Silverlight Vertical and Horizontal Scroller

This free Scroller control allows Silverlight 2 content be scrolled automatically and also through user control via the mouse.

This Silverlight only Scroller Control is easy to implement on your Silverlight driven website and is also customizable to provide a visual feel suitable for any site design.

To use the Scroller control you will need to add a reference to Liquid.dll in your project.


How to Use the Scroller Control

To use the Scroller on your Silverlight page:

<UserControl x:Class="Scroller.Page"

            <liquid:Scroller Direction="-1,0">
                <liquidRichText:TextBlockPlus FontSize="25" Shadow="Normal" Text="This is a horizontal scroller, but it doesn't have to scroll from right-to-left. By specifying the Direction property you can scroll content in any direction!" />
            </liquid:Scroller>
        </Border>
        <Border Grid.Row="1" BorderThickness="1" BorderBrush="#aaaaaa" CornerRadius="4" Margin="4">
            <Border.Background>
                <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
                    <GradientStop Color="#e0e0e0" Offset="0.0" />
                    <GradientStop Color="#f8f8f8" Offset="0.5" />
                    <GradientStop Color="#efefef" Offset="1.0" />
                </LinearGradientBrush>
            </Border.Background>
            <liquid:Scroller Direction="1,0" EnableUserControl="True">
                <liquidRichText:TextBlockPlus FontSize="35" Foreground="Red" Shadow="Normal" Text="You can also allow the user to interact with the scrolling with the mouse. Click and drag the content to affect the scrolling!" />
            </liquid:Scroller>
        </Border>
    </Grid>
</UserControl>


Here we have two scrollers, both scrolling a TextBlock Plus.  In reality you can specify anything as content, so you could scroll and image or even a Rich Text document.  The top scroller is a non-interactive right-to-left scroller, the lower one is a left-to-right scroller and you can interact with the scrolling using the mouse.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace Scroller
{
    public partial class Page : UserControl
    {
        public Page()
        {
            InitializeComponent();
        }
    }
}


The Direction property controls how fast and in what direction the content is scrolled and the EnableUserControl property determines whether the user can interact with the scrolling.

dan posted on Color selector bugs?

Hi Ron,


Unfortunately not in the current version, Transparent will render as White.  I'll see if we can make the colour visual configurable for individual color cells in the next version.


Thanks!

Hi I have an enhancement to suggest to the color selector.


My application actually uses 3 color selectors all with custom colors enabled and what I've found is that all 3 of these use the same custom color palette object (ColorSelector.Custom). Is it possible to make it so that these all use a different custom color palette ie they have their own member Custom list variables instead of a static one for the entire ColorSelector class?


I've tried to define my own List of uints for each of the color selectors but the currently selected color doesn't update properly so I assume there is something else going on underneath that I don't have access to.


Thanks again!

Dose Liquid support Silverlight 4.0 beta?

Dan,

I am working with your Color Selector control and Custom Colors which is a very nice implementation!


However, I have a challenge which I am unsure how to handle:


How do I detect whether a particular color already exists in the Pallette?  For instance: #FF5E60B8 which was selected from the CustomColors functionality...  I don't want to add the color to the CustomColors if it already exists in the standard pallette...  I want to just select that color using the "SELECTED" property...


Thanks in advance!

Ron


Hi,


I have updated the demo as the current one was built against an older version of Visual Studio.  You can download the updated demo from the same link as before.

Thanks!

Hi,


This I did see occur once and having looked at the code have made a slight change to the closed event handler that hopefully fixes this.  This fix will be available in the next version of the controls library.


Thanks!
