How can I change the TextBox's width with the text Length?












0















I want to remake one kind of game from those typing games, where the words are coming from somewhere and you have to write down that word correctly.



Here is one: https://www.youtube.com/watch?v=FqNTKJRBPdc



My first problem is that I don't find nothing, how could I change dynamically the TextBox's width.



So if the whole word won't fit in the TextBox, I want to increase the TextBox's width. How could I do it?



Here is my View:

you can define a property which you will bind with the width property in xaml page.
You can control the property from viewmodel based on your given condition.
You can control almost everything which is available to you in your window xaml page.Plus you can define conditional logic based on pairing of two properties.
like if your TextContent property reaches certain limit then set text width property to something.



With low level of control you can achieve controlling width via data triggers.



<Style>
<Setter Property="Width" Value="200"/>
<Style.Triggers>
<<Put your conditions which will set the value>>
</Style.Triggers>
</Style>

@AME there could be other ways too but I doubt your "easier solution" because any how you need to involve data binding for the level of control you need.If you requirement if for little control i.e you know precisely how much width you need to keep and on what condition then you can opt for data triggers or other type style triggers.I have edited my answer for one such reference.
