从网格视图删除之前的消息框 [英] Message box before deleting from grid view

问题描述

你好，

我有一个包含编辑和删除按钮的数据库表的网格视图.如果用户单击一行的删除"按钮，我想问他/她:确定吗?"在带有两个按钮的消息框中(是/否).

我该怎么做?

Hallo,

I have a grid view of a database table including edit- and delete- buttons. If the user clicks the delete button of a row, I want to ask him/her, "Are you sure?" in a messagebox with two buttons (yes/no).

How can I do that?

推荐答案

<ItemTemplate>
<asp:LinkButton  ID="btn_Cancel"  runat="server" Text="Cancel" CommandName="cancel" OnClientClick="return confirm('Are you sure want to delete this record?')"   />
 </ItemTemplate>

请参见讨论

它可能会为您提供帮助.

it may helps you.

<asp:Button   runat="server" ID="lnkDelete" CausesValidation="False" Text="Delete"

                    OnClientClick="chkDelete();"  CommandName="Delete" ></asp:Button>

然后插入一个HiddenField控件

then insert a HiddenField control

<asp:hiddenfield id="hdelete" runat="server" value="0" xmlns:asp="#unknown" />

写这个脚本

write this script

<script type="text/javascript">
 function chkDelete()
        {
        if(confirm("Do u want Delete?"))
        {
        document.getElementById("ctl00_ContentPlaceHolder1_GridView2_ctl02_hdelete").value="1";
        }
        else
        {
        document.getElementById("ctl00_ContentPlaceHolder1_GridView2_ctl02_hdelete").value="0";
        }
        }
</script>

然后在row_deleteing事件中，

then in row_deleteing event,

int str = Convert.ToInt32(((HiddenField)GridView2.Rows[0].FindControl("hdelete")).Value);
       if (str == 0)
       {
           e.Cancel = true;
       }
       else
       {
           e.Cancel = false;
           // write code for delete


       }
