diffrence between .ascx i .cs

[kubasa]

i have problem with display text : "My street & # 4 3 ;"in my textbox control When i do that in code behind in my page (i.e in some method tbxCompanyAddress.Text = "My street & # 4 3 ;" ) i receive the same text it means :"My street & # 4 3 ;" in textbox .But if i put that text not in behindcode but only in .ascx in text box property (<asp:TextBox ID="tbxCompanyAddress" Text="My street & # 4 3 ;".../>) i receive "My street +" which is requiered!. Why codebehind dosen't work? Please help. P.s There are white spaces between -> & # 4 3 ;<- to show what html entities is input.
