本来是：
private void DataGrid1_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
if (e.CommandName=="Item"){
Response.Write("dddddddddddddddddd");
}
}
我把IF 去掉也不行呀！！！！！？？
多谢!
<asp:ButtonColumn HeaderText="选取" Text="选取" CommandName="DS"></asp:ButtonColumn>
（2）如果要使用你那种方式，就要AutoGenerateColumns=Fasle,并对每一个字段进行绑定
如:
<Columns>
<asp:TemplateColumn HeaderText="编辑">
<ItemTemplate>
<asp:Button id="Button1" runat="server" Width="45px" Text="编辑" CommandName="Item"></asp:Button>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn DataField="姓名" HeaderText="姓名" > </asp:BoundColumn>
<asp:BoundColumn DataField="职务" HeaderText="职务" > </asp:BoundColumn>
</Columns>
<asp:DataGrid id="DataGrid1" style="Z-INDEX: 101; LEFT: 175px; POSITION: absolute; TOP: 78px" runat="server" Width="408px" Height="269px" AutoGenerateColumns="False">
<Columns>
<asp:TemplateColumn HeaderText="编辑">
<ItemTemplate>
<asp:Button id="Button1" runat="server" Width="45px" Text="编辑" CommandName="Item"></asp:Button>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn DataField="name" HeaderText="姓名"></asp:BoundColumn>
<asp:BoundColumn DataField="age" HeaderText="年龄"></asp:BoundColumn>
<asp:BoundColumn DataField="high" HeaderText="身高"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
怎么还不行呀?
确认你的事件是否真正触发了吗？
if(!IsPostBack）
{
Your Code;
}
如果不判断是否是PostBack，那么每一次刷新页面都会调用一次Page_Load事件，那么就会重新绑定数据，这时DataGrid就不会响应任何事件。
