Getting Started

Set up Project

https://github.com/AhashSritharan/Xrm-Ex/assets/63707488/750cd578-e174-43b0-8783-149599db3da5

Deployment

https://github.com/AhashSritharan/Xrm-Ex/assets/63707488/34e2642d-0d73-4964-a5c5-6c035a474773

To get started with XrmEx, use the Template below. Add XrmEx.js from your node_modules to your Dynamics 365 form as a library. Execute the method YourNamespace.ContactFunctions.OnLoad in your form and pass the executionContext to that function. Happy coding!

Note: Although built with TypeScript, this library is distributed as compiled javascript and its TypeScript declaration. This means it can be used in any javascript file by just referencing the XrmEx.d.ts file. For it to work, you have to add the XrmEx.js file to the Form in Dynamics 365.

Use the following Starter Template for your JavaScript:

/// <reference path="node_modules/xrm-ex/src/XrmEx.d.ts" />
var YourNamespace = YourNamespace || {};
YourNamespace.Contact = YourNamespace.Contact || {};
(function (Self) { //Only properties assigned to the Self object will be exposed to the global scope
    class Fields {
        Firstname = new XrmEx.Class.TextField("firstname");
        Customer = new XrmEx.Class.LookupField("parentcustomerid");
        DoNotEmail = new XrmEx.Class.BooleanField("donotemail");
        Birthday = new XrmEx.Class.DateField("birthdate");
        PreferredContactMethod = new XrmEx.Class.OptionsetField(
            "preferredcontactmethodcode",
            {
                Any: 1,
                Email: 2,
                Phone: 3,
                Fax: 4,
                Mail: 5,
            }
        );
    }
    class Tabs {
        General = new XrmEx.Class.Tab("tab1", {
            Section1: new XrmEx.Class.Section("section1"),
            Section2: new XrmEx.Class.Section("section2"),
        });
        Details = new XrmEx.Class.Tab("tab2", {
            Section1: new XrmEx.Class.Section("section1"),
            Section2: new XrmEx.Class.Section("section2"),
        });
    }
    class Grids {
        ContactSubgrid = new XrmEx.Class.GridControl("Test");
    }
    /**@type {Xrm.FormContext}*/ var formContext;
    /**@type {Fields}*/ var fields;
    /**@type {Tabs}*/ var tabs;
    /**@type {Grids}*/ var grids;

    /**
     * @param {Xrm.FormContext | Xrm.Events.EventContext} executionContext 
     */
    Self.OnLoad = async function OnLoad(executionContext) {
        await Init(executionContext); //Ensures XrmEx is only accessed after the OnLoad Event
        try {
            fields.Firstname.Value = "Joe";
            fields.Firstname.setVisible(true).setDisabled(true).setRequired(false);
            await XrmEx.openAlertDialog("Success", "Xrm works.");
        } catch (error) {
            console.error(error);
            await XrmEx.openAlertDialog("Error", `Error in ${XrmEx.getFunctionName()}\n` + error.message);
        }
    };
    /**
     * @param {Xrm.FormContext | Xrm.Events.EventContext} executionContext 
     */
    async function Init(executionContext) {
        if (!XrmEx) {
            let errorMessage = "XrmEx is not loaded. Please make sure you have XrmEx.js loaded in your form.";
            console.error(errorMessage);
            await Xrm.Navigation.openAlertDialog({ title: "Error", text: errorMessage, });
            return;
        }
        XrmEx.Form.executionContext = executionContext;
        formContext = XrmEx.Form.formContext;
        fields = new Fields();
        tabs = new Tabs();
        grids = new Grids();
        parent.window.XrmEx = XrmEx;
    }

Leverage the power of Dynamics 365 Client API with less code and fewer errors. Get started with XrmEx today!

Why Use the XrmEx Library?

When developing for Dynamics 365, efficiency, clarity, and maintainability are paramount. The XrmEx library is designed to streamline your coding experience, making it more intuitive and less error-prone. Let's delve into some examples to illustrate the transformative power of XrmEx:

1. Event Handling

Without XrmEx:

formContext.data.entity.addOnSave(sample);
Copy

With XrmEx:

XrmEx.Form.addOnSave([sample]);
Copy

The XrmEx approach is more concise and offers a clearer intent, especially when registering multiple functions.

2. Field Changes and Events

Without XrmEx:

let firstname = formContext.getAttribute("firstname");
let lastname = formContext.getAttribute("lastname");
firstname.addOnChange(sample);
firstname.fireOnChange();
lastname.fireOnChange();
Copy

With XrmEx:

XrmEx.Form.addOnChange(
  [fields.Firstname, fields.Lastname],
  [sample],
  true //fireOnChange
);
Copy

With XrmEx, you can handle multiple fields and events in a single line, making the code cleaner and more maintainable.

3. Form Types and Field Requirements

Without XrmEx:

if (formContext.ui.getFormType() != 2) return;
let firstname = formContext.getAttribute("firstname");
if (!firstname.getValue()) {
    firstname.setRequiredLevel("required");
    firstname.controls.forEach((c) =>
      c.setNotification("This property is required", "uniqueId")
    );
}
Copy

With XrmEx:

if (XrmEx.Form.IsNotUpdate) return;
if (!fields.Firstname.Value)
    fields.Firstname.setRequired(true).setNotification(
      "This property is required","uniqueId");
Copy

XrmEx provides intuitive methods that simplify common tasks, like checking form types or setting field requirements. You don't have to use the redundant forEach anymore.

