Depending on where your errors are occurring you can do something like...

public abstract class SilentErrorControl : UserControl
{
    protected override void Render( HtmlTextWriter writer )
    {
        //call the base's render method, but with a try catch
        try { base.Render( writer ); }
        catch ( Exception ex ) { /*do nothing*/ }
    }
}

Then inherit SilentErrorControl instead of UserControl.
