Silverlight繁忙指示器VB

问题描述

页面加载后如何使用忙碌指示器?

我在页面上加载了多个网格.

这给我的页面加载错误:

How do I work with the busy indicator when the page is loaded?

I have multiple grids loading on the page.

This is giving me errors on the page load:

busyIndicator.IsBusy = True
        'busyIndicator.BusyContent = "Fetching Data...";

        ThreadPool.QueueUserWorkItem()
        Thread.Sleep(3 * 1000)
        Dispatcher.BeginInvoke(InlineAssignHelper(busyIndicator.IsBusy, False))
