row data bound problem

i am usin rowdatabound event of gridview to do some formating in gridview column. But when i execute the code and debug it using immediate window i do not get anything in e.Row.Cells[1].Text. I am populating the gridview from a datatable. It is displaying the records but i dont know why is it not getting in rowdatabound.

following is my code for binding

<asp:GridView runat="server" AutoGenerateColumns="False"  
                        ID="gviewTemplate" onrowdatabound="gviewTemplate_RowDataBound" DataKeyNames="F1"
                        onrowcommand="gviewTemplate_RowCommand" 
                        onrowediting="gviewTemplate_RowEditing" 
                        onrowcancelingedit="gviewTemplate_RowCancelingEdit" 
                        onrowupdating="gviewTemplate_RowUpdating">
                        <Columns>
                            <asp:TemplateField>
                                <EditItemTemplate>
                                    <asp:Label ID="lblID" runat="server" Text='<%# Bind("F1") %>'></asp:Label>
                                </EditItemTemplate>
                                <ItemTemplate>

                                <ItemTemplate>
                                    <asp:Label Runat="server" Text='<%# Bind("F4") %>' ID="lblCouponText"></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>

and this is what i am doing in rowdatabound

protected void gviewTemplate_RowDataBound(object sender, GridViewRowEventArgs e)
{
        if (e.Row.Cells[1].Text != e.Row.Cells[2].Text)
        {
            e.Row.BackColor = System.Drawing.Color.Red;
        }
 }

i cant understand if the records are being displayed in grid the why cant i get it in rowdatabound

Because you are using the template field in the grid , so try to debug and hold the cell then try to find the textbox inside it and then read it's value

try this:
you need to check for the rowtype because in row databound it also includes header,footer as well

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow & (e.Row.RowState == DataControlRowState.Normal | e.Row.RowState == DataControlRowState.Alternate)) {
            //your code here
        }
    }
