Type (objectType)
The Type property specifies the type of the report element.
This property is automatically set when you drop a specific element on the page. You cannot edit this property directly from the Properties view.
To change a report element from one type to another, right-click and select Convert to. For further details, see Change the type of a report element.
Note: If the Type property takes the form Field
                    (report-element-type), the report element is a
                Field. The
                Type property may change if you edit the Field
                    Name property; for example, if the data type changes from a
            string to a decimal, the Type property changes from
                Field (WordBox) to Field
                (DecimalFormatBox). 
        You can find the Type property in the Object category of the Properties view.
