I have a GridView with a SelectColumn (checkboxes). I need to load all the grid in advanced, because the checkbox state controls if the item will be presented or not.
I added an event handler for row loaded which adds an event handler for each row for handling the checked status change.
The problem is when selecting\unselecting the header checkbox. it functions correctly but is very time consuming as it actually loops over all the rows in the grid and handles each row's painting separately.
what i would like to do is to get one event (something like header selected), which will get the information of the items from the data source and will handle the painting once for all rows.
Is that possible? I couldn't find a way for doing it...
