WPF DataGrid EditItem异常

Question

I have a TabControl and add TabItem on TabControl with DataGrid . But if I double click on range crashes:

"EditItem" is not allowed for this view.

                    System.Windows.Controls.DataGrid dataGrid = new System.Windows.Controls.DataGrid();
 DataGridTextColumn textColumn = new DataGridTextColumn();
                    textColumn.Header = "ID";
                    textColumn.Binding = new Binding("ID");
                    dataGrid.Columns.Add(textColumn);
                    item.Content = dataGrid;
                    tabControl1.Items.Add(item);

When add Item:

list_datagrid[tabControl1.SelectedIndex].Items.Add(.list_item[tabControl1.SelectedIndex][i]);

Please tell me how to remove the error.

Answer 1

Set the ItemsSource of the DataGrid to the collection that DataGrid can use to generate the view that implements IEditableCollectionView . This interface has function EditItem() which let the editing happen.
