I have a GridHyperLinkColumn in my radgrid that is used to link to a SSRS report on a per-row basis - I would like to add a header link button that allows the users to execute a report that generates a report of all row items (1 record per-page). To my mind setting the HeaderImageUrl and HeaderButtonType to LinkButton should result in a HyperLink control being rendered in the header cell however that is not the case - all I get is a Image control with the referenced image I set. It appears that setting the HeaderButtonType has no effect so I'm wondering what column types is this property valid for as it does not seem to be valid for a GridHyperLinkColumn. Obviously I could use a template column but I thought if I could use the properties provided (HeaderImageUrl/HeaderButtonType) life could be much simpler - that appears to not be the case.
<telerik:GridHyperLinkColumn UniqueName="MemoColumn" ImageUrl="Content/Images/memo16.png" Target="_blank" HeaderImageUrl="Content/Images/memo16.png" HeaderButtonType="LinkButton"> <ItemStyle HorizontalAlign="Center" Width="3%" Wrap="false" /> <HeaderStyle HorizontalAlign="Center" Width="3%" /> </telerik:GridHyperLinkColumn>
