Load JS webresource on EnableRule of a ribbon button

(0) ShareShare
ReportReport
Posted on by Vineet Mehra 75

Problem:

In Dynamics 365 I have one custom entity say CustomEntity. In that entity's Home Grid Page (List View page, where we get Active/Inactive and so on views) and in entity's form I have added one custom ribbon button, say CustomRibbon. Now, that ribbon button should be visible to users having specific security role, say CSR Admin. How to achieve this ?

What I have tried:

Added custom js (for checking particular Role) in EnableRule for CustomRibbon button. It is working fine for form but not for Grid/List View page of the entity. Reason - js Library is not loading in Grid/List view.
I have also tried callling dummy function for the library and try to call it (so that js webreource can be loaded) on Enable rule, but still it is not working.

    RE: Load JS webresource on EnableRule of a ribbon button

    Hey Andrii,

    I was also able to solve it today.

    My code is also working, provided I am passing some parameter to the function (although I don't need it, but thats how it is working).

    Thanks for your time and solution!

    Winnie,

    Here is what how I made it work for me:

    1. Code:

    function isRoleAvailable(roles) {
    var isAvailable = false;

    var allRoles = roles.split("|");

    var req = new XMLHttpRequest();
    req.open("GET", Xrm.Page.context.getClientUrl() + '/api/data/v8.2/roles?fetchXml=<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true"><entity name="role"><attribute name="name" /><link-entity name="systemuserroles" from="roleid" to="roleid" visible="false" intersect="true"><link-entity name="systemuser" from="systemuserid" to="systemuserid" alias="ac"><filter type="and"><condition attribute="systemuserid" operator="eq-userid" /></filter></link-entity></link-entity></entity></fetch>', false);
    req.setRequestHeader("OData-MaxVersion", "4.0");
    req.setRequestHeader("OData-Version", "4.0");
    req.setRequestHeader("Accept", "application/json");
    req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");
    req.onreadystatechange = function () {
        if (this.readyState === 4) {
            req.onreadystatechange = null;
            if (this.status === 200) {
                var results = JSON.parse(this.response);

                var userRoles = results.value;

                for (var i = 0; i < userRoles.length; i++) {
                    for (var j = 0; j < allRoles.length; j++) {
                        if (userRoles[i].name.toLowerCase() === allRoles[j].toLowerCase()) {
                            isAvailable = true;
                            break;
                        }
                    }

                    if (isAvailable)
                        break;
                }

            }
        }
    };
    req.send();

    return isAvailable;
}


    2. Usage of that function in custom enable rule:

    If you have several roles that should allow user to see/use button you can pass those roles through separator - | like System Administrator|System Customizer.

    Thanks Andrii, It will be helpful if you can provide a similar query and how to execute it.

    Your problem in

    Xrm.Page.context.getUserRoles

    line. It's not available in grids. You will have to build query to get current user instead.

    RE: Load JS webresource on EnableRule of a ribbon button

    I am checking whether the user is having "Field Service - Administrator" role or not.

       fetchUserRoleId: function () {

           debugger;

           var currentUserRoles = Xrm.Page.context.getUserRoles();

           for (var i = 0; i < currentUserRoles.length; i++) {

               var userRoleId = currentUserRoles[i];

               var userRoleName = Winnie.AccountMain.getRoleName(userRoleId);

               if (userRoleName == "Field Service - Administrator") {

                   return true;

               }

           }

           return false;

       },

       getRoleName: function (userRoleId) {

           var name = null;

           var req = new XMLHttpRequest();

           req.open("GET", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/roles(" + userRoleId + ")?$select=name", false);

           req.setRequestHeader("OData-MaxVersion", "4.0");

           req.setRequestHeader("OData-Version", "4.0");

           req.setRequestHeader("Accept", "application/json");

           req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

           req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");

           req.onreadystatechange = function () {

               if (this.readyState === 4) {

                   req.onreadystatechange = null;

                   if (this.status === 200) {

                       var result = JSON.parse(this.response);

                       name = result["name"];

                   } else {

                       Xrm.Utility.alertDialog(this.statusText);

                   }

               }

           };

           req.send();

           return name;

       }

    RE: Load JS webresource on EnableRule of a ribbon button

    Andrii, the snapshot is having all the components I am using. I have added CustomRule option of EnableRule for Funds button. Right now, I am not worried about Action of that button.

    If possible for you can u please try implementing this scenario.

    It will not take much time. If u want I will share the js code also.

    Please provide a screenshot of Enable Action in which you load required library.

    Thanks Andrii, Gopalan

    I have used isNaN or dummy functions earlier also for Actions and they worked fine.

    In above snapshot, I have added 2 Funds button one on HomePageGrid and other on the form and added the same enable rule for both button commands. For simplifying it I am just calling a function of AccountMain Library which is checking the role of a user and returning true or false. I am not referencing any other library.

    For Form it is working as expected but not HomePageGrid.

    RE: Load JS webresource on EnableRule of a ribbon button

    Hi

    If you are using multiple JavaScript (library) files, along with the JS file in which you are having the function to be used.

    1. Add those library files to webresources

    2. For Actions, add the library files with the function name

    NaN

    3. For Enable rule add the library files with a function which would return true,

    for example:

    function General_IncludeInRibbon()
{
   return true;
}

    or
    isNaN
    as mentioned by Andrii
