NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.
In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.
The last parameter is a boolean value which tells the method whether to execute an Insert (false) or Update (true). In-order to perform Edit and Update in Grid View we need to use three events ( Grid View_Row Editing, Grid View_Row Canceling Edit , Grid View_Row Updating).
For those who do not know on how to generate Events in Grid View you can follow these steps below: I have a project that I coppied the above code into.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.
The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.

Contol)Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System.
Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.
