Linking Combo Box and List Box objects to query driven objects

Use the Connectivity tool to link your Combo Box or List Box object to query driven layout objects, such as Grid or BarChart.

Before you begin

Before you can link objects, you must populate the OptionList and the ItemDataList of your Combo Box or List Box object with data.

About this task

To link your Combo Box or List Box object to a query driven layout object, perform the following steps:

Procedure

  1. In the Palette view, click the Connectivity tool.
  2. On the visual dashboard, click your Combo Box or List Box object.
  3. Click your layout object. The Connection Options wizard opens.
  4. In the wizard, specify the source query column that you want to use to drive your destination object.

    To link the objects, you can use the column from the OptionList property, the column from the ItemDataList property, or any other column from the result set of the query, that your Combo Box or List Box object is based on. If you use the column from the OptionList property, you link the objects by values that are displayed in your Combo Box or List Box object. If you use the column from the ItemDataList property, you link the objects by hidden values which are different from the ones that are displayed in your Combo Box or List Box object. If you use the column from the result set of the query, that your Combo Box or List Box object is based on, you link the objects by the values that are stored in that column.

    If you want to link your objects by values from the OptionList property or the ItemDataList property, make sure that you specify one and the same column name in the Connection Options wizard and in the OptionList or the ItemDataList property of your control object.

    Click Next.

  5. Select the target query column that you want to connect to your Combo Box or List Box object. Click Finish.
  6. In the notification window, click OK.

Results

You linked the objects. The information displayed in your target layout object now depends on the item selected in your Combo Box or List Box object.
