Examples

The following code example demonstrates how to use the ResumeBinding method.

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=BindingContext [myDataSet, "Customers"];
      myBindingManager2.ResumeBinding();
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Source);
      MessageBox.Show(ex.Message);
   }
}

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

Remarks

SuspendBinding and ResumeBinding are two methods that allow the temporary suspension and resumption of in a simple data binding scenario. You would typically suspend data binding if the user must be allowed to make several edits to data fields before validation occurs. For example, if one field must be changed in accordance with a second, but where validating the first field would cause the second field to be in error.

Note

Using SuspendBinding prevents changes from being pushed into the data source until ResumeBinding is called but does not prevent changes in the data source from affecting the bound controls. Controls that use complex data binding, such as the DataGridView control, update their values based on change events such as the ListChanged event. Calling this method will not prevent these events from occurring. For this reason, SuspendBinding and ResumeBinding are designed for use with simple-bound controls, such as a TextBox. Alternatively, you can use these methods in a complex binding scenario if you suppress ListChanged events by setting the RaiseListChangedEvents property to false.
