Set focus to TextBox

Question

In my WindowsPhone application I have a Text Box that needs to receive focus at a given time. What I've tried so far:

textBox1.Focus();

---

textBox1.UpdateLayout();
textBox1.Focus();

---

textBox1.IsTabStop = true;
textBox1.UpdateLayout();
textBox1.Focus();

---

textBox1.IsTabStop = true;
textBox1.Focus();

Nothing seems to work. In the Emulator, when the Focus() method is called, the keyboard starts to rise, but then crashes back. The TextBox has IsTabStop set to true in the properties.

Answer 1

Does this help?

this.ActiveControl = textBox1;
