We are
familiar with try, catch and finally. It has been around for many years. We
cannot ignore that at all as it plays a vital role in development.
Same is the
case when we write a client object model code for SharePoint 2010.
ExceptionHandlingScope
is a new class that has been introduced in SharePoint 2010 which allows us to
perform the same action.
Let’s say you
are working with managed client object model.
Here is a way
to get a context of ExceptionHandlingScope and to work with it.
ClientContext
ccontext = new ClientContext("site collection path");
ExceptionHandlingScope
exceptionscope = new ExceptionHandlingScope(ccontext);
using (exceptionscope.StartScope())
{
using (exceptionscope.StartTry())
{
// Code Block
}
using (exceptionscope.StartCatch())
{
//Code Block which handles the exception
}
using (exceptionscope.StartFinally())
{
//Code Block that always executes
}
}
Let’s say you
are working in ECMA client object model and would like to handle exception
function Example()
{
{
this.clientcontext = new
SP.ClientContext.get_current();
var clientScope = new
SP.ExceptionHandlingScope(this.clientcontext);
var startScope = clientScope.startScope();
var tryScope = clientScope.startTry();
// Code Block
tryScope.dispose();
var catchScope = clientScope.startCatch();
//Code Block which handles the exception
catchScope.dispose();
var finallyScope = clientScope.startFinally();
//Code Block that always executes
finallyScope.dispose();
startScope.dispose();
}
I hope this
will help developing smoother and robust client object model application.
