Gridview rowupdating cancel update

In this article, I am going to explain how to manipulate data using Grid View control.

This article scope is limited to Updating and Deleting records using Grid View and I am not using any readymade Data controls for that but manually writing all event methods.

Till now our Grid View is ready to be populated, now let’s write a method to populate the Grid View.

To populate the Grid View, I am calling Bind Data() method from Page_Load event after checking Is Post Back property of the page, so the Grid View will only be populated when there is no postback on the page (when the page loads for the first time).

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.

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.

I have tried to add an event handler to the Row Updated event of my custom control but it is not called.Connect me on | https://twitter.com/sheonarayan | Hello.... On Row Deleting - can call registered event handlers" I couldnt figure out how to continue this thread, but the issues in it are related so i'm including it as a reference.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.

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.

Ratdolt’s figures led directly to those of Jacob de Gheyn (1600) and through him to those of Johannes Bayer (1603).” (Warner, The Sky Explored) The Contents of Hyginus’ “Poeticon Astronomicon” Hyginus tells us that he intends to give a better description of the celestial sphere than Aratus had done in his “De Sphaera”.
