I want to implement a checkbox column in my tree grid. User can select multiple rows by using keyboard (shift + mouse select) or he can select checkboxes. I am able to write code to check my checkboxes when user uses keyboard or to select row on check of checkbox. but when user uncheck my checkbox, I am not able to remove focus (unselect) from that row, meaning I want to make value of mygrid.getSelectedIds to be null or nothing. How can I do that? Additionaly can I provide functionality of Select All my checkboxes.

You can deselect all by calling:

            grid.clearSelection();

>>Additionaly can I provide functionality of Select All my checkboxes.

            for (i=...

                        grid.cells2(i,check_col_ind).setValue(1);
