Hello all,
This is an extremely frustrating issue. I have a datagrid that is
populated with three different custom datagridtextboxcolumns that I
inherited they all work perfectly, while the code exist! The problem
is that every now and then, when I switch between the design view and
the code view, the instantiating code vanishes. Specifically, the
instantiating code like the following:
Me.RushBoolColumn = new MyRushboolColumn
Me.Master_DataGridTextBoxColumn_1 = new Master_DatagridTextBoxColumn
...etc.
Just disppears! The entry that includes these columnstyles into my
tablestyle disappears with it. All that is left is the defining
classes, and the initial definitions:
Public RushBoolColumn as RushBoolColumn
Public Master_DataGridTextBoxColumn_1 as Master_DatagridTextBoxColumn
etc.
Naturally, I wind up with dozens of build errors, in a program that
was working perfectly before!
After painstakingly putting all of the missing code back in, the
program again runs fine. Until the next time it happens. Sometimes
this happens 2-3 times a day. Sometimes it doesn't happen at all. I
can't find a pattern, except that it seems to happen when I switch
between views and it seems to happen more often when I check the
datagrid properties window.
I am using Visual Basic 2002. I have never had these problems before,
though I have also never used a datagrid before. Can anyone help?
thank you,
Mike Cooper
