Problems adding an ObjectDataProvider in resources

由 荒凉一梦 提交于 2021-01-28 06:01:04
问题 I'm setting up some things in XAML, but for some reason, I'm having an issue. I'm trying to add an ObjectDataProvider to my resources, but when I'm doing that, I get this warning on my resourcedictionnary saying i cannot have multiple items in a resourcedictionnary if they don't all have key attribute in it. So I add a key to resourcedictionnary, but then I have a problem on my dynamic resource in my contentcontrol. It says it cannot resolve "DefaultEmptyPane". Then I add a reference to the

问题 So I am pretty sure that up in the definition part I need to include something along the lines of: xmlns:s="clr-namespace:System.Collections.Generic;assembly=?????" but I just do not know what to put in place of the ???'s. What I want to do with the code is this: <UserControl.DataContext> <ObjectDataProvider MethodName="CreateNodes" ObjectType="{x:Type local:TreeViewModel}" > <ObjectDataProvider.MethodParameters> <s:List<T>> {Binding Nodes} </s:List<T>> </ObjectDataProvider.MethodParameters>

Is it possible to bind WPF Combobox.SelectedValue to multiple ObjectDataProviders?

问题 Trying to determine if it is possible to bind the SelectedValue of a ComboBox to the inputs of multiple ObjectDataProviders with XAMAL Bindings. I looked at MultiBinding but that appears to be grouping multiple controls together, not exactly what I'm looking to day. I'd like to be able to have the ComboBox (locations) change the TextBlock (deviance) which it does AND to call the ObjectDataProvider (CommentProvider) to update the TextBox (locationComments). This is fairly straightforward in a

问题 I am trying to bind an Enum to a ComboBox . I have seen a lot of people using an ObjectDataProvider but I cannot seem to access it. I have also noticed that some people are using it within a Window.Resources , rather than Page.Resources but I cannot find how it is used on Page.Resources . I have been searching for a solution for hours. What I have so far: XAML <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns

Instantiate and reuse instances of objects in XAML

问题 I want to instantiate objects in XAML, and reuse these instances. I think it should be simple but I'm stuck, I'm probably missing something obvious. Say I want to add Cats to different Rooms (Room has an ObservableCollection containing objects of type Cat). In the UserControl.Resources I create ObjectDataProviders: <ObjectDataProvider x:Key="Cat1" ObjectType="{x:Type local:Cat}"> <ObjectDataProvider.ConstructorParameters> <System:String>Tom</System:String> </ObjectDataProvider
