RadPanelBar, ViewState off and PostBack problem

[Chen]

Hi
My app has ViewState disabled.
I have a panel bar with multiple items. Depending on some server side logic, I may hide some panel items.
The PanelBar loads fine.
However, on postback the wrong panel item opens.
Let's say I have 5 panel items and the server side logic hides the first one.
If I click Edit on the 4th item, on postback the 3rd item would open.

In the example below, no panel would be open on postback.
How can I fix it?

Thanks
Chen

Code behind:

protected void Page_Load(object sender, EventArgs e)
{
       RadPanelBar1.Items[0].Visible = RadPanelBar1.Items[0].Enabled =false;
}

Hi Chen,

We have already responded to your support ticket regarding this issue.

Really Telerik? 

Saying, "we already responded" and not providing a link to your reply doesn't help others who find this page with a similar problem.

Come on guys, you're better than this.

Hi Spencer,

Since the response was in a support ticket there is no way that we can provide its url. However, below you can find the answer of the ticket along with a runnable page:

In general when the ViewState is disabled, it's your responsibility to restore the state of the page after a post-back. You can find the attached example page where the expanded items are saved into a hidden field on the page and when a post-back occur in Page_Load event these items are expanded again manually. This should prevent problems with the wrong expanded items even, if you hide/remove some of them.

Kind regards,
Kate
