我的任务
分享PropertyGrid中如何人为控制SelectedGridItem
目前制作的一部分功能的属性通过PropertyGrid显示，对于不同功能选择时呈现对应功能的属性并将该属性ITem选中，所以是想要人为控制Item的选择，一直没有找到方法控制Item的选择，请教大神们。

制作一个图形编辑软件，图形的属性利用PropertyGrid显示，主要涉及了SelectedObject，当使用SelectedObject这个函数时，绘制图形的坐标就会被改变，即使SelectedObject不指向图形属性直接给其赋值个字符串，也会影响我的图形坐标，每次选中图形的特征点都会更改特征点的坐标值，有没有谁遇到这样的问题，绘图和属性控件两个不相干的为什么会互相影响，请教大神们。。。[/quote]可以考虑换一种方法
