I have page with a weblistbox realtime creation.
Before launch a new query I’m closing the weblistbox.
After launch the query and remove/draw the weblistbox (more or less 3 or 4 times), the grid is filled like a blank rectangle (with the menu) but it’s completely empty.
After this, if I run the query again the weblistbox is allways empty
Can someone help me?
I’m managing all exceptions but there is no exception
