ultragrid crashing when scrolling
posted

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

    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.
