textbox.Focus() not working in C#
Solution 1:
Use Select()
instead:
recipientEmail_tbx.Select();
Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms.

Solution 2:
Add Delay some miliSec
. Delay then call Focus()
and Not forget to put inside Dispatcher
.
Task.Delay(100).ContinueWith(_ =>
{
Application.Current.Dispatcher.Invoke(new Action(() =>
{
TextBoxNAme.Focus();
}));
});
Solution 3:
Even I tried with lots of above solutions but none of them worked for me as am trying to focus on page load. Finally I got this solution and it worked.
private void txtBox_LayoutUpdated(object sender, EventArgs e)
{
txtBox.Focus();
}
