asp.net gridview rowcommand事件

Question

想要的效果就是点击删除按钮，弹出一个隐藏层，在层内输入密码并验证正确后，删除相应的记录
现在是点击删除后一闪，能看到div层 然后就直接提示密码错误，跳转到gridview列表<asp:ImageButton CommandArgument='<%#Eval("id") %>' CommandName='Del' OnClientClick="showDiv()" ID="ImageButton1" runat="server" ImageUrl="images/gtk-del.png" AlternateText="删除" />层
<div id="popDiv" class="mydiv" style="display:none;">
密码：<asp:TextBox ID="TextBox1" runat="server" TextMode="Password" ></asp:TextBox>
<br />
<asp:Button ID="BttLogin" runat="server" Text=" 提 交 " OnClick="BttLogin_Click" />
<asp:Button ID="Button1" runat="server" Text=" 取 消 " OnClientClick="closeDiv()" />
</div>后台代码
if (e.CommandName == "Del")
            {
                string username = HttpUtility.HtmlDecode(Response.Cookies["adminName"].Value);                string strSQL2 = "select * from admin where uname = '" + username + "' and pwd = '" + cls.MD5(TextBox1.Text.Trim()) + "'";                DataTable dt2 = cls.GetDataTable(strSQL2);                if (dt2.Rows.Count > 0)
                {
                    DataTable dt = cls.GetDataTable("SELECT * FROM list WHERE id = '" + e.CommandArgument.ToString() + "')");                    dt.Dispose();                    string strSQL = "Delete From list Where id  = " + e.CommandArgument;                    if (cls.GetSQLExecuteRows(strSQL) != -1)
                    {
                        cls.MsgBox("信息删除成功！");
                    }
                    else
                    {
                        cls.MsgBox("出现错误！", "Back");
                    }
                }
                else
                {
                    Response.Write("<script>alert('密码不正确')</script>");
                }
            }asp.netgridview

Answer 1

把删除代码放到ScriptManager+UpdatePanel里面来<asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
    ...........这是你的删除代码
        </ContentTemplate>
</asp:UpdatePanel>
    

Answer 2

<div id="popDiv" class="mydiv" style="display:none;">
密码：<asp:TextBox ID="TextBox1" runat="server" TextMode="Password" />
<asp:Button ID="BttLogin" runat="server" Text=" 提 交 " OnClick="BttLogin_Click" />
<asp:Button ID="Button1" runat="server" Text=" 取 消 " OnClientClick="closeDiv()" />
</div>
function showDiv()
{
$("#mydiv").show();
return false;
}

Answer 3

由于你的linkbutton或者是imagebutton没有return false 所以没有阻止事件加上return false就OK了.

<script language="javascript" type="text/javascript">
    function showDiv() {
        document.getElementById('popDiv').style.display = 'block';
        return false;
    }
    function closeDiv() {
        document.getElementById('popDiv').style.display = 'none';    }
</script>这样吗

Answer 6

其实是把c#的控件换成html的按钮控件    因为c#的控件会刷新页面
