Occurs when the user releases a mouse button.
Type | Description | |||
Button as Integer | An integer that identifies the button that was pressed to cause the event as as 1 for Left Mouse Button, 2 for Right Mouse Button and 4 for Middle Mouse Button. | |||
Shift as Integer | An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys when the button specified in the button argument is pressed or released. | |||
X as OLE_XPOS_PIXELS | A single that specifies the current X location of the mouse pointer. The x values is always expressed in container coordinates. | |||
Y as OLE_YPOS_PIXELS | A single that specifies the current Y location of the mouse pointer. The y values is always expressed in container coordinates. |
Use a MouseDown or MouseUp event procedure to specify actions that will occur when a mouse button is pressed or released. Unlike the Click and DblClick events, MouseDown and MouseUp events lets you distinguish between the left, right, and middle mouse buttons. You can also write code for mouse-keyboard combinations that use the SHIFT, CTRL, and ALT keyboard modifiers. Use the ItemFromPoint property to get the item from point. Use the ColumnFromPoint property to get the column from point. Use the DateFromPoint property to specify the date from the cursor. The NoteFromPoint property retrieves the note/box from the cursor. Use the AnchorFromPoint property to retrieve the identifier of the anchor element from the cursor. Almost all properties that get an object from point supports -1,-1 coordinate that specifies the current cursor position, so no conversion is required for X and Y coordinates.
Syntax for MouseUp event, /NET version, on:
private void MouseUpEvent(object sender,short Button,short Shift,int X,int Y) { } Private Sub MouseUpEvent(ByVal sender As System.Object,ByVal Button As Short,ByVal Shift As Short,ByVal X As Integer,ByVal Y As Integer) Handles MouseUpEvent End Sub |

The following Access sample prints the cell's caption where the mouse has been released:
Private Sub G2antt1_MouseUp(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Long, ByVal Y As Long) Dim h As HITEM Dim c As Long, hit As Long h = G2antt1.ItemFromPoint(-1, -1, c, hit) If Not (h = 0) Then MsgBox "The """ & G2antt1.Items.CellValue(h, c) & """ cell has been double clicked." End If End Sub
The following VB sample prints the cell's caption where the mouse has been released:
Private Sub G2antt1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single) ' Converts the container coordinates to client coordinates X = X / Screen.TwipsPerPixelX Y = Y / Screen.TwipsPerPixelY Dim h As HITEM Dim c As Long, hit as Long ' Gets the item from (X,Y) h = G2antt1.ItemFromPoint(X, Y, c, hit) If Not (h = 0) Then Debug.Print G2antt1.Items.CellValue(h, c) End If End Sub
If you need to add a context menu based on the item you can use the MouseUp event, like in the following VB sample ( the sample uses the Exontrol's ExPopupMenu Component ):
Private Sub G2antt1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single) If (Button = 2) Then ' Converts the container coordinates to client coordinates X = X / Screen.TwipsPerPixelX Y = Y / Screen.TwipsPerPixelY Dim h As HITEM Dim c As Long, hit as Long ' Gets the item from (X,Y) h = G2antt1.ItemFromPoint(X, Y, c, hit) If Not (h = 0) Then Dim i As Long PopupMenu1.Items.Add G2antt1.Items.CellValue(h, c) i = PopupMenu1.ShowAtCursor End If End If End Sub
The following VC sample displays the caption of the cell where the mouse is released:
#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 OnMouseUpG2antt1(short Button, short Shift, long X, long Y) { long c = 0, hit = 0, hItem = m_g2antt.GetItemFromPoint( X, Y, &c, &hit ); if ( ( hItem != 0 ) || ( c != 0 ) ) { CItems items = m_g2antt.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 caption of the cell where the mouse is released:
Private Sub AxG2antt1_MouseUpEvent(ByVal sender As Object, ByVal e As AxEXG2ANTTLib._IG2anttEvents_MouseUpEvent) Handles AxG2antt1.MouseUpEvent With AxG2antt1 Dim i As Integer, c As Integer, hit As EXG2ANTTLib.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 caption of the cell where the mouse is released:
private void axG2antt1_MouseUpEvent(object sender, AxEXG2ANTTLib._IG2anttEvents_MouseUpEvent e) { int c = 0; EXG2ANTTLib.HitTestInfoEnum hit; int i = axG2antt1.get_ItemFromPoint( e.x, e.y, out c,out hit ); if ( ( i != 0 ) || ( c != 0 ) ) { string s = axG2antt1.Items.get_CellValue( i,c ).ToString(); s = "Cell: " + s + ", Hit: " + hit.ToString(); System.Diagnostics.Debug.WriteLine( s ); } }
The following VFP sample displays the caption of the cell where the mouse is released:
