Silverlight learning notes-create a Silverlight custom control (3)-operation control internal Member

In the above custom control mysilverbutton, we have two internal members: rectangle (bodyelement) and textblock (buttoncaption). To operate on them, we need to use the gettemplatechild function to achieve our goal.
Here, we modify the text attribute value of textblock. Join Code To the simplebutton_mouseleftbuttonup event Void Simplebutton_mouseleftbuttonup ( Object Sender, mousebuttoneventargs E)
{
If (Click ! =   Null )
{
Click ( This , New Routedeventargs ());
Textblock bgtextblock = (Sender As Mysilverbutton ).( " Buttoncaption " ) As Textblock;
Bgtextblock. Text =   " Modify display text " ;
}
}

The complete code of mysilverbutton. CS is as follows: Using System;
Using System. net;
Using System. windows;
Using System. Windows. controls;
Using System. Windows. documents;
Using System. Windows. Ink;
Using System. Windows. input;
Using System. Windows. Media;
Using System. Windows. Media. animation;
Using System. Windows. shapes;

Namespace Mydesignbutton
{
Public   Class Mysilverbutton: contentcontrol
{
Public   Event Routedeventhandler click; // Add a click event

Public Mysilverbutton ()
{
This . Defaultstylekey =   Typeof (Mysilverbutton );

This. Mouseleftbuttonup+ = NewMousebuttoneventhandler (simplebutton_mouseleftbuttonup );//Add a click event

}

// Add a click event
Void Simplebutton_mouseleftbuttonup ( Object Sender, mousebuttoneventargs E)
{
If (Click ! =   Null )
{
Click ( This , New Routedeventargs ());
Textblock bgtextblock = (Sender As Mysilverbutton ).( " Buttoncaption " ) As Textblock;
Bgtextblock. Text =   " Modify display text " ;
}
}

}
}

Re-Generate and return to the myslbutton project to run the test. You can see the result.
