How to avoid my form to freeze (and the whole application) while waiting for the results to populate my table.

Question

My application uses devExpress "Office 2007" tabbed style. When I'm in a form and when I click a button that fills a DevExpress XtraGrid, the whole applicaiton freeze until the results are populated into the table.

How could I allow users to navigate to other "tabs" in my application while waiting for the results ?

Thank you !

:)

You want something like this:

Task.Factory.StartNew(
    () =>
    {
        var object = //Populate your grid

        this.yourXtraGrid.BeginInvoke(new Action(() =>
        {
            this.yourXtraGrid.ItemSource = object ;
        }));
    });

Have you looked into The instant feedback UI?

This is similar to their Async mode in PivotGrid if you are familiar with it.

From my experience you cannot update the grid from another thread.
