Sort of a continuation from this question. Still working on my module, I'm running into deeper issues with the GridView that I'm using for modifying and deleting "discoverys".

Here is a relevant bit from my .ascx file

EditDiscovery.ascx

And relevant bits from my CodeBehind file

EditDiscovery.ascx.cs I'm having two problems in particular, both of which are related to the custom column that I have set up for editing the Image.

1. When you aren't editing the column, you see an Image. However, because this is an ID and not an actual file, it's not very informative. My plan of attack here is to turn that Eval into a label which fires a method in the codebehind onRender, which will grab the associated file for that ID and write it into the .Text of the label...either that, or write out "Missing Image" if the ID can't be found (if the user deleted the image for example). However, the problem is that when I'm actually in the method for that label, I have no idea how to get access to the data in that row.
2. Line 18 in the codebehind file is a by-product of something similar. I have no idea how to grab the image ID from that method, and if the Image ID doesn't actually exist then the module tosses an error in my face because it doesn't exist in the drop down list. So I just set it to -1 always (which represents the blank entry on the data dictionary).
3. One other issue with this setup is that when I update an entry in the gridview, the CreatedByUser field blanks to a 0. No idea why.

Any ideas on any of these issues?

For questions like this, you probably want to hang out in forums for ASP.NET developers. Don't worry about it being a DotNetNuke application, at the core, you're just doing c# ASP.NET programming.
