WPF MVVM: Setting DataContext of Tab Views

由 假装没事ソ 提交于 2019-12-04 06:00:26
问题 I have experienced a weird binding behavior that is described here. I did a lot of troubleshooting and I came to the conclusion that the most likely problem lies at how I set the DataContext of each of the tab's view. I have a TabControl whose ItemsSource is bound to a list of ViewModels . MainView: <TabControl ItemsSource="{Binding TabList}"> <TabControl.Resources> <DataTemplate DataType="{x:Type vm:Tab1ViewModel}"> <v:Tab1 /> </DataTemplate> </TabControl.Resources> ... </TabControl>

Data Error 26 with DataTemplate and ItemTemplate

由 痞子三分冷 提交于 2019-12-04 04:53:45
问题 I have a TabControl with a single specific tab and a collection bound to a collection of VMs, using a different user control. To do this I use a CompositeCollection and DataTemplates defined in the control's resources, selecting correct user control based on the VM type (acting as ContentTemplate). I also set an ItemTemplate to define the tab item's name with binding, but it's not defined in the resource as I guess would conflict with the "ContentTemplate" ones. It works fine, but I see the

问题 This question already has answers here : Closed 6 years ago . Possible Duplicate: How to make ListBox editable when bound to a List<string>? I'm trying to set a two-binding between a List named "ListStr" object and a ListBox WPF control. Besides I want the items to be editable, so I added a DataTemplate with TextBoxes expecting that it would modify the ListStr items straight away via TextBoxes. But when I'm attempting to edit one of them, it doesn't work... Any Idea ? PS: I've tried to add

Scroll a new item in a ItemsControl into view

由 左心房为你撑大大i 提交于 2019-12-04 01:05:03
问题 I have an ItemsControl that is databound to a ObservableCollection . I have this method in the code behind which adds a new model to the list.

The effect of this code is to scroll to a point slightly above the new item. How would I know what the new
