Hi all



i dont know what is wrong in this code to show/hide a certain tab on CASE form , please help me.



TypeError: Cannot read property 'setVisible' of null
at showhide (hungerstation-sandbox.crm4.dynamics.com/.../new_showhidtabsoncase)
at eval (eval at RunHandlerInternal (hungerstation-sandbox.crm4.dynamics.com/.../ClientApiWrapper.aspx), <anonymous>:1:1)

the code is :



function showhide()
{
subjecttype = Xrm.Page.getAttribute("subjectid");
if (typeof (subjecttype) != "undefined" && subjecttype.getValue() != null)
{
if(subjecttype =="Content Upload")
{

//parent.Xrm.Page.ui.tabs.get("ContentUpload").setVisible(true);
parent.Xrm.Page.ui.tabs.get("general").sections.get("ContentUpload").setVisible(true);


}
else
{
parent.Xrm.Page.ui.tabs.get("general").sections.get("ContentUpload").setVisible(false);

    thanks a lot.

    i knew the problem, i should use Xrm.Page.getAttribute('subjectid').getValue()[0].name

    instead of                                     Xrm.Page.getAttribute("fieldschemaname").getValue()

    thanks,

    Dear Ahmad,

    Please try following code to show if subject id is Content Upload and hide if any:

    function showhide()

    {

    Var subjectid = Xrm.Page.getAttribute("fieldschemaname").getValue();

    if(subjectid == "ContentUpload")

    {

    Xrm.Page.ui.tabs.get("tabname").sections.get("sectionname").setVisible(true);//to show section

    }

    else

    {

    Xrm.Page.ui.tabs.get("tabname").sections.get("sectionname").setVisible(false);//to hide section

    }

    }

    Hi Ahmed ,

    Its too many lines try to reduce  -

    I am assuming that subject id is your section name so try with this - 

            function showhide() {
            var subjectid = Xrm.Page.getAttribute("subjectid").getValue();
            // Make all teh section Hide 
            Xrm.Page.ui.tabs.get("general").sections.get("Document Review").setVisible(false);
            Xrm.Page.ui.tabs.get("general").sections.get("Content Upload").setVisible(false);
            Xrm.Page.ui.tabs.get("general").sections.get("OD Configuration").setVisible(false);
            Xrm.Page.ui.tabs.get("general").sections.get("Quality Check").setVisible(false);
            Xrm.Page.ui.tabs.get("general").sections.get("OrderStation Installation").setVisible(false);
            Xrm.Page.ui.tabs.get("general").sections.get("On-Boarding call").setVisible(false);
            // Show only selected Seciton
            Xrm.Page.ui.tabs.get("general").sections.get(subjectid).setVisible(true);
        }

    RE: error in Java script while showing/hiding a tab

    thanks, code is below, but i noticed that when placing "alert(Xrm.Page.getAttribute("subjectid").getValue());" at the begging of the code, the returned answer on the browser was [object Object] . this means the value of the subject is not returned to the procedure and that is why all conditions will be false.

           function showhide()

           {

               // content upload case

               if(Xrm.Page.getAttribute("subjectid").getValue() == "Content Upload")

               {

                   Xrm.Page.ui.tabs.get("general").sections.get("Content Upload").setVisible(true);   //  Make sure  you are providing correct sectionname , tab name

               }

               else

               {

           Xrm.Page.ui.tabs.get("general").sections.get("Document Review").setVisible(false); // Make sure  you are providing correct sectionname , tab name

                   Xrm.Page.ui.tabs.get("general").sections.get("OD Configuration").setVisible(false); // Make sure  you are providing correct sectionname , tab name

                   Xrm.Page.ui.tabs.get("general").sections.get("Quality Check").setVisible(false); // Make sure  you are providing correct sectionname , tab name

                   Xrm.Page.ui.tabs.get("general").sections.get("OrderStation Installation").setVisible(false); // Make sure  you are providing correct sectionname , tab name

                   Xrm.Page.ui.tabs.get("general").sections.get("On-Boarding call").setVisible(false); // Make sure  you are providing correct sectionname , tab name
