In my Laszlo application I have a list view and a grid view. The
selection in the list view controls what is displayed in the grid view.
When a user selects an item in the list, I automatically formulate a
request to update the datasource of the grid. Depending on the amount of
data retrieved, this process can take a few seconds. Right now there is
no feedback to the user that anything is going on and the interface
appears to be hung. Has anyone else dealt with this problem and if so
what sort of solution did you come up with?
One simple idea I had was to simply blank the grid view until the response
was returned, but I'm not sure how to go about doing that. Another idea
would be to pop up an animated progress bar, but I have even less of a
clue how I might do that. If others have addressed this sort of problem
and have examples they wish to share, I would appreciate it.
Thanks!
