c# – 将TextBox名称参数从MainWindow.xaml传递给button_click函数

2024年1月15日 277次阅读

我正在制作一个使用Microsoft.Win32.OpenFileDialog的表单dlg = new Microsoft.Win32.OpenFileDialog();提供文件选择菜单.

我想使用相同的函数来更新输入文件的文本框和输出文件的文本框.

    <StackPanel Orientation="Horizontal" HorizontalAlignment="Left" Width="515" Height="96" VerticalAlignment="Top">
        <TextBlock Text="Input File:"  VerticalAlignment="Center"  />
        <TextBox x:Name="InputFileBox" Width ="213" VerticalAlignment="Center" TextChanged="InputFileBox_TextChanged" Height="17" Margin="0,39,0,40"  />
        <Button Content="Browse" Width="47" Margin="0,39,0,40" RenderTransformOrigin="1.599,0.714" Click="Browse_Click"/>
    </StackPanel>


    <StackPanel Orientation="Horizontal" HorizontalAlignment="Left" Width="515" Height="96" VerticalAlignment="Top">
        <TextBlock Text="Output File:"  VerticalAlignment="Center"  />
        <TextBox x:Name="OutputFileBox" Width ="213" VerticalAlignment="Center" TextChanged="OutputFileBox_TextChanged" Height="17" Margin="0,39,0,40"  />
        <Button Content="Browse2" Width="47" Margin="0,39,0,40" RenderTransformOrigin="1.599,0.714" Click="Browse_Click"/>
    </StackPanel>

所以我希望能够使用“BrowseClick”发送“InputFileBox”或“OutputFileBox”,这样我就不必拥有BrowseInputClick和BrowseOutputClick函数.

在Browse_Click函数中,我希望能够执行以下操作：

 private void Browse_Click(object sender, RoutedEventArgs e)
    {
        // Create OpenFileDialog 
        Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();


        // Display OpenFileDialog by calling ShowDialog method 
        Nullable<bool> result = dlg.ShowDialog();


        // Get the selected file name and display in a TextBox 
        if (result == true)
        {
            // Open document 
            string filename = dlg.FileName;

            // I don't know what to put here: input/outputTextBoxName = filename
        }

谢谢

最佳答案 在WPF中,您可以设置按钮的标记属性.

完成后,您可以使用单击处理程序获取标记属性

在XAML中添加Tag =“input”作为inputTextBox的属性之一,并将Tag =“output”添加到outputTextBox(例如：< TextBox x：Name =“inputTextBox”Tag =“input”/>)

var tag = (sender as Button).Tag;

然后：

if (tag == 'input')
    inputTextBox.Text = filename;
else outputTextBox.Text = filename;
