Myth Self Note 7: C# WPF - clear usercontrol

i - stkBody children name 'usercontrolA' should be remove when btnStart is click. And 'usercontrolA' will be replace with other usercontrol
ii - usercontrolA : stkMain, stkLeft, stkRight, btnStart

To clear the stkBody children (in this case is usercontrolA), use stkBody.Children.clear();
But we can't access stkBody within the 'usercontrolA' body itself.

When declaring and adding usercontrolA to the stkBody children, declare btnStart

usercontrolA usercontrolA = new usercontrolA();
usercontrolA.btnStart.Click += new RoutedEventHandler(btnStart_Click);

void btnScan_Click(object sender, RoutedEventArgs e)

Myth Self Note 6: C# WPF - clear parent

1 - image above is a "usercontrol" which is included in another stack 'stkBody'
2 - motive : want to clear stack 'stkMain' when button 'btnStart' is clicked


*stkLeft or stkRight, each can be use because we want to select its parent.

3 - motive : want to remove 'stkLeft' when 'btnStart' is clicked


themythstoodstill: in btnStart_Click event, can't access the stkMain.
