Glossary Item Box

You can create row templates, also called aggregation subtotals or multiple-line columns. You can display multiple lines within a column, such as to display address information together in one column that involves multiple fields of information.

Row Template (multiple-line columns) Example

In this figure, the ID and name information appear staggered in a single column and the street address and city information appear in the same column.

The parts of the API that are involved with this feature include:

The worksheet template contains a column header template and a row template. Layout information such as cell spans, column count, and row count is stored in the worksheet template.

This feature has the following effects on other features:

The following code example creates this image.

 

Using Code

  1. Set the LayoutMode property for the sheet.
  2. Set the template to the WorksheetTemplate property for the sheet.
  3. Set the ColumnCount property for the template.
  4. Set the row count for the column header template and the row template.
  5. Set the cell spans for the column header and row templates.
  6. Create data for the cells.
  7. Use the DataIndex property to put data in the cell.

Example

This example assigns a layout mode for the column headers.
