The MouseMove event is generated continually as the mouse pointer moves across objects. Unless another object has captured the mouse, an object recognizes a MouseMove event whenever the mouse position is within its borders. Use the ItemFromPoint property to get the item from cursor. Use the ColumnFromPoint property to get the column from point. The Background(exCursorHoverColumn) property specifies the visual appearance of the column's header when the cursor hovers it. Use the AnchorFromPoint property to retrieve the identifier of the anchor element from the point.

The following VB sample prints the cell's caption from the cursor ( if the control contains no inner cells. Use the SplitCell property to insert inner cells ) :

Private Sub Grid1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    On Error Resume Next
    ' Converts the container coordinates to client coordinates
    X = X / Screen.TwipsPerPixelX
    Y = Y / Screen.TwipsPerPixelY
    Dim h As HITEM
    Dim c As Long
    Dim hit As EXGRIDLibCtl.HitTestInfoEnum
    ' Gets the item from (X,Y)
    h = Grid1.ItemFromPoint(X, Y, c, hit)
    If Not (h = 0) Then
        Debug.Print Grid1.Items.CellValue(h, c) & " HT = " & hit
    End If
End Sub

The following VB sample displays the cell's caption from the cursor ( if the control contains inner cells ):

Private Sub Grid1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    On Error Resume Next
    ' Converts the container coordinates to client coordinates
    X = X / Screen.TwipsPerPixelX
    Y = Y / Screen.TwipsPerPixelY
    Dim h As HITEM
    Dim c As Long
    Dim hit As EXGRIDLibCtl.HitTestInfoEnum
    ' Gets the item from (X,Y)
    h = Grid1.ItemFromPoint(X, Y, c, hit)
    If Not (h = 0) Or Not (c = 0) Then
        Debug.Print Grid1.Items.CellValue(h, c) & " HT = " & hit
    End If
End Sub

The following C++ sample displays the cell's from the point:

#include "Items.h"

static CString V2S( VARIANT* pv, LPCTSTR szDefault = _T("") )
{
	if ( pv )
	{
		if ( pv->vt == VT_ERROR )
			return szDefault;

		COleVariant vt;
		vt.ChangeType( VT_BSTR, pv );
		return V_BSTR( &vt );
	}
	return szDefault;
}

void OnMouseMoveGrid1(short Button, short Shift, long X, long Y) 
{
	long c = 0, hit = 0, hItem = m_grid.GetItemFromPoint( X, Y, &c, &hit );
	if ( ( hItem != 0 ) || ( c != 0 ) )
	{
		CItems items = m_grid.GetItems();
		COleVariant vtItem( hItem ), vtColumn( c );
		CString strCaption = V2S( &items.GetCellValue( vtItem, vtColumn ) ), strOutput;
		strOutput.Format( "Cell: '%s', Hit = %08X\n", strCaption, hit );
		OutputDebugString( strOutput );
	}
}

The following VB.NET sample displays the cell's from the point:

Private Sub AxGrid1_MouseMoveEvent(ByVal sender As Object, ByVal e As AxEXGRIDLib._IGridEvents_MouseMoveEvent) Handles AxGrid1.MouseMoveEvent
    With AxGrid1
        Dim i As Integer, c As Integer, hit As EXGRIDLib.HitTestInfoEnum
        i = .get_ItemFromPoint(e.x, e.y, c, hit)
        If (Not (i = 0) Or Not (c = 0)) Then
            Debug.WriteLine("Cell: " & .Items.CellValue(i, c) & " Hit: " & hit.ToString())
        End If
    End With
End Sub

The following C# sample displays the cell's from the point:

private void axGrid1_MouseMoveEvent(object sender, AxEXGRIDLib._IGridEvents_MouseMoveEvent e)
{
	int c = 0;
	EXGRIDLib.HitTestInfoEnum hit;
	int i = axGrid1.get_ItemFromPoint( e.x, e.y, out c,out hit );
	if ( ( i != 0 ) || ( c != 0 ) )
	{
		object cap = axGrid1.Items.get_CellValue(i, c);
		string s = cap != null ? cap.ToString() : "";
		s = "Cell: " + s + ", Hit: " + hit.ToString();
		System.Diagnostics.Debug.WriteLine(s);
	}
}

The following VFP sample displays the cell's from the point:

*** ActiveX Control Event ***

local c, hit
c = 0

	.Items.DefaultItem = .ItemFromPoint( x, y, @c, @hit )
