Hello Dhamodharan,

In SelectedIndexChanged event of RadComboBox access the insert form using NamingContainer property of RadComboBox and then access corresponding control that you wants to hide using its UniqueName. Sample code is given below.

ASPX:

<Columns>
    <telerik:GridBoundColumn DataField="EmployeeID" UniqueName="EmployeeID" >
    </telerik:GridBoundColumn>
     <telerik:GridTemplateColumn>
         <EditItemTemplate>
            <telerik:RadComboBox ID="RadComboBox1" runat="server"
                DataTextField="FirstName" DataValueField="FirstName"
                 AutoPostBack="True"
                OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
            </telerik:RadComboBox>
        </EditItemTemplate>
    </telerik:GridTemplateColumn>
</Columns>

C#:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
  {
      RadComboBox combo=(RadComboBox)sender;
      GridEditFormInsertItem insertItem = (GridEditFormInsertItem)combo.NamingContainer;
      TextBox txtid = (TextBox)insertItem["EmployeeID"].Controls[0];
      txtid.Visible = false;
  }

Thanks,
Princy.
