GridControl返回值

Question

我想從彈出窗體接收返回值。 彈出窗體上有一個gridControl需要插入父窗體gridControl中的值。

我把它叫做彈出的形式：

private void label14_Click(object sender, EventArgs e) 
    { 
     frmSelectInvoice selectInvoice = new frmSelectInvoice(); 
     selectInvoice.ShowDialog();    
    } 

這是彈出的形式來源：

public partial class frmSelectInvoice : DevExpress.XtraEditors.XtraForm 
{ 

    public ValinorEntities valinor; 
    public BindingSource src; 

    public frmSelectInvoice() 
    { 
     InitializeComponent(); 

     using (this.valinor = new ValinorEntities()) 
     { 
      this.valinor = new ValinorEntities(); 
      this.src = new BindingSource(valinor.invoices_head, null); 
      gridControl1.DataSource = src; 
      src.DataSource = valinor.invoices_head; 
     } 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 

     this.Close(); 
    } 
} 

應該是什麼，在彈出的形式返回值？

使用靜態類;

public static class MyClass 
{ 
    public static object myValue; 
} 


private void label14_Click(object sender, EventArgs e) 
{ 
    frmSelectInvoice selectInvoice = new frmSelectInvoice(); 
    selectInvoice.ShowDialog(); 
    //Get value before close 
    object value = MyClass.myValue; 
} 



public partial class frmSelectInvoice : DevExpress.XtraEditors.XtraForm 
{ 
    public ValinorEntities valinor; 
    public BindingSource src; 

    public frmSelectInvoice() 
    { 
     InitializeComponent(); 

     using (this.valinor = new ValinorEntities()) 
     { 
      this.valinor = new ValinorEntities(); 
      this.src = new BindingSource(valinor.invoices_head, null); 
      gridControl1.DataSource = src; 
      src.DataSource = valinor.invoices_head; 
     } 
    } 

private void button1_Click(object sender, EventArgs e) 
{ 
    //Set value after close 
    MyClass.myValue = "value"; 
    this.Close();  
} 

}
