我有这个问题,所以在WPF设计期间我什么都看不见。
这是乞讨时的WPF代码:
<UserControl x:Class="VolumeControlInterface.VolumeControlInterface"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vtkVC="clr-namespace:VtkVolumeControl;assembly=VtkVolumeControl"
xmlns:local="clr-namespace:VolumeControlInterface"
Height="700" Width="700" Margin="5"
这是我的WPF代码在下面摆动:
<Grid DataContext="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}">
<vtkVC:VolumeRenderer Name="VolumeControl" Width="Auto" Height="Auto" Margin="5" Grid.Column="0"
LowerThresholdChanA="{Binding Path=BlackPoint0, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
UpperThresholdChanA="{Binding Path=WhitePoint0, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
LowerThresholdChanB="{Binding Path=BlackPoint1, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
UpperThresholdChanB="{Binding Path=WhitePoint1, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
LowerThresholdChanC="{Binding Path=BlackPoint2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
UpperThresholdChanC="{Binding Path=WhitePoint2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
LowerThresholdChanD="{Binding Path=BlackPoint3, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
UpperThresholdChanD="{Binding Path=WhitePoint3, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
IsChanASelected="{Binding Path=IsChanASelected, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
IsChanBSelected="{Binding Path=IsChanBSelected, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
IsChanCSelected="{Binding Path=IsChanCSelected, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
IsChanDSelected="{Binding Path=IsChanDSelected, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
DataSpacingZ="{Binding Path=DataSpacingZ, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
DataSpacingZMultiplier="{Binding Path=DataSpacingZMultiplier, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
FolderDirectory="{Binding Path=ZStackCacheDirectory, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
HardwareSettingsFile="{Binding Path=HardwareSettingsFile, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
TileIndex="{Binding Path=TileIndex, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
WellIndex="{Binding Path=WellIndex, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
TimePointIndex="{Binding Path=TimePointIndex, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
TotalSystemChannels="4"
Timepoints="1">
</vtkVC:VolumeRenderer>
</Grid>
此项目为VolumeControlInterface
,从另一个项目导入VtkVolumeControl.dll
作为参考。 VolumeRenderer
是VtkVolumeControl
中的一个类。 VtkVolumeControl
已成功构建,整个项目运行正常。我只是在设计VolumeControlInterface
时看不到任何内容,它说&#34;无法创建类型的实例&#39; VolumeRender&#39;&#34;
我尝试过:
删除VtkVolumeControl
,然后重新添加。不工作。
在构造函数中使用if (!System.ComponentModel.DesignerProperties.GetIsInDesignMode(this))
,无法正常工作。
我想知道这里发生了什么,以及如何让设计可见?
修改: 我正在使用VS2008,WINDOWS 7 64BIT
此外,每次构建vtkVolumeControl.dll
时,VolumeControlInterface
中的引用都会显示警告,说无法找到vtkVolumeControl.dll;但是如果我继续构建VolumeControlInterface
,那么它就不会有任何问题,而且它似乎设法找到了vtkVolumeControl.dll
。

您希望通过以下内容实现目标?
<Grid DataContext="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}">
因为你使用UserControl作为Binding,我认为这不是你想要的。
尝试以下操作来访问UserControl
<Grid DataContext="{Binding Path=DataContext, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}">
