Preserve existing selections on row click for CheckboxSelectionModel in grid
I am using CheckboxSelectionModel. After selecting some rows, clicking some other cell / row on the grid causes previously selected rows to be unselected.I know there is a checkOnly config option is available but that is only in in ExtJs 3.x versions. Can anyone please let me know how can I achieve this in ExtJs 2.x version ? \
I referred to checkOnly property's source code and found below code, will it work, please suggest.
Thanks in advance.
Setting handleMouseDown event handler to empty function as below worked for me
gridSelectionModel.handleMouseDown = Ext.emptyFn;
