MessageBox in Asp.net(C#)

[Limno]

Hi

I m using this code to display messagebox in Asp.net

ClientScript.RegisterStartupScript(this.GetType(), "msg", "alert('Date Already Allocated');", true);

But it shows only OK button, i need two options ie. Yes or No.

How i can do this by using ClientScript. is there any options to do this message as i want.

Reply me.
