Silverlight ScrollViewer takes focus when scrollbars are not visible

I'm finding that Silverlight's ScrollViewer will still take focus even when the scrollbars are not visible.

Has anyone else seen this issue? Are there any workar开发者_JAVA百科ounds that will prevent the ScrollViewer acting as a tabstop when the scrollbars are invisible?

Thanks,

What about:

<ScrollViewer IsTabStop="False" ...

There is a simple solution, at least in Silverilght 4 and up. Listen to the LayoutUpdated event on the ScrollViewer and set the IsTabStop property based on the status of the scrollbars.

For example, if you only are using a vertical scroll bar:

void myScrollViewer_LayoutUpdated(object sender, EventArgs e)
{
    //this should only be a tabstop if the scrollbar is visible.
    myScrollViewer.IsTabStop = 
       (myScrollViewer.ComputedVerticalScrollBarVisibility == Visibility.Visible);
}
