Step 2: We will see a Gird View control on the page, you can add, edit, delete the columns of the Grid View control, the data is come from App_Data/Grid file, and the Grid View's status is stored in View State for persisting data across postbacks.

Step 3: The Grid View the page size is 15, you need insert 16 Persons in this Grid View to see the next page. NET Empty Web Application" in Visual Studio 2010 or Visual Web Developer 2010. The project includes two web form pages for demonstrating two ways to bind data source with the Grid View, name them as "Data From Data Base.aspx", "Data In Memory.aspx".

Text; bit when ichange it to string id =((Text Box) Grid View1. Line 136: Source Error: Line 134: string Um = ((Text Box)Grid View1. If you are not familiar of binding the Grid View the way then I would suggest looking at my previous example first before you proceed to this example. Parameter name: index Any idea what I need to do to fix this issue? This calls for some extra coding from developer's end. As an example we are going to use Employees table of the Northwind database. Add three Bound Fields and a Command Field to the Grid View with the help of Fields dialog (see below).In order to develop a test web form create a new web site in VS. Set various properties of the Bound Fields as shown in the following table: Here, we call Bind Grid() method if the web form is being served as a result of first request.
