Parameters

item
The item within the RasterImageList whose bounding rectangle you want to retrieve.

Return Value

A System.Drawing.Rectangle that represents the bounding rectangle of the specified RasterImageListItem.

The bounding rectangle returned by this method represents the entire item.

The bounding rectangle that this method returns could contain a negative position or could be outside the client rectangle of the control. The exact position of the item depends on the current size of the control as well as the current scroll position.

Example
 
Public Sub RasterImageList_GetItemRectangle(ByVal imageList As RasterImageList)
   ' Loop through all items
   For Each item As RasterImageListItem In imageList.Items
      ' Get the item bounding rectangle
      Dim rc As Rectangle = imageList.GetItemRectangle(item)
      ' If this rectangle is visible, highlight it
      If imageList.ClientRectangle.IntersectsWith(rc) Then
         ' Convert the rectangle to screen coordinates
         rc = imageList.RectangleToScreen(rc)
         ControlPaint.DrawReversibleFrame(rc, Color.Transparent, FrameStyle.Thick)
      End If
   Next item
End Sub
public void RasterImageList_GetItemRectangle(RasterImageList imageList)
{
   // Loop through all items
   foreach(RasterImageListItem item in imageList.Items)
   {
      // Get the item bounding rectangle
      Rectangle rc = imageList.GetItemRectangle(item);
      // If this rectangle is visible, highlight it
      if(imageList.ClientRectangle.IntersectsWith(rc))
      {
         // Convert the rectangle to screen coordinates
