There is one possible pitfall with using textBoxName.Text = string.Empty; and that is if you are using Text binding for your TextBox (i.e. <TextBox Text="{Binding Path=Description}"></TextBox>). In this case, setting an empty string will actually override and break your binding.

To prevent this behavior you have to use the Clear method:

textBoxName.Clear();

This way the TextBox will be cleared, but the binding will be kept intact.

You wouldn t have to put it in the button click hander  If you were  then you d assign your text box a name  x Name  in your view and then use the generated member of the same name in the code behind to set the Text property   If you were avoiding code behind  then you would investigate the MVVM design pattern and data binding  and bind a property on your view model to the text box s Text property
