Bound values of controls to attributes
Only the values of controls which are bound to some attribute will be saved, meaning they have “AttributeName” and “AttributeTypeName”.
On your form, right-click on a textbox and select Properties.
Under Tekla Structures, find AttributeName and AttributeTypeName.
Type the name and the type of your attributes to the correct boxes.
Repeat steps 2-4 for every other textbox on your form.
AttributeName is the name by which you identify the control.
AttributeTypeName is the name of Tekla.Structures.Datatype for the control's contents. Possible AttributeTypeNames are Boolean, Distance, DistanceList, String, Integer, and Double.
