Use the ColumnFromPoint property to access the column from the point specified by the {X,Y} coordinates. The ColumnFromPoint property gets the index of the column when the cursor hovers the control's header bar. The X and Y coordinates are expressed in client coordinates, so a conversion must be done in case your coordinates are relative to the screen or to other window. If the X parameter is -1 and Y parameter is -1 the ColumnFromPoint property determines the index of the column from the cursor. Use the ItemFromPoint property to retrieve the item from cursor. Use the DateFromPoint property to specify the date from the cursor. The control fires the ColumnClick event when user clicks a column.  Use the SortOnClick property to specify the operation that control odes when user clicks the control's header. Use the BarFromPoint property to get the bar from the point. Use the LinkFromPoint property to get the link from the point. Use the LevelFromPoint property to retrieve the index of the level from the cursor.

The following VB sample prints the caption of the column from the point:

Private Sub G2antt1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    With G2antt1
        Dim c As Long
        c = .ColumnFromPoint(X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY)
        If (c >= 0) Then
            With .Columns(c)
                Debug.Print .Caption
            End With
        End If
    End With
End Sub

The following C++ sample prints the caption of the column from the point:

#include "Columns.h"
#include "Column.h"
void OnMouseMoveG2antt1(short Button, short Shift, long X, long Y) 
{
	long nColIndex = m_g2antt.GetColumnFromPoint( X, Y );
	if ( nColIndex >= 0 )
	{
		CColumn column = m_g2antt.GetColumns().GetItem( COleVariant( nColIndex ) );
		OutputDebugString( column.GetCaption() );
	}
}

The following VB.NET sample prints the caption of the column from the point:

Private Sub AxG2antt1_MouseMoveEvent(ByVal sender As Object, ByVal e As AxEXG2ANTTLib._IG2anttEvents_MouseMoveEvent) Handles AxG2antt1.MouseMoveEvent
    With AxG2antt1
        Dim i As Integer = .get_ColumnFromPoint(e.x, e.y)
        If (i >= 0) Then
            With .Columns(i)
                Debug.WriteLine(.Caption)
            End With
        End If
    End With
End Sub

The following C# sample prints the caption of the column from the point:

private void axG2antt1_MouseMoveEvent(object sender, AxEXG2ANTTLib._IG2anttEvents_MouseMoveEvent e)
{
	int i = axG2antt1.get_ColumnFromPoint( e.x,e.y );
	if ( i >= 0 )
		System.Diagnostics.Debug.WriteLine( axG2antt1.Columns[i].Caption  );
}

The following VFP sample prints the caption of the column from the point:

*** ActiveX Control Event ***
LPARAMETERS button, shift, x, y

with thisform.G2antt1
	i = .ColumnFromPoint( x, y )
	if ( i >= 0 )
		wait window nowait .Columns(i).Caption
