Setting Hyperlinks in order for users to carry out forced downloads
-
Hi I am using Microsoft's MVC design pattern and I have a method in my controller, which sets the data source of a gridview. Whilst I can bind all the other values in the gridview, I am stuck setting 4 hyperlinks. The hyperlinks need to work in the explanation given in the link below: http://forums.asp.net/p/542979/3077895.aspx for forcing downloads to keep the location of where files are saved to private, which I want set in the controller. To fully explain what I am doing, in my controller for the gridview, I am setting the gridview's data source using ICollection, which is an object containing results from a query. From this collection, I extract a value which has the name of a folder which contains a number files. So, what I have done is to cast my collection to a object, to get folder name and then use a foreach loop to get each folder name. Then to get the files inside each folder, I use Directory.GetFiles, which returns a string array - I wrote string[] files = Directory.GetFiles(ConfigurationManager.appsettings["filepath"]+folderName); . I have set 4 properties for each Hyperlink I want to set. It is at this point where I am stuck, because even though I can get to the files, I am unable to set the Hyperlinks to these files. Each time I try an set the NavigateUrl property, I get the error message Object not set to an instance of an object. Plus, I have two other issues to resolve: 1) Even though there are 4 hyperlinks, not every hyperlink will be set. In other words, if there are only two files in the folder, I only want to set the appropriate hyperlinks. So, how can I iterate through the string array, and get each value inside the array to do a check? 2) When I set my Hyperlinks in my controller, how do I simply pass the file and keep the file's actual storage location hidden as given in the link http://forums.asp.net/p/542979/3077895.aspx Thanks

When you say "Microsoft's MVC design pattern" you mean you have created an MVC application correct? What version? If you are using a MVC application then you have control of the output and formatting in the markup of view or you can set the ViewData or model appropriately. Perhaps if you showed some of what you are doing it would be clear. Also, as note, if you are including a URL it is customary to make it a hyperlink so people can navigate without copy & paste
