Gridview updating event in asp net Arab privatecam
Future installments will explore more advanced updating scenarios, such as customizing the Grid View's editing interface and programmatically setting the updated values. The UPDATE Table Name SET Column Name1 = @Parameter Value1 Column Name2 = @Parameter Value2 ...Column Name N = @Parameter Value N WHERE Primary Key Column Name1 = @Primary Key Value To Update1 AND Primary Key Column Name2 = @Primary Key Value To Update2 AND ...A Sql Data Source control was added whose Insert Parameters referred to these controls.The Web Form also included a Button whose method, thereby kicking off the inserting workflow.Updating data through manually-created Web Forms is a bit more difficult and less practical because the Web controls that make up the updating interface must also be populated with the values of the record being edited.AND Primary Key Column Name N = @Primary Key Value To Update N , in this instance - has its value specified via the data source control's Select Parameters, which can specify a source for the parameter value.The source may be: a hard-coded value like "3.95", which would return all products less than .95; the value of a Web control on the page, allowing the user to enter a price bound in a Text Box; from the querystring; from session state; and so on.

In particular, we look at enabling editing support in the Grid View. This article focuses on the Sql Data Source control; for a detailed look at updating with the Object Data Source, refer to the "Editing, Inserting, and Deleting" tutorials in my Working with Data in ASP.
