Nice work, this saved me a considerable amount of time.
I made a couple of tweaks to help in portability between projects. Specifically, I didn't want to have a Server Control that required the Javascript and CSS files to be copied into each project sepearately.
BTW - I also ported the code to VB, so the detail below will not match perfectly 
To address this I put the files the Javascript files (from the Sourceforge project) into subdirectories alongside the server control. Each of these is set to be an "Embedded Resource" at compile time.
Next up I modified the AssemblyInfo.vb file to include these resource as follows: -
<br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.Calendar.js", "text/javascript")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.Calendar-Setup.js", "text/javascript")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.Calendar-EN.js", "text/javascript")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-Blue.css", "text/css")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-Brown.css", "text/css")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-Green.css", "text/css")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-System.css", "text/css")><br />
Finally, I modified the the script registration code so that it uses WebResources rather than explicit include statements. Similarly, I moved the code into the OnLoad event of the control so that everything is placed on the page in a logical sequence and is there when required.
The OnLoad event code looks like this...
<br />
Private Sub JSCalendar_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
<br />
' Register the JAVASCRIPT blocks<br />
If (Not Me.Page.ClientScript.IsClientScriptIncludeRegistered("JSCalendarScript")) Then<br />
Dim scriptLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), "Aardware.ControlLibrary.Calendar.js")<br />
Me.Page.ClientScript.RegisterClientScriptInclude("JSCalendarScript", scriptLocation)<br />
End If<br />
If (Not Me.Page.ClientScript.IsClientScriptIncludeRegistered("JSCalendarLang")) Then<br />
Dim resourceName As String = String.Format("Aardware.ControlLibrary.Calendar-{0}.js", Me.Language)<br />
Dim scriptLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), resourceName)<br />
Me.Page.ClientScript.RegisterClientScriptInclude("JSCalendarLang", scriptLocation)<br />
End If<br />
If (Not Me.Page.ClientScript.IsClientScriptIncludeRegistered("JSCalendarSetup")) Then<br />
Dim scriptLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), "Aardware.ControlLibrary.Calendar-Setup.js")<br />
Me.Page.ClientScript.RegisterClientScriptInclude("JSCalendarSetup", scriptLocation)<br />
End If<br />
<br />
' Register the CSS theme with the page<br />
If (Not Me.Page.ClientScript.IsClientScriptBlockRegistered("JSCalendarTheme")) Then<br />
Dim resourceName As String = String.Format("Aardware.ControlLibrary.{0}.css", Me.Theme)<br />
Dim includeTemplate As String = "<link rel='stylesheet' text='text/css' href='{0}' />"<br />
Dim includeLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), resourceName)<br />
Dim include As LiteralControl = New LiteralControl(String.Format(includeTemplate, includeLocation))<br />
Me.Page.Header.Controls.Add(include)<br />
Me.Page.ClientScript.RegisterClientScriptBlock(GetType(DateField), "JSCalendarTheme", "")<br />
End If<br />
<br />
End Sub 'DateField_Load<br />
This removes the need for the ScriptsBasePath property and make portability easier - I only need to reference the library now, rather than worry about the scripts and style sheets.
The solutions works nicely for me and I can live the the small loss of flexibility in not being able to modify the Javascript and CSS files on a project be project basis.

Hi,
I seem to have a Flat Calendar working on my page
asp:Label ID="Container" runat="server" Width="200">
asp:HiddenField ID="TextBox1" runat="server" />
asp:Label ID="Label1" runat="server" Text="">
function dateChanged(calendar) {
// Beware that this function is called even if the end-user only
// changed the month/year. In order to determine if a date was
// clicked you can use the dateClicked property of the calendar:
if (calendar.dateClicked) {
var MyD = calendar.date;
var MyTxt = document.getElementById("TextBox1");
MyTxt.value = MyD.print("%d/%m/%Y");
Label1.innerHTML = MyD.print("%d/%m/%Y");
//window.location = "Default.aspx";
}
};
Calendar.setup({
//displayArea : "TextBox1", //*
daFormat : "%d/%m/%Y",
//date : "09/08/2006",
showsTime : false,
weekNumbers : false,
range : [2006, 2009],
flat : "Container",
flatCallback : dateChanged,
//button : "MyButton", //*
step : 1
});
MyCode behind is
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
DateTime MyStartDate = DateTime.Now.AddDays(2);
Label1.Text = MyStartDate.ToShortDateString();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = TextBox1.Value.ToString();
}
But i want to be able to call a postback when the user changes the date
- if (calendar.dateClicked)
do post back here!!!
And i want to be able to dynamically load the date + 2 days on page load
and then each time the page post back to hold the changed date
I hope that makes sense
Can anyone help Please Please!!!!!!!!

