Hide AllThe Matrix data region contains columns and rows in which the data is inserted and arranged. Columns and rows in a matrix can be dynamic or static. Each cell in a matrix contains a textbox by default, but as with the other data regions, the textbox can be replaced with any other report control. Also like other data regions, the matrix also repeats each report control it contains for each row in the dataset, but unlike the others, it also repeats horizontally for dynamic columns.
Cells
When you drop a matrix data region onto your report, it is initially composed of four cells.
The top left cell is the corner or label cell. You can leave this cell blank or use it to display a label for the matrix.
The top right cell is a column header and the bottom left cell is a row header. You can drag fields into these cells or use expressions to group the data.
The bottom right cell is used to aggregate the detail data. At run time, detail cells display aggregates of the intersections of columns and rows.
Data
The matrix data region is associated with a dataset. You can make this association in the DataSetName property in the Properties grid.
Groups
You can group the columns and rows in the matrix by opening the Property dialog, and on the Row Groups or Column Groups page, editing the Group on expression, or by dragging a field into the header cell.
You can nest column and row groups by right-clicking the UI above a column or to the left of row and choosing Add Column Group or Add Row Group, or simply by dragging another field onto the column or row into which you want to insert it.
To determine where new groups are displayed, when you drag a field into an existing group you can move the mouse up or down (for columns) or left or right (for rows) to nest the new group within the existing group, or to nest the existing group within the new group.
At run time, the nested group repeats within the original group. For instance, when you drag the City field from your dataset onto a header already grouped by Country, the report displays the first country with all of its cities, then the next country with all of its cities, and so on until all of the countries in the dataset are displayed with all of their cities.
Static Rows and Columns
To insert a static row or column, right-click the detail cell and choose Add Column or Add Row. This displays a column next to or a row above or below the existing one and adds another detail cell.
Aggregates
Groups in a matrix do not subtotal data by default. To add this functionality, right-click the group header and choose Subtotal. This adds a cell to the right of the column, or below the row. Subtotal cells have a green triangle in the upper right corner which allows you to select the subtotal and set its properties in the property grid. .
Placement of Data
You can control where data is placed in several ways. You can change the Direction property of the matrix to RTL to cause dynamic column headers to expand left instead of right.
You can also move row headers to the right of the detail cells by changing the GroupsBeforeRowHeaders property of the matrix. The integer value you supply for this property equals the number of instances of the outermost column group that displays to the left of the row headers (or to the left if the Direction property is set to RTL).
Matrix Dialog
Properties for the Matrix are available in the Matrix dialog. To open it, with the Matrix control selected on the report, under the Properties Window, click the Property dialog link.
The Matrix dialog lets you set properties on the report control with the following pages.
