Radgrid not updating database asus android weather widget not updating
When Edit link of the Grid View will be clicked then On Row Editing event will fire that will call Edit Record method.
In this method, I am specifying the Edit Index property of the Grid View to the New Edit Index of the Grid View and then calling Bind Data() method again to bind the data.
Please note that when you will not bind the data again, Grid View will not change in edit mode.
When Cancel link is clicked on Grid View in edit mode, On Row Canceling Edit event will fire that will call Cancel Record method.
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.
As there is no row at -1 position so Grid View will be shown in normal mode.
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.
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.
