Set Value of Control in GridTemplateColumn HeaderTemplate

[perry]

 I am able to change the values of all the controls in my telerik grid in the ItemDataBound method except those in the HeaderTemplate
How can I access those controls?

 

<telerik:GridTemplateColumn UniqueName="TemplateColumnOne" >

<HeaderStyle >

</HeaderStyle>

<HeaderTemplate >

<asp:Label ID="lblToolTip" runat="server" ></asp:Label>

</HeaderTemplate>

<ItemTemplate>

<asp:Label id="lblPermitNumber" runat="server"></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

 

protected void Grid_ItemDataBound(object sender, GridItemEventArgs e)

{

var item = e.Item as GridDataItem;

TableCell documentColumn = item["TemplateColumnOne"];

var lblPermitNumber=(Label)documentColumn.FindControl("lblPermitNumber");

lblPermitNumber.Text = "some text; // how do you access LblToolTip ?

}

Hello Perry,

You need to use the correct item:

if (e.Item is GridHeaderItem)

That should do the trick.
