What is querystrng? how we can use it? what are the advantages? what are the parameters using for querystring?

Answer 1

query string is one of the state management techniques in .net. You can pass parameters from one page to another page like Response.Redirect(“test.aspx?id=101”); and you can access those values in recieving page.

here it is test.apsx. in test.aspx page load you can retieve those values by

string id = Request.QueryString["id"].ToString();
