Totals

Total Report Customization is the mantra of the DXPivotGrid. End-users are free to change the control's layout to generate the perfect report. From a very general overview of the data to each and every individual detail in a single report - everything can be accomplished at runtime with just a few drag and drop operations. Illustrative of the DXPivotGrid's powerhouse feature-set is its summary computation capabilities. As end-users increase the amount of detail in a report, a more general overview of the data is present - totals. So end-users won't have to change the report's structure each and every time they need more or less detail. Only a single report is required since there is no need to choose between complexity and detail or simplicity and less information - they get it all in one place. And as you will see a little later on, you also don't have to do a single thing to achieve this!

Automatic Summary Computation - Group and Grand Totals

In general, automated solutions are always more efficient than those that must be implemented manually. As such, the DXPivotGrid ships with an automatic summary computation engine - an intuitive way in which to provide instant data analysis options to your customers.

Automatic computations are enabled by default and calculate the same aggregate function's value as is calculated in data cells. When you change a field's summary kind, these totals are automatically updated to calculate the same function. Thus, you don't have to worry about any additional customizations - a more general data view is always available.

There are two kinds of automatic totals - grand totals and group totals. Grand totals may be the only thing displayed in a report. For instance, end-users may need to display the sales volume for each product without any additional details. Or they may need to see yearly sales without concerning themselves with the quantity of sales for particular products.

If values are displayed hierarchically in a report, end-users can expand parent values to see more detailed data. At the same time, an automatic group total is displayed for each expanded group. Thus, end-users still see a summary for the entire group. More and more details can be added into a report, but not a single thing is sacrificed.

Manually Specified Totals

Manually specified totals let you uncouple the data displayed within the report and group totals. The number and type of automatic totals always matches the number of data fields and their summary types. Manual totals give you more control - you can create any number of group totals for each field and specify any aggregate function types.

Common Features

Whichever approach you take for the display of totals, you can control how totals are aligned with respect to corresponding data cells. By default, totals are displayed after the data. You can change this using a single option. The following image describes a pivot grid control whose totals are displayed before the corresponding data.
