[Solved] how to prevent the panel bar from collapsing/ always keep as expanded

Hi telerik team,

I am using a panel bar in my code and wish to have it expanded on load and always and prevent it from collapsing when clicked at header, any thoughts please ?

Hello Narayanarao,


Generally speaking to achieve this you should:

1. Initially expand each of the panels. You can use the ItemAction method
   .ItemAction(item=>item.Expanded=true)
2. Subscribe a function to the OnCollapse event and call the preventDefault() method exposed by the argument parameter.

Well I just tried your suggestion, it fixes the collapse problem. But then it is breaking the telerik combobox ! It prevents the telerik combo box from expanding. i.e. i click at the combobox arrow nothing happens . I just remove the "

.ClientEvents(events => events.OnCollapse("preventCollapseOfPanel()"))"

and it works good. the script is as below

function preventCollapseOfPanel(e){
                    e.preventDefault();
                    }
please suggest .
Thanks,
Anand

Hello again Narayanarao,

When you declare the function handling the event you need to pass only the name of the function without the brackets.
i.e.

.ClientEvents(events => events.OnCollapse("preventCollapseOfPanel"))
