Display a MessageBox in Silverlight
For people who tries to find the "MessageBox" class in Silverlight to display a message in a pop-up like we do in WinForms will have difficulty to find it because this doesn't work the same way. Because Silverlight runs in the browser, the message box is the one that is available in JavaScript: the "alert" method.
System.Windows.Browser.HtmlPage.Window.Alert("Your message goes here");
In the Window object (System.Windows.Browser.HtmlPage.Window) you will find some other things like "Prompt", "Navigate", "AttachEvent" and "Confirm". It shows how integrated with the browser and the JavaScript code Silverlight is, and this is a real good thing because you can easily make those 2 technologies talk together.
JavaScript AJAX wrapper for CRM 4.0

Hide and show items in a picklist in CRM 4.0
If you already worked with Microsoft Dyamics CRM 4.0, you know that almost everything you do with JavaScript is considered a "hack" because you manipulate the DOM of the pages by yourself. Because of this I decided to give you some help with differents helper methods I developped at my day job.
I'm currently working on a big development project involving CRM.
Those methods seems a lot more complicated than they has to be because we can't really hide and show items in picklists (HTML select). In HTML if you want to hide an "option" of a select, you need to remove it ! So when you want to show it back again you need to readd it to the list, and in addition to that, it will be placed at the end, not where he was before... so I created methods to help people to really hide and show CRM picklist items only by their value.
Hide a picklist item in CRM 4.0
function HidePickListItem(listID, value)
{
var objList = document.getElementById(listID);
// If the list has never been saved, save it now
if (objList.SavedList == null)
{
var arrListe = new Array();
for (var i=0; i<objList.options.length; i++)
{
arrListe[i] = new Object();
arrListe[i].value = objList.options[i].value;
arrListe[i].Libelle = objList.options[i].text;
arrListe[i].Visible = true;
}
objList.SavedList = arrListe;
}
for (var i=0; i<objList.SavedList.length; i++)
if (objList.SavedList[i].value == value)
objList.SavedList[i].Visible = false;
for (var i=objList.options.length - 1; i>=0; i--)
if (objList.options[i].value == value)
objList.options.remove(i);
}
Show a picklist item that has been hidden in CRM 4.0

null;
var indexInsertion = 0;
for (
var i=0; i<objList.SavedList.length; i++)
if (objList.SavedList[i].value == value)
objList.SavedList[i].Visible =
true;
// Keep the selected value so we can reselect it after
if (objList.selectedIndex > -1)
selValue = objList.options[objList.selectedIndex].value;
// Remove all the items in the list
for (var i=objList.options.length - 1; i>=0; i--)
objList.options.remove(i);
// Add the items that must be visible
for (var i=0; i<objList.SavedList.length; i++)
{
if (objList.SavedList[i].Visible)
{
var oOption = document.createElement('option');
oOption.text = objList.SavedList[i].Libelle;
oOption.value = objList.SavedList[i].value;
objList.options.add(oOption);
}
}
// Reselect the item that was selected
for (var i=0; i<objList.options.length; i++)
if (objList.options[i].value == selValue)
objList.selectedIndex = i;
}
}
Maximize the CRM child windows
If you already worked with Microsoft Dyamics CRM 4.0, you know that almost everything you do with JavaScript is considered a "hack" because you manipulate the DOM of the pages by yourself. Because of this I decided to give you some help with differents helper methods I developped at my day job.
I'm currently working on a big development project involving CRM. One of the client need was that all the windows appear fullscreen because their users are not familiar with mutliple levels of pop-up so by maximizing every window, you always have the feeling to be in the same window.

function MaximizeWindow()
{
window.moveTo(0, 0);

How to hide and show left navigation items in CRM 4.0

The first you need to do when you want to manipulate the left navigation section is to create a general function to get a reference to a navigation block. The reason is because each time you want to hide or show a block or nav item you need the DOM reference of the navigation block so instead of copying the code every time, you write a function and you call it everywhere.
Get the DOM reference to a left navigation block in CRM 4.0
function GetNavBlock(block)
{
var objBlockDetails = document.getElementById("_NA_Info");
var objBlockSales = document.getElementById("_NA_SFA");
var objBlockService = document.getElementById("_NA_CS");
var objBlockMarketing = document.getElementById("_NA_MA");
var objNavBlock = null;
if (objBlockDetails.innerText.substr(0, objBlockDetails.innerText.indexOf(":")).toLowerCase() == block.toLowerCase())
objNavBlock = objBlockDetails;
else if (objBlockSales.innerText.substr(0, objBlockSales.innerText.indexOf(":")).toLowerCase() == block.toLowerCase())
objNavBlock = objBlockSales;
else if (objBlockService.innerText.substr(0, objBlockService.innerText.indexOf(":")).toLowerCase() == block.toLowerCase())
objNavBlock = objBlockService;
else if (objBlockMarketing.innerText.substr(0, objBlockMarketing.innerText.indexOf(":")).toLowerCase() == block.toLowerCase())
objNavBlock = objBlockMarketing;
else
throw "The navigation block '" + block + "' doesn't exists.";
