I have a weird issue with rad listbox filtering. I tried to attach that, but the post didn't allowed me to. I will write the code here.
The code to populate data is
Now, type something in the list. For example, type "Enabled" so that it filters all enabled columns.
Once filtered , Click on first search result, HOLD down the shift key and Click on the last item in the grid to select ALL values in the listbox.
Click on the right arrow and it should Copy all the selected values to the right grid.
However, you will notice that it copied over Enabled xx as well as Disabled xx which was not in the search result.
That is a problem, I filtered only "Enabled" but it moved "Disabled" as well.
It seems list is hiding the items only, but when you select multiple using SHIFT key, it includes them. Selecting as many items as you can, using one at a time, will not be an issue.
Any thoughts on this should be appreciated.
