Okay, got your point. You have text in a textbox which is wrapped and you want to adjust the margins/padding and line spacing between the wrapped lines, right? If yes then I don't recommend you that because they are the default behaviour of textbox property and they were used to show your full text without cut in different display screen. If you still want to do that then 2 ways are there
1. Remove the border thickness and set the height of textbox to auto (this will remove the line spacing from all aides.2 Right click on the textbox -> edit template then you can adjust the default behaviour of it.

Canvas.SetTop(textBox, 5)   is indicated, question is not position of textbox, question is position and size of text inside textbox.   thanks

If you share the scenario what you want to achieve? However, you can adjust margin to shift the location and padding to adjust the spacing, choose it accordingly.
