Hi Good Evening friends,

I gone through many articals for getting focus on text box on button click.

but i am unable to understand. because there is no tutorial or a particular blog. in all the post only discussion is going on.
and i am new to wpf and mvvm. i was trying to make a wpf application but after designing form in wpf. i have one new button and in that i want if i click on new button first text box should be focused. or then if any error occurs due to validation the perticualr textbox should be focused.
so can anybody help me to do that in a easiest way that i can understand easily.
i would be grateful if anybody could help me.

Thanks in advance

This can be as simple as MyTextBox.Focus. It will work, first of all, because you are asking to do it on button press, when everything is rendered and shown on screen. But in many cases you may need to solve more sophisticated problems of focusing, which is not a trivial WPF topic: http://msdn.microsoft.com/en-us/library/aa969768%28v=vs.110%29.aspx[^].

I don't know why would you need a "particular blog" on this. Original documentation is usually enough.

But first of all, I would advise to review your UI design. Focusing something on button click sounds weird.
