infopath

Im trying to fill a dropdownlist based on an other one: Departments and SubDepartments.

i followed this link: http://www.sharepoint-tips.com/2007/01/infopath-form-services-implementing.html

when i try to fill in a form it gives me an error: Request Failed (--> securityException) on this line: q.FileLocation = q.FileLocation + "&FilterField1=Department&FilterValue1=" + GetDepartmentValue(); and the second dropdownlist (subdepartments) is not filtered.

Any idea what might be the problem?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
