DataGrid-利用imagebutton实现删除操作

删除操作如图所示:

实现步骤:
1.在datagrid中创建模板列
2.在模板列中加入imagebutton并为其指定ImageUrl和CommandName,代码如下:

aspx代码
    <asp:TemplateColumn>
                                    <ItemTemplate>
                                        <asp:ImageButton id="ImageButton1" runat="server" ImageUrl="../Pic/delete.gif" CommandName="Del"></asp:ImageButton>
                                    </ItemTemplate>
                                </asp:TemplateColumn>

3.在datagrid的ItemCommand事件中添加如下代码

单击删除图标时触发
 private void DG_userinfo_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
        {
            if(e.CommandName=="Del")
            {
                string uid = e.Item.Cells[0].Text.ToString();
                string [] values = {uid};
                OperateXmlByDataSet.DeleteXmlRows(ViewState["filename"].ToString(),"userid",values);
                BindDG();

            }
            if(e.CommandName=="UpDt")
            {
                string userid = e.Item.Cells[0].Text.ToString();
                ViewState["uid"] = userid;
                this.Txt_id.Text = userid;
                this.Txt_name.Text = e.Item.Cells[1].Text.ToString();
                this.Txt_pass.Text = e.Item.Cells[2].Text.ToString();
                this.Txt_mail.Text = e.Item.Cells[3].Text.ToString();
                this.Txt_site.Text = e.Item.Cells[4].Text.ToString();
                this.Txt_msn.Text = e.Item.Cells[5].Text.ToString();
                this.Panel1.Visible=true;            
            }
        }

4.在datagrid的ItemCreated事件中添加如下代码

.cs代码
private void DG_userinfo_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
        {
            System.Web.UI.WebControls.ImageButton ib;
            foreach(DataGridItem item in this.DG_userinfo.Items)
            {
                ib = (ImageButton)item.FindControl("ImageButton1");
                ib.Attributes.Add("onclick","return confirm('您确定要删除？');");
            }
        }
