[Solved] Add tooltip to RadRibbonView Collapse button

[Jeremiah]

Is there a way to add a tooltip to the collapse ribbon button? Preferably to have it say "Collapse the toolbar" when the ribbon is visible and "Show the toolbar" when it is collapsed.

Hello Jeremiah,

 You have to extract / get the default Style/Tempalte of the RadRibbonView and play with the MinimizeButton
(the green lines are new ones):

<telerik:RadRibbonToggleButton x:Name="MinimizeButton"
                                                                   ToolTipService.ToolTip="{Binding IsMinimized, RelativeSource={RelativeSource TemplatedParent} , Converter={StaticResource converter}}"
                                                                   IsChecked="{Binding IsMinimized, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}"
                                                                   IsEnabled="{TemplateBinding IsMinimizable}" Style="{TemplateBinding MinimizeButtonStyle}"
                                                                   Visibility="{TemplateBinding MinimizeButtonVisibility}"/>

 The converter looks like so:

public class BoolToStringConverter : IValueConverter
   {
       public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
          var isRibbonOpened = value as bool?;
          if (isRibbonOpened.HasValue)
          {
              if (isRibbonOpened == true)
              {
                  return "Show the RibbonView";
              }
              else
              {
                  return "Collapse the RibbonView";
              }
          }
           return "";
       }

You can find this realized in the attached solution. Greetings,
