Code is as given below:

            radListview.EnableSorting = true;

            radListview.EnableColumnSort = true;

            radListview.ViewType = ListViewType.DetailsView;
            radListview.Columns.Add("File Name");
            radListview.Columns.Add("Path");
            radListview.Columns.Add("Size (KB)");
            radListview.Columns.Add("Date");
            string[] files = Directory.GetFiles(@"D:\Codes\Images\orignal");
            foreach (string file in files)
            {
                FileInfo info = new FileInfo(file);
                ListViewDataItem item = new ListViewDataItem();
                radListview.Items.Add(item);
                item[0] = info.Name;
                item[1] = file;
                item[2] = (info.Length/1024);
                item[3] = info.LastWriteTime;
                var img = Image.FromFile("zip.png");
                item.Image = img;
            }

Hello, Hashim,

According to the provided screenshot, it seems that the image is big enough and it doesn't fit in the available space for the cell element in the DetailsView. In order to display the whole image, I can suggest you two options:

- Set the AllowArbitraryItemHeight property to true. Thus, the row's height will be adjusted to display the whole image:

- Subscribe to the CellFormatting event and set the CellElement.ImageLayout property to Zoom. Thus, the row's height will remain unchanged but the image will be shrunk to display the entire content: 

        private void radListView1_CellFormatting(object sender, ListViewCellFormattingEventArgs e)
        {
            e.CellElement.ImageLayout = ImageLayout.Zoom;
        }

 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
