Gridview edit row updating
In this article, I am going to take a simple database table that has following fields: Auto ID - Int, Auto Increment, Primary Key Page Name - Varchar(50) Page Description - Varchar(500) Active - Bit(1) In this article, I am not going to explain the workings of Sql objects but focusing on the events and methods of the Grid View that will help us in updating and deleting the records.
Now let’s start with putting the Grid View on page. Data Key Names="Auto ID" Auto Generate Edit Button="True" On Row Editing="Edit Record" On Row Canceling Edit="Cancel Record" On Row Updating="Update Record" Cell Padding="4" Header Style-Horizontal Align="left" On Row Deleting="Delete Record" Row Style-Vertical Align="Top" Fore Color="#333333" Grid Lines="None" In the above code, I have kept Auto Generate Columns as false so that Grid View will not render all the fields of the data source automatically.
I have specified Data Key Names as Auto ID, the primary key of the database table.
Then I have several methods attached with following events Get video of hundreds of ASP. On Row Editing - Edit Record On Row Cancel Edit - Cancel Record On Row Updating - Update Record On Row Deleting - Delete Record As I set Auto Generate Columns property to false so I am going to manually write the fields name that I need to appear in the way I want.
You can notice that I have kept Required Field Validator too inside the Edit Item Template as I want the textbox to be validated for empty data.
In the same way you can put any kind of Validation controls inside Edit Item Template to validate the form element while user will click Update link.
Hope this article helps to begin working with Grid View control. Right now I have a label turn to visible true and a message when someone either edits or deletes something successfully.
If you choose to participate, the online survey will be presented to you when you leave the Msdn Web site. In this method, I am specifying the Edit Index property of the Grid View to -1.As there is no row at -1 position so Grid View will be shown in normal mode.When Update link of the Grid View will be clicked (in edit mode), On Row Updating event will fire that will call Update Record method.In this method, we have to get changed values of Text Box and Drop Down list and also we need the primary key value for the record that is being edited.
