BindingManagerBase.Count Property

When overridden in a derived class, gets the number of rows managed by the BindingManagerBase.

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

public abstract int Count { get; }

Property Value

Type: System.Int32
The number of rows managed by the BindingManagerBase.

Use the Count property to determine the last item in the list of rows maintained by the BindingManagerBase. To go to the last item, set the Position property to the Count property value minus 1.

The following code example shows four methods that set the Position property. The MoveNext method increments the property by 1. The MovePrevious method decrements the property by 1. The MoveFirst method sets the property to 0. The MoveLast method sets the property to the value of the Count property minus 1.


private void BindingManagerBase_CurrentChanged
(object sender, EventArgs e)
{
   // Print the new value of the current object.
   Console.Write("Current Changed: ");
   Console.WriteLine(((BindingManagerBase)sender).Current);
}

private void MoveNext()
{
   // Increment the Position property value by one.
   myBindingManagerBase.Position += 1;
}

private void MovePrevious()
{
   // Decrement the Position property value by one.
   myBindingManagerBase.Position -= 1;
}

private void MoveFirst()
{
   // Go to the first item in the list.
   myBindingManagerBase.Position = 0;
}

private void MoveLast()
{
   // Go to the last row in the list.
   myBindingManagerBase.Position = 
   myBindingManagerBase.Count - 1;
}
