Remarks

The StartDateChanged event allows you to handle changes to the component’s start date.

<DxDateRangePicker StartDate="@modelStartDate" 
                   EndDate="@modelEndDate"
                   StartDateChanged="@((DateTime newStartDate) => OnStartDateChanged(newStartDate))"
                   EndDateChanged="@((DateTime newEndDate)=> OnEndDateChanged(newEndDate))" />
<p></p>
@Alert_StartDate
<p></p>
@Alert_EndDate

@code {
    DateTime modelStartDate=DateTime.Today;
    DateTime modelEndDate = DateTime.Today.AddDays(7);
    string Alert_StartDate { get; set; }
    string Alert_EndDate { get; set; }

    void OnStartDateChanged(DateTime newStartDate) {
        modelStartDate = newStartDate;
        Alert_StartDate = "The start date changed:" + newStartDate;
    }

    void OnEndDateChanged(DateTime newEndDate) {
        modelEndDate = newEndDate;
        Alert_EndDate = "The end date changed:" + newEndDate;
    }
}

The StartDateChanged event is handled automatically when you use two-way data binding for the StartDate property (@bind-StartDate).
