Does version 3.0 supports ObservableCollection for editing and adding new record? Or we still have to use IBindingList Interface.

If yes can you guide me with any examples.

Thanks

Version 3.0 supports insertion and editing in almost any data source with or without IBindingList. For example, the following code demonstrates how to bind the grid, through a DataGridCollectionViewSource, to an ObservableCollection of "Person" objects. The InsertionRow added to the FixedHeaders allows new items to be added to the collection.

   <Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">

      <Grid.Resources>

         <xcdg:DataGridCollectionViewSource x:Key="cvs_persons"

                                            Source="{Binding Path=PersonsCollection}"/>

      </Grid.Resources>

      <xcdg:DataGridControl x:Name="PersonsGrid"

                            ItemsSource="{Binding Source={StaticResource cvs_persons}}">

         <xcdg:DataGridControl.View>

            <xcdg:TableView>

               <xcdg:TableView.FixedHeaders>

                  <DataTemplate>

                     <xcdg:InsertionRow/>

                  </DataTemplate>

               </xcdg:TableView.FixedHeaders>

            </xcdg:TableView>

         </xcdg:DataGridControl.View>

      </xcdg:DataGridControl>

   </Grid> 

If you want to manually handle how items are inserted, you can handle the insertion events exposed by the DataGridCollectionView[Source] classes. See Inserting Data (http://doc.xceedsoft.com/products/XceedWpfDataGrid/Inserting_Data.html) in the documentation.

Thanks for the reply. Actually in version 2.0 I was not able to insert records as exception would be thrown where it complains that cannot insert as the datasource is not a proper one.

 After doing much research it turns out that I need to implement IBindingList interface to support that.

 Anyway I found the link on the version 3.0 where "Example 1: Manually handling the insertion process"

 

Based on version 3.0 when I am implementing insert I am getting exception "When manually handling the item-insertion process the CreatingNewItem, CommittingNewItem, and CancelingNewItem events must all be handled."

 Even though I am implementing all the events mentioned in the example and have also paced them in XAML

 <xcdg:DataGridCollectionViewSource x:Key="cvs_persons"
                                       Source="{Binding Source={x:Static Application.Current},
                                                        Path=PersonList}"
                                       CreatingNewItem="CollectionView_CreatingNewItem"
                                       CommittingNewItem="CollectionView_CommittingNewItem"
                                       CancelingNewItem="CollectionView_CancelingNewItem"/

C#

Copy Code

private void CollectionView_CreatingNewItem( object sender, DataGridCreatingNewItemEventArgs e ) {  e.NewItem = new Person( Person.AutoIncrementID, string.Empty, string.Empty, -1 );  e.Handled = true; } private void CollectionView_CommittingNewItem( object sender, DataGridCommittingNewItemEventArgs e ) {  List<Person> source = e.CollectionView.SourceCollection as List<Person>;  source.Add( ( Person )e.Item );  Person.AutoIncrementID = Person.AutoIncrementID + 1;  // the new item is always added at the end of the list.       e.Index = source.Count - 1;  e.NewCount = source.Count;  e.Handled = true; } private void CollectionView_CancelingNewItem( object sender, DataGridItemHandledEventArgs e ) {  // Manually handling the insertion of new items requires that the CreatingNewItem,  // CommitingNewItem, and CancelingNewItem events must all be handled even if nothing  // is done in the event.  e.Handled = true; }

 What could be wrong?

 

 

 

The code you provided is from the documentation. I assume that you have set e.Handled to true in all 3 event handlers as well?

Thanks for your prompt reply. Yes I found the bug and I was missing one of the e.Handled = true; statement.

I am good for now.

Thanks
