With this article, I will tell you about sending data to another page using jQuery with QueryString in ASP.NET 5. The page PassDataJQueryQueryString.aspx (Source Page), this is the page from where we want to send the data (value). The page consists of an TextBox for Name ,TextBox for Qualification and DropDownList for Technology whose values we need to send to the other page ( In this tutorial I named it: DestinationPage.aspx).
