object that encapsulates the complete handling, logic and ready-to-use dialog boxes for the reporting template creation task.

When loading a data source into the DataSourceManager, the data structure is used to fill the Insert Merge Field drop-down lists. Consider the following simple JSON data object:

Loading...

When loaded using the DataSourceManager, the drop-down list displays the data column names:

Unmasked data

Even if the data column names in this example are not really cryptic, real-world database structures and naming can be complex and confusing for end-users. This concept shows how to change the drop-down item display text for merge fields to provide end-users additional information.

The first data row of the data source is used to change the drop-down items with user-friendly strings. The following data source is used in this example:

Loading...

When changing the strings after the data has been loaded into the DataSourceManager, the drop-down items show user-friendly strings instead of the actual data column names.

Loading...

When clicking on a merge field drop-down item, a valid field is inserted with the actual name and not the masked user-friendly string.

Masked data

The following function can be called after data has been loaded into the DataSourceManager. It finds the Insert Merge Field drop-down button, gets the currently selected master table that is automatically returned by the DataSourceManager and calls the ApplyMaskedString method:

The ApplyMaskedString function loops through all merge field drop-down items in order to replace the text property with the first associated data from the first data row in the data source. In case of a child table, the ApplyMaskedString function is called recursively.
