Click at the desired location to create the control.
Go to the "Content" tab of the TreeView Table control description window. Select the population mode: "From a variable".

Defining the data sources of the TreeView Table control

To define the data source of the TreeView Table control:

Click "Add". A "<None>" data source is automatically added.
Define the characteristics of this source:
- Source: corresponds to the variable to be browsed (e.g. Google advanced variable, RSS, etc.).
- Browse: corresponds to the variable used to browse the source.
- Displayed: corresponds to the variable displayed in the first column of the TreeView Table control field..
  Note: For each level, it is possible to customize the rolled and unrolled image displayed..
If necessary, define the source of the link of the previous level. For example, if the first level iterates over the garrCustomer variable, the second one can iterate over the garrCustomer.Order variable.
Define as many sources as necessary.

The first column of the TreeView Table control displays the data from the selected sources.

Defining the bindings of the different columns in the TreeView Table control based on a variable

By default, the first column of the TreeView Table control (i.e., the column that represents the hierarchy) displays the elements specified in the data sources ("Content" tab, value to "Display" of the different sources).

The TreeView Table control can also display other data in its other columns.

To define the bindings of the different columns:

If necessary, create a new column ("New" in the description window of the TreeView Table control) or select an existing column.
Go to the "Binding" tab and define the desired data binding.
Note: The link concerns one of the source variables of the TreeView Table control.. If one of the elements displayed in the TreeView Table control is modified, these changes are automatically reflected in the bound variable.
