人们，有人可以告诉我如何在动态创建的数据表中的每一行中添加不同的按钮？我的DataTable绑定到GridView。我需要知道如何在这里添加：drCurrentRow [＆＃34; Button＆＃34;] =＆＃34;每行中的不同按钮＆＃34 ;;这是我的代码：
<asp:GridView ID="GridView2" runat="server" OnRowDataBound="GridView2_RowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="btnTest" runat="server" CommandName="odzemi" CssClass="button2" OnClick="btnTest_Click" Text="-" Width="100px" Font-Bold="True" />
<asp:Button ID="Button15" Visible="false" runat="server" Text="Button" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
//创建dataTable
private void AddDefaultFirstRecord()
{
//creating DataTable

DataRow dr;
dt.TableName = "Markici";
//creating columns for DataTable
