Self-referencing hierarchy and PreRenderComplete

[Gilbert]

Hi,

I'm trying to set up the RadGrid for self-referencing using HierarchyLoadMode = Client. I'm seeing a lot of "No Child Records Found" in my grid and read that I need to hide them during PreRenderComplete. However, my grid is inside a usercontrol so the PreRenderComplete event doesn't fire. Under regular circumstances I should to fire the method in the Page's PreRenderComplete, but this usercontrol is being wrapped into a sharepoint webpart which I don't have PreRenderComplete event for.

Is there any other way to make it possible to hide the "No Child Records Found" nested table views? I can't hide it during PreRender because it is Client Load Mode.

Thanks,
Gilbert

Hello Gilbert,

In such case an easy solution would be to expose the grid object of the user control via a public property.
This way you can handle the Page_PreRenderComplete in your page(where you are referencing the user control) properly.

public void Page_PreRenderComplete(object sender, EventArgs e)
{
    RadGrid someGrid = (RadGrid)grd.GridObject;

    grd.HideExpandColumnRecursive(someGrid.MasterTableView);
}

I am also attaching a simple solution.

Best wishes,
