ColContaining Method
The ColContaining method returns the ColIndex value of the grid column containing the specified coordinate. This value ranges from 0 to Columns.Count - 1.
object.ColContaining(coordinate)
Arguments
coordinate is a single that defines a horizontal coordinate (X value) in twips.
Return Value
An integer corresponding to the index of the column beneath the specified X coordinate.
This method is useful when working with mouse and drag events when you are trying to determine where the user clicked or dropped another control in terms of a grid column.
If coordinate is outside of the grid's data area, this method returns -1.
The ColContaining method returns the ColIndex of the column indicated, not the visible column position. For example, if coordinate falls within the first visible column, but two columns have been scrolled off the left side of the control, the ColContaining method returns 2, not 0 (assuming that the user did not move any columns previously).
Note
You must convert the coordinate argument to twips, even if the container's ScaleMode (Visual Basic) setting specifies a different unit of measurement.
