Solution 5

You cant use if-else construct in Eval function. Instead, you can use the syntax in this link which also acts as it were if-else. You can get your solution from here. It is Straight forward, clear and easy.Solution[^]

Solution 1

If you look at the documentation you see DataBinder.Eval returns an Object. Your if statement is trying to compare an Object and an integer, which can't be resolved. Try casting the left side to an integer or making the right side a string.
