Developing Data Navigation Control (VCR) For Windows Forms

Introduction

Under windows forms data bound forms are very common. Many forms have buttons for data navigation such as next, previous, last and first. Such navigation control is commonly called as VCR control as it resembles VCR buttons. This sample code shows how to develop such a VCR custom control that you can use in your projects.

Source Code

The source code contains two files:
  • VCRControl.vb that represents VCR custom control
  • Form1.vb that represents sample client for VCR control
The VCR custom control exposes a property called DataSource that needs to be set to CurrencyManager class of your form. Once that is done you can use navigation buttons to navigate through records. The control also shows current record in the form of "x of y".
