Hello,
I am using the show/hide columns option of HeaderContextMenu (RadGrid).
It works very well.
But at each time the rebind() is executed, the radgrid doesn't remember the columns which are hided or shown.
Is there a way after each postback, to remember the hided/shown columns.

I've tried to handle the event:

aRadGrid.HeaderContextMenu.ItemCreated +=

new RadMenuEventHandler(HeaderContextMenu_ItemCreated);
but it doesn't fire.

 

I manage the radgrid programmatically...
aRadGrid.MasterTableView.EnableHeaderContextMenu =

true;

Regards

Sorry,

It's the event :

aRadGrid.HeaderContextMenu.ItemClick += new RadMenuEventHandler(HeaderContextMenu_ItemClick);

which doesn't fire !

Hello Bernard,

Please try adding the event handler in  Page_Init.
C#:

protected void Page_Init()
{
       ...
  aRadGrid.HeaderContextMenu.ItemCreated += new RadMenuEventHandler(HeaderContextMenu_ItemCreated);
       ...
}

Thanks,
Shinu.

Hi Shinu,
Thanks for your answer...
Actually, the event aRadGrid.HeaderContextMenu.ItemCreated += newRadMenuEventHandler(HeaderContextMenu_ItemCreated); is fired in load method.
But I've tried as you recommanded :

protected void Page_Init()

{

...
aRadGrid.HeaderContextMenu.ItemCreated += new RadMenuEventHandler(HeaderContextMenu_ItemCreated);
aRadGrid.HeaderContextMenu.ItemClick += new RadMenuEventHandler(HeaderContextMenu_ItemClick);
...
}

the event aRadGrid.HeaderContextMenu.ItemCreated += newRadMenuEventHandler(HeaderContextMenu_ItemCreated); is fired.
But the event aRadGrid.HeaderContextMenu.ItemClick += new RadMenuEventHandler(HeaderContextMenu_ItemClick);  is not fired
