Answer 1

我直接给你粘我的代码,你有不明白的私信我.
前台:<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CssClass="tab" Width="700px" OnRowEditing="GridView1_RowEditing" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDataBound="GridView1_RowDataBound" OnRowUpdating="GridView1_RowUpdating" OnRowDeleting="GridView1_RowDeleting">
<Columns>
<asp:BoundField DataField="DepartmentName" HeaderText="部门名称" ItemStyle-Width="100px" />
<asp:BoundField DataField="DepartmentDes" HeaderText="部门简介" />
<asp:CommandField ShowEditButton="True">
<ItemStyle Width="100px" />
</asp:CommandField>
<asp:CommandField DeleteText="<span onclick="return confirm('确认删除吗?');">删除</span>" ShowDeleteButton="True">
<ItemStyle Width="100px" />
</asp:CommandField>

</Columns>
</asp:GridView>
后台:
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
//if (!AdminLib.CheckPowers(UserInfo, 89))
// Response.Redirect("/HHC/error.aspx?m=您没有删除管理员的权限，请联系管理员！");
int id = Utils.StrToInt(GridView1.DataKeys[e.RowIndex].Value, -1);
if (AdminLib.DelDepartment(id))
BindData();
}
