Hello Mitesh,

I cannot replicate the issue at my end. Your code is working as expected which returns the header text. If you are setting AutoGenerateColumns as true, try the following code to access the header text for each columns.
VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs)
    If TypeOf e.Item Is GridHeaderItem Then
        Dim item As GridHeaderItem = TryCast(e.Item, GridHeaderItem)
        For Each col As GridColumn In RadGrid1.MasterTableView.AutoGeneratedColumns
            Dim s As String = item(col.UniqueName).Text
        Next
    End If
End Sub

Thanks,
Shinu.

Hi Shinu,

Thanks for your help

Now I have another requirement, I need to add DropDownList control in existing column dynamically, I don't need add extra column for that

I don't have any ItemTemplate in my design,  my query is dynamic so I can't add ItemTemplate at design time so I need to add DropDownList control runtime (on ItemDataBound)

can you please help me on this ?

Hello Mitesh,

One suggestion is you can add a dropdownlist in Prerender event as shown below.
C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
   foreach(GridDataItem item in RadGrid1.Items)
   {
      foreach (GridColumn col in RadGrid1.MasterTableView.AutoGeneratedColumns)
      {
        if (col.UniqueName == "UniqueName")
        {
             DropDownList ddl = new DropDownList();
             ddl.ID = "DropDownList1";
             ddl.DataSourceID = "SqlDataSource1";
              ddl.DataTextField = "EmployeeID";
               ddl.DataValueField = "EmployeeID";
               item[col.UniqueName].Controls.Add(ddl);
          }
       }
    }
}

Thanks,
Shinu.
