MS Dynamics CRM :Wanna customize OOB sub grid's button(s) of same entity?? Check this out !!!

It's really very hard to find a form with no sub grids . Grids in CRM could be customized in many ways by selecting different OOB grid controls .But when it comes to customizing a particular button which gets shipped soon after selecting the sub grid is something which needs to be approached with some sensitive touch .

There will be a situation where in we would need to have two or more sub grids with a small twist to the turn like only one amongst must be have a specific button(s) but not for the rest (just customize the grids but showing / hiding a button based on business), say we may need "+ New Deal Participant" for one grid but not for another just like below.

How could this be achieved ?

This could be achieved with some simple JS script for implementing the business logic to hide / show the button and XRM Tool Box's Ribbon Workbench to configure the button .

Let me try to walk through the process by steps .

Firstly include the sub grids in the target form . In my case it's Deal participant sub grids in Deal form .

Above image depicts the sub grids under a tab in Deal form . And their corresponding properties are as below .

So next would be creating a solution with the target entity which the sub grid points to Deal Participants entity in this case .

Make sure that the solution doesn't contains any dependencies , meta data info or any such components so that the solution could be easily imported into the Ribbon Workbench .

The solution should be something like below .

Now we are good to import the solution in the Ribbon Workbench and play with our customization .

Here the "Mscrm.SubGrid.dealparticipant.MainTab" is what we are in need for now.

Select the button which need to be customized and select "Customise Button" on right clicking on it . As soon as it's done , we can see something like the below Mscrm.SubGrid.dealparticipant.AddNewStandard and there would be some default "Display Rules " and "Enable Rules" . We can create one as per our requirement . In our case we need to disable the Add new button based on rule .And the JS would be like

DealParticipantRibbon = (function () {


? ? function showHideAddButton(selectedControl) {


? ? ? ? var isVisible = true;
? ? ? ? var viewId = selectedControl._controlDescriptor.Parameters["ViewId"];
? ? ? ? if (viewId == "{6946A788-B9EF-EB11-94EF-000D3A09E388}") {
? ? ? ? ? ? isVisible = false;
? ? ? ? }
? ? ? ? return isVisible;
? ? }


? ? return {
? ? ? ? showHideAddButton: showHideAddButton
? ? };        

})();        

Here it's important that the crmparameter selected is selectedControl as below and publish the solution

once published , we can get the expected outcome as below
