Hello Bennit,

For achieving this, you may modify the template of GridViewHeaderCell and remove the Border element with x:Name=Background_Over.

Please check the Override Default RadGridView Styles article  for further reference.

Hi Bennit,

 Please excuse me for this misunderstanding.

You actually need to remove the Border element with x:Name="GridViewHeaderCell_Over". It is located within the ControlTemplate with x:Key="GridViewHeaderCellTemplate" in Telerik.Windows.Controls.GridView.xaml file.

Hope this helps.

Hello Bennit,

What I meant in my previous post was to modify the default template of the control. The suggested approach in my previous post includes searching through the style file for the particular Telerik theme. the style files for all Telerik thems can be found in the Themes folder of your personal installation. Please check the Setting a Theme(Using Implicit Styles) topic for further reference.

Another approach would be to use MS Expression Blend as described in the Styling RadGridView article. You might also take a look at the Styling Column Headers article.

Hope this helps.

Stefan

Hopefully, this helps.

Stefan,

I ran the .sln you attached to see how it works but it displayed blank window (see attached). I'm fairly new to this WPF but the Style code defined in the example seems lengthy just for removing the color change on header mouseover. Is there a precise way to do it? Also noticed that telerik:RadGridView in the example is not applying the Style defined.

 

Thanks,

Srinu

Hi Srinu,

Thanks for the image provided.

From it I assume that you have applied NoXAML binaries. If this is the case, you need to also merge the needed theme files. Please, take a look at the Implicit Styles topic for a detailed explanation of this topic.

As to your other questions. The built-in mechanism provided by the framework for modifying the template of a control is the one demonstrated in the previously attached sample project. I am afraid, that I cannot provide an alternative. Also, the Style defined is not applied to RadGridView, as it is an implicit one. I suggest you reviewing the Using WPF Styles topic for more information on this matter.

I hope you find these resources helpful.
