how our dialogues display when the DPI is set at its extreme.

My RadWindow has SizeToContent set to true, and IsRestricted set to true.
It's a tall dialog, and my assumption was, when the display is set to a high DPI (200% in Windows 8), the dialog will shrink to cover the range from top of the screen, to top of the taskbar (at which point the scroll bars would activate).

However, instead, part of the title and the bottom part of the dialogue are either offscreen, or obscured by the task bad.

I've attached a screenshot detailing the issue (I've blurred parts of the dialog intentionally).

In an effort to address the customization issue of the QAT, I attempted to add a contextmenu for the RadRibbonButtons. However, from what I can tell, the ContextMenu has to be of type Windows.System.Controls.ContextMenu, which doesn't get themed correctly. 

Is there a way to use a contextmenu that picks up the correct theme/style being applied to the rest of the Telerik controls?

Cheers
