Binding Links to Objects

You can bind links to labels, images, DBFields, formula fields, parameter fields, special fields, and the category (X) axis labels, legend labels, or data markers of charts. The link can either be a simple link or a conditional link. With conditional link, different targets can be loaded based on different conditions. However, conditional link is not supported on independent objects placed into a component that is not bound to a dataset, for example in a tabular cell.

To bind a simple link to an object:

1. Right-select the object and select Link on the shortcut menu to display the Insert Link dialog.
2. From the Link Type drop-down list, select the target to which the object will be linked: Report, URL, E-mail or Content.
3. Specify the options for the link target.
4. When done, select OK to create the link.

To bind a conditional link to an object:

1. Right-select the object and select Link from the shortcut menu to display the Insert Link dialog.
2. Check the Conditional Link checkbox.
3. Select the button to open the Edit Conditions dialog to define a condition using either simple expressions or complex expressions according to your requirements.

   The newly added condition will then be displayed and highlighted in the conditions box in the Insert Link dialog.

4. From the Link Type drop-down list, select the target to which the object will be linked under this condition: Report, URL, E-mail or Content, then specify the options for the link target.
5. Repeat the above steps to add more conditions and define the link target for each condition.

   To edit a condition, select the condition in the Condition box, then select . In the Edit Conditions dialog, edit the expressions as required.

   To remove a condition and the corresponding format, select the condition in the Condition box and select .

   To adjust the priority of a condition, select the condition in the Condition box and then select or .

6. When done, select OK to finish defining the conditional link.

For an illustrated example, see Example of binding a conditional link.

Once a link is added to an object, you can then open the link, further edit the link settings or remove it.

• To open the link, switch Web Report Studio to View Mode, then right-click the trigger object and select Show Linked Target from the shortcut menu. If the web report is created in Web Report Studio, you can also directly select the trigger object to open the link, while for a web report created in Logi JReport Designer, whether you can do this depends on the report's Select Priority property setting at report design time. If the priority of the go-down action is specified the highest and the trigger object is in a hierarchy, you can use a select on the object to open the link only after you have gone down to the lowest level of the hierarchy.
• To edit a link, right-click the object and select Edit Link from the shortcut menu. In the Edit Link dialog, edit the link according to your requirement.
• To remove a link from an object, right-click the object and select Remove Link on the shortcut menu. In the warning message dialog, select Yes to confirm the removal.

Linking a Report to Another Report

You can make a report linked to another report, then when you select the trigger object in the primary report, you will be able to jump to the linked report to obtain information about the trigger object.

1. In the Insert Link dialog, select Report as the link type.

   

2. Select the Browse button beside the Report text field to specify the target web report you want as the linked report.
3. Specifies the window or frame in which to load the linked report from the Target drop-down list.
4. Select the More button to display more options for setting the link.
5. In the Filter tab, select above the Components box to specify which components in the linked report will be interlinked with the primary report.
6. Specify the conditions based on which the link relationship between the primary report and the selected components in the linked report is set up.
   1. Select a component in the Components box.
   2. Select the button above the Field Conditions box and a condition line is added.
   3. Select a field from the drop-down list in the Fields(Primary) column.
   4. Choose an operator from the drop-down list in the OP column. The operator can be "=", "<>", "<", ">", "<=", ">=", or "IN".
   5. Specify the field of the linked report from the drop-down list in the Fields(LinkedReport) column. All fields in the linked report of the same value type as the selected primary report field will be available.
   6. If necessary, you can specify more conditions by selecting the button and then specifying the primary report field, the operator, and the corresponding field in the linked report. Note that the relationship between these conditions is AND, which means that Logi JReport will fetch linked report data which meets all of the conditions.
   7. Repeat the above steps to set link conditions between the primary report and other components in the linked report.
7. Specify whether to apply the on-screen filters (namely, the filters created via the Filter panel and filter controls) in the primary report to the selected components in the linked report.
   1. Select the component to which you want to apply the filters from the Components box.
   2. Check Pass on-screen filters to the linked components.
   3. If the trigger component in the primary report and the selected component in the linked report use different business views, you need to select Mapping Table to define the mapping relationship based on which the on-screen filters in the primary report are passed to the linked report in the Mapping Table dialog.

      

   4. Select above to add a mapping line.
   5. Select the field that is bound with an on-screen filter in the primary report from the drop-down list in the Fields (Primary) column.
   6. All available fields in the linked report of the same value type as the selected on-screen filter field are listed in the drop-down list in the Fields (Linked) column. Select a field whose values are the same as those of the on-screen filter field.

