[CLOSED] Clearing the CheckboxSelectionModel
Hi,
Hope you can help me with following:
Clearing rows from the CheckboxSelectionModel does not seem to work in my scenario.
I use Ext.NET version: 2.2.0.29802
Thanks,
Sander
Hope you can help me with following:
Clearing rows from the CheckboxSelectionModel does not seem to work in my scenario.
- Press button 1. A grid is filled with one item (ID 1), the item is default checked. The Window is Showed.
- Press the Process button. In the DirectEvent is determined how many rows are checked (the MessageBox will display '1').
- Close the Window.
- Press button 2. The grid is filled with a new item (ID 2), the CheckboxSelectionModel is again cleared and the grid item is added.
- Now press the Process button. I would expect that only 1 item is available in the SelectionModel (ID 2). But the SelectionModel contains also the first item (ID 1). How is this possible?
I use Ext.NET version: 2.2.0.29802
Thanks,
Sander
