throw an exception for relatedlist del action

Hi Friends,

 

I have a small requirement , please let me know whether it is a valid one or not.

 

I am displaying  Account Contacts using a relatedlist in a Visual force page(Standard Controller to Account object Extensions a class) , in which for a certain role like CEO i should not allow the contact to be get deleted . I have to do this using related list(not by other means such as a table datalist) , so i have overriden the del action of Contact object with a visual force page and i am calling a action method on it page load.

 

I am able to check the CEO record and stop the record from getting delete, but my requirement is to display a message  to the user that the record cannot be deleted. 

 

I am ok with custom confirm message (Are you sure?), just need to throw an exception in the visual force from which the del action commensed.

 

I have tried using trigger on before delete for Contact object, but the error message should be displayed on the VFP.

 

Please let me know how this can be done,or i am thinking in a wrong direction

 

Regards,

Hi,

To redirect to page 2 , you can use :

 

    public PageReference redirectFuntion()
    {
        PageReference pageRef= new PageReference('/APEX/Page2');
        pageRef.setredirect(true);
        pageRef.getParameters().put('idRedirect','Hello');                       
        return pageRef;
    }

 it will pass the Hello label to 2nd page using through parameter 'idRedirect'

 

to retrieve it in 2nd page just use : this.Label=Apexpages.currentPage().getParameters().get('idRedirect');

 

as far as I know , apex class didnt support alert function. You may use javascript instead.

Hi ,

 

create new function for delete.

 

add the apex:message in the visualforce and define it in the apex class using :

 

        ApexPages.Message myMsg2 = new ApexPages.Message(ApexPages.Severity.Error,'You cannot delete this contact');
        ApexPages.addMessage(myMsg2);

 

is it what r you looking for ?

Hi S_Lie,

 

Thanks for the reply , actually the page 2(iam overriding the delete action of contacts with the VFP) in which the Delete action handled was different from the page 1 in which the message have to be shown.

 

Right now iam planning to show a label in the Page 2 and provide a back button

 or 

show a alert message from apex class (if possible).

 

Please let me know if it can be done in a better way.

Thanks for the reply again,

 

I have used a trigger for the event before delete on contact object to restrict the del action.

It worked out well, redirecting the control to a page with the errror Message.
