    I working with .net5 version(5.0.20212.112) of the FlexGrid and I'm having trouble dynamically changing the FrozenColumns.

    If the FlexGrid is opened with 0 columns frozen and then change the FrozenColumn to 1 the divider line does not render. If I resize the window, the line displays.

    If the FlexFrid is opened with 1 column frozen, it renders the divider properly and the changing the number works fine.

    Is there a way to refresh the UI so the divider line displays?

    we can reproduce the same issue at our end. However, we will check more on it.
    For meantime, you can use Measure method of the grid like:
    private void Button_Click(object sender, System.Windows.RoutedEventArgs e)

    FrozenColumns += 1;
    grid.FrozenColumns = FrozenColumns;
    grid.FrozenLinesBrush = new SolidColorBrush(Colors.Red);
    grid.Measure(new System.Windows.Size(grid.ActualWidth, grid.ActualHeight));

    Hope, it will solve your issue.

    Thanks. The workaround works. Hopefully it can be resolved natively in later versions.
