ExpandDirection Enumeration
Specifies the direction in which an Expander control opens.
Assembly: PresentationFramework (in PresentationFramework.dll)
To specify the direction that an Expander control expands, set the ExpandDirection property to one of the enumeration members.
The following example shows how to set the ExpandDirection property to an ExpandDirection enumeration member. For the complete sample, see Expander Sample.
<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; }
