WPF捕获文本框onBlur事件

Question

I have a textbox in my WPF Application. I am used to web development where you can capture the onBlur events with JavaScript. Is this possible also in my WPF app?

All I am trying to do is NOT have a "Save" button, but to just update the database when they are finished modifying the text.

Answer 1

Did you read all available events descriptions? See: http://msdn.microsoft.com/en-us/library/system.windows.controls.textbox.aspx

I guess you are looking for LostFocus event but you should look for the one that best fits your solution.

Answer 2

Why you want to do it using an event?

In WPF, when you want to update your back logic when you lose focus on a control, you usually use a Binding with UpdateSourceTrigger equal to LostFocus

Just as example

<TextBox Text="{Binding myBackLogicText, UpdateSourceTrigger=LostFocus}"  />