      A mapping relationship is now set up. Then when the link is triggered, the corresponding on-screen filter in the primary report will be applied on the selected linked report field.

   7. Add more mapping lines and define the mapping relationship between the on-screen filter fields in the primary report with appropriate fields in the linked report.
   8. Select OK to go back to the Insert Link dialog.
   9. Repeat the above steps to apply the on-screen filters in the primary report to other components in the linked report.
8. From the Default Linked Component drop-down list, select the component that is displayed by default in the linked report when the link is triggered in exported result.

   For example, a linked report contains a chart and a table and the table is specified as the default linked component. When you export the primary report to PDF with linked report and trigger the link in the PDF result file, the page that contains the table will be displayed by default. You can scroll to view the chart.

9. If the linked report uses parameters, go to the Parameters tab, the Target Report Parameters box lists the parameters of the linked report. You can assign fields of the primary report to the parameters. Then, when running the linked report from the link, the field values of the primary report will be assigned to the parameters automatically.
10. If you would like the values of the filter objects like filter controls in the primary report to be passed to filter objects in the linked report, go to the Advanced tab to set up the relationship between the filter objects as follows:
    1. Select to add a line.
    2. In the Primary Report Property/Object column, select to select a filter object in the primary report in the Select Value dialog and select OK.
    3. In the Linked Report Property/Object column, select to select a filter object in the linked report in the Select Value dialog and select OK. You need to make sure that values of the filter object in the primary report can be applied to the filter object in the linked report in the same line.
    4. Follow the above steps to set up the relationship between more filter objects.
11. Select OK to apply the settings.

You can then trigger the link to open the linked report which will be displayed according to the specified link conditions. The link is also available when the primary report is opened in HTML, PDF or Excel format with the option Run Linked Report being selected.

If the linked report is opened in the same frame as the primary report in Web Report Studio, you can select on the toolbar to go back to the primary report. Select next to and you will get a drop-down list which lists the original report and the linked targets you have just visited within the link chain. The item checked on the drop-down list is the currently opened page. Select an unchecked item and you will be directed to that target.

    Addresses to be included in the "cc" (carbon copy) section of the message.
  • BCC
    Addresses to be included in the "bcc" (blind carbon copy) section of the message.
  • subject
    Text to appear in the subject line of the message.
  • body
    Text to appear in the body of the message.

Here are some examples:

• user@example.com
• user1@example.com;user2@example.com
• ${Customer Name}@jinfonet.com, here ${Customer Name} is a field name. Note that, fields can work in the hyperlink only when they are inserted via the Add Dynamic Field option.
• salesmanager@${Country}.jinfonet.com, here ${Country} is a field name.

To make an object linked to a Blob data type field:

1. In the Insert Link dialog, select Content as the link type.

   

2. From the Query drop-down list, select the business view which contains the required Blob data type field. Only query based business views that come from the same data source connection as the business view the current report uses are available in the drop-down list.
3. From the Content Type drop-down list, specify the content type for the Blob type data. You can also select the button to bind it with a string type business view element or a record level pass one formula in the selected business view, or with a dynamic formula in the current report.
4. In the File Name text field, specify a file name for the linked Blob type data. You can also select the button to specify a string type business view element or a record level pass one formula in the selected business view to control the file name.
5. From the Content drop-down list, choose a Blob data type field in the selected business view.
6. Select the More button to display more link options.
7. In the Filter tab, specify the filter conditions between the business view used by the current report and the business view that contains the linked Blob content as follows:
   1. Select above the Field Conditions box and a condition line is added.
   2. Select the desired field of the business view used by the current report from the Fields(Primary) drop-down list.
   3. Choose an operator from the drop-down list in the OP column.
   4. Specify the field/formula of the business view that contains the linked Blob content from the drop-down list in the Fields (Linked) column. All fields that are of the same data type as the selected field in the Fields(Primary) column are available in the drop-down list.
   5. If necessary, you can specify more conditions by selecting the button and then specifying the fields and operators accordingly. Note that the relationship between these link conditions is AND, which means that Logi JReport will fetch the linked Blob type data which meets all of the conditions.
8. If the business view that contains the linked Blob content uses parameters, the Parameters tab will be enabled. In this tab, you can assign fields of the business view used by the current report to the parameters. Then, when accessing the Blob type data from the link, the field values will be assigned to the parameters automatically.
9. Select OK to apply the settings.

You can then trigger the link to download the Blob content according to the specified conditions. The link is also available when the report is opened in HTML, PDF, or Excel format.
