I was looking at using the StyleSelector to do some conditional formatting in our grids. Originally we did this by adding a custom binding in the RowLoaded event because the selector wasn't working right (several releases back).

Anyway, I am now revisiting the StyleSelector (build 2011.1.322.1040), and it seems to work except for the fact that it is only used on every other row. It seems that if you use a style selector in conjunction with AlternateRowStyle, the selector is ignored on rows that have the alternate style, even if the properties being set in the 2 styles do not overlap. My style selector uses styles that only set the Foreground color, while the alternate row style sets the background color. Shouldn't the styles be merged?

Has anyone else seen this?

Hi Morgan,

 

The behavior you described is the expected one. When you have combined a style targeted at GridViewRow and GridViewRow StyleSelector, the style always takes predecence, it is by design. This is the reason by which the defined StyleSelector is ignored. In such cases you may define only a single StyleSelector that corresponds to your custom needs.


If you need any additional information please let us know.

Oh. That's unfortunate. So you can't use alternating styles at the same time. So, I would need to re-implement my alternating row style in the custom StyleSelector, yes? How would I do that?

Hello Morgan,

 

You may define an AlternateRowStyleSelector in the same way as it can be done with RowStyleSelector, please refer to the markup below:

<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding}" AlternateRowStyleSelector="{StaticResource styleSelector}" > .... </telerik:RadGridView>


Furthermore if you need to set only the background for these alternate rows why not just set the AlternateRowBackground property of RadGridView to specific colour. Then you may apply the RowStyleSelector in an appropriate manner.


Please let me know how this works for you.

 

Best wishes,

Hi Vanya,

I have set the AlternateRowBackground to "PapayaWhip" but RowStyleSelector is still ignored for the rows where Alternate is activated.

is there any other workaround ?

Bek
