如何使用户控件中的文本框不关注负载？

Question

I have a XAML page where, upon tapping an "Add" button, I create a UserControl and add it to my Container. This UserControl has a Rectangle, a TextBox and a few buttons. My problem is that on the first click of the "Add" button, the focus is given to the Textbox. Clicking on the "Add" button repeatedly creates more UserControl instances, but focus remains on TextBox1. If I now click on Textbox5, that box gets focus, but as soon as I click outside, focus returns to Textbox1. I would like focus to be given to textboxes, only on click.

I have tried setting IsTabStop = true in XAML, and intercepting the tapped event and setting it to false, but that doesn't have a noticeable effect.

What worked perfectly is setting the TextBox's TabIndex = 2, and creating another button before it, and setting it's TabIndex = 1. But I lose this benefit when I set the Button's Visibility = Collapsed. The TextBox is the left most control, so it must have the lowest TabIndex (well technically, there is a Rectangle to the left of the TextBox, but since a Rectangle is not a Control, it cannot have a TabIndex).

How can I fix this?

I believe what is happening is when you are adding more controls, it is resetting the current tab stop index. So every time you add a control, the TextBox of TabStop 1 is being focused on.

What you can do, is after you add the control, call Focus() on the control that you want to be focused.
