Example

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
 
public void RasterImageList_ScrollStyle(RasterImageList imageList) 
{ 
   // Clear out any items in the image list 
   imageList.Items.Clear(); 
 
   // Create 20 items 
   for (int i = 0; i < 20; i++) 
   { 
      // Load the image 
      int index = i + 1; 
      RasterImageListItem item = new RasterImageListItem(null, 1, "Item" + index.ToString()); 
 
      // Select every otehr item 
      if ((i % 2) == 0) 
         item.Selected = true; 
 
      // Add the item to the image list 
      imageList.Items.Add(item); 
   } 
 
   // Set vertical scrolling style 
   imageList.ScrollStyle = RasterImageListScrollStyle.Vertical; 
 
   // Scroll a couple of lines down 
   imageList.ScrollItems(2); 
 
   // Show the scroll parameters of the control 
   ShowScrollParameters(imageList); 
 
   // Switch to horizontal scrolling style 
   imageList.ScrollStyle = RasterImageListScrollStyle.Horizontal; 
 
   // Show the scroll parameters of the control 
   ShowScrollParameters(imageList); 
} 
 
 
private void ShowScrollParameters(RasterImageList imageList) 
{ 
   StringBuilder sb = new StringBuilder(); 
   sb.AppendFormat("Full Visible Rows: {0}{1}", imageList.FullVisibleRows, Environment.NewLine); 
   sb.AppendFormat("Visible Rows: {0}{1}", imageList.VisibleRows, Environment.NewLine); 
   sb.AppendFormat("Full Visible Columns: {0}{1}", imageList.FullVisibleColumns, Environment.NewLine); 
   sb.AppendFormat("Visible Columns:{0}{1}", imageList.VisibleColumns, Environment.NewLine); 
   sb.AppendFormat("TotalRows: {0}{1}", imageList.TotalRows, Environment.NewLine); 
   sb.AppendFormat("TotalColumns: {0}{1}", imageList.TotalColumns, Environment.NewLine); 
   sb.AppendFormat("TopIndex: {0}{1}", imageList.TopIndex, Environment.NewLine); 
   MessageBox.Show(sb.ToString()); 
}
