Adjusting filtered icon for all RadGridViews in an application

[Boardy]

In my application I apply the Windows7 theme by setting

StyleManager.ApplicationTheme = new Windows7Theme();

in the creation of the main window.

Unfortunately it is not clear to the end-user which columns have filters on them, so I thought about styling it. I found this thread on the forum where some things are explained.

I set to work and copied DistinctFilterControl.xaml and GridViewHeaderCell.xaml from the Windows7 theme source directory and adjusted them to my satisfaction. I can apply the GridViewHeaderCellStyle to the column by using

<telerik:GridViewDataColumn HeaderCellStyle="{StaticResource CustomGridViewHeaderCellStyle}"/>

So far so good. Now I want, of course, the style automatically applied to all data columns in my application. Is it possible to tweak this into the used theme? Or would it mean I have to create a complete new theme (e.g., Windows7bis)? Or is there a way to make a custom datacolumn that has this header style automatically applied? Or...

I don't want to end up with an application with half of the columns having my new style of funnel and the rest with the original themed funnel (because I forgot to set some property).

Thanks in advance.

Hello Boardy,

In order to apply the style to all GridViewDataColums, make it implicit.  For implicit style you can remove the name attribute from the XAML . So then the style will be applicable to all control of specified Target Type.

Thx Yoan. This works as intended. It seems it's enough to do this for the DistinctFilterControl.xaml. I don't even need the GridViewHeaderCell.xaml any more.
