Use the UserEditorClose event to notify your application when the user editor is hidden. Use the UserEditorClose event to update the cell's value when user editor is hidden. The control fires UserEditorOleEvent event each time when a an user editor object fires an event.

private void UserEditorClose(object sender,object Obj,int Item,int ColIndex)
{
}

Private Sub UserEditorClose(ByVal sender As System.Object,ByVal Obj As Object,ByVal Item As Integer,ByVal ColIndex As Integer) Handles UserEditorClose

The following VB sample updates the cell's value when the user editor is hidden ( the sample handles the event for an exMaskEdit inside ):

Private Sub G2antt1_UserEditorClose(ByVal Object As Object, ByVal Item As EXG2ANTTLibCtl.HITEM, ByVal ColIndex As Long)
    With G2antt1.Items
        .CellValue(Item, ColIndex) = Object.Text
    End With
End Sub

The following C++ sample updates the cell's value when the user editor is hidden ( the sample handles the event for an exMaskEdit inside ):

#import <maskedit.dll>

#include "Items.h"

void OnUserEditorCloseG2antt1(LPDISPATCH Object, long Item, long ColIndex) 
{
	MaskEditLib::IMaskEditPtr spMaskEdit( Object );
	if ( spMaskEdit != NULL )
	{
		COleVariant vtNewValue(spMaskEdit->GetText());
		m_g2antt.GetItems().SetCellValue( COleVariant( Item ), COleVariant( ColIndex ), vtNewValue );
	}
}

where the #import <maskedit.dll> defines the type library of the exMaskEdit component, in the MaskEditLib namespace.  The V2S function converts a VARIANT value to a string value and may look like follows:

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;
}

The following VB.NET sample updates the cell's value when the user editor is hidden ( the sample handles the event for an exMaskEdit inside ):

Private Sub AxG2antt1_UserEditorClose(ByVal sender As Object, ByVal e As AxEXG2ANTTLib._IG2anttEvents_UserEditorCloseEvent) Handles AxG2antt1.UserEditorClose
    With AxG2antt1.Items
        .CellValue(e.item, e.colIndex) = e.object.Text
    End With
End Sub

The following C# sample updates the cell's value when the user editor is hidden ( the sample handles the event for an exMaskEdit inside ):

private void axG2antt1_UserEditorClose(object sender, AxEXG2ANTTLib._IG2anttEvents_UserEditorCloseEvent e)
{
	MaskEditLib.MaskEdit maskEdit = e.@object as MaskEditLib.MaskEdit;
	if (maskEdit != null)
		axG2antt1.Items.set_CellValue(e.item, e.colIndex, maskEdit.Text);
}

where the MaskEditLib class is defined by adding a new reference to the ExMaskEdit component to your project.

The following VFP sample updates the cell's value when the user editor is hidden ( the sample handles the event for an exMaskEdit inside ):
