问题 Ok I have a container that I have created two data templates for. Basically one template will show 5 textboxes with and objects data bound to them and the other template will show a button to add that particular object. I subclassed DataTemplateSelector and it works, but when I navigate through my records the Selector never gets called again. So how would I for the container to reselect it's template. The container is a StackPanel and I have already tried UpdateVisuals, InvalidateVisuals,

DataTemplate for a DataType - how to override this DataTemplate in a particular ListBox?

由 雨燕双飞 提交于 2019-12-05 21:36:29
I have created several DataTemplates for some of the DataTypes in my pet project. These data templates are really cool as they work like magic, magically transforming the look of the instances of the data types whenever and wherever they show up in the UI. Now I want to be able to change the DataTemplate for these DataTypes in one particular ListBox. Does this mean I have to stop relying on WPF automatically applying the data template to the data types and assign a x:Key to the DataTemplates and then apply the Template/ItemTemplate in the UI using that key? A ListBox contains items of various

问题 I'm currently implementing a listbox in WPF that will have 2 alternative layouts for its items: So far, I've done this using a DataTrigger to switch the ItemTemplate for the ListBox and it's working well: <ListBox ItemsSource="{Binding Runs}" SelectedItem="{Binding SelectedRun}"> <ListBox.Style> <Style TargetType="ListBox"> <Setter Property="ItemTemplate" Value="{StaticResource tileTemplate}"/> <Style.Triggers> <DataTrigger Binding="{Binding ShowRunsAsIcons}" Value="True"> <Setter Property=

LongListSelector and DataTemplateSelector

由 扶醉桌前 提交于 2019-12-04 20:06:27
问题 I'm using the LongListSelector to realize List or Grid display for my items. For this, I created a DataTemplateSelector and I change the LayoutMode property at runtime. This is working but there seems to be an issue with the DataTemplateSelector. If I initially launch the page, the DataTemplateSelector is called three times for my three items. When I navigate to another page (settings page to change the LayoutMode) and then back, the DataTemplateSelector is just called two items but there are

How to use DataTemplateSelector with ContentControl to display different controls based on the view-model?

由 你离开我真会死。 提交于 2019-12-01 13:46:36
I want to create a simple window that would display different controls ( SpinEdit or TextEdit ) based on the view-model that is selected. I have the code and logic behind it done already, what is left is displaying the control ( SpinEdit or TextEdit ) itself. XAML: <dx:DXWindow.Resources> <DataTemplate x:Key="DataTemplate_Value"> <dxe:SpinEdit Height="23" MinWidth="200" Width="Auto" Text="{Binding Path=Value, Mode=TwoWay}" Mask="{Binding Mask, Mode=OneWay}" MaxLength="{Binding Path=InputLength}" /> </DataTemplate> <DataTemplate x:Key="DataTemplate_Text"> <dxe:TextEdit Height="23" MinWidth="200
