What happens with this is that the source is being created every time the user submits the page.

This means that when the user does an update, the data from that update is lost.

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". Before we start to write code, we need install Sql Server 2008 R2 Express and create a database file as the data source of Grid View control.

Do you have some sort of Java Script functionality that may be stopping it? A common problem people have with Grid Views is understanding when to data bind the data source to the Grid View.

-Frinny Hi all, I seem to be having the same issue but I don't quite follow the trouble with the above post. Can you explain the T/S a little more or maybe point me to another post that may have already covered it? Hi all, I seem to be having the same issue but I don't quite follow the trouble with the above post. Can you explain the T/S a little more or maybe point me to another post that may have already covered it? It's quite common that people create the data source and bind this source to the Grid View in their Page_Load() method.

The Grid View is used to display, edit and delete the data of database file, the Text Box and Link Button are used to insert new items to the data table.

In the first step, check your controls and rename them and set some basic properties of the Grid View, such as Grid View's templates and events. Copy the Page_Load and Bind Grid View methods of the sample and paste them to your Data From Data vb file, and navigator to the Property panel and switch to Event. Page Size = 15 ' Enable the Grid View sorting option. Allow Sorting = True ' Initialize the sorting expression. Row Data Bound Event Protected Sub gv Person_Row Data Bound(By Val sender As Object, By Val e As Grid View Row Event Args) ' Make sure the current Grid View Row is a data row.

It seems like the Java Script can get mangled otherwise.

If this was based on roles you could use the multiview panel but not sure if you could do the same against a property of the record. In your rowdatabound event you can hide or show the button in it.

You can hide a Command Field or Button Field based on the position (index) in the Grid View.

Dim da As New Sql Data Adapter(str Select Cmd, conn) ' Open the connection conn.

Yes, I did put the breakpoint at the Row Updating line (and not in the function).
