Passing default values to data form add In

Blackbaud CRM 

In one of my project, I wanted to add a custom action “Add membership” in action group in left hand 
side, see below image

 If you see in above image, first thing to take the values from this OOB Opportunity page to my Add Membership form. First thing, I had made a expression view data form spec to get the fields from Opportunity page. The values which I needed to pass from this page to Add Membership Add In forms are mentioned below in a form of form field.

      <common:FormField FieldID="PROSPECTID" Caption="Prospect Id" Description="Constituent ID" DataType="Guid"  />
      <common:FormField FieldID="RESPONSEDATE" Caption="Response Date" DataType="Date" Description="Opportunity Response Date"  />
      <common:FormField FieldID="MEMBERSHIPPROGRAM" Caption="Membership Program"  DataType="Guid" />
      <common:FormField FieldID="OPPORTUNITYLEVEL" Caption="Opportunity Level"  DataType="Guid" />
      <common:FormField FieldID="ASKAMOUNT" Caption="Ask Amount "  DataType="Money" />
  <AlterExistingPages xmlns="bb_appfx_pagedefinition">
      <AlterPage PageID="8b97a047-e267-4e9f-822d-f74cbf1447e5">
          <PageExpressionForm DataFormInstanceID="87b33727-dcd1-4dfc-a4da-bad2440adcd3"/>
  <common:DataFormExtension DataFormInstanceID="fb0f139d-5242-4375-a579-fbb829e0515f"  RenderStyle="AfterParent" TabCaption="Parent Information" />

If we see in above lines, there are 5 fields included in the form fields which I wanted to pass into Add Membership form and after this I have added Alter existing page in which I have added this expression view data form into Opportunity page and also made this expression view data form as an extension of OOB expression view data form.

After this, next step is to pass these values in Membership Add form. So I used below mentioned code

<AlterPage PageID="8b97a047-e267-4e9f-822d-f74cbf1447e5">
          <AlterPageActionGroup PageActionGroupID="08ce3a00-5bc8-475e-bd68-5c5216993845">
                <Action ID="14430078-F027-4E5E-8943-A89B24204768" Caption="Add membership" ImageKey="RES:newitem">
                  <common:ShowAddDataForm DataFormID="2852e35e-9b16-4f98-906c-51b7740e1ab4">
                        <common:SpecificPage PageID="51dec945-6a5f-4c40-ad4a-dc3ff36cddb4" />
                      <common:DefaultValue FieldID="DATE">
                      <common:DefaultValue FieldID="BILLTOCONSTITUENTID">
                      <common:DefaultValue FieldID="MEMBERSHIPAMOUNT">
                      <common:DefaultValue FieldID="COMMENTS">

In above code, you could see that I have called showadddataform and this form is basically a Membership Add form data form instance id and using default value tags to pass the values. See yellow highlighted area above. I have used some fields from Membership add form like DATE field in Membership add form contains the RESPONSE DATE from opportunity expression view data form, also I passed PROPSECTID to membership add form into BILLTOCONSTITUENTID. I wanted to use similar field data type to pass the values.

Now its turn to discuss the Membership Add In spec, how these values receive at this level. So I made a Membership Add In spec.

       Name="Membership AddIn Custom"
       Description="An addin for the Membership Dues Add Data Form data form"
       Author="Blackbaud Professional Services"

       <DataFormAddIn AssemblyName="Blackbaud.CustomFx.EventCustomization.Catalog" ClassName="Blackbaud.CustomFx.EventCustomization.Catalog.MembershipAddIn" />


In Add IN class, see the below code how I got these values.

'Add Membership form default values'
    'Mapping of DATE (Add Membership form) ---> RESPONSEDATEOpportunity page)
    'Mapping of BILLTOCONSTITUENTID(Add Membership form) ---> PROSPECTID(Opportunity page)
    'Mapping of MEMBERSHIPAMOUNT(Add Membership form) ---> ASKAMOUNT(Opportunity page)
    'Mapping of COMMENTS(Add Membership form) ---> ContextId (Opportunity page)
    Private Sub OnInit()
        ' Get Oppertunity Id from Comments field and set it on local variable opportunityId
        ' COMMENT field value set from default value tag and PageContextID set in COMMENT Field
        'which is on Opportunity page

        If Me.COMMENTS.Value <> String.Empty Then
            opportunityId = Guid.Parse(Me.COMMENTS.Value)
            Me.COMMENTS.Value = String.Empty
        End If
        If (Me.BILLTOCONSTITUENTID.Value <> Guid.Empty) Then
        End If

        'This method is called when the UI model is created to allow any initialization to be performed.
    End Sub

If we see above code, we found that based on Membership Add form fields, some business logic implemented. Please see the comments also in green above code snippet. So everything has been done on OnInit event.

For saving the data from Add In , I used below mentioned code

Private Sub MODEL_Saved(sender As Object, e As AppFx.UIModeling.Core.SavedEventArgs) Handles MODEL.Saved
        ' now we should save our custom field value to the database
        ' use Me.MODEL.GetRequestContext to send a request via theappfx
        ' web service to save our dataform extension
        If Me.TRACKTYPECODEID.Visible = True Then
            Dim connection = Me.MODEL.GetRequestContext().OpenAppDBConnection
            'Insert Comp Track Type code under Opportunity Id'
            USR_USP_INSERTMEMBERSHIPTRACKCODE.ExecuteNonQuery(connection, opportunityId, New Guid(Me.MODEL.RecordId), Me.TRACKTYPECODEID.Value, Me.TRACKCOMMENTS.Value)
        End If

    End Sub

    Private Sub MODEL_Saving(sender As Object, e As AppFx.UIModeling.Core.SavingEventArgs) Handles MODEL.Saving
        ' when the form is saving the field we added to the
        ' fields collection will raise an error as it does
        ' not exist in the form definition
        ' let's move the field value to a variable
            Me._tracktypecodeid.Value = Me.MODEL.Fields("TRACKTYPECODEID").ValueObject
            Me._trackcomments.Value = Me.MODEL.Fields("TRACKCOMMENTS").ValueObject
            ' now remove the field from the fields collection to
            ' prevent field not in form definition error message
            If (Not e.Cancel) Then
            End If
        Catch ex As Exception

        End Try

    End Sub

We would use “Model_Saved” event to save the data into the database, means after normal execution of Membership add form then it will enter into Saved event and we can manage our save criteria.
