Server-side: enable tab doesn't affect control

[Eugene]

My code

 

    protected void Event(object sender, EventArgs e)
    {
        TopTabMenu.Tabs[1].Enabled = true;
    }

So the general idea is to enable a tab on some event (or condition).

According to http://www.telerik.com/help/aspnet-ajax/tab_tabsserverside.html
it should work, but nonetheless the tab is still disabled after this code is performed.

Can you help me?

Hello Eugene,

I tried enabling a tab in my RadTabStrip which is initially disabled on a button click and it works as expected. Check out the following code for any differences:
aspx:

  <telerik:RadTabStrip ID="RadTabStrip1" runat="server" >
     <Tabs>
         <telerik:RadTab Enabled="false" Text="Tab1" ></telerik:RadTab>
         <telerik:RadTab  Text="Tab2" ></telerik:RadTab>
         <telerik:RadTab Text="Tab3" ></telerik:RadTab>
     </Tabs>
  </telerik:RadTabStrip>

cs:

 protected void Button_Click(object sender, EventArgs e)
    {
        RadTabStrip1.Tabs[0].Enabled = true;
    }

Thanks
Princy.

Probably, the root cause can be that code which is enabling tab is located in an *.ascx file (which is included) to a *.aspx - which declares a TabStrip.
Finally I solved it by enabling on client side (i.e. using javascript).

So the code actually was (in ascx):

    protected void Event(object sender, EventArgs e)
    {
        ((RadTabStrip)Page.FindControl("TopTabMenu")).Tabs[1].Enabled = true;
    }
