How to use the ViewBox in WPF


The ViewBox is a very useful control in WPF. If does nothing more than scale to fit the content to the available size. It does not resize the content, but it transforms it. This means that also all text sizes and line widths were scaled. Its about the same behavior as if you set the Stretch property on an Image or Path to Uniform.

Although it can be used to fit any type of control, it's often used for 2D graphics, or to fit a scalable part of a user interface into an screen area.

<Button Content="Test" />
<Viewbox Stretch="Uniform">
    <Button Content="Test" />

Hi Ujval,
The viewbox gives it's content infinite space. Then is measures the size of the content and scales the content, so that is fits into box. That is the reason why textwarpping is not working, because the TextBlock has no reason to wrap the text, if infinite space is available.

Hi Moser ,

I have a problem using the viewbox control. I have a shape derived from frameworkelement. I am getting these shapes dynamically. The dimension of these shapes is very small. What i need to do is to show these shapes to a fixed size enlarged . say (width = 50, height = 50) . How can i do this. What i did is , I made this shape inside a border set it a width and height. Then i put these inside a viewbox and made stretch = fill . But it didnt work as i expected. The shape goes beyond 50 and a lot more.. pls help.

This is way too simplistic to actually be defined as a tutorial on the viewbox. Where is the data binding to the viewbox, the many properties associated with the viewbox and the databinding to those properties. How do you change the view within the viewbox, lets say that little button was a separate user control with it's own code behind containing it's own event handlers and you clicked it and the intent was to send a larger version of the button, scaled to not look like a brick from super mario bros and display it in the viewbox. Not only that what if it had an enumeration of buttons and then you wanted to display them in the viewbox like a dynamic picture viewer. Way to do the bare minimum and stop, you could of at least provided a link that says, for more go to...

hi betsy,
If i get u right, then u can put a contentcontrol inside your viewbox and set the image as the content of the content control. Hope this is what u need.

Can anybody tell me that why i cant set the value from code behind for the child element of Viewbox. For eg., I have the structure like this..


In this structure, I need to display the textblock after animation. I cant able to this by making the visibility property as visible from code behind as well as i cant able to set the text value from code behind.. It shows the error as &quot;Object reference not set&quot;. Can anybody help me out to overcome it..?
