CurrencyManager.SuspendBinding Method

Suspends data binding to prevents changes from updating the bound data source.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public override void SuspendBinding()

The SuspendBinding and ResumeBinding methods allow the temporary suspension and resumption of data binding in a simple binding scenario. You would typically suspend data binding if the user must 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.

NoteNote

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

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

private void button3_Click(object sender, EventArgs e)
{
   try
   {
      BindingManagerBase myBindingManager1=BindingContext [myDataSet, "Customers"];
      myBindingManager1.SuspendBinding();
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Source);
      MessageBox.Show(ex.Message);
   }
}
