Overview
This article describes how to create a simple, custom user control-a smooth progress bar.
In the earlier version of the progress bar control, for example, the version provided in the Microsoft Windows Common Controls ActiveX control, you can see that the progress bar has two different views. You can set the Standard view or Smooth View by setting the Scrolling attribute.
The Smooth view provides an area for Smooth display of the progress. Standard tries to show that the progress is represented by a block.
The progress bar control provided in Visual C #. NET only supports Standard views.
The sample code in this article shows how to create a control with the following attributes:
Minimum. This attribute indicates the minimum value of the progress bar. The default value is 0. You cannot set this attribute to a negative value.
Maximum. This attribute indicates the maximum value of the progress bar. The default value is 100.
Value. This attribute indicates the current value of the progress bar. The value must be between Minimum and Maximum.
ProgressBarColor. This attribute indicates the color of the progress bar.
