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()
{
InitializeComponent();
GetCheckboxes();//Keep all the checkbox
in List
in the Load itself
}
#endregion
#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.
/// <summary>
/// Set the Availability on the Form, with the Provided Timings
/// </summary>
/// <param name="selectedTimings">Provided timings comes from the DB
in the form 11,12,13....37
/// Where 11 refers to Monday Morning, 12 Tuesday Morning, etc
/// Here 1, 2, 3 is for Morning, Afternoon and Evening respectively, and for weekdays
/// 1,2,3,4,5,6,7 where 1 is for Monday, Tuesday, Wednesday, Thrusday, Friday, Saturday and Sunday respectively
/// So if we want Monday Morning, we can can denote it as 11, similarly for Saturday Evening we can write 36, etc
/// </param>
public void SetAvailibility(string selectedTimings)
{
foreach (CheckBox chk
in checkBoxList)
{
chk.IsChecked = false;
}
if (!String.IsNullOrEmpty(selectedTimings))
{
string[] selectedString = selectedTimings.Split(',');
foreach (string selected
in selectedString)
{
foreach (CheckBox chk
in checkBoxList)
{
if (chk.Tag.ToString() == selected)
{
chk.IsChecked = true;
}
}
}
}
}
/// <summary>
/// Gets the Availibility from the selected checkboxes
/// </summary>
/// <returns>String
in the format of 11,12,13...41,42...31,32...37</returns>
public string GetAvailibility()
{
string selectedText = string.Empty;
foreach (CheckBox chk
in GetCheckboxes())
{
if (chk.IsChecked == true)
{
selectedText = chk.Tag.ToString() + "," + selectedText;
}
}
return selectedText;
}
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
preferredTimeControl.SetAvailibility("11,12,13,16,23,22");
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
xmlns:controls="clr-namespace:PreferredTimeControlApp"
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"></controls:PreferredTimeControl>
</Border>
</Grid>
And
in the code behind you can just include this code:
private void InitializeControl()
{
preferredTimeControl.SetAvailibility("11,12,13,16,23,22");
}
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.
Download Source Code.
