Question

我在stackpanel内有边框（按钮）：

<StackPanel>
    <Border MouseLeftButtonUp="selectStudent" x:Name="button_0">
        <TextBlock >Anna</TextBlock>
    </Border>

    <Border MouseLeftButtonUp="selectStudent" x:Name="button_1">
        <TextBlock>Bart</TextBlock>
    </Border>
</StackPanel>

如果按下x:Name="button_0"，我想将Visibility x:Name="titel_0"更改为Visible，所有其他标题保持Collapsed

<TextBlock Visibility="Collapsed" x:Name="titel_0">Anna</TextBlock>
<TextBlock Visibility="Collapsed" x:Name="titel_1">Bart</TextBlock>

我将边框和标题放在一个数组中：

var buttons = new Array(2);
for (var i = 0; i < 2; i++) {
    buttons[i] = schermPage.content.findName('button_' + i);
}

var titels = new Array(2);
for (var i = 0; i < 2; i++) {
    titels[i] = schermPage.content.findName('titel_' + i);
}

如何开始编写selectStudent函数？

我试过

function selectStudent() {

if (buttons[0]) {
    titels[0].Visibility = 'Visible'
    }
}

但是如果我按下另一个边框，它仍会显示Anna

Answer 1

这是您的selectStudent函数的样子

void selectStudent(object sender, MouseButtonEventArgs e)
{
   string controlName = ((Border)sender).Name;
   //Write your if statement or switch case based on the controlName.
}

如何知道在Javascript-WPF-C中点击了哪个边框＃
