The following data analysis filters are available:

Top / Bottom N

Displays a specific number of topmost/bottom-most values. You can specify this number as an absolute or percentage value.

Above / Below Average

Displays values that are above/below an average value.

In Code

Use the DataControlBase.FilterString property to apply data analysis filters in code:

grid.FilterString = "[#TopItems]([Profit], 10)"; // Profit in Top 10 Items
grid.FilterString = "[#TopPercent]([Profit], 10)"; // Profit in Top 10%
grid.FilterString = "[#BottomItems]([Profit], 10)"; // Profit in Bottom 10 Items
grid.FilterString = "[#BottomPercent]([Profit], 10)"; // Profit in Bottom 10%
grid.FilterString = "[#AboveAverage]([Profit])"; // Profit Above Average
grid.FilterString = "[#BelowAverage]([Profit])"; // Profit Below Average
grid.FilterString = "[#Unique]([Profit])"; // Profit is Unique
grid.FilterString = "[#Duplicate]([Profit])"; // Profit is Duplicate

You can also use the DataControlBase.FilterCriteria property:

grid.FilterCriteria = new FunctionOperator("#TopItems", new OperandProperty("Profit"), new OperandValue(10)); // Profit in Top 10 Items
grid.FilterCriteria = new FunctionOperator("#TopPercent", new OperandProperty("Profit"), new OperandValue(10)); // Profit in Top 10%
grid.FilterCriteria = new FunctionOperator("#BottomItems", new OperandProperty("Profit"), new OperandValue(10)); // Profit in Bottom 10 Items
grid.FilterCriteria = new FunctionOperator("#BottomPercent", new OperandProperty("Profit"), new OperandValue(10)); // Profit in Bottom 10%
grid.FilterCriteria = new FunctionOperator("#AboveAverage", new OperandProperty("Profit")); // Profit Above Average
grid.FilterCriteria = new FunctionOperator("#BelowAverage", new OperandProperty("Profit")); // Profit Below Average
grid.FilterCriteria = new FunctionOperator("#Unique", new OperandProperty("Profit")); // Profit is Unique
grid.FilterCriteria = new FunctionOperator("#Duplicate", new OperandProperty("Profit")); // Profit is Duplicate
