A simple preferred time control, where you can select the day of the week and the time of the day.

Here I am going to show you a simple preferred time control, where you can select the day of the week and the time of the day. This can be used in lots of place where you may need to display the users preferred times. Sample screenshot is attached below.


This control is developed using Silverlight 3 and VS2008, I am also attaching the source code with this post. This is a very basic example. You can download and customize if further for your requirement if you want.

I am trying to explain in few words how this control works and what are the different ways in which you can customize it further.

File: PreferredTimeControl.xaml, in this file I have just hardcoded the controls and their positions which you can see in the screenshot above. In this example, to change the start day of the week and time, you will have to go and change the design in XAML file, its not controlled by your properties or implementation classes. You can also customize it to change the start day of the week, Language, Display format, styles, etc, etc.

File: PreferredTimeControl.xaml.cs, In this control using the code below, first I am taking all the checkbox from my form and store it in the Global Variable, which I can use across my page.

List<CheckBox> checkBoxList;

#region Constructor
public PreferredTimeControl()
    GetCheckboxes();//Keep all the checkbox in List in the Load itself

#region Helper Methods
private List<CheckBox> GetCheckboxes()
    //Get all the CheckBoxes in the Form
    checkBoxList = new List<CheckBox>();
    foreach (UIElement element in LayoutRoot.Children)
        if (element.GetType().ToString() == "System.Windows.Controls.CheckBox")
            checkBoxList.Add(element as CheckBox);

    return checkBoxList;

Then I am exposing the two methods which you can use in the container form to get and set the values in this controls.

/// <span class="code-SummaryComment"><summary>

In my example I am using the matrix format for Day and Time, for example Monday=1, Tuesday=2, Wednesday=3, Thursday = 4, Friday = 5, Saturday = 6, Sunday=7. And Morning = 1, Afternoon =2, Evening = 3. So if I want to represent Morning-Monday I will have to represent it as 11, Afternoon-Tuesday as 22, Morning-Wednesday as 13, etc. And in the other way to set the values in the control I am passing the values in the control in the same format as


So this will set the checkbox value for Morning-Monday, Morning-Tuesday, Morning-Wednesday, Morning-Saturday, Afternoon of Tuesday and Afternoon of Wednesday.

To implement this control, first I have to import this control in xmlns namespace as


and finally put in your page wherever you want,

<Grid x:Name="LayoutRoot" Style="{StaticResource LayoutRootGridStyle}">
    <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}">
        <controls:PreferredTimeControl x:Name="preferredTimeControl">

And in the code behind you can just include this code:

private void InitializeControl()

And you are ready to go. For more details you can refer to my code attached.

I know there can be even simpler and better way to do this. Let me know if any other ideas.

Sorry, Guys Still I have used Silverlight 3 and VS2008, as from the system I am uploading this is still not upgraded, but still you can use the same code with Silverlight 4 and VS2010 without any changes. May be just it will ask you to upgrade your project which will take care of rest. You can also refer to a better formatted version of this post here.

Download Source Code.
