FIX: Delay in response for Dispose or Clear methods of a ListView control in Visual Studio .NET 2002

Steps to Reproduce the Behavior

1. Start Microsoft Visual Studio .NET.
2. On the File menu, point to New, and then click Project.
3. Click Visual C# Projects or Visual Basic Projects under Project Types, and then click Windows Application under Templates. By default, Form1 is created.
4. On the View menu, click Toolbox.
5. Drag a ListView control from the toolbox to Form1.
6. Drag a Button control from the toolbox to Form1.
7. Double-click Button1 to view the code.
8. Copy the following code in the button1_Click event handler:
   
   Visual C# .NET Code

   MessageBox.Show("Fill the list");
   listView1.BeginUpdate();
   for(int i=0; i<20000; i++)
   {
       ListViewItem item=new ListViewItem(new string[]{"Hello" , "World" });
       listView1.Items.Add(item);
   }
   listView1.EndUpdate();
   MessageBox.Show("Remove some entries");
   listView1.Items.RemoveAt(1);
   listView1.Items.RemoveAt(2);
   MessageBox.Show("Invoking Clear Method");
   listView1.Clear();
   MessageBox.Show("Clear Method Completed");
   
   MessageBox.Show("Fill the List again");
   
   listView1.BeginUpdate();
   for(int i=0;i<20000;i++)
   {
       ListViewItem item=new ListViewItem(new string[]{"Hello","World"});
       listView1.Items.Add(item);
   }
   listView1.EndUpdate();
   MessageBox.Show("Remove some entries");
   listView1.Items.RemoveAt(1);
   listView1.Items.RemoveAt(2);
   MessageBox.Show("Invoking Dispose Method");
   listView1.Dispose();
   MessageBox.Show("Dispose Method Completed");
   	

   Visual Basic .NET Code

   MessageBox.Show("Fill the list")
   ListView1.BeginUpdate()
   Dim idx As Integer
   For idx = 0 To 20000
       Dim item As ListViewItem = New ListViewItem(New String() {"Hello", "World"})
       ListView1.Items.Add(item)
   Next
   ListView1.EndUpdate()
   MessageBox.Show("Remove some entries")
   ListView1.Items.RemoveAt(1)
   ListView1.Items.RemoveAt(2)
   MessageBox.Show("Invoking Clear Method")
   ListView1.Clear()
   MessageBox.Show("Clear Method completed")
   MessageBox.Show("Re Fill the list")
   ListView1.BeginUpdate()
   Dim idx1 As Integer
   For idx1 = 0 To 20000
        Dim item As ListViewItem = New ListViewItem(New String() {"Hello", "World"})
        ListView1.Items.Add(item)
    Next
    ListView1.EndUpdate()
   
    MessageBox.Show("Remove some entries")
    ListView1.Items.RemoveAt(1)
    ListView1.Items.RemoveAt(2)
   
    MessageBox.Show("Invoking Dispose Method")
    ListView1.Dispose()
    MessageBox.Show("Dispose Method completed")
   

9. On the File menu, click Save.
10. On the Debug menu, click Start to run the project.
