Question

I used cascading lookup field custom control from

http://jaypoint.com/sharepoint-cascading-lookup-field-jquery/

when I create a field from this custom type its type becomes cascading lookup

I want to set it to be multiple lookup column

I changed the parenttype of the field to be LookupMulti

and in code when I allow multiple values I found that the type of the field changed from cascading lookup to standard lookup field which leads to loss of functionality.

is there any way to do this without changing the type of the fieled

Answer 1

Ok

I got it. the solution is to modify the schema.xml of the file to force it keep the type of the custom field.

i got it from here http://chrisforbesblogs.net/tag/lookupmulti/
