Set focus on a textbox control in UserControl in wpf

I have created an UserControl which is loaded in a View (Window) in WPF. In my user control I have put a TextBox. I am unable to set focus on this

Another option that you have is to create a bool IsFocusedproperty in your view model. Then you can add a DataTrigger to set the focus when this property is true:

Note that at times, you may need to set it to false first to get it to focus (only when it is already true):

IsFocused = false;
IsFocused = true;
