If you are using data binding with your controls that are part of the dockable bars that can be placed in floating mode you might need to update the BindingContext on the floating bar’s form so functionality that relies on updating the common BindingContext like for example DataGridView sorting propagated through multiple grids, can work as expected.

To do that you need to handle DotNetBarManager.BarUndock event and have following code there:

C#:

private void dotNetBarManager1_BarUndock(object sender, EventArgs e)
{
    Bar bar = sender as Bar;
    if (bar != null)
    {
        Form f = bar.FindForm();
        if (f != this)
            f.BindingContext = this.BindingContext;
    }
}
