event MouseDown (Button as Integer, Shift as Integer, X as OLE_XPOS_PIXELS, Y as OLE_YPOS_PIXELS)
Occurs when the user presses a mouse button.

TypeDescription
Button as Integer An integer that identifies the button that was pressed to cause the event
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 value 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 value 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 NodeFromPoint method to get the node from cursor.

The following VB sample displays the node being clicked:

Private Sub XMLGrid1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    With XMLGrid1
        Dim n As EXMLGRIDLibCtl.Node
        Set n = .NodeFromPoint(X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY)
        If Not n Is Nothing Then
            Debug.Print "You have clicked the '" & n.Name & "'."
        End If
    End With
End Sub

The following C++ sample displays the node being clicked:

#include "Node.h"
void OnMouseDownXmlgrid1(short Button, short Shift, long X, long Y) 
{
	CNode node = m_xmlgrid.GetNodeFromPoint( X, Y );
	if ( node.m_lpDispatch != NULL )
	{
		CString strName = node.GetName();
		OutputDebugString( strName );
	}
}

The following VB.NET sample displays the node being clicked:

Private Sub AxXMLGrid1_MouseDownEvent(ByVal sender As Object, ByVal e As AxEXMLGRIDLib._IXMLGridEvents_MouseDownEvent) Handles AxXMLGrid1.MouseDownEvent
    With AxXMLGrid1
        Dim n As EXMLGRIDLib.Node = .get_NodeFromPoint(e.x, e.y)
        If Not n Is Nothing Then
            Debug.Print("You have clicked the '" & n.Name & "'.")
        End If
    End With
End Sub

The following C# sample displays the node being clicked:

private void axXMLGrid1_MouseDownEvent(object sender, AxEXMLGRIDLib._IXMLGridEvents_MouseDownEvent e)
{
	EXMLGRIDLib.Node node = axXMLGrid1.get_NodeFromPoint(e.x, e.y);
	if (node != null)
		System.Diagnostics.Debug.Write(node.Name);
}

The following VFP sample displays the node being clicked:

*** ActiveX Control Event ***

with thisform.XMLGrid1
	n = .NodeFromPoint(x, y )
	if ( !isnull(n) )
