Creating related items on a new item form via a non-grid related items control

In November we released a feature that allows you to create new items and link them to the current item on a new item form. Up until now, however, you could only do that with the related items control in grid mode. Starting from Forms Designer 3.0.8 you are able to do it with a non-grid mode related items control as well.

Let’s illustrate what we’re talking about. Here’s a form:

New SharePoint form with related items

Let’s add a new related contact:

Adding a related item from a new SharePoint form

It appears in the related items control:

New SharePoint form with an attached item

Then we can save the parent item, when we do so a link is created:

Linking related items to a SharePoint item after saving


Open the parent New form in Forms Designer.

Set the related items control to 'Show new items only':

Show new related items only

Add the following line of code to the JS-editor:

fd.populateFieldsInGrid($('.related-items'), {
 RelatedIssue: '{CurrentItem}'

Where RelatedIssue is the internal name of a lookup field on the child list to the parent list and related-items is a CSS class name that you need to assign to the related items control in Forms Designer.


Open child New form in Forms Designer.

Add an HTML control to the form, set CDATA to false, insert the following code to it:

<div id="_fd_parent_temp">
<asp:HiddenField runat="server" ID="_fd_parent_tempField"
__designer:bind="{ddwrt:DataBind('i','_fd_parent_tempField','Value','Load','ID',ddwrt:EscapeDelims(string(@ID)),'@_fd_parent_temp')}" />
Setting temporary parent ID in a child new form

Add the following code to the JS editor:

$('#_fd_parent_temp > input').val(;

Save the child form.


When we added a related items control and saved the form, Forms Designer added a hidden field called '_fd_parent_temp' to the target list. We then added a hidden '_fd_parent_tempField' control to the child form and bound it to the hidden field. When the child form loads, the JavaScript sets a temporary id of the parent item into _fd_parent_tempField. Finally, when the parent item is saved, Forms Designer checks '_fd_parent_temp' for the parent items’ id and sets the 'RelatedIssue' field to the parent item.

Feel free to ask your questions


  1. This feature works well only on "New" parent item`s form. But for "Edit" form of parent item - does not (after adding new child item it appears in list, but "foreign key" field is empty), so I have to use JSGrid on edit form, that works.

    1. I implemented the method described in article you provide, and everything works for edit item. But when I've created new child item from parent's edit new form and saved it, I try to create NEW parent item. And I see previously created child (related to other parent) on the "New" form. Suppose, it is somehow linked to Cookie(_fd_parent_temp).

    2. I have the same issue with Edit form. Can you share with me your JSGrid code?

  2. I have issues

    When I change HTML control CDATA to false.

    1. Most likely, you have a syntax error in your code. Ensure that your code is exactly the same as in the post.

    2. Thanks for your support, issues on Sharepoint 2010.

  3. This feature not support Sharepoint Online?. I don't find Show new items only in Sharepoint Online?

    1. Most likely you just need to upgrade the solution. Remove the app and install it again. Also, some options are not available in the Silverlight plug-in, so please, use windows application for designing forms. Find more info:
