Looping thru checkbox

[Gandalf23]

I have a Grid which has a DataView bound to it. The first column is a CheckBoxColumn. When a user RightClicks the grid a contextmenu shows up [Check, Uncheck].

If a user clicks on Check, all the CheckBoxColumn are being checked. But the cell which is selected on that moment isn't. I looked if it is a refresh problem, it's not. Any ideas?

Greetings,

Gandalf.

Code:

private void VinkjesAanUit(Boolean bAan)
{
  if (this.dsExport != null)
  {   			
    for (int i=0; i <this.dsExport.Tables&quot;Besluit&quot;].Rows.Count;i++)
    {
	this.dsExport.Tables[&quot;Besluit&quot;].Rows[i][&quot;Export&quot;] = bAan;
    }
  }
}
