เรื่องก็มีอยู่ว่า...........Code (C#) protected void myGridView_RowDataBound(Object s, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int f = e.Row.RowIndex + 1;
Label lableIndex = (Label)(e.Row.FindControl("lableIndex"));
lableIndex.Text = f.ToString();
}
}
Code (C#) <asp:TemplateField >
<ItemTemplate>
<asp:Button id="Button1" runat="server" Text="บันทึก" OnClick="btnSubmit" BackColor="Silver" BorderColor="LightGray"
BorderStyle="Solid" Height="30px" Width="50px" ></asp:Button>
</ItemTemplate>
</asp:TemplateField>
Code (C#) protected void btnSubmit(Object sender, EventArgs e)
{
Label ID = (Label)myGridView.Rows[.......].FindControl("lblID");
}
