问题 I would like to know how to select a specific TabItem in a WPF TabControl. I tried these bellow but nothing work! MyTabControl.SelectedIndex = x MyTabControl.SelectedItem = MyTabItem MyTabControl.SelectedValue = MyTabItem MyTabItem.IsSelected = True 回答1: As @Chris says, any of the first three things should work and as @Phyxx says, it doesn't always really work.

问题 In wpf I setup a tab control that binds to a collection of objects each object has a data template with a data grid presenting the data. If I select a particular cell and put it into edit mode, leaving the grid by going to another tab this will cause the exception below to be thrown on returning the datagrid: 'DeferRefresh' is not allowed during an AddNew or EditItem transaction.
