radTreeView disable scrollbar

[Michael]

Hello,

I want to disable the scrollbars of a radTreeView. Could you please help me to do this. I have already tried to set to false the Visible and/or the Enable properties of VerticalScroll and/or HScrollBar, but the scrollbars are still visible.
Thanks.

Best regards,
Michael

Hello Michael,

That is because the visibility of the scrollbars in RadTreeView is updated on layout.
You could handle the VisibleChanged event of the scrollbars and in the handler set the visibility to false like:

public Form1()
        {
            InitializeComponent();

            this.radTreeView1.HScrollBar.VisibleChanged += new EventHandler(HScrollBar_VisibleChanged);
        }

        void HScrollBar_VisibleChanged(object sender, EventArgs e)
        {
            this.radTreeView1.HScrollBar.Visible = false;
        }

Hope this helps.

I am using version 2012.2.726.40 and    this.radTreeView1.HScrollBar doesn't have an event called VisibleChanged  . How can i  do this?

Hello Berkant Oral,

Thank you for writing.

To hide the horizontal scrollbar, you need to subscribe to the RadPropertyChanged event of the HScrollBar and set the Visibility property to collapsed. Here is a sample snippet:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        this.radTreeView1.HScrollBar.Visibility = ElementVisibility.Collapsed;
        this.radTreeView1.HScrollBar.RadPropertyChanged += new RadPropertyChangedEventHandler(HScrollBar_RadPropertyChanged);
    }


    void HScrollBar_RadPropertyChanged(object sender, RadPropertyChangedEventArgs e)
    {
        if (e.Property == RadItem.VisibilityProperty)
        {
            this.radTreeView1.HScrollBar.Visibility = ElementVisibility.Collapsed;
        }
    }
}

Attached is a sample project that demonstrates the above snippet.

I hope you find my answer useful. Let me know if you have further queries.

Kind regards,
