Hi,
First of all question is not clear about what you want and what have you tried to resolve your problem.
You have few options as per my understanding. Using Query string is one among them.
Using a Query String:
When you use a hyperlink or Response.Redirect to navigate from one page to another, you can add information in a query string at the end of the URL.
1. In the source Web Forms page when you specify the URL of the target page, include the information that you want to pass in the form of key-value pairs at the end of the URL. The first pair is preceded by a question mark (?) and subsequent pairs are preceded by ampersands(&), as shown in the following example:
http:
http:
2. In the target page, access query string values by using the QueryString property of the HttpRequest object, as shown in the following example:
String s = Request.QueryString["field1"];
Using Session State:
Information in session state is available to all ASP.NET Web Forms pages in the current application. However, session state takes server memory, and the information is stored until the session expires, which can be more overhead than you want for simply passing information to the next page.
To use session state to pass information
1. In the source page, save the information that you want to pass in session state, as shown in the following example:
Session["field1"] = "value1";
2. In the target page, read the saved information from session state, as shown in the following example:
string field1 = (string)(Session["field1"]);
