数据列表中链接按钮的Onclick事件 [英] Onclick Event of a linkbutton in datalist

问题描述

我正在尝试触发放置在数据列表中的链接按钮的Click事件，并且我正在使用以下代码


ASPX页面

I''m trying to fire the Click event of the linkbutton placed inside a datalist,and i''m using the following code


ASPX Page

<asp:LinkButton ID="LinkButton1" runat="server" Font-Names="Bertham" Font-Size="X-Large"

                            Font-Underline="False" CommandName = "answer">"<%#Eval ("Question") %>"</asp:LinkButton>

页面后面的代码

Code Behind Page

protected void DataList1_ItemCommand(object source,System.Web.UI.WebControls.DataListCommandEventArgs e)
   {
       if (e.CommandName == "answer")
   {
       Response.Write("<script language = 'javascript'>alert('U Clicked The Linkbutton'</script>)");
       Response.Write("Hello");
       //Response.Write("Hello");
   }
   }

如果只有一个条件，则可以删除if，并在grid databound event上执行此操作，因为当您使用item命令时，它会回发并在响应之后.

if you have only one condition, you can remove if , and do this on grid databound event , because when you use item command it post back and after it response you.

protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
        {
            LinkButton btn = (LinkButton) FindControl("lnkbtn");
            btn.Attributes.Add("onclick","alert(you are leaving this page!)");
        }
