Make ID Field Viewable from form

This guide will show you how to access the id field of a table in dynamics so that you can use it within a table form. 

In this example, i will be adding the Opportunity ID to the Opportunity main view. The end product will look like this:

1. Create a new column on the table. (Nothing special just a text column)

2. Open the Form that you want to add the ID value to.

3. On the main form head to the to right and select events. 

4. Select "On Load", add a new event handler then, add a new library.

5. Select add new web resource. 

6. Add the JS code to get the ID value. (Update Xrm.Page.getAttribute("cr05b_opportunityid").setValue(id); to be the logical name of the column you created in step 1). 

function getOppertunityID() {

    let id = Xrm.Page.data.entity.getId(); //Get ID

    id = id.replace("{", "");  //Removes { from string

    id = id.replace("}", ""); //Removes } from string

    //Can be changed to the logical name of your column from step 1
    Xrm.Page.getAttribute("cr05b_opportunityid").setValue(id); 
}

7. Save and publish your web resource. 

8. Click on the dropdown for library and select the on that you just created. 

9. You then need to add the custom column to the form. 

10. Publish the From and the ID should appear on the form in dynamics. (To test this check the id with the one in the URL)
