推荐答案
您将必须在视觉树中导航才能找到此元素。不久前,我写了一个实用程序类,使用如下所示:
You will have to navigate the visual tree to find this element. I wrote a utility class a while back that makes this a little easier, using Linq-to-VisualTree you can find it as follows:
TextBox tb = dgUser.Descendants<TextBox>()
.OfType<TextBox>()
.Where(t => t.Name == "txtcount")
.Single();
