Hello Duy,

Try the following code snippet in order to access the control placed in HeaderTemplate.

ASPX:
 
 <telerik:GridTemplateColumn UniqueName="Temp"
        <ItemTemplate> 
        </ItemTemplate> 
        <HeaderTemplate> 
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> 
        </HeaderTemplate> 
    </telerik:GridTemplateColumn> 

CS:
 
    GridHeaderItem headerItem = (GridHeaderItem)RadGrid1.MasterTableView.GetItems(GridItemType.Header)[0]; 
    Label lbl = (Label)headerItem.FindControl("Label1"); 
    lbl.Text = "New Text"

You could use the following code if you want to access the control in ItemDataBound event.
CS:
 
    protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) 
    { 
        if (e.Item is GridHeaderItem) 
        { 
            GridHeaderItem headerItem = (GridHeaderItem)e.Item; 
            Label lbl = (Label)headerItem.FindControl("Label1"); 
            lbl.Text = "My Text"
        } 
    }

Hi Jinson,

Here is the VB version of the code posted by Shinu.

VB

Dim headerItem As GridHeaderItem = CType(RadGrid1.MasterTableView.GetItems(GridItemType.Header)(0), GridHeaderItem)
Dim lbl As Label = CType(headerItem.FindControl("Label1"), Label)
lbl.Text = "New Text"

 

VB

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)
    If TypeOf e.Item Is GridHeaderItem Then
        Dim headerItem As GridHeaderItem = CType(e.Item, GridHeaderItem)
        Dim lbl As Label = CType(headerItem.FindControl("Label1"), Label)
        lbl.Text = "My Text"
    End If
End Sub

 

I would also recommend the Telerik Code Converted we have which is an online tool for converting C# to VB or vice versa, see http://converter.telerik.com/. This could come handy in the future if you're finding examples only in C#.

 

Kind regards,
Attila Antal
