Question

Why if I wrote on a .aspx page (on .NET 3.5) :

<%="W&auml;hlen Sie bitte"%>

it prints correctly on my html page :

Wählen Sie bitte

but if I write on a .aspx.cs page somethings like :

mySelectBox.Items.Add(new ListItem("Wählen Sie bitte", ""));

(which is the same string) it prints as option on the select an uncorrectly html :

Wählen Sie bitte

It does a “decode” of my string. Why? And how can I fix it?

Answer 1

ASP.NET controls already HTML encode the output so you don’t need to do it once again.

Simply:

mySelectBox.Items.Add(new ListItem("Wählen Sie bitte", ""));
