    Event raised on different thread problem

    Hi,

    I have a dataset object that is binded to a datagrid in my main
    thread. Now, when I add a row to the dataset object in a another
    thread (since it may take awhile to complete), sometimes my
    application will crash. I suspect this is because the ListChanged
    event is raised on a different thread to the thread that my dataset
    object was bound to the datagrid. My question is, how do I get around
    this problem? I would think this would be a common problem, but
    haven't found any answers.

    Thanks in advance.

      The answer is to add the row on the proper thread. Use dataGrid.Invoke .
