asp.net c#弹出确认/取消对话框

Question

你这是Web应用。你这种功能不可能实现。当你实现弹出对话框的时候，这一次请求就已经结束。下一次请求不会从弹出对话框的位置继续执行。

Answer 1

webform,用js写个相应的方法，然后指定onclick事件。判断的话用confirm
winform,if (MessageBox.Show("确定", "提示", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
    //do sth
}
else
{
return;
}

Answer 2

JS操作
Confirm("你确定要怎的？");如果是服务端控件:OnClientClick

Answer 3

在page_onload事件里给你要点击的按钮添加如下属性
 this.SubmitButton.Attributes.Add("onclick", "return confirm('你确定提交吗？');");

Answer 4

一、使用GridView控件
    <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
                                                CellPadding="4" Font-Size="9pt" ForeColor="#333333" GridLines="None" OnPageIndexChanging="GridView1_PageIndexChanging"
                                                OnRowDataBound="GridView1_RowDataBound" OnRowDeleting="GridView1_RowDeleting"
                                                Width="500px">
                                                <FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
                                                <RowStyle BackColor="#E3EAEB" />
                                                <Columns>
                                                    <asp:BoundField DataField="ST_l_id" HeaderText="地址ID" />
                                                    <asp:BoundField DataField="ST_l_name" HeaderText="网站名称" />
                                                    <asp:BoundField DataField="ST_l_url" HeaderText="链接网址" />
                                                    <asp:HyperLinkField DataNavigateUrlFields="ST_l_id" DataNavigateUrlFormatString="AmendLink.aspx?ID={0}"
                                                        HeaderText="修改" Text="修改" />
                                                    <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
                                                </Columns>
                                                <SelectedRowStyle BackColor="#C5BBAF" ForeColor="#333333" Font-Bold="True" />
                                                <PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
                                                <HeaderStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
                                                <EditRowStyle BackColor="#7C6F57" />
                                                <AlternatingRowStyle BackColor="White" />
                                            </asp:GridView>
二、处理程序如：
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
SqlData da = new SqlData();
        da.ExceSQL("delete from ST_link where ST_l_id='" + GridView1.DataKeys[e.RowIndex].Value + "'");
Page.Response.Redirect("LinkManage.aspx"); 
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();//CodeGo.net
} protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((e.Row.Cells[1].Text).Length > 6)
{
e.Row.Cells[1].Text = (e.Row.Cells[1].Text).Substring(0, 6) + "…";
}
if ((e.Row.Cells[0].Text).Length > 6)
{
e.Row.Cells[0].Text = (e.Row.Cells[0].Text).Substring(0, 6) + "…";
}
if ((e.Row.Cells[0].Text).Length > 6)
{
e.Row.Cells[0].Text = (e.Row.Cells[0].Text).Substring(0, 6) + "…";
}
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
((LinkButton)(e.Row.Cells[4].Controls[0])).Attributes.Add("onclick", "return confirm('确定删除吗？')");
}
