There are two methods of populating trees:
Data Bound - see Data Bound Items in Trees for more information.
Manual Entry - see Manually Entered Items in Trees for more information.
The Data Bound option allows you to enter one or more data sources into a tree with the Data Source Browser. Use the Data Bound option for the following:
Data display - the user will be able to navigate through the data sources in the tree to find certain items and values.
Trending - the user will be able to select an Historical data tag in the tree and drag and drop the tag onto a grid or chart for the purpose of trending.
Tree grid - the user will be able to see the data in tabular format within the tree.
Linking values to parameters - the user will be able to select a value in the tree and the value will be passed to a parameter in another object. See Linking Tree Values to Object Parameters.
The Manual Entry option allows you to enter one or more manually created data sources into a tree with the Data Source Browser or you can use the Manual Entry option to enter strings.
Manually entered strings are typically used to customize a list of values that the user will select from when the tree is linked to an object's parameter. For more information, see Parameter Connections.
Use the Manual Entry option (Data Source Browser) for the following:
Drag-and-drop of data sources - the user can select the source data from the tree (which can be any type of source including SQL SELECT statements) and drag and drop the data source on an object such as a grid or chart. The source will be added to the object. This behavior is similar to Natural Presentation (selecting a data source from the system tree). See Dragging and dropping objects onto a display.
Linking values to parameters - the user can select a value in the tree and the value will be passed to a parameter in another object. See Linking Tree Values to Object Parameters.
