I have a Select All checkbox on top of ListGrid.
Initially there is no group by applied on the ListGrid.
So when the Select All checkbox is checked all the records are selected.
Now I group by "name" field.
There are two groups GROUP1 & GROUP2
When I try to uncheck the Select All checkbox ,the records in the groups are not unchecked.(still they are in checked state)
Following is code.
