Add-New-Record for any type of collection bound to the XamDataGrid John Doe / Monday, November 23, 2009 Currently, the XamDataGrid supports the AddNewRecord functionality for only collections which implement the IBindingList interface( like BindingList<T> and DataView). With couple of easy tricks and few lines of code, you can achieve a similar functionality for any collection: 1. Distinguish between a normal record and the add record - use the Tag property. 2. Fix the Add New Record so that it looks like the real one - use IsFixed property. 3. Commit the Add New Record - DataPresenterCommands.CommitChangesToActiveRecord. 4. Restyle the Add New Record - Styles for the DataRecordCellArea & RecordSelector. You can find a full sample in the attachments of this blog post. Known possible drawbacks : 1. One extra blank record is present in the data source at all times ( as the built-in functionality creates this record once you have started data input in the add record). 2. The implementation for hierarchical data structure is left out for your exercise. CustomAddNewRecord.zip
