- put a new Matrix object to the page;
- switch to the "Data Dictionary" window, select the data column and drag it to the Matrix object;
- you can reorder matrix items with mouse (click the cell and move it to the new position);
- use cell and matrix context menu to edit items.
A matrix object must have at least one column or row and one cell. It must be connected to a datasource through the DataSource property (it will be done automatically when you drag and drop data onto it from the Data Dictionary).
