Create a pop-up window in DataGrid This article comes from DotNetJunkie. He originally writes the letter to provide an example of how to create HyperLinkColumn in DataGrid, you can open a new window after the user clicks this column, showing the details of this column. We have answered them through Email, he suggested that we have added this method to their guidelines, so there is this article. Like our original article, it is very simple, but simple-containing method examples can sense developers more effectively. This example contains two WebForms and a CSS file (all code can be downloaded) - the first WebForm contains a DataGrid of the product list read from the Northwind library, and HyperLink's State is set to "SEEDETAILS", once this The link is clicked, and the JavaScript clip will call. The user wants to get the product's ProductID as a parameter in the URL. The second WebForms containing another DataGrid lists all the specific users of the product. detail.
Let's take a look at DataGrid-Open.aspx.csdataGrid-open.aspx.csdataGrid-open.aspx <% @ page language = "c #" codebehind = "DataGrid-open.aspx.cs" autoeventwireup = "inherits =" Study.DataGrid_open "%>

<p>In addition to DataNavigateURLFORMATSTRING, there is no difficulty, you can notice that I actually use a JavaScript clip (Note: You can also create a .js file or use <script> </ script> in WebForm, JavaScript Universal, so this is no longer explained in detail. Function, it opens a new window, with the ProductID query string DataGrid_show.aspx, ProductId's value comes from our data source.
