access tabstrip from usercontrol on tab

[newbie]

I have a tabstrip on my page with several tabs and each tab has a usercontrol.
On one of my tabs based on a certain condition, I want to disable the other tabs.

Can you help me achieve this. I am unable to get a reference to the tabstrip from within the user control. I am using the latest build of ASP.NET AJAX controls.

Please help.

Hi,

Here's an example of how to access the RadTabStrip from within the UserControl nested in its tab:
ascx.cs:

protected void Page_Load(object sender, EventArgs e)
    {
        UserControl user = (UserControl)sender;
        RadTabStrip tabstrip = (RadTabStrip)(user.NamingContainer.FindControl("RadTabStrip1"));
        foreach (RadTab tab in tabstrip.Tabs)
        {
            if (//custom condition)
            {
                tab.Enabled = false;
            }
        }
    }

Hope this helps..
Princy.

I have tried to convert the cs code below to vb using telerik converter but it gave me this error:

CONVERSION ERROR: Code could not be converted. Details:

-- line 1 col 11: invalid TypeDecl

Please check for any errors in the original code and try again.

Will you provide me with the VB code version please?
Thank you.

Hi Illumination,

This is the converted VB code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    Dim user As UserControl = DirectCast(sender, UserControl)
    Dim tabstrip As RadTabStrip = DirectCast(user.NamingContainer.FindControl("RadTabStrip1"), RadTabStrip)
    For Each tab As RadTab In tabstrip.Tabs
        If ("Custom Condition here") Then
            tab.Enabled = False
        End If
    Next
End Sub

All the best,

Hi,

Thanks for the solution above t solved half of my problem. The other half of the problem is that I want to enable the tabs from my button click event.How do I achieve that?

Hi Spyros,

You can find the RadTabStrip control and use the foreach to go through all the tabs and set their Enable property to true.

That's what I'am doing currently unfortunately ajaxfication prevents me of just looping and enabling the tab. 

So my next question is how do i achieve this with Ajax?

[Kate]

Hello Spyros,

in general when using ajax on your page you can eaily enable/disable any control. Here I prepared a very simplified runnable page demonstrating the approach. When clicking on the second tab there are two buttons for enabling and disabling the tabs of the RadTabStrip control. Of course you can also further extend it to match your requirements.

Sorry for the late reply Kate and thank you for the sample project. This is not exactly my case. My radtabstrip is inside my aspx page so what I want to do is to enable/disable my tabs directly from my usercontrol but... ajax prevents this. I want to know a way to handle the ajax triggering for a control inside a content page from a child control (usercontrol). I dont know if this makes any sense.

Hello Spyros,

I would kindly like to ask you to submit a support ticket where you can attach a simplified version of the project that  you are currently using, so I can help you out in your particular scenario. Thus, I would be able to assist you in the most efficient way.
