DataGrid ScrollBar problem

[Francois Tremblay]

Hi, Actually i'm developping an application for ppc 2003. The problem
is that i'm adding data (new line) to a grid, when adding a new line
to the grid an event is probably sent to the grid and the scrollbar
appears (when too much line in the grid), but when the scrollbar
appears everything freeze (at this time the debugger in visual studio
2003 stops working like if was lost) ???? Does anyone can help
me???????

Most likely that's because you're adding data from another thread (which
would result in updating UI from another thread).
You should use Control.Invoke to add data.

Please see this for more details:

Hi Ilya, thanks for your answer! My application uses a serial
communication with a bluetooth scanner. I used the Me.Invoke to
display the data in the grid and now it works fine.
