Suppose I have url www.abc.com/orders.aspx?order_id=4321
. So in this page there is one textbox
on which page loads it should get values from url where id = 4321.
So I tried this code but it's not working. Please help
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
If Request.QueryString.HasKeys Then
Dim user As String = Request.QueryString(0).ToString
trackInput.Text = user
End If
End Sub
