RadPanelBar - desible collapsing?

[Ljubo Žižić]

Is there any way to disable collapsing of RadPanelBar - GroupStyle ListBar?
Because, I want to disable collapsing of exact group element until some action has done. After that, all elements should collapse normally.

Best regards,

Hello Ljubo Žižić,

You can achieve this by using the PanelBarGroupExpanding event. The event is fired when a group is expanding.

Test Example:

1. I have added three different groups with captions "Default Caption", "Caption" and "DefaultCaption"
2. I subscribed to PanelBarExpanding event of RadPanelBar
3. In the event handler, I canceled the expansion of a group with caption different than "Caption". "Caption" is the caption of the group which I want to disable to collapse.

 void radPanelBar1_PanelBarGroupExpanding(object sender, PanelBarGroupCancelEventArgs args)
        {
            if (args.Group.Caption != "Caption")
            {
                args.Cancel = true;
            }
        }

In the above code I cancel the expanding of all groups with Captions different than "Caption". I hope this helps.

Kind regards,
