Hi Rahul,

I guess you are trying to access the CheckBox inside a GridTemplateColumn in code behind. If so you may try the following code snippet to achieve the desired scenario. If not you may consider sending your aspx page.

//here is the code to access template controls in code behind
ASPX:

<telerik:GridTemplateColumn UniqueName="CheckBoxCol"  HeaderText="CheckBoxCol" >
          <ItemTemplate>
              <asp:CheckBox ID="CheckBox1" runat="server" />
          </ItemTemplate>
         </telerik:GridTemplateColumn>

VB:

  Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
        If TypeOf e.Item Is GridDataItem Then
            Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim chkbx As CheckBox = DirectCast(item("CheckBoxCol").FindControl("CheckBox1"), CheckBox)
        End If
    End Sub

You can use the column's UniqueName property to access the cells in RadGrid.
