When we design the foreground interface using WPF, we often rewrite the data template or put the control in the data template. But once the control is placed in the data template, there is no way to get it through the name of the control in the background, and there is no way to manipulate it (for example, to hide, to change a value of the control).

WPF uses user controls to embed Web pages, directly using WebBrowser or frame will produce an error, with the following error message:1. Use Webbrowser,2.

In the previous article "List of the third item in the WPF game series", the item list was demonstrated, and the same group of controls (such as) were repeatedly used ), in addition, Yan Changgang also pointed out that there are too many C # code used in 3.2.2. In fact, I also share the same feeling when writing these code, which is indeed cumbersome and difficult to maintain. In fact, the structure of this

Recently, a project needs to load a large number of controls, causing the system to appear in the problem, after a few days of effort, finally took care of, write a memo.The solution is to display only the visible area control when it is first loaded, and then batch-load it with a worker thread, setting the priority level of the batch-loaded thread to idle, so that there is no lag caused by the load thread when the user operates. 1 dispatcher.invoke (

To use these two files, copy them to the project:
Then place a named Border element in the place where you want to load WebBrowser:
Then set it in the background Code as follows:
In this way, your original Border location will be loaded into a WebBrowser.
Its principle seems to be to use a new form without irregular shapes and transparency to carry WebBrowser, which avoids the flexibility problem we encountered before, and
