I am trying to add a required fields validator programmatically in asp.net. But I get the following error message - Control 'req2' of type 'RequiredFieldValidator' must be placed inside a form tag with runat=server The c# code I have used is below - protected void Page_Load(object sender, EventArgs e) { RequiredFieldValidator rv = new RequiredFieldValidator(); rv. ID = "req2"; rv.

ControlToValidate = "TextBox2"; rv. ErrorMessage = "Data Required"; this.Controls. Add(rv); } Could someone tell me whats gone wrong here?

Add(rv).

Yeah that worked. Thanks Smazy! – IrfanRaza Dec 18 '09 at 7:25.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
