CRM 2013: Differentiate various fields for update in a WFA plugin (C#)

Posted on by Hasibur Rahman

I have created a plugin (C# code dll) which I am using as step of a custom workflow. I want this workflow to kick in the case of

Update. But it is for multiple fields and the action would be different for each of them.

Now, I am wondering how in my C# code

protectedoverridevoidExecute(CodeActivityContextexecutionContext)

I could distinguish the different fields

No sure, I understand your question, but you are looking for which field your custom logic is fired, then you can check if field value is changed or not, you can utilize images in workflow (although not exposed explicitly but you can use them in your code).

Hi Hasibur,

If that information is not on the InputParameter of IWorkflowContext, You can use pre and post image and compare the field's info before and after.

@Bruno and @HIMBAP- thanks for your reply.

the information will be in one of the input parameters. Let me try to explain it

Say that the I have 2 input parameters X and Y. The workflow (which has the dll as step) will also get triggered at the change of X or Y. So, my question is in the C# code (the following method) - how can I determine if X or Y or both was changed

protected override void Execute(CodeActivityContextexecutionContext){

if (x changed)

if (y changed)

}

One way to find if the information has changed is comparing the value of the field on the preimage and the value of the field on postimage.

If postimage field A value is different from preimage field A value , that means that field has been updated.

Use can use Pre and Post images, and compare field value if ti is updated or not. Based on that you can follow your logic.
