我想问一下如何自动生成包含标签和组合框的网格。我想要的是，一旦用户在组合框 1 中选择了一个选项，该方法将自动生成另一个网格（包含组合框 2）等等。

下面是我目前拥有的代码，现在我很想创建一个事件驱动的方法来在当前组合框中调用 IsSelected 后显示下一个网格。

 <Grid x:Name="comp1" Margin="0,84,230,345">
            <Label Content="Test Component 1:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
            <ComboBox x:Name="testCompCB1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Margin="134,4,0,0"/>
        </Grid>
        <Grid x:Name="comp2" Margin="0,127,230,302" Visibility="Hidden">

            <ComboBox x:Name="testCompCB2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Margin="134,4,0,0"/>

嗨，对于那些对此感兴趣的人，我使用以下幼稚的程序编码方式解决了它。

对于 xaml：

<StackPanel x:Name="testCompList" HorizontalAlignment="Left" Height="274" Margin="10,92,0,0" VerticalAlignment="Top" Width="361">
            <Canvas x:Name="comp1" Margin="0,0,8,0" Height="26">
                <Label Content="Test Component 1:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp2" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 2:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp3" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 3:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp3" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp4" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 4:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp4" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp5" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 5:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp5" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp6" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 6:" HorizontalAlignment="Left" VerticalAlignment="Top" Canvas.Top="3"/>
                <ComboBox x:Name="testComp6" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp7" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 7:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp7" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp8" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 8:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp8" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5" DropDownClosed="addNewRow"/>
            </Canvas>
            <Canvas x:Name="comp9" Margin="0,0,8,0" Height="26" Visibility="Hidden">
                <Label Content="Test Component 9:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                <ComboBox x:Name="testComp9" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Canvas.Left="134" Canvas.Top="5"/>
            </Canvas>
        </StackPanel>

对于后面的代码：

int i = 1;        
private void addNewRow(object sender, EventArgs e) //all will invoke this generic     method to display the visibility of the next
    {
        ComboBox selectedTest = (ComboBox)sender;
        Canvas thisRow = (Canvas)selectedTest.Parent;
        int index =Int32.Parse(thisRow.Name.Substring(thisRow.Name.Length-1, 1));
        if (thisRow is Canvas && index==i) //needs to ensure that only the previous canvas can invoke the next canvas once selection is done
        {
            i++;
            Canvas newRow = (Canvas)this.FindName("comp" + i);
            newRow.Visibility = Visibility.Visible;
            //add the test Component to a data structure like a list or something

        }

    }
