前台代码：
<asp:datagrid id="dg" runat="server"
...
<HeaderTemplate>
<center>操作</center>
</HeaderTemplate>
<ItemTemplate>
<asp:linkbutton CssClass="button" ID="lbView" Runat="server" OnClick="lbViewClick">查看</asp:linkbutton>&nbsp;
<asp:linkbutton ID="lbEdit" Runat="server" OnClick="lbEditClick">编辑</asp:linkbutton>&nbsp;
<asp:linkbutton ID="lbDel" Runat="server" OnClick="lbDelClick">删除</asp:linkbutton>
</ItemTemplate>
...后台代码： protected void lbViewClick(object sender,EventArgs e)
{
LinkButton nmm_lbTmp;
int nmm_intID = 0;
for (int nmm_intNum=0;nmm_intNum<this.dg.Items.Count;nmm_intNum++)
{
nmm_lbTmp = (LinkButton)this.dg.Items[nmm_intNum].FindControl("lbView");
if (nmm_lbTmp.ClientID == ((LinkButton)sender).ClientID)
{
nmm_intID = Convert.ToInt32(this.dg.DataKeys[nmm_intNum]);
break;
}
} Server.Transfer("page.aspx");
}
