How to create readonly columns in MOSS 2007 custom list, there some methods:
1) Create a custom list definition where you can modify the schema.xml. You will have to find the field that you want not to show in the edit form and set the ShowInEditForm="FALSE" for field and the field ref. Below is a simple sample:
<Field
...
ShowInDisplayForm = "TRUE" | "FALSE"
ShowInEditForm = "TRUE" | "FALSE"
ShowInNewForm = "TRUE" | "FALSE"
.../>
<FieldRef
...
ShowInDisplayForm="TRUE" | "FALSE"
ShowInEditForm="TRUE" | "FALSE"
ShowInNewForm="TRUE" | "FALSE"></FieldRef>
2) Use the object Model. Through code you can access the specific SPfield object and set the ShowInEditForm property to False;
3) Modify the EditForm through SharePoint Designer and use javascript to find the element and hide the control.
4) Build your own Custom Rendering Template
Here I give the second approach demo.
