This is another thing I came on today.

I use DevExpres grid and BusinessBindingSource to edit a BO. DevExpress grid has an empty row, that is used for inserting new rows in the grid. When trying to insert a new row, I click on the grid's empty row and type something in. The first character I type is always lost. Then the cell leaves edit mode, and then I type again and everything works fine. But the first character is always lost. For instance if I try to type "George" the actuall thing that the cell will contain is "eorge". And this only happens when I set default values on the BO_SetDefaultValues event handler. If the handler is empty, all work fine.

My SetDefaultValues handler is:

private void ContactBO_SetDefaultValues()
{
  this.ContactID = Guid.NewGuid();
  this.ContactType = 3;
}

But, when I make a BeginEdit in the current row:

private void ContactBO_SetDefaultValues()
{
  this.CurrentRow.BeginEdit();
  this.ContactID = Guid.NewGuid();
  this.ContactType = 3;
}

then all work fine when inserting new row in a grid which has some rows already. When I try to insert a new row in a grid with no rows at all, the same thing still happens. The first character I type is lost.

I have tried to set default values, on the OnAfterAddNew, OnBeforeAddNew, OnEditingStateChanged events, nut still the same thing happens.

Has anyone seen that before?
