回复不在aspx页面中工作 [英] Post Back not working in aspx page

问题描述

大家好，



我是.Net的新手。我遇到了一个问题。我正在使用从Visual Studio 2010中的母版页继承的aspx页面。我发现PostBack不适用于LinkBut​​ton click事件& DropDownList indexChanged。虽然普通的Button& ImageButton工作正常。请帮我看DropDownList& LinkBut​​ton将工作......



这是我的完整代码。

Hi All,

I'm new in .Net. I've a faced a problem. I'm using an aspx page that is inherited from master page in Visual Studio 2010. I've found that PostBack is not working for LinkButton click event & DropDownList indexChanged. Though normal Button & ImageButton is working fine. Please help me how DropDownList & LinkButton will work...

Here is my full code.

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder_Body" runat="server">
<asp:DropDownList ID="ddlPageSelector" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlPageSelector_SelectedIndexChanged">
                                                    </asp:DropDownList>
</asp:Content>

protected void ddlPageSelector_SelectedIndexChanged(object sender, EventArgs e)
        {
            Response.Write(ddlPageSelector.SelectedValue);
        }

但是相同的代码在VisualStudio 2008中有效。

请帮帮我。 ..

But same code is working in VisualStudio 2008.
Please help me out ...

推荐答案

从代码中看来你的ASPX页面正试图找到一个名为 ddlPageSelector_SelectedIndexChanged 的事件处理程序，而你的代码是< b> DropDownList1_SelectedIndexChanged 。



我建议你重建解决方案，如果处理程序不存在，应该抛出错误。

From the code it seems that your ASPX page is trying to find an event handler named ddlPageSelector_SelectedIndexChanged while your code behind is DropDownList1_SelectedIndexChanged.

I would suggest you to rebuild the solution and that should throw an error if the handler does not exist.
