locking first column to be non-resizable

I want to lock the first column of my grid.I know the split feature.But i am not looking for that.I just want the first column to not be resizable…Meaning if we try to resize my using the mouse on the column header it should not allow the resizing.

grid component allows to configure , which columns can be resized and which not


parameter of function - list of flags for each column, true - allow resizing, false - deny resizing
