What is the Querystrings?

Posted By:varun bansal       Posted Date: July 28, 2009    Points: 25    Category: ASP.NET    URL: http://www.dotnetspark.com  

By Query string variables, you can pass data between webforms in application.
Below is an example


Suppose you want to pass the value of TextBox1.Text variable from page default1 to default2 on button click event. then write below code.
protected void Button1_Click(object sender, EventArgs e)
Response.Redirect("default2.aspx?id=" + TextBox1.Text);

Now, Read the value of  "id" (from query string) in default2.

use the below code

protected void Page_Load()
string queryStringID = Request.QueryString["id"];
//Now variable queryStringID will hold the data from the querystring.
