Need GridHyperLinkColumn to Trigger Wait Graphic in RadAjaxLoadingPanel

[Jeremy Yoder]

I have a RadGrid with a GridHyperLinkColumn. When clicked, it calls a javascript function that takes several seconds to run. I have a RadAjaxLoadingPanel set to run the wait graphic against the Grid, which works for other things on the Grid when a postback occurs. The GridHyperLinkColumn is as follows...

<telerik:GridHyperLinkColumn HeaderText="" UniqueName="View" DataTextField="CheckType" DataTextFormatString="View"
    DataNavigateUrlFields="CheckNumber,CheckType"
    DataNavigateUrlFormatString="javascript:ViewCheck({0},'{1}')">
    <HeaderStyle Width="100px" />
    <ItemStyle HorizontalAlign="Right"/>
</telerik:GridHyperLinkColumn>

The javascript function "ViewCheck" works (accepting the grid row's fields and calling a WebMethod in VB code-behind). But because there's no postback, the wait graphic never shows. How can I get the wait graphic to appear over the Grid in this scenario?

Hello Jeremy,

You can explicitly show and hide the loading panel when needed through client script. You can read more about this in this help article and see a live example in this online demo.

I hope this helps.
