event RClick ()
Fired when right mouse button is clicked

TypeDescription
Use the RClick event to add your context menu. The RClick event notifies your application when the user right clicks the control. Use the Click event to notify your application that the user clicks the control ( using the left mouse button ). Use the MouseDown or MouseUp event if you require the cursor position during the RClick event. Use the RClickSelect property to specify whether the user can select items by right clicking the mouse. Use the ItemFromPoint property to get the item from point. Use the ColumnFromPoint property to get the column from point.

The following VB sample use Exontrol's ExPopupMenu Component to display a context menu when user has clicked the right mouse button in the control's client area:

Private Sub Grid1_RClick()
    Dim i As Long
    i = PopupMenu1.ShowAtCursor
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:

Private Sub Grid1_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 = Grid1.ItemFromPoint(X, Y, c, hit)
        If Not (h = 0) Then
            Dim i As Long
            PopupMenu1.Items.Add Grid1.Items.CellCaption(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 OnMouseUpGrid1(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 caption of the cell where the mouse is released:

Private Sub AxGrid1_MouseUpEvent(ByVal sender As Object, ByVal e As AxEXGRIDLib._IGridEvents_MouseUpEvent) Handles AxGrid1.MouseUpEvent
    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.CellCaption(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 axGrid1_MouseUpEvent(object sender, AxEXGRIDLib._IGridEvents_MouseUpEvent 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 ) )
	{
		string s = axGrid1.Items.get_CellCaption( 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:

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