The C1DateRangeEdit class provides properties and events to configure date range selection behavior, predefined ranges, and selection constraints.

Select a Date Range

The control allows selection of a start date and an end date from the drop-down calendar. The selected range is displayed in the editor and highlighted in the calendar.

// Get selected date range var range = dateRangeEdit.GetSelectedDateRange();

Use Predefined Ranges

Use predefined ranges to provide quick access to commonly used date intervals.

C#	コードのコピー
// Enable predefined ranges dateRangeEdit.Calendar.ShowPredefinedRanges = true;

Set Date Range Constraints

Use the MinValue and MaxValue properties to restrict selectable dates. Dates earlier than MinValue or later than MaxValue cannot be selected.

C#	コードのコピー
// Set minimum date dateRangeEdit.MinValue = new DateTime(2026, 04, 10); // Set maximum date dateRangeEdit.MaxValue = new DateTime(2026, 04, 23);

// Set minimum date
dateRangeEdit.MinValue = new DateTime(2026, 04, 10);

// Set maximum date
dateRangeEdit.MaxValue = new DateTime(2026, 04, 23);

Limit the Selection Range

Use the MaxSelectionCount property to restrict the number of selectable days.

C#	コードのコピー
// Limit number of selectable days dateRangeEdit.Calendar.MaxSelectionCount = 3;

Configure Calendar Dimensions

Use the CalendarDimensions property to display multiple months simultaneously.

C#	コードのコピー
// Show multiple months dateRangeEdit.Calendar.CalendarDimensions = 3;

Handle Events

The control provides events for handling date range interaction.

DateRangeSelected occurs when a date range is selected.
DateRangeChanged occurs when the selected range changes.

C#	コードのコピー
dateRangeEdit.DateRangeSelected += (s, e) => { // Handle range selected }; dateRangeEdit.DateRangeChanged += (s, e) => { // Handle range changed };

コードのコピー

dateRangeEdit.DateRangeSelected += (s, e) =>
{
// Handle range selected
};

dateRangeEdit.DateRangeChanged += (s, e) =>
{
// Handle range changed
};

Culture-Specific Behavior

DateRangeEdit reflects culture-specific formatting and calendar behavior based on the current application culture.
