Get User Privilege on a field - Dynamics 365 CE

 Hi Everyone,

Today I got a requirement to check whether the user has access to read the data on the field where field level security has been enabled and do some operations.

We can achieve this using getUserPrivilege() client API.

var fieldPrivileges = formContext.getAttribute("new_fieldsecurityfield").getUserPrivilege();

Result when user doesn't have permission.

Result when user have permission.

Hope this helps.

Hide Formselector on the Form - Dynamics 365 CE/CRM

 Hi Everyone,

Today I got a requirement to hide FormSelector on the Form as Users would have access to multiple forms but we have to navigate them to right form based on a field value on the record and we shouldn't give an option to change the form to the User. 

My initial thought was it's not possible to hide formselector but one of my colleagues came up with the below piece of the code and it worked like a charm.

Logic is simple, set Visibility of the forms to False.

 var formContext = executionContext.getFormContext();
    formContext.ui.formSelector.items.get().forEach(function (item, index) {
        // hide all the form apart from Opportunity.
        if (item.getLabel() != "Opportunity") {
            item.setVisible(false);
        }
    });

Without above code, we see formselector

With code, we don't see formselector.

Hope this helps.

            if (result.entities.length > 0) {
                console.log(result.entities);
                for (count = 0; count < result.entities.length; count++) {

                    console.log("Value : " + result.entities[count].value);
                }
            }
        },
        function (error) {
            console.log(error.message);

Calculate the Age from Date of Birth in JavaScript

Hi Everyone,

Today I have got an requirement to calculate the Age based on Date of Birth.

Here is the way to get the Age using JavaScript.

function getAge(dateString) {

    // var dateString = '12/02/1988'

    var today = new Date();

    var birthDate = new Date(dateString);

    var age = today.getFullYear() - birthDate.getFullYear();

    var m = today.getMonth() - birthDate.getMonth();

    console.log(today.getMonth())

    console.log(birthDate.getMonth())

    console.log(m);

    // Logically we cannot include the current year if the birthday has not completed in the current year.

    // The below condition checks the same and removes the current year from Age.

    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {

        age--;

    }

    return age;

}

Hope this helps.

Get InitialValue of a field in JavaScript - in Dynamics 365 CE

Hi Everyone,

Today I was going through Client API from Microsoft Docs and found getInitialValue reference. I haven't used it anytime and explored little bit. 

Many times we get the requirement to compare the field values on the Save with the values that were populated on the load and to achieve this, normally we use declare a global variable in JavaScript and set the variable to the value of the field on the Load event and use it on Save for comparing. We can say good bye to these kind of logics and use getInitialValue() to get the value when the form is opened.

Here is the syntax for the same.

formContext.getAttribute(<attributename>).getInitialValue()

Note: 
1) This method works for only Boolean, OptionSet or MultiSelectOptionSet attributes. 
2) Once the record is saved, getInitialValue holds the latest value whatever that was changed by the user.

Hope this helps.

Mention height and width in Percentage instead of Pixels - Modal Popups in Dynamics 365 CE - NavigateTo

Hi Everyone,

Today a bug was created by the user saying the popup window is too small and we were using below code to show the HTML Webresource as a popup.

var pageInput = { pageType: "webresource", webresourceName: "WebResourceName" };

        var navigationOptions = {

            target: 2,

            width: 400,

            height: 300,

            position: 1

        };

        Xrm.Navigation.navigateTo(pageInput, navigationOptions).then(

            function success() {

                // Handle dialog closed

            },

            function error() {

                // Handle errors

            }

        );

When we have checked the code was working fine and able to see the window normally. After some checks with the users came to know that User has 19 inches monitor and that has opened doors to fix the issue. We all know that we have to use percentage instead of pixels for height and width and here is the way to use the same in NavigationOptions of NavigateTo function.

Here is the modified code of the same.

var pageInput = { pageType: "webresource", webresourceName: "WebResourceName" };

        var navigationOptions = {

            target: 2,

            //width: 400,

            //height: 300,

            width: { value: 90, unit: "%" },

            height: { value: 90, unit: "%" },

            position: 1

        };

        Xrm.Navigation.navigateTo(pageInput, navigationOptions).then(

            function success() {

                // Handle dialog closed

            },

            function error() {

                // Handle errors

            }

        );

Hope this helps.

function GetOptionSetText(EntityLogicalName, AttributeLogicalName) {

    SDK.Metadata.RetrieveAttribute(EntityLogicalName, AttributeLogicalName, "00000000-0000-0000-0000-000000000000", true,
       function (result) {
            for (var i = 0; i < result.OptionSet.Options.length; i++) {
                var text = result.OptionSet.Options[i].Label.LocalizedLabels[0].Label;
                var value = result.OptionSet.Options[i].Value;
            }
        },
        function (error) { }
    );
}

Hope this helps.
