### Setting up a data container link

A data container link is used to set up a relationship between the parent and child data containers. It includes:

- A set of link conditions which are used to dynamically filter out data of the child data container.
- A set of parameter links (if the child data container has parameters) which are used to assign some fixed values to the child container parameters so that at runtime, you do not need to enter values for them.

Assume that you have created a standard banded report showing the customer information. Then, you insert a table into the detail panel of the banded object, which displays the order information. Now you want to set up some link conditions between these two containers, so that when you view the report, a table will be generated according to the ID of the customer as follows:

To achieve this, select the table and right-click it. On the shortcut menu, click Data Container Link, then specify the settings as required in the Link Data Container dialog. See the dialog.

Generally, data container link functions the same as subreport links. The only difference is that you do not need to specify a specific component that is linked with the parent data container, since you have selected the child as the target of the links. For details about how to set up data container link, refer to Creating sub links, Setting up parameter links, Returning values to the primary report.
