I've created two pages (page1 & page2) in page1 there are some textboxes . after filling all of them user should click on a button to go to next page so that the text of one of those textboxes will be shown in the label which is provided in page2.
in page 2 I've written <%@ PreviousPageType VirtualPath="~/Default.aspx" %> in page2.aspx then Label1.Text = PreviousPage.customer; in page2.aspx.cs
and in page1.aspx.cs
public string customer { get{ return textbox1.Text; } }
but I faced this error >> Object reference not set to an instance of an object.
