Tree Grid layout

A Tree Grid layout enables users to view (and possibly edit) values of a Page List or Report Definition in a display that combines the navigation benefits of a tree with a spreadsheet's access to data. Tree grids are useful when large amounts of data need to be displayed.

Specify which page property to display in each column, and each row corresponds to a single embedded page.

The tree grid is created dynamically, and will have as many rows as needed to display the requested data.

The tree grid may be read-only, simply displaying property values. You can specify that the data can be edited in a number of ways:

• all the editable fields may be displayed as editable, as in a spreadsheet
• editable fields in a row become editable when a user clicks on that row
• a modal dialog appears with the editable fields for a row when the user clicks on that row

Depending on parameters, users may be able to add or delete rows, to reorder rows, and to apply actions to rows by clicking action buttons. The action buttons may appear in areas above or below the data. Express action buttons can appear in each row, or only in the row that the user has clicked.

Use either of two ways to add a Tree Grid layout to a section:

1. From the Application Explorer, select the Page List property or Report Definition you want to use as the data source in your layout, and drag it to the section. When you release the mouse button, a screen appears asking you to specify which repeating layout to use. Select Tree Grid.
2. Select the Layout control from the Layout tab and drag it onto the section. In the screen that appears, select the Repeating radio button and Tree Grid for the type of repeating layout.
