invalidating a contract - Itemupdating spitemeventproperties properties

Basically the raised event was performing data validation for the List Item being updated.

This was totally perplexing to me and for the longest time I thought that it had something to do with the Datasheet view being asynchronus and losing its context everytime an item was edited. To String()); He suggested to instead use a different method to retrieve the values: string delivery Qty = Convert. After Properties[IFN_Updated Delivery Qty]); I then had to update some code to accommodate and convert the strings to the ints that I had originally wanted and everything worked in both the Edit Form and Datasheet view! Lesson Learned: Correct me if I’m wrong, I guess for some reason MSFT didn’t implement the .

Then this morning, I had a friend look at the line of code that was returning the null problem: int delivery Qty = int. To String() method for people that wanted to retrieve information from the properties bag when an Item Updating event is fired from the Datasheet view.

Given the asynchronous nature of the Item Added, if you change the data content, you are not 100% sure that the form displayed to the user include the new data and thus avoid conflicts backup.

For this we must add the synchronization parameter to our xml definition.

Step 2Enter site URL and select Deploy as a farm solution and click Finish. Step 4Select event receiver and enter the title of the event receiver. Step 5Select List Item Events in type of event receiver and select the Document Library option from the event source. Here, I have created the Employee Documents library to add and maintain documents and also created an Employee Document Log list to log the changes happening to the library.

Then select an events as in the following and click Finish. Here I'm trying to update a Share Point list based on file changes happening to a separate Share Point Document Library. An Employee Documents Document Library has the following columns: Step 9Build and deploy the solution. Go to the Employee Documents Document Library and add a new document.

Indeed, all asynchronous event can be defined as synchronous!

This will allow us to pre-fill the data in our forms before the user does not grasp anything!

It’s very easy to spot if a function is synchronous or asynchronous based on its name. Before Properties[«Field Name »] And yes, three possibilities depending on the actions and the synchronicity of the eventcan contain either the new value, or the old value, or nothing at all!
