I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.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.Run the project and place a breakpoint on the code above. The program will stop on the breakpoint and you will be able to see the selected row index being passed through.You can then use the code below to retrieve the ID value: are a great way to use primary keys without having to display them to the user.

A Data Column can also be used to generate automatically incrementing values by setting the Auto Increment property to true. Following the update, the copy can contain new identity values that must then be merged back into the original property set to Modified, which may be unexpected. This ' Data Table will be used by the Data Adapter.

Open Visual Studio 2008 and create a new Web Application.

This example won’t hook into a database, but we will create a class to mock a table and retrieve data from it instead. This enables you to not display the ID to the user, yet still being able to retrieve it.

NET application by specifying command syntax at design time and, where possible, through the use of stored procedures. For example, the following code ensures that the deleted rows of the table are processed first, then the updated rows, and then the inserted rows.

You must explicitly set the commands before calling event and setting the Status to Skip Current Row. NVar Char, 15, "Category Name") Dim parameter As Sql Parameter = _ adapter.

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: 1.
