I loaded an excel file into the grid. It imported empty columns along with some data columns. I used the RemoveCols Method to remove these emplty columns. But it doesn't seem to work. The colCount still remains the same. I tried Refresh and Repaint after the RemoveCols methods, but nothing is working, Any suggestions?
I can't reproduce a problem with RemoveCols() here. What exact parameters do you use for this method?
