An application sends a ZGM_GETDISPLAYPOSITIONOFCOLUMN message to get the dislay positon of the specified column in the ZeeGrid. Since the user can reorder the display positions of the columns, this message provides a way to programmatically determine the display position of a particular column.
ZGM_GETDISPLAYPOSITIONOFCOLUMN
wParam = (WPARAM)(int) iColumn; //column number
lParam = 0; //not used; must be zero
The display position of the specified column is returned.
