Grid row updating
Also, how many rows are being rendered in the grid at the same time, what is the page size?There will be a limit to how many rows can be rendered, otherwise the size of the DOM gets too big and the whole page slows down. ukasz, The code that you have pasted looks OK, as long as data Source.data() is called only once for all changes that you need to make for all data items at a certain time, and not once for each data item.FYI: I’m using North Wind Database Employees table, VS 2012, . Create a new WPF project; you may call it “Wpf Data Grid Update Insert Delete” 2. NET Entity Data Model” to the project, select “Generate from Database” and select “North Wind.dbo” as your Data Connection. Besides adding the above code to the xaml, you need to save the observable collection back to the context, hence, make sure that once the user has move to the next or prior row, the context is saved by adding: context.Save Changes(); INSERT records by moving to the next/prior row: Ok, this is a little more complicated because you need to make sure the user is inserting a record.In practical scenario you should use your existing architecture to populate and update the data.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.If you choose to participate, the online survey will be presented to you when you leave the Msdn Web site.
The updating features of the grid provide a wide array of adding and editing values of the underling set of data bound to the grid.
If it did, then is does not matter what the sort order or grouping is.
If you are updating all the rows of the grid, what is wrong with using the built-in refresh/read?
Here I created a Boolean value is Insert Mode which is set to false unless the user is actually inserting a record, if the user is only updating a record the is Insert Mode needs to be false.
To set the Boolean is Insert Mode to true I use the Adding New Item event handler of the grid.
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.
