Question

I’m trying to create a GroupBox, add a Grid (or StackPanel) to it then put some TextBlocks on it, all during runtime. This is what i’ve tried

GroupBox groupBox1 = new GroupBox();
Grid grid1 = new Grid();

groupBox1.Width = 85;
groupBox1.Height = 60;
grid1.Height =  85;
grid1.Width =  60;

groupBox1.Content = grid1.Children.Add(textBlock1);
groupBox1.Margin = new Thickness(50, 50, 0, 0);

mainWindow.canvas.Children.Add(groupBox1);

But all I get is a groupbox with a thick white border with nothing in it.

Answer 1

As far as I can see a Grid.Children.Add returns an int and that’s not what you want to set the content of the groupBox1 to.

An untested idea from me as a non WPF expert is to set the grid as the Content of your groupbox.

grid1.Children.Add(textBlock1);
groupBox1.Content = grid1;
