I want to filter list items on the basis of sharepoint user group name.
only list items which having Value in Column-Vendor same as Sharepoint group should able to see that list item.
I am using following CAML query
<Membership Type="CurrentUserGroups"><FieldRef Name="Vendor"/></Membership>
but its not working, I tried following also
<Membership Type=\"CurrentUserGroups\"><FieldRef Name=\"Vendor\"/></Membership>
but still its not filtering but showing all list items for the user.
