    Hello together,

    I'm having some difficulties with a RadListView. My RadListView has 3 Columns: 1 for displaying an icon, 1 for a filename and the third for the author.
    My problem is, that only the first column is displayed and all the text columns are empty. I don't know why. Perhaps someone of you can help. Here is the code:

    ImageList MyImageList = new System.Windows.Forms.ImageList();
    MyImageList.ImageSize = new Size(16, 16);
    lst_Files.ViewType = Telerik.WinControls.UI.ListViewType.DetailsView;
    lst_Files.ShowGridLines = true;
    lst_Files.FullRowSelect = true;
    lst_Files.Columns.Add("Filename", "Filename");
    lst_Files.Columns.Add("Author", "Author");
    lst_Files.Columns[0].Width = 30;
    lst_Files.SmallImageList = MyImageList;
    foreach(Microsoft.SharePoint.SPFile file in files)
      for (int j = 0; j < MyImageList.Images.Count; j++)
        Telerik.WinControls.UI.ListViewDataItem item2 = new Telerik.WinControls.UI.ListViewDataItem();
        item2.Image = global::Test_SharePoint_DocumentList.Properties.Resources.icgen;
        item2.ImageIndex = j;
        item2.Tag = mysite.Url + "/" + file.Name;
        Telerik.WinControls.UI.ListViewDataItem item3 = new Telerik.WinControls.UI.ListViewDataItem();
        item3.Text = file.Name;
        item3.Value = file.Name;
        Telerik.WinControls.UI.ListViewDataItem item4 = new Telerik.WinControls.UI.ListViewDataItem();
        item4.Text = file.Author.ToString();
        item4.Value = file.Author.ToString();
        Telerik.WinControls.UI.ListViewSubDataItemCollection subcol = new Telerik.WinControls.UI.ListViewSubDataItemCollection(item2);

    And that's how it looks like in debug (see attachment):

    I have solved this issue.
    Here is my new code:

    var itemName = String.Format("listItem{0}", counter++);
    var values = new string[] { "", file.Name, file.Author.ToString() };
    var item2 = new Telerik.WinControls.UI.ListViewDataItem(itemName, values) { Image = global::Test_SharePoint_DocumentList.Properties.Resources.icgen, ImageIndex = j, Tag = mysite.Url + "/" + file.Name };
