There are at least three ways of doing this: Modify the DataGrid’s columns manually from code-behind Use a DataTable as the ItemsSource * Use a CustomTypeDescriptor *recommended for simplicity 1st approach: use code-behind to generate the DataGrid’s columns at runtime. This is simple to implement, but maybe feels a bit hackish, especially if you’re using … Read more
You can also use the DataSet’s AcceptChanges() method to apply the deletes fully. ds.Tables[0].Rows[0].Delete(); ds.AcceptChanges();
No need for attached behaviors or custom DataGrid subclasses here. In your DataGrid, bind ItemsSource to an ICollectionView. The trick here is to set IsSynchronizedWithCurrentItem=”True” which means the selected row will be the current item. The second part of the trick is to bind CommandParameter to the current item with the forward slash syntax. When … Read more

ItemsSource is a dependency property, so it’s easy enough to be notified when the property is changed to something else. You would want to use this in addition to code that you have, not instead of: In Window.Loaded (or similar) you can subscribe like so: var dpd = DependencyPropertyDescriptor.FromProperty(ItemsControl.ItemsSourceProperty, typeof(DataGrid)); if (dpd != null) { … Read more
There are a few options you can turn on to help you on your DataGrid object EnableColumnVirtualization = true EnableRowVirtualization = true These two are the main ones I think might help. Next try making your binding async ItemsSource=”{Binding MyStuff, IsAsync=True}” And lastly, I’ve heard that setting a maximum height and width can help even … Read more
You should use the datagrid method datagrid.ScrollIntoView(itemInRow); or datagrid.ScrollIntoView(itemInRow, column); this way provides no messing around finding the scroll viewer etc.
Or don’t bother with the primitives in the app.xaml file and do the following (my objects): <DataGrid Name=”WBdataGrid” AutoGenerateColumns=”False” ColumnHeaderHeight=”50″ > <DataGrid.ColumnHeaderStyle> <Style TargetType=”DataGridColumnHeader”> <Setter Property=”ContentTemplate”> <Setter.Value> <DataTemplate> <TextBlock TextWrapping=”Wrap” Text=”{Binding}”></TextBlock> </DataTemplate> </Setter.Value> </Setter> </Style> </DataGrid.ColumnHeaderStyle> <DataGrid.Columns> …
