[CLOSED] GridPanel inside TabPanel - any alternative to DeferredRender="false" to get Grid to render?
Hi,
If I have a simple array grid in an inactive tab, when that tab is activated, the grid renders okay, except its pager is empty (not initialized correctly).
I find that on the containing TabPanel, I have to set DeferredRender="false". While this works, I suppose if you have a TabPanel with lots of items in it it might be a bit inefficient as I think it renders ALL items.
Just wanted to ask if there is an alternative I may have missed?
Here is a working example (add DeferredRender="false" to the TabPanel for the paging on the GridPanel to work)
