Server Side Code/ C# - getting field values

(0) ShareShare
ReportReport
Posted on by Community Member Microsoft Employee

I am new to D365 online. I have built a couple of basic solutions with out of the box features that just takes and stores information. I want to take the next step of taking that user input and manipulating it on the server side after the user submits/saves that data. 

I already know that i have to create a .dll in visual studios, make reference to the D365 sdk lib, and the format of the dll (ex. the class, IPlugin, and execute function).

My question is:

1. When a user saves a record, how do i read the information from the entity form submitted - for example, a string/value in a textbox from a entity form.  Also, if that value was a normal text file with a string in it, how do i get that information?

    Hi Merc

    You can write plugin with "Create" message. Below is the code

              IOrganizationService service = localContext.OrganizationService;

               IPluginExecutionContext context = localContext.PluginExecutionContext;

               if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)

               {

                   Entity entity = (Entity)context.InputParameters["Target"]; // read the information from the entity

                   if (entity.Attributes.Contains("emailaddress1") && entity.Attributes["emailaddress1"] != null)

                   {

                       string emailAddress = entity.Attributes["emailaddress1"].ToString(); // a string/value in a textbox from a entity

                   }

               }

    Hope it helps.

    Thanks,

    You are right, i want to do some type of processing when the information is submitted. The coding needs to be on the server side bc the amount of work that will be done will be heavy.

    Just for clarification - when you use the word "plugin", are you referring to server side code? how does Microsoft define "plugin"?

    Another question:

    is the MS site : docs.microsoft.com/.../mt676547(v%3dcrm.8) , the site i need to use to refer to information like the one you provided (ex. Entity entity = context.InputParameters["Target"];) ? or, is there another site?

    Hi merc718,

    Though I assume you want to do some processing on a field when it is submitted. You can write a plugin or even a JS code on the form onSave.

    But since I'm not aware how much of plugin/JS for D365 experience you have, I'll suggest the following -

    You can read the JS code - as Xrm.Page.getAttribute("fieldname").getValue(); in JS code that you can put onSave on the Form where user is entering data.

    OR

    You can read the field in Plugin code as

    Entity entity = context.InputParameters["Target"];

    String name = entity.getAttributeValue<String>("fieldname");

    and then do operations on the name in C#.

    Let me know if you have even more particular question depending on whether you are trying to do this in JS or in Plugin and I can suggest in a better way.

    Apart from this, you can even check out how Calculated Fields and Business Rules work. Maybe that'll also help you instead of code if your business logic is straight forward.
