How to implement enable rule on a ribbon button using ribbon Workbench in MS CRM

Hello Folks,
In this post we are going to learn how to implement enable rule on a system/custom button on ribbon of MS CRM form using ribbon workbench solution.

Here i have created a step by step procedure of implementing enable rule in MS CRM.
The test scenario i have created is as follwos:

1. Entity  : Task
2. Button : Convert to Case
3. Event  : On the value of option set field Priority

The test scenario is such that Covert to case button should be only visible on Task entity when Priority field is set to High otherwise Convert to Case button should be hidden.

I have included following javascript function in a library to check the value of Priority field:


///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
function enbleconverttocase()
{
var value =Xrm.Page.getAttribute("prioritycode").getValue();
if(value!=null)
{
if(value ==2) //Value 2 = Priority High
return true;
else
return false;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Step 1 :
a) Open the desired solution which contain your entity on which you want to implement enable rule and the library having javascript function similar to the one above.

Note: For fast load and upload/publish of solution, keep solution small i.e. don't add unnecessary components.

In my case solution name is test enable  rule:

b) Select the desired solution and click OK

Step 2: Right click on the desired button and click Customise command.

In my case it's "To Case".

Step 3: 

a) You'll see command as shown in image below.

b) No need to do anything here.

Step 4: Right Click on enable rule and select add new.

Step 5:

b) Right click on the new rule created and click add new.

Step 6: Select Custom javascript rule and click add.

Step 7: Now right click on the created enable rule and select Edit enable rule.

Step 8:  

a)Now edit your custom rule as shown below:

• Default                 :      True

b) Click OK

Step 9:
