Listbox in asp.net not getting selected items

Question

I have multiple dropdown & listbox in my webpage.

I am trying to get a list of CategoryID from a lstCatID listbox i am able to populate

Answer 1

I am not sure what is wrong with the logic i am using.

I came across a nice solution using LINQ.

This single statement works great & gets me the desired results.

string values = String.Join(", ", lstCatID.Items.Cast().Where(i => i.Selected).Select(i => i.Value).ToArray());

RESULT: 3,29,25
