动态加载XAML

Question

我有一系列我加载的动态创建的vridviews。一切正常工作，除了扩展行详细信息时，我会收到一个错误“无法创建未知类型'{clr-namespace：emr.controls.hpi} hpidialogbutton'。命名空间emr.controls.hpi在执行程序中，我可以使用完全相同的XAML其他位置，它毫无问题。如果我评论“ HPI：hpidialogbutton ...”行，则行详细信息会毫无问题地扩展。

似乎在加载点，如果您直接做事，则缺少一些连接。

   private RadGridView BuildSectionGrid()
    {
      //This is defined here until a better solution is found
      string XAML = @"
          <my:RadGridView IsReadOnly=""False"">
            <my:RadGridView.Columns>
                <telerik:GridViewToggleRowDetailsColumn />
                <telerik:GridViewDataColumn Header=""Selected"" DataMemberBinding=""{Binding IsSelected}"" IsReadOnly=""False""/>
                <telerik:GridViewDataColumn Header=""Definition"" DataMemberBinding=""{Binding Definition}"" IsReadOnly=""True""/>
            </my:RadGridView.Columns>

            <my:RadGridView.RowDetailsTemplate>
                <DataTemplate>
                    <DockPanel Margin=""10"">
                        <Label Content=""Progress Note:"" DockPanel.Dock=""Left""/>
                        <hpi:HPIDialogButton Margin=""5 0 0 0"" DockPanel.Dock=""Right"" HPIText=""{Binding ElementName=NoteItemTextBox, Path=Text, Mode=TwoWay}""/>
                        <TextBox Name=""NoteItemTextBox"" Margin=""5 0 0 0"" DockPanel.Dock=""Left"" AcceptsReturn=""True"" TextWrapping=""Wrap"" Height=""100"" Text=""{Binding ProgressNote}""/>
                    </DockPanel>
                </DataTemplate>
            </my:RadGridView.RowDetailsTemplate>
        </my:RadGridView>
";


      //Load the XAML in again
      ParserContext Context = new ParserContext();
      Context.XmlnsDictionary.Add("", "http://schemas.microsoft.com/winfx/2006/xaml/presentation");
      Context.XmlnsDictionary.Add("x", "http://schemas.microsoft.com/winfx/2006/xaml");
      Context.XmlnsDictionary.Add("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006");
      Context.XmlnsDictionary.Add("telerik", "http://schemas.telerik.com/2008/xaml/presentation");
      Context.XmlnsDictionary.Add("hpi", "clr-namespace:EMR.Controls.HPI");
      Context.XmlnsDictionary.Add("my", "clr-namespace:EMR.Shared.Controls.WPF;assembly=EMR.Shared.Controls.WPF");
      return (RadGridView)XamlReader.Parse(XAML, Context);
    }

尝试在所有XMLN中指定汇编（您一方面错过）：

context.xmlnsdictionary.add（“ hpi”，“ clr-namespace：emr.controls.hpi; assembly = emr.controls.hpi”）;
