A VScrollBar control is a supporting control that is used to add vertical scrolling capability to a control that does not have built-in scrolling such as a container control. You do not need this control for the controls that already have built-in scrolling.
In this article, I will discuss how to create a VScrollBar control and apply vertical scrolling on Windows Forms controls that do not have a built-in scrolling feature. After that, I will discuss various properties and methods available for the VScrollBar control.

Creating a VScrollBar
We can create a VScrollBar control using a Forms designer at design-time or using the VScrollBar class in code at run-time (also known as dynamically).
To create a VScrollBar control at design-time, you simply drag and drop a VScrollBar control from Toolbox to a Form in Visual Studio. After you drag and drop a VScrollBar on a Form, the VScrollBar looks like Figure 1. Once a VScrollBar is on the Form, you can move it around and resize it using the mouse and set its properties and events.
Creating a VScrollBar control at run-time is merely a work of creating an instance of VScrollBar class, setting its properties and adding VScrollBar class to the Form controls.
The first step to create a dynamic VScrollBar is to create an instance of VScrollBar class. The following code snippet creates a VScrollBar control object.

The first step to create a dynamic VScrollBar is to create an instance of VScrollBar class. The following code snippet creates a VScrollBar control object.
- VScrollBar vScroller = newVScrollBar();
In the next step, you may set properties of a VScrollBar control. The following code snippet sets the height and width properties of a VScrollBar.
- vScroller.Height = 200;
- vScroller.Width = 30;
Once a VScrollBar control is ready with its properties, the next step is to add the VScrollBar control to the Form. To do so, we use Form.Controls.Add method. The following code snippet adds a VScrollBar control to the current Form.
- this.Controls.Add(vScroller);
Setting VScrollBar Properties
After you place a VScrollBar control on a Form, the next step is to set properties.
The easiest way to set properties is from the Properties Window. You can open Properties window by pressing F4 or right clicking on a control and selecting Properties menu item. The Properties window looks like Figure 2.

Hello Sir, I want to change the dimensions of image using scroll bar on web page in asp.net c# . Please help me about this

Cool stuff you got here! But the thing is, I am using a WebBrowser control (with built-in scrolling), and once the page is loaded I want to make it automatically scroll to a specific location.I tried some experiments with: WebBrowser wb; wb.AutoScrollOffset = new Point(Math.Abs(panel1.AutoScrollPosition.X), Math.Abs(CurrentPoint.Y)); //or simply - wb.AutoScrollOffset = new Point(0, 300); But none of them worked. So I was trying to find how to access the scroll bars within the WebBrowser control, but I simply can't find them. Is there any way I can access the WebBrowser VScrollBar? I only found the bool wb.ScrollBarsEnabled... I appreciate any suggestion!
