The parameters that are sent to the webservice are defined as inner content properties with the use of the ServiceParameter control.

The ServiceParameter control should be defined with the use of the following properties:

• Name - the name of the variable, used in the webmethod
• Path - the xpath-like path to the MForm item, whose value will be sent

The server-side webmethod must contain the [ScriptMethod] attribute, and the class that this webmethod is within must contain the [ScriptService] attribute.

The definition of this method must match the definition of the ServiceConstraint control:

• The name of the method must match the value of the ServiceMethod property
• The order of the ServiceParameter properties must match the order of method variables
• The name of the ServiceParameter property must match the name of the corresponding method variable
• The ServiceParameter value must be serializable with the use of its corresponding method's type

Example:

If the definition of the ServiceConstraint looks like this:

<mfadd:ServiceConstraint runat="server" ServicePath="some/service/path" ServiceMethod="MethodName" >
            <mfadd:ServiceParameter runat="server" Name="someParameter" Path="some/parameter/path" />
            <mfadd:ServiceParameter runat="server" Name="otherParameter" Path="other/parameter/path" />
</mfadd:ServiceConstraint>
                

then the method's definition should look like this:

        [ScriptMethod]
        public bool MethodName(someType someParameter, otherType otherParameter) {
            ...
        }
