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,

Could you please share the vb.net code for accessing the header template in rowdatabound?

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,
