Please consider adding a ClientVisible or Display property to panel bar items that we can set server side to control the initial visibility of items on the client.

In the screenshot you can see the PanelBar and a menu to filter items to display. I like what I have except for the fact that I have to run javascript to filter items on each page load and async update based on the selected filter.

RadGrid has a property Display for columns which allows the column to be sent to the client but not be visible initially. I just want something like that for the PanelBar.

Thank you for your consideration.
