Tree Control Data Binding dialog box

Use this dialog box to specify data binding.

Field Description
Top-Level IDO Select an IDO to populate child nodes from the root level of the tree. To test the connection to the IDO, click Top-Level IDO. A label for the top-level node can be specified in the Caption option in the Component property sheet. A root node icon can be specified in the Bitmap File Name option in the Component property sheet. The default icon represents a folder.
Custom Load Method Specify a custom load method on the node. With a custom load method, you cannot alter the list of IDO properties. The Properties field and standard IDO collection load options are disabled. You can use the TMP keyword to refer to a property value.
Method Parms Click to add, edit, or reorder parameters required by a custom load method.
Properties Click Properties to select one or more properties to include in nodes at the root level. Property values display in a node from left to right in the order in which they appear in the list and are separated by commas.
Props to Display Click Props to Display to specify which of the properties specified in the Properties field are to display in each node. This feature allows you to include hidden properties in nodes. You can use the properties in linkages to the next level of the tree, and the properties can be accessed programmatically when the user clicks a node.
Read Mode The isolation level for transactions when loading the collection for the current level. This setting overrides the default value for Collection Read Mode set in the core form Process Defaults. The override applies only to the current IDO in the tree.
Filter The parameters of the FILTER keyword, which sets query criteria.
Distinct Select the check box to apply the DISTINCT keyword to the collection of nodes. Otherwise, clear this check box.
OrderBy The parameters of the ORDERBY keyword, which controls the sorting of the collection.
GroupBy The parameters of the GROUPBY keyword, which specifies the groups into which nodes are to be placed.
Record Cap Override Specifies a record cap for the selected collection.

This setting is subject to any system-wide record cap overrides that might be in effect.

Prefix/Format The prefix displays to the left of property values in nodes. You can specify a single prefix for all property values in a node or separate prefixes for each property value. The field is optional.

To use a single prefix, type a literal value or select a string name from the list. You can click Prefix/Format to create a string. Property values are separated by commas in the displayed tree.

To use a separate prefix with each property value, use the TNP keyword.

Font Specify font settings for text displayed in nodes.
Image Specify a node image to represent this level of the tree. The graphic file should be located on the client. The default icon represents a folder.
Selected Image Specify a node image to indicate that a node is selected. If Image is specified and Selected Image is not specified, Image is used in both the selected state and the non-selected state. The graphic file should be located on the client.
All Levels Use Same IDO Select this check box for a recursive tree (one in which each level uses the same IDO). The Link By field is enabled and you can specify the recursive linkage from one level to the next on this IDO. If you clear the check box, the current level's list is enabled and you can specify each sublevel of the tree separately.
Ignore Target Level Filter Spec To ignore the target node Filter specification while looping back with the recursive option All Levels Use Same IDO selected, select this option.
Link By The linkage between levels in a recursive tree. Click Link By to set the linkages.
Method Parms Click to add, edit, or reorder parameters required by a custom load method.
Up Click to move the selected level up one level in the tree.
New Click to specify a new level in a nonrecursive tree.
Edit Click to change the specifications for the selected level in a nonrecursive tree.
Delete Click to delete the selected level.
Down Click to move the selected level down one level in the tree.
