Hi,
I need user based field control inline edit mode (readonly or not), however until now I could not success with below two codes. If will be happy if you help me please.
ROLES

Sales Rep. : Warehouse and Delivery fields should be ReadOnly.

Sales Manager: No restriction (ReadOnly) on Warehouse and Delivery fields.
FIED NAMES

Warehouse (combo)

Delivery (textbox)
FIRST SOLUTION; (please see attached result file)

1. List View > Before Display
   
   If session("myRole") = "Sales Rep" Then
   
   pageObject.readOnlyFields("Warehouse")
   
   End If
   SECOND SOLUTION;
   
2. List View > JavaScript
   
   var ctrlWH = Runner.getControl(pageid,'Warehouse');
   
   if (myAuth=='Sales Rep')
   
   {
   
   ctrlWH.makeReadonly();
   
   }
   Snippet Area:
   
   Response.write "<script> window.myAuth = '" & Session("myRole") & "'</script>"
   Note: Session("myRole") is defined during login process.
