You cannot directly modify a cookie. Instead changing a cookie consists of creating a new cookie with new values and then sending the cookie to the browser to overwrite the old version on the client. So you can use the value as String str= Request.Cookies[Key1].ToSting(); str = str +  more value; Response.Cookies[  Key1  ].Value = str;

Smart Lucky You're not actually appending to the value associated with the key of asp but changing the value associated with the key of Val1. Is that what you intended?

Response.Cookies writes a cookie and Request.Cookies is used to read a cookie So use Response .Cookies[hidaya][Val1] = value +   + Sql Server  Share Point Crystal Report;

Using the cookie you created in your other thread: string value = Request.Cookies[hidaya].Values[Val1]; Request.Cookies[hidaya].Values[Val1] = value +   + whatever;
