Check if there is an article with the same title in the list of shared points and then show that information in the Infopath form

I have a requirement like this.

I have a SharePoint list called & # 39; Examdate & # 39; which stores different CoursNumber, Semester and ExamDate. Use an InfoPath form to enter the CoursNumber in the list.

Now they need to have a mechanism to find out if the user is adding a New Examination Date whose CoursNumber is already present. They do not want users to stop the addition process, but they want to show the ExamDate for this existing CoursNumber in the form. This should not happen on the Save button.

So, I was thinking of customizing the New article form by adding a button near the CoursNumber field, say "Verify existence", and verify if the CoursNumber and the semester exist for that number entered by the user. But I do not know how I can implement this.

What is the best and simplest way to do it?

c # – CareerCup (Bloomberg): check if the string is valid according to parentheses

Guard conditions

ArgumentNullException Normally it launches in the incorrect use of the API. It is not an exception of the end user, so I would not bother with an exception message.

throw new ArgumentNullException ("A string is required");

throw the new exception ArgumentNullException (nameof (s)); // maybe change the name of & # 39; s & # 39; to & # 39; entrance & # 39; or & # 39; value & # 39;

For him ArgumentException In the cases where you cast, I would also add the name of (parameter name) to the constructor. A decent error message is relevant here, so keep the message.

You have a guard in the blank space. I do not see this in the specification. Is this a requirement? If not, leave blanks as an open or closed support.

if (char.IsWhiteSpace (open) || char.IsWhiteSpace (close))

The next guard checks on duplicate records. An alternative policy is to ignore a record if it is already registered. This depends on whether you want your API to be prone to errors or to act as a sandbox for consumers.

if (openBrackets.Contains (open) || openBrackets.Contains (close))

I lack a guarding condition. I doubt open Y close it can be the same

if (open == close) // launch ..


You could replace some Yes Declarations with a ternary operator.

s = s ?? throw the new exception ArgumentNullException (nameof (s));
validator = validator ?? BracketValidator.CreateDefaultValidator ();

Redundant type declarations can be replaced by male. Unlike JavaScript, male It's fine in C #.

Stack openStack = new stack();

var openStack = new stack();

rest: check the values ​​of the custom fields of the project server when MSP_EpmProject_UserView is missing

Recently, I wanted to consult one of my custom field values ​​in the 2016 project server database, but I could not find MSP_EpmProject_UserView in my content database views!
After some searches, I found the March 2017 SharePoint update that solved this error, but after the installation of the March 2017 CU, the views of the project server are still being deleted.
Finally, I discovered that if you have several PWA sites in the same content database, ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡ ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡ ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡ Finally, I found out that if you have several PWA sites in the same content database, the user visits will not be filled
Now, how can I check the values ​​of my custom fields?

jquery – SharePoint REST API gets values ​​from check boxes, Get / Post

Using the SharePoint REST API, have a Bootstrap / HTML form that has approximately 20 questions, each with its own group of check boxes, and I am trying to obtain and publish the values ​​of the "checked" boxes. I can get one of the values ​​in the check box of a group to publish, but not all.

I'm also not sure how to have the check boxes checked in Get, for example, when a user opens the form for an existing record, they should check the correct check boxes.

What I have tried

var checkedV = $ (& # 39; input[name="q1error"]: marked & # 39;). map (function () {
returns $ (this) .value ();

& # 39; q1e & # 39 ;: $ (& # 39; input: check box[name="q1error"]: marked & # 39;). val ()
& # 39; q1e & # 39 ;: $ (& # 39; entrance[name="q1error"]& # 39;) .val (arrayValues)

Do you want to check the preview updates of the WP API?

Is there any way to check the previews of updates of already published publications through the WP API? For example, I am making updates to a publication that has already been published, I click on the preview button and it takes a URL similar to

Is there any way to access that content through the API?

I'm working on a WP project without a head and I need a way to show the preview in our custom interface. I can show the publications that are in Draft status, as well as the publications that have been published, by pressing the API. It is this last case of published publications that have additional updates that I can not seem to understand.

Any help is appreciated, thanks!
