Question

I got a great response the last time I posted here.

I have the following table structure in my database for a small Gallery page on my site.

id | title | img1 | img1sml | img2 | img2sml | img3 | img3sml

Now, id and title are mandatory, however the rest are not.

I’d like to loop through all my sml columns that have values in them and create <img src="--column value here--" /> for each of them.

I’d also like to do the same with my img columns – loop through any non-empty columns and list them

Can someone show me how I can do this?

Many thanks for any help with this

You can check NULL as follows

if(!YourObject.Equals(System.DBNull.Value))
