Press the control button, hold it there and user can select the rows randomly

Hi everybody

I have attached a screen capture. In the screen capture, the user pressed on the control button from the keyboard, hold it there and selected logical number 2 and 5 at random, may i know is there anyway to disable this function but i would like to retain the function of multi-selecting using the shift button from the keyboard. Thank u very much.

If you want to retain the ability to select more than 1 using shift but not with control, you should probably use the on mouse down event, check if the control key is held and if so, clear what has already been selected and only select the one that has been clicked.

Btw, you didn't attach anything
