c# - wp8: programmatically created textblock is not displayed in app? -

well,

i have created textblock programmatically in c#. not displayed in app. whats wrong ?

here's updated c# code:

            double left = 0, top = 15, right = 0, bottom = 0;             double left1 = 0, top1 = 12, right1 = 0, bottom1 = 12;             textblock filename = new textblock();             filename.margin = new thickness(left, top, right, bottom);             filename.fontsize = 30;             filename.foreground = new solidcolorbrush(colors.white);             filename.textalignment = textalignment.center;             filename.text = "hello";             stackpanel content = new stackpanel();             content.margin = new thickness(left1, top1, right1, bottom1);             content.setvalue(grid.rowproperty, 0);             content.children.add(filename);; 

you've added textblock stackpanel haven't added stackpanel visual tree. assuming want add layoutroot, can this

layoutroot.children.add(content); 

as side note, there reason you're doing programmatically? depending on situation, might better off using usercontrol.
