How to bind to an Image using a dynamic URL in WPF?
data-binding, image, wpf
Solution
Do you have a employee object in your code? If so you could expose a URI property which is built based on the employee ID of the object.
Otherwise could you have a asp.net page on your website which serves up a image (I have no idea if this will work, it is a idea though)
so have something like this in your xaml
<Image Source="{Binding Path=EmployeeId, StringFormat='http://my.url.com/Image.aspx?employeeId={0}'}" />
Image.aspx would stream the image based on the employeeId get variable?
As I said there is probably a bit wrong with this but it could work, I think the URI property on a employee class would be the cleanest option though.
Problem
I am new to WPF so hopefully I phrased the question correctly. What I'd like to do is bind my `<Image>` to an image online. However, the image I would like to bind to changes depending on the state of the application. For example, if I wanted to bind to an Employee selected from a list, I'd retrieve a base URL from my App.config and append the image name using the ID of the employee, like so: ``` var baseUrl = ConfigurationSettings.AppSettings["BaseImageUrl"]; var imageUrl = String.Format("{0}/{1}.jpg", baseUrl, employeeID); ``` The problem is, I'm not sure how to do this declaratively in WPF. Any help is greatly appreciated!