This contorl is nice but it is missing a designer class. A designer class is what VS.Net calls when you drop it on a web form. To get rid of the "Error Creating Control" add this class:
class JSCalendarDesigner : System.Web.UI.Design.ControlDesigner
{
public override string GetDesignTimeHtml()
{
StringWriter sw = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(sw);
HtmlGenericControl gc = new HtmlGenericControl();
gc.InnerText = "[JSCalendar]";
gc.RenderControl(tw);
return sw.ToString();
}
}
then add an attribute like this to the main class:
[DefaultProperty("Value"),
ToolboxData("<{0}:JSCalendar runat=server></{0}:JSCalendar>"),
Designer("CalendarControl.JSCalendarDesigner")]
recomplie then drop it on a form and it will look like a regular control.

Hi there -
In general, I am happy with this control. However i in the HTML design surface in 2005 (and i thin also in 2003) i get
"Error Rendering Control"
An unhandled exception has occured. Object refernce not set to an instance of an object"
This doesnt affect the actual use of the control at runtime, only at design time. Any idea why this might be?

Hi Hazem,
Nice work, saved me some time. I've converted your source code to VB.NET (see below) and added a couple of tweaks. I prefer to use System.IO.StringWriter when concatenating strings as the code looks less cluttered and easier to debug IMO (also means you don't need to be using the VisualBasic namespace when coding C# )
The only other notable alteration is when setting the ScriptPath property, where I simply added a check to ensure there's a trailing slash so the tags are rendered properly. Caught me out on the first execution  .
Anyway, here goes;
Imports System.IO
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.ComponentModel
<DefaultProperty("Value"), ToolboxData("<{0}:calendarselect runat=server></{0}:calendarselect>")> _
Public Class CalendarSelect

Private myImageURL As String = String.Empty
Private myScriptsPath As String = String.Empty
Private myDateFormat As String = "dd/MM/yyyy"
Private myTheme As String = "calendar-Blue"
Private myLanguage As String = "en"
Private imgCalendar As New Image
#Region " Property Declarations "
<Bindable(True), Category("Appearance"), DefaultValue("en")> _
Public Property Language() As String
Get
Return myLanguage
End Get
Set(ByVal Value As String)
myLanguage = Value
End Set
End Property
<Bindable(True), Category("Appearance"), DefaultValue("calendar-Blue")> _
Public Property Theme() As String

Return myTheme
End Get
Set(ByVal Value As String)
myTheme = Value
End Set
End Property
<Bindable(True), Category("Appearance"), DefaultValue("dd/MM/yyyy")> _
Public Property DateFormat() As String
Get

End Get
Set(ByVal Value As String)
myDateFormat = Value
End Set
End Property

End Set
End Property

myImageURL = Value
End Set
End Property
#End Region

I have found that the control can't be stand alone in the web forms. It has to be in either placeholders or div tags. Is this a bug with JSCalendar or the dll?
Thanks

|

I tried it and it's working standalone... please give me more details about the error ..
thanks

It's not an error. If you drag and drop the control anywhere in the web form the image shows up at the top of the page and the textbox shows up where the control used to be. Looks like position properties of JScalendar are inherited by textbox but not by the image. Does the image have to be an web form image to inherit the properties?
Thanks

It could be better if you have told how to setup the javascript file paths and image file paths.
Power your brain
