custom horizontal scrollbar

Hi Martin,

I think you are looking for our scrollbar tray feature.  Please see the "SyntaxEditor / User Interface Features / Editor View Features / Scrolling" topic in the documentation that comes with the product, and the last several sections within that.  It shows how you can add any UI element on the sides of the scrollbars.

That looks promising. However i can not access the control within the DataTemplate.

<DataTemplate x:Key="SyntaxEditorScrollBarTray">
        <controls:SectionComboBox x:Name="sectionComboBox" MinWidth="50" />
</DataTemplate>

I can retrieve this template and assign it to my editor, it is visible:

var db = new ResourceDictionary();
            db.Source = new Uri("StatNeth.Blaise.IDE.Base;component/Resources.xaml", UriKind.RelativeOrAbsolute);
            var dt = db["SyntaxEditorScrollBarTray"] as DataTemplate;
            this.ScrollBarTrayRightTemplate = dt;

But i can not access the sectionComboBox in any way, e.g. 

            _sectionCombo = _editor.Template.FindName("sectionComboBox", _editor) as Base.Controls.SectionComboBox;

Maybe you can help me, how can i access a named control in this syntaxeditor?

Thank you in advance:)

Hi Martin,

You could probably search down the visual tree.  We have helper methods in our VisualTreeHelperExtended class like this that can assist:

var sectionComboBox = VisualTreeHelperExtended.GetFirstDescendant(syntaxEditor, typeof(SectionComboBox)) as SectionComboBox;

Hi

In the Load event i track down the element

_sectionComboBox = ActiproSoftware.Windows.Media.VisualTreeHelperExtended.GetFirstDescendant(this, typeof(IDE.Base.Controls.SectionComboBox)) as IDE.Base.Controls.SectionComboBox;

which correctly gets the control. Still a bit doubtfull about the timing, but for now it works.

Thanks.
