The horizontal scrollbar appearance can be customized by using the HorizontalScrollBar.Style property. The ScrollBarStyleInfo contains all the settings that controls the appearance of the scrollbar.

Changing the Scrollbar thumb width

The size of the scrollbar thumb can be changed by using the ThumbWidth property of the corresponding Style property.

// To set the height of the horizontal scrollbar thumb.

NOTE

This width can be set maximum to the width and height of the vertical and horizontal scrollbars respectively.

Disabling the maximum and minimum buttons

The minimum and maximum arrow buttons of the scrollbar can be disabled by setting the EnableMaximumArrow and EnableMinimumArrow properties to false. The default value is true.

If you disable the max or min button, the scrollbar cannot be scrolled using those buttons.

//Disable the maximum and minimum arrows of the vertical scrollbar. 
this.sfScrollFrame1.VerticalScrollBar.EnableMaximumArrow = false;
this.sfScrollFrame1.VerticalScrollBar.EnableMinimumArrow = false;

//Disable the maximum and minimum arrows of the horizontal scrollbar. 
this.sfScrollFrame1.HorizontalScrollBar.EnableMaximumArrow = false;
this.sfScrollFrame1.HorizontalScrollBar.EnableMinimumArrow = false;

The color of the disabled arrow button can also be specified by using ArrowButtonDisabledBackColor and ArrowButtonDisabledForeColor of the corresponding scrollbar.

//Set the arrow button disabled back color
this.sfScrollFrame1.VerticalScrollBar.Style.ArrowButtonDisabledBackColor = Color.Silver;
this.sfScrollFrame1.HorizontalScrollBar.Style.ArrowButtonDisabledBackColor = Color.Silver;

//Sets the arrow button disabled fore color
this.sfScrollFrame1.VerticalScrollBar.Style.ArrowButtonDisabledForeColor = Color.Gray;
this.sfScrollFrame1.HorizontalScrollBar.Style.ArrowButtonDisabledForeColor = Color.Gray;
