Datatable rowstate not updating
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.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 just tried same but in my case I received "Table can not be found! Then i figured out if my query didn't return empty result set , but instead returned error , above method won't work. The code I'm writing calls the method like this Data Set ds = Get Results(sql, conn). Instead simple but easier way is to use check for ds. Looping through tables and counting rows will definitely work, but check out the Extended Properties property of Data Set, which would allow you to set this kind of custom information from within Get Results() and use it upon return. 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.
Connection pooling reuses existing active connections with the same connection string instead of creating new connections when a request is made to the database. You can use these components (or classes) with or without data providers.The Data Set consists of a collection of tables, rows, columns and relationships.So I have to specify how I want them to appear in the normal view and edit view.That’s why I have placed different templates like Item Template (for normal view) and Edit Item Template (for edit view).
