prevent postback of HtmlButton in C#

Question

I am creating HtmlButton dynamically in .cs file. Adding it to Panel using

HtmlButton b1 = new HtmlButton();
b1.Attribute.Add(\"onclick\",\"javascript:valid         


        

Answer 1

on the javascript function return true or false and then add the return to your onclick as I show here.

    function validateNclick(me)
    {
       if(allIsOk)
       {
         return true;
       }
       else
       {
         return false
        }
    }

and your attribute.

b1.Attribute.Add("onclick","javascript:return validateNclick(this);");
