WPF关闭子窗口时刷新父页面列表数据，WPF窗体间传参

Posted 2022-12-16 棉晗榜

父页面中的代码

//校对
private void Button_Click_3(object sender, RoutedEventArgs e)

	//选中的数据
	Gas_analysis? gas = this.dataGrid.SelectedItem as Gas_analysis;

    //打开子窗口，弹出
	WindowProofreadGasanalysis windowProofread = new WindowProofreadGasanalysis();
    
    //给子页面传值
	windowProofread.gas_Analysis = gas;
	
	windowProofread.Closed += WindowProofread_Closed;  //子窗口关闭后，执行
	windowProofread.ShowDialog();


private void WindowProofread_Closed(object? sender, EventArgs e)

	//关闭子窗口，刷新父页面列表
	DataGridLoadData(pager.PageIndex);

弹出的子页面，窗口

/// <summary>
///  校对
/// </summary>
public partial class WindowProofreadGasanalysis : Window

	public WindowProofreadGasanalysis()
	
		InitializeComponent();
	

	/// <summary>
	/// 被校对的数据
	/// </summary>
	public Gas_analysis gas_Analysis = null;
