I am using 4.402.0.51 and there appears to be an issue with setting the LeftColIndex property. The attached project will set the grid's LeftColindex to 2 when Button1 is pressed. To demonstrate the issue, scroll the grid until column B is partially visble on the left side and then press Button1. You will notice that the grid scrolls all the way back to column A instead of the start of B.
