Remarks

LinkSettings allow users to configure one WebCombo to be dependent on another WebCombo without writing any line of codes. The WebCombo instances which have LinkSettings Enabled should be set in Bound mode, as its datasource will be automatically filtered based on the value entered in specified ParentWebComboID. This feature supports most scenarios from basic single dependency scenario to combined dependencies scenario. Developers can also write their custom codes in order to use their own filtering algorithm for advanced LoadOnDemand scenario

The Linked WebCombo feature supports following scenarios:

  1. Single dependency mode. This is the most common scenario in web application, where one WebCombo should depend on the value of another WebCombo. It involves only one-to-one relation between one WebCombo and another. The most common scenario is such as the relations between Division, Manager and Staff.
  2. Multiple dependency mode. This mode allows you to configure a WebCombo to be dependent to more than one WebCombo. The users are then required to fill the specified Parent WebCombo(s) first prior to be able to select a value in the linked combo. For example, Supplier list that based on ProductCategory and City. Both ProductCategory and City are independent and not linked. However, the Supplier list requires both ProductCategory and City to be filled prior to be able to select a Supplier.  
  3. Combined dependency mode. In this advanced scenarios, an array of WebCombo instances can be linked in several ways, some of them could be linked using Single dependency mode, and others can be linked using Multiple dependency. Combined scenario is the combination of single and multiple dependencies scenario in order to create an array of linked WebCombo instances, where one WebCombo is dependent to another WebCombo and another WebCombo is dependent to one or more than one other instances. One common scenario for the combined mode is similar to following, where Vehicle input requires VehicleType to be filled first, next the available dealers is dependent to VehicleType and Dealer input. These links between single and multiple dependencies creates an array of linked WebCombo named Combined Dependencies. Dealer and Models are configured in Bound mode, and others in Unbound mode to demonstrate more advanced scenario.
  4. Unbound mode. The LinkedWebCombo feature supports Unbound mode specifically. You can define LinkSettings in the similar way as in Bound mode, and have the linked WebCombo filtered in the client side automatically.
