有关Scatterview渲染的帮助 [英] Help on Scatterview rendering

问题描述

亲爱的，

我有一个散点图，我动态添加iitems。

我需要做的是当散点图时项目显示，我需要应用ScaleTransform，以便对用户有一种放大效果。

I have a scatterview on which I am adding iitems dynamically.
What I need to do is that when the scatterview items gets displayed, I need to applying a ScaleTransform in order to have a kind of Zoom in effect to the user.

我有的问题是，只要项目获得添加到teh scatterview集合你不能改变任何东西。

The problme i have is that it seems that as long as the items gets added to teh scatterview collection you cannot change anything.

例如我尝试使用简单的opacity属性。当我添加我的scatterview项时，我将其不透明度设置为0.

For example I have try with the simple opacity property. When I add my scatterview item I set its opacity to 0.

然后在scattyerviwItem_Loaded事件中，我执行以下操作：

Then at the scattyerviwItem_Loaded event I do as follwo :

DoubleAnimation opacityAnimation = new DoubleAnimation(0,1, TimeSpan.FromSeconds(1), FillBehavior.Stop);
        svi.BeginAnimation(ScatterViewItem.OpacityProperty, opacityAnimation);

推荐答案

两个选项：

1。您可以在SVI中放置一个画布，并在一段时间内显示内容的缩放版本（超出SVI界限）。

1. you could have a canvas inside your SVI and shows a scaled version of the content (that sticks out of the SVI bounds) for a bit of time.

- 或 -

2。您可以在项目实际添加到ScatterView之前在不同的图层上执行动画。

2. You could perform the animation on a different layer before the item actually gest added to the ScatterView.
