           Summary: DataGridView hangs on large number of rows (about 500
                    and more)
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.4.x
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Windows.Forms
        AssignedTo: mono-bugs at lists.ximian.com

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; ru; rv:

On table with simple structure: 
  `id` int(11) NOT NULL auto_increment,
  `tt` varchar(255) default NULL,
  `tt2` varchar(255) default NULL,
  `tt3` varchar(255) default NULL,
  PRIMARY KEY  (`id`)

and 1000 rows of records such as:
INSERT into test(tt,tt2)

it takes about minute to render DataGridView. With more complex tables it may
take infinite time (10 minutes and more).
If we replace DataGridView component with DataGrid there is no considerable
delays happens.

Reproducible: Always

Steps to Reproduce:
1. Fill DataTable with necessary data (ex. 1000 rows of complex data).
2. Bind DataGridView to dataTable:
dataGridView.DataSource = dataTable;
3. Wait huge ammount of time while datagrid renders.
Actual Results:  
DataGridView hangs for unpredictable ammount of time (more data -- more time).

Expected Results:  
DataGridView should render 1000 rows in about few seconds.

Test was done on Fedora Core 6 and SUSE Linux
