DataGridView RowEnter not firing...

Using VS2005, VB.NET,
I have a windows app with a DataGridView (lets call it DGV). At some
point in the life of my app I want to clear the selection of the
currently selected row (Multiselect=false) from DGV - to do that I
tried this:
DGV.ClearSelection()

Cosmetically this appears to work but it appears that the DGV still
stores the index value of the selected row. If the 1st row I click on
after executing ClearSelection() is the row that was previously
selected then the RowEnter event is NOT triggered - clicking on any
other row than the previously selected row DOES trigger the RowEnter
event.

Is this a bug and/or is there some (other) way for me to clear the
selection of current row from a DGV?

Any help would be appreciated...
 
If you have a datatable underlying the datagridview then you need to
manipulate the row in the underlying datatable

My DataGridView's DataSource is an in memory DataTable. Regardless it
is the DataGridView control that is not responding to a click on a row
that was selected just prior to calling the DataGridView's
ClearSelection() method - it seems that this would be independent of
any underlying data....

Rich,
I mis-read your message - please ignore my previous response.

Ok, so I changed the code to be this:

Me.dgvCases.CurrentRow.Selected = False
Me.dgvCases.ClearSelection()

But the problem persists. After this code runs - no rows in the DGV
are highlighted but the DGV's record selector (little triange) still
points to the previously selected row & I get the same result as
before.

Is there another setting in the "row in the underlying datatable" that
I need to manipulate?

I finally figured this out... instead of setting the CurrentRow to not
be selected, I set CurrentCell=Nothing to get the behavior I was
looking for. I no longer needed to call ClearSelection() call. Here's
the code that worked for me:

Me.dgvCases.CurrentCell = Nothing

Thanks to those that responded.

I have been struggling with this same issue, and have discovered that
setting CurrentCell = Nothing does not prevent a row from being
selected if it is done before the first Paint event. It appears that
the DataGridView selects the first row when it is first painted.

Yea, I've read similar things. Fortunately for me, my call to set the
DataGridView's CurrentCell = Nothing is long after the control is
initially painted so I did not run into this issue. Best of luck and
thanks again for your help.
