I'm working with vb.net 2005.

I have a class that i've loaded up with my data. Then created a datasource
off the class. I load up the datagridview with data from a class.. all this
is working fine. I've got data.

My problem is with the tag on the datagridview. I've gone in and bound it to
the column in the datasource taht I want (i've done it like this before)

when i create the double click event on the datagridview, in other code i've
been able to do a datagridview.tag and get the value of column and row that
i've double clicked on. I can't figure it out why it's giving me a value =
nothing instead.

there must be something that I'm forgetting because like I said.. i've done
this before...

hopefully someone can help.
Here is what I'm doing to load up the datagridview with data...

With oBuildingUtils
           .LoadFromDB()
       End With

       With oBuildings
           oBuildings = oBuildingUtils.Load("")
       End With        Me.BuildingDataGridView.DataSource = oBuildings

Like i mention above.. this part is working.. just not when i double click
on the datagridview.
thanks
