在后面的代码中从ResourceDictionary访问DataTemplate [英] Accessing DataTemplate from ResourceDictionary in code behind
问题描述
我正在尝试将供应商提供的VB解决方案转换为 C#
。我需要将数据模板从自定义ResourceDictionary XAML
加载到 c#
类中。我无法确定如何获取DataTemplate。我能够创建ResourceDictionary并加载 XAML
,但是从那里被困住了。这是我的 XAML
[EditorResources]。
I am trying to convert a vendor provided VB solution to C#
. I need to load a DataTemplate from a custom ResourceDictionary XAML
into a c#
class. I cannot determine how to get the DataTemplate. I am able to create a ResourceDictionary and load the XAML
but am stumped from there. Here is my XAML
.
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:PropertyEditing="clr-namespace:Microsoft.Windows.Design.PropertyEditing;assembly=Microsoft.Windows.Design.Interaction"
xmlns:Local="clr-namespace:MyControls.Design"
xmlns:my="clr-namespace:MyControls;assembly=MyControls"
x:Class="EditorResources">
<DataTemplate x:Key="TagBrowserInlineEditorTemplate">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBox Grid.Column="0" Text="{Binding StringValue}"/>
<PropertyEditing:EditModeSwitchButton Grid.Column="1"/>
</Grid>
</DataTemplate>
<DataTemplate x:Key="template">
<Border BorderThickness="2"
BorderBrush="Black">
<TextBlock Text="{Binding Path=value}" Padding="2" />
</Border>
</DataTemplate>
</ResourceDictionary>
这是我需要转换的VB代码:
Here is the VB code that I need to convert:
Imports System
Imports System.ComponentModel
Imports System.Windows
Imports Microsoft.Windows.Design.Metadata
Imports Microsoft.Windows.Design.PropertyEditing
Imports Microsoft.Win32
Public Class TagBrowserDialogPropertyValueEditor
Inherits DialogPropertyValueEditor
Private res As New EditorResources()
Public Sub New()
Me.InlineEditorTemplate = TryCast(res("TagBrowserInlineEditorTemplate"), DataTemplate)
End Sub
Public Overloads Overrides Sub ShowDialog(ByVal propertyValue As PropertyValue, ByVal commandSource As IInputElement)
Dim frmBrowseTagParameter As New OPCWPFDashboard.Design.FormBrowseTagParameter
If frmBrowseTagParameter Is Nothing Then
frmBrowseTagParameter = New OPCWPFDashboard.Design.FormBrowseTagParameter
End If
If frmBrowseTagParameter.ShowDialog = Forms.DialogResult.OK Then
propertyValue.StringValue = frmBrowseTagParameter.Final_Tag
End If
End Sub
End Class
推荐答案
据我了解, res
变量是从 ResourceDictionary
派生的类的实例。在这种情况下,您可以非常容易地获得数据模板:
As far as I understand, res
variable is the instance of the class derived from ResourceDictionary
. In this case you can get the data template very easy:
this.InlineEditorTemplate = res["TagBrowserInlineEditorTemplate"] as DataTemplate;
另请参见下面的文章以获取更完整的示例。
