Ext js grid remove selection model

Question

I have a situation where I need to dynamically add or remove grids selection model.

Searching the documentation I see that the selection model doesn't have a destroy() method or anything similar. How can I remove or destroy a selection model from a grid in ext js 4.x.?

If this is not possible I still have an option to revert some functionallity and dynamically add the selection model to an already created grid. But I'm also not sure if this is possible.

Answer 1

I'd suggest to disable the selection model instead of destroying it.

You can clear the current selection (deselectAll) and lock the selection model to prevent further selection (setLocked):

selModel.deselectAll();
selModel.setLocked(true);

As you're using a checkbox selection model, you'll also need to hide the corresponding column which is added to the grid:

grid.headerCt.child('gridcolumn[isCheckerHd]').hide();
