Hi Rajkamal,


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.

Example

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

hi,

A query string is information that is appended to the end of a page URL.
Example:

http://localhost:300/default.aspx?id=1000

and you can retrieve it from serverside.

var id = Request.QueryString["id"];
