By default when setting the ErrorText property the error icon will not appear if the cell is in edit mode. The following sample demonstrates how you can set a cell’s padding in the CellValidating event to provide spacing for the error icon. Since padding by default affects the location of the error icon the sample uses the CellPainting to move the position of the icon for painting.
