Question

I have a textbox for date. It has calender control extender to select date. I want to keep this textbox type protected. i.e. user must enter date by selecting date from calender control only and not allowed to type the date. I tried to keep textbox read-only but it is not solving the purpose..
How can I do so…???

I’m suspect that there is a problem with ReadOnly property that textbox loses his state on postback. Try to use readonly attribute instead of the ReadOnly property. Fot that purpose add following code to Page_PreRender method: TextBox1.Attributes["readonly"] = "readonly";
