Question

当用户选择下拉列表时，我正在尝试重定向到另一个网页，并且一旦用户单击提交按钮，就应该将用户重定向到另一个网页。这是我的下拉列表和按钮的代码。点击“点击继续”按钮，用户应根据列表选择进入下一个网页。我刚接触.Net请提前帮助谢谢!!

         <asp:DropDownList ID="DropDownList1" runat="server" 
        onselectedindexchanged="DropDownList1_SelectedIndexChanged">
        <asp:ListItem Value="-1">Select User</asp:ListItem>
        <asp:ListItem Value="staff">Staff</asp:ListItem>
        <asp:ListItem Value="student">Student</asp:ListItem>
        </asp:DropDownList>
        <br />
        <br />
         <br />
             &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
         <asp:Button ID="Button1" runat="server" onclick="Button1_Click" 
            Text="Click to Proceed" />

Answer 1

在Button1_Click事件中，使用Response.Redirect方法将人员发送到相应的页面。

以下内容对您有所帮助。

protected void Button1_Click(object sender, EventArgs e)
{
    string sel_val = DropDownList1.SelectedValue; // use sel_val to apply if, else logic to redirect to
    // some possible examples
    if (sel_val != "-1") // as SelectedValue is string
    {
        // assuming there is staff.aspx, and you want to redirect to that page on selecting staff, this is just an example
        Response.Redirect(sel_val + ".aspx"); // use this to redirect to required page
    }

}

同样更改这样的aspx代码。注意我已从OnClick更改了onclick。

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Click to Proceed" />

根据asp.net中下拉列表的值加载另一个网页
