Creating and deleting controls dynamically in WPF

Source: Dynamic creation and deletion of controls in WPF

Dynamically creating controls

1. Container controls. Registername ("Name", the control to register)? Registering controls

2. Container controls. FindName ("Name") as? Control type??????//Find the control and convert it to the appropriate type

Note: Only through controls. Name to set is not available through FindName to find the control, must register
dynamically deleting Controls
1. Container controls. Children.remove (Control)????????????? Remove a control

2. Container controls. Unregistername ("Name")??????????? Cancel Registration

Other settings

1. Controls. SetValue (grid.rowproperty, 0);??????????//Set the number of rows in the Grid panel of the control
?? control. SetValue (Grid.columnproperty, 1);??????? //sets the number of columns of the control in the grid panel

2.canvas.setleft ("Control name", ";?????????????????")// Set the horizontal axis of the control in the Canvas panel
? ? Canvas.settop ("Control name", ";?????????????????/.) Set the ordinate of the control in the canvas panel

eg

Add a button to the canvas when you click the Button_add button;

Remove the newly added button when you click Button_remove;

Set: Canvas's name is canvas

Code:

private void Button_Add_Click(object sender, System.Windows.RoutedEventArgs e)        {            Button btn = new Button();            //btn.Name = "newButton";//这里设置的Name是找不到的            btn.Width = 100;            btn.Height= 50;            canvas.Children.Add(btn);            canvas.RegisterName("newButton", btn);//注册名字，以便以后使用        }        private void Button_Remove_Click(object sender, RoutedEventArgs e)        {            Button btn = canvas.FindName("newButton") as Button;//找到刚新添加的按钮            if (btn != null)//判断是否找到，以免在未添加前就误点了            {                canvas.Children.Remove(btn);//移除对应按钮控件                canvas.UnregisterName("newButton");//还需要把对用的名字注销掉，否则再次点击Button_Add会报错            }        }

Run it and you can.
