Example
The code sample below uses a RangeParametersSettings class instance to create a date range parameter, set the range value to the last 7 days, and filter report data by this range.
using DevExpress.XtraReports.Parameters;
using DevExpress.XtraReports.Expressions;
// ...
XtraReport1 report = new XtraReport1();
// Create a date range parameter.
Parameter myDateRange = new Parameter();
myDateRange.Name = "myDateRange";
myDateRange.Description = "Date Range:";
// Set the Visible property to true to request the parameter value from users.
// Set this property to false to apply the parameter's value that is specified in code.
myDateRange.Visible = false;
myDateRange.Type = typeof(System.DateTime);
RangeParametersSettings myDateRangeSettings = new RangeParametersSettings();
myDateRangeSettings.StartParameter.Name = "MyDateRangeStart";
// Set the range parameter's start date to 7 days ago.
myDateRangeSettings.StartParameter.ExpressionBindings.Add(new BasicExpressionBinding("Value", "AddDays(Today(), -7)"));
myDateRangeSettings.EndParameter.Name = "MyDateRangeEnd";
// Set the range parameter's end date to today.
myDateRangeSettings.EndParameter.ExpressionBindings.Add(new BasicExpressionBinding("Value", "Today()"));
myDateRange.ValueSourceSettings = myDateRangeSettings;
report.Parameters.Add(myDateRange);
// Filter report data by the specified start and end dates.
report.FilterString = "GetDate([OrderDate]) Between(?MyDateRangeStart,?MyDateRangeEnd)";
