WP8 C＃按钮更改单击

Question

I am programming in C# for Windows Phone 8 and have a Windows.System.Controls.Button object which does not have a "Click" event defined in the XML upon page load. However, after certain pieces of data are obtained, I want to set the button's click event to a specific function I have written.

How can this be done? The "OnClick" event is protected, and I can't find which setting to change in the MSDN site.

Answer 1

从代码中你应该可以做一些像MyButton.Click += clickhandler ，从XAML你也可以做到这一点。

Answer 2

You can potentially change the click event of the button by doing the following:

btButton.Click += NewHandler()

Another way, which isn't as clean would be to have a flag that checks if you have reached a specific stage, declared globally.

bool myBool = false;

Then you can change the bool flag to true and check whether it's true in the click event:

if(myBool)
{
   //toDo Logic
}

This way you won't need to create another event handler.
