Retrieve the current CRM version

The CRM SDK DLLs can easily connect to different CRM versions, for example the CRM 2013 DLLs can be used also with CRM 2011/2015 environments.
Depending the version some messages (like the ExecuteMultipleRequest) are not available, the following function returns an enumerator with the current CRM version.

public enum CRMVersion
{
    Unknown,
    CRM2011,
    CRM2011UR12PLUS,
    CRM2013,
    CRM2013SP1,
    CRM2015
}

public CRMVersion GetCRMVersion(IOrganizationService service)
{
    RetrieveVersionRequest versionRequest = new RetrieveVersionRequest();
    RetrieveVersionResponse versionResponse = (RetrieveVersionResponse)service.Execute(versionRequest);

    string version = versionResponse.Version;
    if (version.StartsWith("5"))
    {
        try
        {
            int buildNumber = Convert.ToInt32(version.Substring(version.LastIndexOf(".") + 1));
            if (buildNumber > 3000) { return CRMVersion.CRM2011UR12PLUS; }
        }
        catch { }
        return CRMVersion.CRM2011;
    }
    if (version.StartsWith("6.0")) { return CRMVersion.CRM2013; }
    if (version.StartsWith("6.1")) { return CRMVersion.CRM2013SP1; }
    if (version.StartsWith("7")) { return CRMVersion.CRM2015; }
    return CRMVersion.Unknown;
}

How to bind a function to the Sub-Grid refresh event

A common customization requested by customers is to execute some logic when a Sub-Grid is refreshed. Unfortunately the Xrm Object Model doesn't provide a method to bind a function to the refresh event.
To implement this functionality is necessary to use unsupported JavaScript code, paying attention when a new rollup is released.
The following code is compatible with UR12/Polaris update that introduced cross-browser support for CRM 2011.

function AddEventToGridRefresh(gridName, functionToCall) {
   // retrieve the subgrid
   var grid = document.getElementById(gridName);
   // if the subgrid still not available we try again after 1 second
   if (grid == null) {
       setTimeout(function () {AddEventToGridRefresh(gridName, functionToCall);}, 1000);
       return;
   }
   // add the function to the onRefresh event
   grid.control.add_onRefresh(functionToCall);
}

Is possible to use the AddEventToGridRefresh function in two different ways. Assuming to attach the following function:

// function used in this example
function AdviseUser() {
   alert("Sub-Grid refreshed");
}

The function can be called directly passing the parameters inside the dialog box


or inside another JavaScript function:

function OnLoad() {
   AddEventToGridRefresh('accountContactsGrid', AdviseUser);
}

The first parameter is a string and quotation marks are necessary, the second parameter is the name of the function and must be written without quotation marks.

Get current user's full name with a synchronous call

An AJAX request can be made also synchronous, this can be useful when we want to make a simple and fast request inside CRM 2011.
In this example we will retrieve the full name of the current user and set the value to a custom field called "new_userfullname".
