hi,
having a really strange problem...not seen this problem before..and ive used winultra grids for awhile now. I have a main form set with a ultragrid displayed on it...when i call a dataset from a storeprocedure and ask the datagridview to display the data, it works perfect. However...when i click the scroll button to scroll down the data...it crashes my application with the following exception:
Cross-thread operation not valid: Control 'ultragridview1' accessed from a thread other than the thread it was created on.
any ideas?this is happening on all my applications im working on using ultragrids.
thanks
EDIT: since googling the error..its apprently a threading problem..this code is not using threading
You should make sure you have the latest Hot Fix and if that doesn't help, Submit an incident to Infragistics Developer Support so they can check this out.
I'm have seen the same thing. It happens when running the application under Visual Studio in Debug mode.
I can duplicate it by simply filling a grid with 1000 rows of dummy data and holding the mouse button down on the scroll arrow. You can click the scroll arrow without issue, unless you do it very rapidly.
hi mike, yeah..its occuring on every application im using now...which involves ultrawingrid..i'll try a reinstall of infragistics.
This definitely appears to be a threading issue. Are you sure your code is not using multiple threads?
Also, are you using the UltraWinGrid here? You mentioned the DataGridView, which is not the same control.
If this is, in fact, an UltraWinGrid, and you are certain that your application is not using multiple threads, then your best bet is to try to reproduce the issue in a small sample project and Submit an incident to Infragistics Developer Support so they can check it out.
