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>

Hello,

Thank you for contacting us.

The properties that you are using are inherited from the base class(GridColumn) and are not implemented in the child class(GridHyperLinkColumn). That is why you are not seeing visual or functional difference when you set them.

Thank your for pointing that out, we will consider which properties should be implemented and which one should be hidden so it does not confuse our customers.

You could use our PITS system to monitor the process:

You can follow the PITS Issue by its ID: 11611

Let me know if I can be of any other help.

Personally, I think they should be valid attributes on the RadGridHyperLink column given that the row column is designed to be a hyperlink - I see no reason why the column header control could not be generated based on the attribute values.  Regardless, I have come up with a work-around that does not involve using a template column - I set a onclick handler for the column header image (that is being generated) to open the report url in a new window.

Hello,

Most of the scenarios that our clients use does not involve hyperlink in the header, however, will consider implementing this feature as it could be useful in some rare cases.

Hello Dan,

There are also other ways you can achieve this requirement. One option is to use ItemCreated/ItemDataBound and access the header cell of the header item and add a new HyperLink or LinkButton to its Controls collection.
