1. Set radListView ViewType to DetailsView
2. Add a few ListViewDataItems
3. Run the app and inspect the control with the inspect.exe tool

You will see that the last item is not accessible by the tool. 

Note that if you hide the column headers (ShowColumnHeaders property) you will be able to access all ListViewDataItems.

System.NullReferenceException: 'Object reference not set to an instance of an object.' when removing items from the list:

 public Form1()
 {
     InitializeComponent();
     for (var i = 0; i < 30; i++)
     {
         var item = new ListViewDataItem();
         radListView2.Items.Insert(0, item);
         item[0] = i;
         item[1] = i;
         item[2] = i;
         item[3] = i;
     }
 }
private void radButton1_Click(object sender, EventArgs e)

    try
    {
        radListView2.BeginUpdate();

        foreach (var lvi in radListView2.Items.ToArray())

Just to report a little typo in RadListViewElement:

 

Protected Overrides Sub OnCurrecntItemChanged(args As ListViewItemEventArgs)

 

Thanks.

Release R2 2020 SP1

This problem is even reproducible in our Demo application >> Virtual Grid >> Web service example. You will notice that when you scroll to the bottom, the waiting indicator is not being animated when the DPI scaling is higher than 100%.

If you apply the same gif file in a PictureBox it gets animated when using 150% DPI scaling.

The issue can be reproduced if the control is not grouped when deleting the items in the data source.

Release R1 2020 (LIB 2019.3.1111)

Please refer to the attached sample project and follow the steps illustrated in the gif file.

Note: if the vertical  scrollbar is visible, the editor is activated as expected. 

Workaround:

Me.RadListView1.ItemSize = New Size(200, 30)
