BindingManagerBase.ResumeBinding 方法

当在派生类中被重写时，恢复数据绑定。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public MustOverride Sub ResumeBinding
用法
Dim instance As BindingManagerBase

instance.ResumeBinding

public abstract void ResumeBinding ()

public:
virtual void ResumeBinding () abstract

public abstract void ResumeBinding ()

public abstract function ResumeBinding ()

备注

SuspendBinding 和 ResumeBinding 是允许临时挂起和恢复数据绑定的两种方法。如果在进行验证之前必须允许用户对数据字段进行编辑，则通常会挂起数据绑定。例如，用户可能需要根据第二个字段来更改字段；否则，对第一个字段进行验证可能会导致第二个字段出现错误。

示例

Private Sub button4_Click(sender As Object, e As EventArgs)
   Try
      Dim myBindingManager2 As BindingManagerBase = BindingContext(myDataSet, "Customers")
      myBindingManager2.ResumeBinding()
   Catch ex As Exception
      MessageBox.Show(ex.Source.ToString())
      MessageBox.Show(ex.Message.ToString())
   End Try
End Sub 'button4_Click

private void button4_Click(object sender, EventArgs e)
{
   try
   {
      BindingManagerBase myBindingManager2=BindingContext [myDataSet, "Customers"];
      myBindingManager2.ResumeBinding();
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Source);
      MessageBox.Show(ex.Message);
   }
}

void button4_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
{
   try
   {
      BindingManagerBase^ myBindingManager2 = BindingContext[ myDataSet, "Customers" ];
      myBindingManager2->ResumeBinding();
   }
   catch ( Exception^ ex ) 
   {
      MessageBox::Show( ex->Source );
      MessageBox::Show( ex->Message );
   }
}

private void button4_Click(Object sender, EventArgs e)
{
    try {
        BindingManagerBase myBindingManager2 = 
            get_BindingContext().get_Item(myDataSet, "Customers");
        myBindingManager2.ResumeBinding();
    }
    catch (System.Exception ex) {
        MessageBox.Show(ex.get_Source());
        MessageBox.Show(ex.get_Message());
    }
} //button4_Click