4. Data Retrieval and Setting

Without XrmEx:

let ownerid = formContext.getAttribute("ownerid");
let lastname = formContext.getAttribute("lastname");
if (ownerid.getValue() && !lastname.getValue()) {
    let user = await Xrm.WebApi.retrieveRecord(
      ownerid.getValue()[0].entityType,
      ownerid.getValue()[0].id,
      "?$select=lastname"
    );
    lastname.setValue(user.lastname);
}
Copy

With XrmEx:

if (fields.Owner.Value && !fields.Lastname.Value) {
    let user = await fields.Owner.retrieve("?$select=lastname");//Returns null if empty
    fields.Lastname.Value = user.lastname;
    fields.Lastname.setValue(user.lastname);
}
Copy

XrmEx abstracts away the complexities of data retrieval, making it more straightforward and readable.

5. Alert Dialogs in Dynamics 365

Without XrmEx:

await Xrm.Navigation.openAlertDialog({ text: `Error in ${XrmEx.getFunctionName()}\n` + error.message, title: "Error" }, { height: 120, width: 260 });
Copy

This method requires manual sizing and is more verbose, making it less efficient for dynamic content.

With XrmEx:

await XrmEx.openAlertDialog("Error", `Error in ${XrmEx.getFunctionName()}\n` + error.message);
Copy

The XrmEx approach automatically sizes the dialog based on content to avoid scrolling, offering a simplified and concise method.

Advanced Features

1. Lookup Filters

Without XrmEx:

let filterFunction = function filterFunction(executionContext) {
    let formContext = executionContext.getFormContext();
    let customer = formContext.getAttribute("parentcustomerid");
    customer.controls.forEach((c) => {
        c.addCustomFilter(
            `<filter>
                <condition attribute="lastname" operator="like" value="%Test%" />
            </filter>`
        );
    });
};
let customer = formContext.getAttribute("parentcustomerid");
customer.controls.forEach((c) => c.addPreSearch(filterFunction));
customer.controls.forEach((c) => c.removePreSearch(filterFunction));
Copy

With XrmEx:

fields.Customer.addPreFilterToLookup(
    `<filter>
        <condition attribute="lastname" operator="like" value="%Test%" />
    </filter>`
);
fields.Customer.clearPreFilterFromLookup(); //Removes all filter added with addPreFilterToLookup or addPreFilterToLookupAdvanced
Copy

2. Advanced Lookup Filter

Special with XrmEx: Supports entire FetchXml including Link-Entity!

await fields.Customer.addPreFilterToLookupAdvanced(
    "contact",//entityname
    "contactid",//entity unique identifier name
    `<fetch>
        <entity name="contact">
            <filter>
                <condition attribute="lastname" operator="like" value="%Test%" />
            </filter>
            <link-entity name="account" from="accountid" to="parentcustomerid">
                <filter>
                        <condition attribute="address1_country" operator="eq" value="Switzerland" />
                </filter>
            </link-entity>
        </entity>
    </fetch>`
);
Copy

3. Execute Bound Action

Without XrmEx:

class TestActionContactRequest {
Amount: 0;
Account: null;
getMetadata() {
    return {
    boundParameter: "entity",
    operationType: 0,
    operationName: "theia_TestActionContact",
    parameterTypes: {
        Amount: {
        typeName: "Edm.Int32",
        structuralProperty: 1,
        },
        Account: {
        typeName: "mscrm.account",
        structuralProperty: 5,
        },
        entity: {
        typeName: "mscrm.contact",
        structuralProperty: 5,
        },
    },
    };
}
}
let testActionContactRequest = new TestActionContactRequest();
testActionContactRequest.Amount = 5;
testActionContactRequest.Account = customer.getValue()[0];
testActionContactRequest["entity"] =
formContext.data.entity.getEntityReference();
let response = await Xrm.WebApi.online.execute(testActionContactRequest)
    .then(function (response) {
        if (response.ok) {
            return response.json().catch(() => {
                return response;
            });
        }
    })
    .then((responseBody) => responseBody);
console.log(response);
Copy

With XrmEx:

let response2 = await XrmEx.executeAction(
    "theia_TestActionContact",{
        Amount: 5,
        Account: fields.Customer.Value[0]
    },
    XrmEx.Form.entityReference
);
console.log(response2);
Copy

4. Retrieve EnvironmentVariableValue

Without XrmEx:

class EnvironmentVariableRequest {
DefinitionSchemaName: "";
constructor(definitionSchemaName) {
    this.DefinitionSchemaName = definitionSchemaName;
}
getMetadata() {
    return {
    boundParameter: null,
    operationType: 1,
    operationName: "RetrieveEnvironmentVariableValue",
    parameterTypes: {
        DefinitionSchemaName: {
        typeName: "Edm.String",
        structuralProperty: 1,
        },
    },
    };
}
}
let environmentVariableRequest = new EnvironmentVariableRequest("theia_Test");
let value = await Xrm.WebApi.online.execute(environmentVariableRequest)
    .then(function (response) {
        if (response.ok) {
            return response.json().catch(() => {
                return response;
            });
        }
    })
    .then((responseBody) => responseBody);
console.log(value);
Copy

With XrmEx:

let value2 = await XrmEx.getEnvironmentVariableValue("theia_Test");
console.log(value2);
Copy

In Conclusion: The advanced features of the XrmEx library further exemplify its power in simplifying and enhancing the Dynamics 365 development experience. By abstracting away the complexities, developers can focus on the core logic and functionality of their applications.
