SharePoint Designer offers great functionality to SharePoint and customizing the list item forms. You are able to pass parameters by query string to a new, edit or display form in order to set default values or do some other stuff. So if you want to provide a link or generate it automatically the form could use the value to save it into the list. But you have to configure the list form.
1) Create a custom form for the list – in this example we create a custom new item form aspx page
Insert a name:
The result is:
2) Delete the current Dataformview Webpart.
3) Add a new custom list form
4) Add your Parameter
5) Use the Parameter
At this place you have to change the SPFormField to an aspx textbox.
After that you can set the text attribut and prefill it with the parameter from query string by just insert {$yourparameterName}
6) Open the form in Browser
That’s it.
