Hi there,

 I'm sure this has been asked before. I have a column where the value needs to be represented by an icon. For example, I want the value of "1" to be represented by an image located in a local folder. Can I do this with a CellStyleSelector? Or do I need to use a CellTemplateSelector? Or is there any easier way to do this?

 

<telerik:GridViewDataColumn DataMemberBinding="{Binding Priority}" Header="P" Width="20">
       <telerik:GridViewDataColumn.CellTemplate>
           <DataTemplate>
                <Image Source="[WHAT GOES HERE?]" />
           </DataTemplate>
       </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

Thanks.

Hi David,

For achieving this, I suggest you using the built in GridViewImageColumn that RadGridView supports instead of GridViewDataColumn with a predefined template and CellStyleSelector.

I have also attached a demo application for your convenience. Can you please check it out and let me know whether it corresponds to your needs?

I see how the sample project you posted is changing the image, but I don't see how it's implementing a CellStyleSelector. From what I can see it's only implementing a straight GridViewImageColumn.

Can you show me how to implement a CellStyleSelector with a DataTemplate?

Hello David,

I am afraid that such requirements cannot be achieved through CellStyleSelector, as it defines a Style targeting GridViewCell. Note, that modifying the DataMemberBinding of a column through it is not possible. An appropriate solution for this case is to use CellTemplateSelector and define an Image control with its Source pointing to each needed image.

I hope the suggestion fits your requirements.

Best Regards,
