ItemDataBound called twice for GridItemType.Header

[Martin]

I have        
void rgtClients_ItemDataBound(object sender, GridItemEventArgs e)
{
switch (e.Item.ItemType)
{
                case Telerik.Web.UI.GridItemType.Header
....
}
but what is happening the case Telerik.Web.UI.GridItemType.Header is executed twice for the same e.Item.ItemIndex) 
So I have to keep track which row I am at, with if (intCurrentGridIndex != e.Item.ItemIndex)
What will cause such behavior? Should't it be iterating through rows, including header?

Hello,

 Normally the ItemDataBound event should be called only once for each item that is created. If it is called twice there are most likely two HeaderItems in the grid depending on how you have configured the control and whether you have any additional code that interacts with the items.
It will be helpful if you can share the markup for the grid and any related code-behind so we can check it on our side and let you know what is causing the problem.

Kind regards,

Thank you for getting back to me, headers are defined as so
                    <telerik:GridTemplateColumn>
                        <HeaderTemplate>
...
Also two header rows contain a checkbox
I hope this help

Hello,

 Can you share the full markup of the grid so we can have a better idea of what is your full configuration. A screenshot with the two header rows will also be helpful.
