Query string is used to Pass the values or information form one page to another page. Syntax Request.QueryString(variable)[(index)|.Count] Parameters variable :- Specifies the name of the variable in the http query string to retrieve. index :- An optional parameter that enables you to retrieve one of multiple values for variable. It can be any integer value in the range 1 to Request.QueryString(variable).Count. For example:- In page 1: Drag and drop the one textbox and button control In page 2: Drag and drop the one textbox control from tool box and place it on form. In page one:- Partial Class _Default Inherits System.Web.UI.Page Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click 'bind the textbox values to querystring Response.Redirect("Default2.aspx?Textboxvalue=" & TextBox1.Text) End Sub End Class In page two:- Partial Class Default2 Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Get the values from Query string TextBox1.Text = Request.QueryString("Textboxvalue") End Sub End Class
