Edit a dynamic link

Edit a dynamic link to change the source variable or resolve a broken or unresolved link. Insert a placeholder such as {0} to make the link dynamic. Broken links display in the property while unresolved links display . Unresolved dynamic links cannot be resolved at design time, but they can be valid at runtime, for example, when setting a dynamic link that passes through a panel loader.
