code behind - Row editing

private void BindFinancialeditdtls(int index)
{
    string notes;
    LblFinancial_Year_Id.Text = gvFinancialdtls.DataKeys[index].Value.ToString();
    string fromdate = gvFinancialdtls.Rows[index].Cells[0].Text;
    string todate = gvFinancialdtls.Rows[index].Cells[1].Text;
    if (gvFinancialdtls.Rows[index].Cells[2].Text.Length > 30)
    {
        notes = gvFinancialdtls.Rows[index].ToolTip;
    }
    else
    {
        notes = gvFinancialdtls.Rows[index].Cells[2].Text;
    }    
    
    txtCalfromdate.Text = fromdate;
    txtCaltodate.Text = todate;
    txtRemark.Text = notes;
}

protected void gvFinancialdtls_RowEditing(object sender, GridViewEditEventArgs e)
{ 
    BindFinancialeditdtls(e.NewEditIndex);
}

after editing , values applies to above textbox, but after saving the edited value by clicking Save Button outside grid. The edited row displays textbox instead of bound field, also new button named update & cancel are rendered.


how to avoid the textbox rendering in boundfield & update & cancel button in the edited row.

Thanks
