Is it possible to add Controls via a loop to a Control? The difficulty is the name: it is the same in each circulation, so I get only one Control named hu and not 10. How can I modify the code to get 10 Borders?
for (int i = 0; i < 10; i++)
{
Border hu = new Border();
hu.Width = 10;
hu.Height = 10;
hu.Margin = new Thickness(10 * i);
hu.Background = (Brush) typeof(Brushes).GetProperty(Felder[i]).GetValue(null, null);
mastergrid.Children.Add(hu);
}
At first, yes it is possible. What you can do is to set the Name like this
hu.Name = string.Format("Border_{0}", i);
Maybe not in the case of border, but for example a button. How can i get the data that is responsible for the control in an event, because you bind one event to several controls. Usually use the Control.Tag Property to add additional data and use them in a event. For example:
public MainWindow()
{
InitializeComponent();
for (int i = 0; i < 10; i++)
{
Border hu = new Border();
hu.Width = 10;
hu.Height = 10;
hu.Margin = new Thickness(10 * i);
hu.Tag = anyObject;
hu.MouseDown += new MouseButtonEventHandler(hu_MouseDown);
}
}
void hu_MouseDown(object sender, MouseButtonEventArgs e)
{
Border b = (Border)sender;
// b.Tag contains your "anyObject"
}
Update
Be aware that the name of the variable that holds your instance, in your case "hu", is NOT the same as the Name Property of your Control.
hu is the name of the instance. It's the name of the variable holding the instance. There could be several variables holding the same instance.In your code, you don't create several controls named "hu". You create several unnamed controls, the name of the local variable doesn't matter. And doing so should be completely fine, unless you need the name. If you do, you can just create some unique name for each control.
