How to add methods to newly added custom controls in an extended form.

(0) ShareShare
ReportReport
Posted on by Mav

I have added a new custom control namely MyContactpersonid2 in extended salescreateorder form, i want to add jumpref & lookup method from editcontactpersonname control to my newly created controls.

I have followed this community.dynamics.com/.../code-behind-extension-forms-how-to-add-state-variable-and-override-methods-without-overlayering

Code

[ExtensionOf(formStr(SalesCreateOrder))]
final class MySalesCreateOrder_Extension
{

    [FormEventHandler( formstr( Salescreateorder ) FormEventType::Initialized)]
    public void initializedFormHandler(xFormRun formRun, FormEventArgs e)
    {
        FormDataObject field1DataObject = this.SalesTable_ds.object( fieldNum(SalesTable, MyContactPersonId2), 1);

        MyContactPersonId2DataObject.registerOverrideMethod( methodStr(FormDataObject, jumpRef), formMethodStr( [ExtensionOf(formStr(SalesCreateOrder))]
       , jumpRefImplementation), this);

        FormDataObject field1DataObject = this.SalesTable_ds.object( fieldNum(SalesTable, MyContactPersonId2), 1);

        MyContactPersonId2DataObject.registerOverrideMethod( methodStr(FormDataObject, lookup), formMethodStr( [ExtensionOf(formStr(SalesCreateOrder))]
       , lookupImplementation), this);

        
    }

    public void jumpRefImplementation(FormDataObject MyContactPersonId2)
    {
        // My implementation of the override logic
    }


         public void lookupImeplementation(FormDataObject MyContactPersonId2)
         {
             //My  implementation of the override logic
         }

Error

Getting error at
    [FormEventHandler( formstr( Salescreateorder ) FormEventType::Initialized)]    // It keeps erroring  ) expected at FormEventType
    public void initializedFormHandler(xFormRun formRun, FormEventArgs e)
VSError

    Approach is fine . From you above code looks like you are missing closing bracket for class. Put that and try to build again

    ?

    That is exactly my problem all the brackets are closed yet this  ) expected error, can you let me know where do you think i should be putting extra bracket

    @Sukrut  : Any further suggestions.

    doesn't look anything wrong to me . Try to copy and paste event handler in another class and build it first just to see you get same error

    Tried in different class , :-( Same error ,   ") expected" error at FormEventType:Initiallized)]

    Can you try the code in ur system please.

  • Sukrut Parab Profile Picture

    Just notice that you are implementing event handler which is does not necessarily  be in the extension class . You can just implement in normal class Like SalesCreateOrderFormEventHandler . Here is good explanation about that

    daxmusings.codecrib.com/.../accidental-code-extensions.html\

    I tried in my environment and I did not get any error. See below definition which I copied.

    class TestEventHandler

    {

       [FormEventHandler(formStr(SalesCreateOrder), FormEventType::Initialized)]

       public static void SalesCreateOrder_OnInitialized(xFormRun sender, FormEventArgs e)

       {

       }

    }

    I think there was some issue in code, I got it fixed but now getting the following error when i click to see lookup.
    Pls suggest how to resolve this Unable to Cast Formstring control to FormDataObject.

    All I am trying to achieve is to have a similar lookup like we have for editcontactperson for my contact person

    .

    Revised code

    [ExtensionOf(formStr(SalesCreateOrder))]
final class ETSalesCreateOrder_Extension
{
    [FormEventHandler( formstr( Salescreateorder ), FormEventType::Initialized)]

    public void initializedFormHandler(xFormRun formRun, FormEventArgs e)
    {
        FormDataObject MYContactPersonIdDataObject = this.SalesTable_ds.object( fieldNum(SalesTable, MYContactPersonId), 1);

        MYContactPersonIdDataObject.registerOverrideMethod( methodStr(FormDataObject, jumpRef), formMethodStr(SalesCreateOrder,jumpRefImplementation),this);

       FormDataObject MYContactPersonId1DataObject = this.SalesTable_ds.object( fieldNum(SalesTable, MYContactPersonId), 1);

        MYContactPersonIdDataObject.registerOverrideMethod( methodStr(FormDataObject, lookup), formMethodStr(SalesCreateOrder,lookupImeplementation),this);


    }

    public void jumpRefImplementation(FormDataObject MYContactPersonId)
    {
        // My implementation of the override logic
        salesTable_ContactPersonId2.jumpRef();
    }

         public void lookupImeplementation(FormDataObject MYContactPersonId)
         {
             SalesTable lsalestable;

             //My  implementation of the override logic
            ContactPerson::lookupCustContactPerson(salesTable_contactPersonId2,lsalestable.CustAccount,editContactPersonName2,lsalestable.MYContactPersonId);

          }
		
}

    use formStringCOntrol  because  MYContactPersonId is a string control and then call register override method for that.

    FOrmStringControl MYContactPersonIdDataObject = this.SalesTable_ds.object( fieldNum(SalesTable, MYContactPersonId), 1);
