Hello.

 I've been researching and made a code that could solve my problem of automatic visibility of the scroll bar in Telerik listView, Telerik ListControl and Windows listView

using System;
 
namespace TelerikWinFormsApp2
{
    public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        public RadForm1()
        {
            InitializeComponent();
  
            for (int i = 0; i < 50; i++)
            {
                radListView1.Items.Add("aa");
                radListControl1.Items.Add("aa");
                listView1.Items.Add("aa");
            }
 
            //Windows listView Mouse Events
            listView1.MouseEnter += new EventHandler(listView1_MouseEnter);
            listView1.MouseLeave += new EventHandler(listView1_MouseLeave);
 
            //Telerik listView Mouse Events
            radListView1.MouseEnter += new EventHandler(radListView1_MouseEnter);
            radListView1.MouseLeave += new EventHandler(radListView1_MouseLeave);
 
            //Telerik listControl Mouse Events
            radListControl1.MouseEnter += new EventHandler(radListControl1_MouseEnter);
            radListControl1.MouseLeave += new EventHandler(radListControl1_MouseLeave);
 
        }
 
        private void RadForm1_Load(object sender, EventArgs e)
        {
            //Windows ListView
            listView1.Scrollable = false;
 
            //Telerik ListView
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.FirstButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.SecondButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.ThumbElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.FillElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.Children[1].Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.BorderElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
 
            //Telerik ListControl
            this.radListControl1.ListElement.Scroller.Scrollbar.FirstButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.SecondButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.ThumbElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.FillElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.Children[1].Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.BorderElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
        }
 
        private void radListView1_MouseEnter(object sender, EventArgs e)
        {
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.FirstButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.SecondButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.ThumbElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.FillElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.Children[1].Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.BorderElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
        }
 
        private void radListView1_MouseLeave(object sender, EventArgs e)
        {
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.FirstButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.SecondButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;

            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.Children[1].Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListView1.ListViewElement.ViewElement.Scroller.Scrollbar.BorderElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
        }
 
        private void radListControl1_MouseEnter(object sender, EventArgs e)
        {
            this.radListControl1.ListElement.Scroller.Scrollbar.FirstButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListControl1.ListElement.Scroller.Scrollbar.SecondButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;

            this.radListControl1.ListElement.Scroller.Scrollbar.FillElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListControl1.ListElement.Scroller.Scrollbar.Children[1].Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radListControl1.ListElement.Scroller.Scrollbar.BorderElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
        }
 
        private void radListControl1_MouseLeave(object sender, EventArgs e)
        {
            this.radListControl1.ListElement.Scroller.Scrollbar.FirstButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.SecondButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.ThumbElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.FillElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.Children[1].Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            this.radListControl1.ListElement.Scroller.Scrollbar.BorderElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
        }
 
        private void listView1_MouseEnter(object sender, EventArgs e)
        {
            listView1.Scrollable = true;
        }
 
        private void listView1_MouseLeave(object sender, EventArgs e)
        {
            listView1.Scrollable = false;
        }
    }
         
}

 

I hope it helps.

 

Regards
Felipe.

Seems as though newer version of the RadListView control make this easier.

 

myListView.ListViewElement.VerticalScrollState = ScrollState.AlwaysHide;
myListView.ListViewElement.HorizontalScrollState = ScrollState.AlwaysHide;

Although I'd argue this should work as well but it doesn't unfortunately.  It is often hard to find which of the visual elements you need to set when dealing with WinForms Telerik controls.  

myListView.AutoScroll = false;

Hello Jared,

Our controls are using special scrollbar elements so that they can be themed. The inherited scrollbar are usually not used at all. Depending on the element hierarchy of the control one can access the RadScrollbarElements from the visual tree. For example, you can check the element hierarchy of the pdf viewer control, here: https://docs.telerik.com/devtools/winforms/controls/pdfviewer/structure/visual-structure. I can also suggest using the RadControlSpy tool to inspect the elements.

Let me know if you have other questions.

Regards,
Hristo
