Display string as HTML in GridView

Asked by GY1680 in Programming for ASP.NET, C# Programming Language

Tags: ASP.NET C# string html gridview

I'm attempting to get a list of files in a directly. I've been able to retrieve all the files and populate a datatable and assign the gridview datasource and the list is appearing as I want. The only challenge is I'd like to provide a hyperlink in the "name" column so as to allow the user to click the link and open the file. I've got the string in html, but it's displaying as plain text and I'm not sure how to ensure that the aspx page interprets the html so as to provide a link. Please advise. Coee attached.
