[CLOSED] GridPanel SelectionModel
Hello,
Perhaps you can help me out with the following 2 problems I'm encountering:
1. The CheckboxSelectionModel.SelectedID / SelectedIndex does not appear to be working i nthe example below.
2. When I select a record using the CheckboxSelectionModel and switch my view by hitting "Switch to View 2" and switch back by clicking "Switch to View 1" my selection is lost in the postback.
