I have a WPF User control that binds to a DataTable and generates CheckBox and a masked EditBox for each row in a DataTable. I have several instances of this control on my form. The total number of CheckBoxes to be generated is over 200. I am seeing some rendering performance issues. The form loads with all of the static controls ( Text Boxes, Drop Downs) instantly, then several seconds later the CheckBoxes appear.
Any thoughts?
Thanks
Unless all the 200 items are visible on the screen, you should be using some kind of virtual layout that creates the visual tree only for the visible items. This will greatly improve your performance.
