CheckedListBox not behaving normally

[tina33]

Hi There

I have a form with 2 Tabs. Each one of the Tabs has got a multicolumn checkedlistbox control.

The controls are drawn on the screen at run time using values from 2 views of the same table.

The following is part of the code I use to draw my controls:

Me.chkListBox1.DataSource = dvMyDataView  'the table view
Me.chkListBox1.DisplayMember = "Display_Description"  'column Name to display on control
Me.chkListBox1.ValueMember = "Checked"   'column name to store checkstate

The idea is to assign the checkstate to the column named "Checked" each time I click a box on the control.

My controls are drawn on the screen and I can check/uncheck my boxes. However, on leaving the current Tab go to the next one, I realise that my checkbox is cleared and becomes blank.

Any ideas as to why this is happening?

Your help will be appreciated.

Thanks
