events, user-controls, wpf
Solution
A brief example on how to expose an event from the UserControl that the main window can register:
In your UserControl:
1 . Add the following declaration:
public event EventHandler UserControlClicked;
2 . In your UserControl_Clicked event raise the event like this:
private void UserControl_MouseDown(object sender, MouseButtonEventArgs e)
{
if (UserControlClicked != null)
{
UserControlClicked(this, EventArgs.Empty);
}
}
In your MainWindow:
Your usercontrol will now have a `UserControlClicked` event which you can register to:
<local:UserControl1 x:Name="UC" UserControlClicked="UC_OnUserControlClicked" />
Problem
I have one `UserControl` in which I am using a `Canvas`, and in that Canvas one Rectangle. I want to create a click event for that user control (Canvas and Rectangle) which I then want to use in the main window. The question is: I want to create a new click event for the `UserControl`. How to do it? Kindly show little example or the code.
