Gridview rowupdating code in asp net Live xxx camblak

Greetings; I have read several of the previous help questions on when the grid View Row Updating event doesn't fire. The routine loading of the product table now happens only on the first pass through the code behind.

I am confused at this point on why my markup and code behind is not touching the Row Updating event when Update button is clicked. The code works as I intended it to (and is listed below).

Please keep in mind that there are many different ways to update the database using the Grid View control depending on the type of data you are updating and the functionality the user need and there are many solutions to achieve the same end result.

In the above tutorial I tried to give you one of the easiest solutions and I hope you can go explore Grid View control editing further after learning the basics from this tutorial.

Editing the Grid View control can be an incredibly easy feature to add for certain database tables, especially those who have no foreign key associated and can easily be edited through the use of a standard Text Box web control as shown in the figure below: Before we start examining the ASP.The visitors to a web site can typically be divided into two groups: the users and the administrators.In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.By Default, Grid View control displays Item Template which directly shows the Product Name and Unit Price columns but when user clicks Edit button Grid View automatically switches to Edit Item Template and display the control available inside Edit Item Template for user editing.Now I will show you the C# code behind file of the above ASP.NET page that will handle different Grid View events to provide complete editing functionality.In the Page_Load event, you simply load your data from the database and bind it with the Grid View control as shown below: For brevity I am not storing connection string in the web.config and also not using any Data Access Component.To do this, I created an instance of the Row Updating event for the Grid View. This event passes the necessary information to the method via the Grid View Update Event Args parameter. Find Control("Label20e"), Label) Sql DSupport Info. Next event is the Grid View Row Editing event to give ASP. You need to set the Edit Index property of the Grid View with the New Edit Index property of the Grid View Edit Event Args class.If user clicks the Cancel button while Grid View is in editing mode, you need to Cancel the Editing process and also need to reset the Edit Index property to -1 in the Row Canceling Edit event of the Grid View control as shown below: The last step is to handle the Row Updating event to actually update the back end database.
