I found out that Insert, Edit and Delete in a RadGrid works only when you use Advanced Data Binding. Sadly I don´t find any example of this in the sample/tutorials. Maybe someone can link me an example???

 

In the examples for "Data Editing" in Grid there is only an example with CRUD Operations and nothing with the Advanced Data Binding.

Thanks

Hello Julian,

Your assumption is correct: Advanced data-binding = Programmatic data-binding using NeedDataSource. Performing complex grid operations such as Inserting, Deleting, Updating, Hierarchy relations, Grouping, Exporting, Paging, Sorting, Filtering, etc. require accommodating appropriate database operations.  Therefore, we suggest you to avoid Simple Databinding and strongly recommend the use of more advanced databinding methods, which automatically handle the aforementioned functions:
Declarative DataSource
Programmatic Data Binding


For implementing manual CRUD operations, you can access the control using ItemCommand/UpdateCommand/InsertCommand methods provided by RadGrid and modify the value before passing it to the database:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-editinsert-mode

Alternatively, you can try using the ExtractValues method:

Hope this helps.
