                        Control Customization Sample

                        

===============================================================================



/////////////////////////////////////////////////////////////////////////////

Use:



The Control Customization sample demonstrates how to customize the Windows Forms 

controls.



In this sample, there're 4 examples:

 

1. Multiple Column ComboBox.

   Demonstrates how to display multiple columns of data in the dropdown of a ComboBox.

2. ListBox Items With Different ToolTips.

   Demonstrates how to display different tooltips on each items of the ListBox.

3. Numeric-only TextBox.

   Demonstrates how to make a TextBox only accepts numbers.

4. A Round Button.

   Demonstrates how to create a Button with irregular shape.

   



/////////////////////////////////////////////////////////////////////////////

Code Logic:



1. Example 1: "Multiple Column ComboBox".



   1). Create a DataTable with several columns and rows of data;

   2). Data bind the ComboBox control to the DataTable;

   3). Enable the owner draw on ComboBox by setting the DrawMode property to 

       DrawMode.OwnerDrawFixed;

   4). Handle the DrawItem event on the ComboBox;

   5). In the DrawItem event handler, compute the bounds for each column and 

       draw corresponding value for each column on its bounds.



2. Example 2: "ListBox Items With Different ToolTips".



   1). Add some items to the ListBox control;

   2). Handle the MouseMove event on the ListBox control;

   3). Call the ListBox.IndexFromPoint method to retrieve the item index at 

       where the mouse hovers;

   4). If the mouse is over the items, call ToolTip.SetToolTip method to display

       a tooltip for the individual item.

   

3. Example 3: "Numeric-only TextBox".



   The make a TextBox accepts only numbers, we can handle the TextBox.KeyPress 

   event, in the event handler use char.IsNumber method to filter the input keys.

   

4. Example 4: "A Round Button".



   The key point of creating a round button is changing its Region property.
