abstract property int Count { int get(); };
public abstract int Count { get; }
member this.Count : int
Public MustOverride ReadOnly Property Count As Integer
Property Value
The number of rows managed by the BindingManagerBase.
Examples
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 );
}
void MoveNext()
{
// Increment the Position property value by one.
myBindingManagerBase->Position = myBindingManagerBase->Position + 1;
}
void MovePrevious()
{
// Decrement the Position property value by one.
myBindingManagerBase->Position = myBindingManagerBase->Position - 1;
}
void MoveFirst()
{
// Go to the first item in the list.
myBindingManagerBase->Position = 0;
}
void MoveLast()
{
// Go to the last row in the list.
myBindingManagerBase->Position = myBindingManagerBase->Count - 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;
}
Private Sub BindingManagerBase_CurrentChanged(sender As Object, e As EventArgs)
' Print the new value of the current object.
Console.Write("Current Changed: ")
Console.WriteLine(CType(sender, BindingManagerBase).Current)
End Sub
Private Sub MoveNext()
' Increment the Position property value by one.
myBindingManagerBase.Position += 1
End Sub
Private Sub MovePrevious()
' Decrement the Position property value by one.
myBindingManagerBase.Position -= 1
End Sub
Private Sub MoveFirst()
' Go to the first item in the list.
myBindingManagerBase.Position = 0
End Sub
Private Sub MoveLast()
' Go to the last row in the list.
myBindingManagerBase.Position = myBindingManagerBase.Count - 1
End Sub
Remarks
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.
