範例

下列範例顯示如何將ExpandDirection屬性設定ExpandDirection為列舉成員。The following example shows how to set the ExpandDirection property to an ExpandDirection enumeration member.

<StackPanel>
  <RadioButton Name="ExpandDown" Margin="0,10,0,10" 
            IsChecked="True"
            Checked="ChangeExpandDirection"
            GroupName="ExpandDirectionProperty">
     Expand Down
  </RadioButton>
  <RadioButton Name="ExpandUp" Margin="0,0,0,10"
            Checked="ChangeExpandDirection"
            GroupName="ExpandDirectionProperty">
     Expand Up
  </RadioButton>
  <RadioButton Name="ExpandLeft" Margin="0,0,0,10"
            Checked="ChangeExpandDirection"
            GroupName="ExpandDirectionProperty">
    Expand Left
  </RadioButton>
  <RadioButton Name="ExpandRight" Margin="0,0,0,10"
            Checked="ChangeExpandDirection"
            GroupName="ExpandDirectionProperty">
    Expand Right
  </RadioButton>
</StackPanel>
private void ChangeExpandDirection(object sender, RoutedEventArgs e)
{
    if ((Boolean)ExpandDown.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Down;
    else if ((Boolean)ExpandUp.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Up;
    else if ((Boolean)ExpandLeft.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Left;
    else if ((Boolean)ExpandRight.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Right;

    //Expand myExpander so it is easier to see the effect of changing 
    //the ExpandDirection property for My Expander
    myExpander.IsExpanded = true;
}
Private Sub ChangeExpandDirection(ByVal Sender As Object, ByVal e As RoutedEventArgs)
    If (ExpandDown.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Down
    ElseIf (ExpandUp.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Up
    ElseIf (ExpandLeft.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Left
    ElseIf (ExpandRight.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Right
    End If

    'Expand myExpander so it is easier to see the effect of changing 
    'the ExpandDirection property for My Expander
    myExpander.IsExpanded = True
End Sub

備註

若要指定Expander控制項展開的方向, 請ExpandDirection將屬性設定為其中一個列舉成員。To specify the direction that an Expander control expands, set the ExpandDirection property to one of the enumeration members.
