Solve the problem that the constructor Cannot initialize the interface with the business logic IDE.

In the design view, the integrated development environment (IDE) needs to pre-process Part Of The XAML andCodeTo display the interface, the code will be run into the constructor. You may write some business logic in the constructor, so that preprocessing is not allowed, therefore, you cannot see the interface in the development environment. The solution is as follows:

Use designerproperties. getisindesignmode (this) in the constructor to determine whether the design is in IDE.

Public initialpage ()
{
Initializecomponent ();

If (! Designerproperties. getisindesignmode (this ))
{
// Your initial code

}
}
