My problem is that the decimal column doesn't update when I enter a 0, 0.0 or other permutations of 0.Works fine with positive or negative values, and the other visible column DOES update.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.

You can also indicate whether the exception was handled in the event-handling method by setting the On Row Updated Row Canceling Edit On Row Canceling Edit Row Deleted On Row Deleted Row Deleting On Row Deleting Row Editing On Row Editing Row Updating On Row Updating Grid View Class System.

event is raised when a row's Edit button is clicked, but before the Grid View control enters edit mode.

In this demo, I presumed that you already have a basic background on how to create a simple database table. Thanks that cmd do not work fine string id = Grid View1.

In this example, this time I used my own database called Sample DB which has Customers Table and basically contains the following field columns: As you have noticed in STEP 2, we have added six Text Box and a Button in the web form in order for us to type the information there and Insert them to the database.

Many a times in our applications we use primary keys to get control of the particular record in the gridview.

For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.

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.

A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.

This demo is a continuation of my previous example “Binding Grid View with Data”. When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values. 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?

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).
