I have an ASP.NET form for currency exchange requests. There are two text fields there: amount-source and amount-target.
One of them must be filled and only one.

Answer Snippets (Read the full thread at stackoverflow):
You can use Custom Validators for this:
<asp:Textbox id="textbox1)) args.IsValid = false; else args.IsValid = true; }
If you're using jQuery please comment...this can all.
Then both are in a error state.
