Specifies the direction the RasterImageList Control scrolls the displayed items.
public RasterImageListScrollStyle ScrollStyle { get; set; }
public:
property RasterImageListScrollStyle ScrollStyle {
RasterImageListScrollStyle get();
void set ( RasterImageListScrollStyle );
}
public:
property RasterImageListScrollStyle^ ScrollStyle
{
RasterImageListScrollStyle^ get()
void set(RasterImageListScrollStyle^ value)
}
A RasterImageListScrollStyle enumeration that specifies the direction the RasterImageList Control scrolls the displayed items. Default value is RasterImageListScrollStyle.Vertical.
This example fills a RasterImageList control with 10 items. It will then show the difference between vertical and horizontal scrolling styles.
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());
}
