How to Add Data Field to Existing Custom List Form?

Question

Say I have created a really simple custom list via Sharepoint Designer, and then created a custom NewForm.aspx called NewFormTest.aspx to go with it. Now I have to add a field to the custom list. I understand that a custom list does not get updated automatically when a new field is created in the underlying list.

So,how in the world do I get that new field to show up in my custom list?

I know if I update the custom list and create a new NewFormTest form, that it would populate, but then I would have to go and reformat my whole list!

I can't see any way to just drag the field from "Current Data Source" in the "Data Source Details" panel. What good is that panel? I'm sure I am missing something.

I've read this thread, but didn't see what I was looking for.

Please follow the steps given below

• Open the form you need to edit in SharePoint Designer ”split view”.
• Place your cursor on and highlight the row of data below (or above) where you want to add the new field.
• Right click on the highlighted row and select Insert – Row Above (or Row Below depending on your situation). A new empty row will be added to the form.

• Highlight one of the existing field titles on your form and copy it into the first column in the new row you just created. Change the title to the title you would like to use for your new field.
• Highlight your new field title and look in the code view and verify that all of the formatting tags were also copied. Often, you will need to copy the actual code for the title from the existing to the new title to ensure the look and feel stays the same.
• Click in the second column of the new row.
• Open the Data Source Library and open the List or Library that corresponds with the form you are modifying. Click the list or Library and select Show Data. The Data Source Details window will open and scroll to the field you would like to insert.
• Select the field you want to insert right-click and select Insert as List Form Field.

• Insert a Field into a SharePoint Designer List Form Field
• The field will be added. Save your form and test in the browser.
