RadFormDecorator and RadGrid Issue (GridButtonColumn image not displayed)

[AndreaT]

Hi,

In a master/content page website I have a content page which hosts a RadFormDecorator, used to docorated a search panel and a RadGrid. The grid has Vista skin. The grid has a classic GridButtonColumn:

<telerik:GridButtonColumn ConfirmText="ELIMINARE l'elemento Selezionato?"
                    ButtonType="ImageButton"
                    ImageUrl="~/admin/images/Delete.gif"
                    CommandName="Delete" Text="Elimina Elemento"
                    UniqueName="DeleteColumn">
        <ItemStyle HorizontalAlign="Center" />
    <HeaderStyle Width="30px" />
</telerik:GridButtonColumn>

when th page is first loaded the images are not displayed. The images are displayed back if I select a row or an ajaxified refresh is forced.

I removed the decorator and the images are displayed properly.

Any advice?

Thank you
Lorenzo

Lorenzo,

Is this the latest Q2 2008 version you are running? I remember Telerik announced better integration with the FormDecorator control with that version.

Otherwise, you can work-around the problem through decorating zones:

or by excluding the image buttons from the decorated controls.

No way, Leon. Seems that RadFormDecorator is incompatible with radgrid. I tried all of possible combinations, but I does not work.

Moreover I found that hitting the browser refresh button RadFormDecorator-RadGrid combination raise a javascript error:

 function Sys$WebForms$PageRequestManager$remove_pageLoaded(handler) {
        var e = Function._validateParams(arguments, [{name: "handler", type: Function}]);
        if (e) throw e;

        this._get_eventHandlerList().removeHandler("pageLoaded", handler);
    }

Lorenzo, try out whether using decoration zones and excluding the grid from those zones styles by RadFormDecorator is applicable workaround for your case.

Kiara,

the workaround does not work. I think it is a bug and i will open a support ticket.
