Vertical orientation of Header Text

[schneeflocke]

Hi,

using Sample http://demos.telerik.com/silverlight/#Expander/FirstLook
If you choose left or right as expand direction the Header text of the expander is orientated in a vertical way.

How can I do the same?

The sample coding just use:

<telerik:RadExpander.Header>
    <TextBlock x:Name="expanderCaption" Text="Header" />
</telerik:RadExpander.Header>

Thanks

Stefan

Hi,

If you take a closer look at the demonstration project and open the Example.xaml.cs file you will find the following code:

private void OnDirectionsClick(object sender, RoutedEventArgs e)
{
    System.Windows.Controls.RadioButton radioButton = e.OriginalSource as System.Windows.Controls.RadioButton;
    if(radioButton != null)
    {
        Telerik.Windows.Controls.ExpandDirection expandDirection = (Telerik.Windows.Controls.ExpandDirection)System.Enum.Parse(typeof(Telerik.Windows.Controls.ExpandDirection), radioButton.Content.ToString(), true);
        this.radExpander.ExpandDirection = expandDirection;

        switch (expandDirection)
        {
            case Telerik.Windows.Controls.ExpandDirection.Down:
                this.radExpander.VerticalContentAlignment = System.Windows.VerticalAlignment.Top;
                this.radExpander.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
                break;
            case Telerik.Windows.Controls.ExpandDirection.Left:
                this.radExpander.VerticalContentAlignment = System.Windows.VerticalAlignment.Stretch;
                this.radExpander.HorizontalAlignment = System.Windows.HorizontalAlignment.Right;
                break;
            case Telerik.Windows.Controls.ExpandDirection.Right:
                this.radExpander.VerticalContentAlignment = System.Windows.VerticalAlignment.Stretch;
                this.radExpander.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
                break;
            case Telerik.Windows.Controls.ExpandDirection.Up:
                this.radExpander.VerticalContentAlignment = System.Windows.VerticalAlignment.Bottom;
                this.radExpander.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
                break;
            default:
                break;
        }
    }
}

This is the implementation of the Click event handler of all radio buttons in the ConfigurationPanel. And this code is used to rotate the header. Basically we set the ExpandDirection property of the RadExpander control and the control internally handles the rotation of the header.

Kind regards,

Thanks for your help. I missed the yellow marked line of code.

Thanks
