window resize when textbox resize

Question

Answer 1

In WPF you typically place TextBox control within layout Grid control and set the ColumnDefinition Width property of that Grid cell to some relative value "*", so it will resize with the Window. Do NOT use a fixed Width="500" as per your sample: also, remove that "HorizontalAlignment="Left" (the default value is HorizontalAlignment="Stretch", so you can just omit it to simplify your XAML). See the following sample code snippet:

Note: The same technique could be applied to a vertical "Height" property in case you need to make it also resizable.

Hope this will help. Best regards,
