C# 如何在用户选择第一个网格后自动生成下一个网格

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comboBox 1中选择了一个选项，该方法将自动生成另一个网格（包含comboBox 2），依此类推

下面是我当前拥有的代码，现在我想创建一个事件驱动方法，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">
            <Label Content="Test Component 2:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
            <ComboBox x:Name="testCompCB2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Margin="134,4,0,0"/>

            <ComboBox x:Name="testCompCB6" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Margin="134,10,0,-3"/>
        </Grid>
        <Grid x:Name="comp7" Margin="0,328,230,100" Visibility="Hidden">
            <Label Content="Test Component 7:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
            <ComboBox x:Name="testCompCB7" HorizontalAlignment="Left" VerticalAlignment="Top" Width="207" IsEditable="True" Tag="Test Component" Margin="134,5,0,0"/>
        </Grid>

        </Grid>

嗨，对于那些对此感兴趣的人，我使用以下简单的过程编码方法解决了这个问题

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"/>

你能描述一下你的场景和用例吗？通常我会使用

ListBox

并创建一个

DataTemplate

作为

ListBox.itemtplate

来创建这样一个视图。嗨，我需要做的是每个类别的用户，这个类别可以有多个测试。所以对于a类，用户可以选择添加测试1、测试2、测试3等等。所以，当用户在测试1中选择了组合框1中的项目时，我需要自动生成包含组合框2的测试2。嗯，听起来有点奇怪，或者我不理解您的用例。实现一个AddItem视图（一个

列表框

，其中包含活动的选定测试和两个

按钮

，以便从

列表框

添加和删除测试，不是更好吗？您好，我解决了问题alr。非常感谢！

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

        }

    }
