ListBox.GetItemRectangle Method (Int32)
Returns the bounding rectangle for an item in the ListBox.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
If the item specified in the index parameter is not visible, the rectangle returned by this method will be outside the visible portion of the control. You can use this method to determine the size and position of an item within the list. To get the height of an item, especially a variable-height owner drawn list item, you can use the GetItemHeight method.
