I have tried to redirect a selected value using the below code and it does not work for me..

Any suggestions are highly appreciated.

C#

    {
        Response.Redirect("http://professionaldirect.microsoft.com")
    }
    else if(DropDownList1.SelectedValue=="PDM Availibility")
    {
        Response.Redirect("https://expert.partners.extranet.microsoft.com/userprofile/")
    }
    else if(DropDownList1.SelectedValue=="Windows Azure Help")
    {
        Response.Redirect("http://www.windowsazure.com/en-us/manage/windows/")

Hi,

In your ASP.NET file (.aspx file), add AutoPostBack="true" to the ASP.NET tag of your drop down list.

Hope this helps.

I had set the autopushback to true.. that still does not work.

Both aspx and backed code posted here:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication7.WebForm1" %>

Solution 2

Add AutoPostBack="true" in your DropDownList aspx code. Like this ..

ASP.NET

<asp:dropdownlist id="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" autopostback="true" xmlns:asp="#unknown">
      <asp:listitem text="-----Select-----" value="0"></asp:listitem>
</asp:dropdownlist>

-- Updated Answer
Your camparison is wrong. For the below dropdown value

DropDownList1.SelectedText would be "Exclusive Content"
whereas
DropDownList1.SelectedValue would be "http://professionaldirect.microsoft.com"

ASP.NET

<asp:ListItem Text="Exclusive Content" Value="http://professionaldirect.microsoft.com">

Try changing this

C#

if(DropDownList1.SelectedText=="Exclusive Content") 
{ 
   Response.Redirect("http://professionaldirect.microsoft.com?Value="+DropDownList1.SelectedText) 
}
