Sample text

This time, rather than specifying that the action will return an ActionResult, we want to specify that we plan to return an ImageResult and we will pass the path to our image to the constructor of our new ImageResult. jpg"); } 12. Hit F5 and browse to your new action at localhost:{port}/Home/GetImage. How it works... We have basically used one of the many extensibility points in the MVC framework. In this case, we simply extended ActionResult to flush the contents of an image down to the client via the Response object.

We will also allow the requestor to specify whether or not the image can be zoomed (made bigger than the original). NET 4 optional parameter! cs: public ImageResizeResult(string fileName, int width, int maximumHeight, bool noZooming = false) { //put this path reference in a config file somewhere! _path = @"{path to files that can be loaded}\" + fileName; _width = width; _maximumHeight = maximumHeight; _noZooming = noZooming; } 5. Next, we are going to reuse a snippet of code from the last recipe that will allow us to determine the content type (except that we are returning ImageFormat instead of String) of the image that we are playing with, so that it is rendered correctly on the client.

If, while rendering this recipe, you see two master pages, then the odds are that you didn't generate a partial view for your SuggestedProducts view! aspx: ... RenderAction("SuggestedProducts", "Product"); %>

... 8. Now you can run the application. Navigate to /Blog/Index and you should see a list of blog posts. Next to that you should also see a list of suggested products. Notice that our blog controller didn't have to know anything about products in order for it to use the SuggestedProducts view.
