Example

The following code shows how to process the GroupDragOver event.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.

Visual Basic

Imports System.Diagnostics
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinExplorerBar

	Private Sub ultraExplorerBar1_GroupDragOver(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinExplorerBar.GroupDragOverEventArgs) Handles ultraExplorerBar1.GroupDragOver

		Dim beforeAfter As String

		If (e.TargetGroupRelativePosition = GroupDropPosition.After) Then
			beforeAfter = "after"
		Else
			beforeAfter = "before"
		End If

		Debug.WriteLine(String.Format("The group '{0}' is being dragged " + beforeAfter + " group '{1}'", e.Group.Text, e.TargetGroup))
		Debug.WriteLine(String.Format("The group is currently over point: ", New Point(e.X, e.Y).ToString()))


		' Don't allow the Group to be dropped if the target group has a key of "System"
		If e.TargetGroup.Key = "System" Then
			e.AllowDrop = False
			e.DragCursor = Cursors.No
		End If

	End Sub

C#

using System.Diagnostics;
using Infragistics.Win;
using Infragistics.Win.UltraWinExplorerBar;

		private void ultraExplorerBar1_GroupDragOver(object sender, Infragistics.Win.UltraWinExplorerBar.GroupDragOverEventArgs e)
		{
			string beforeAfter = (e.TargetGroupRelativePosition == GroupDropPosition.After) ? "after" : "before";

			Debug.WriteLine(string.Format("The group '{0}' is being dragged " + beforeAfter + " group '{1}'", e.Group.Text, e.TargetGroup));
			Debug.WriteLine(string.Format("The group is currently over point: ", new Point(e.X, e.Y).ToString()));


			// Don't allow the Group to be dropped if the target group has a key of "System"
			if (e.TargetGroup.Key == "System")
			{
				e.AllowDrop		= false;
				e.DragCursor	= Cursors.No;
			}
