Strict Mode in Blazor Datetime Picker component

The StrictMode is an act, that allows the users to enter only the valid date and time within the specified Min/Max range in text box. If the input entered is invalid, then the component will stay with the previous value. Else, if the datetime is out of range, then the component will set the datetime to the Min/Max value.

The following example demonstrates the DateTimePicker in StrictMode with Min/Max range of 5/5/2019 2:00 AM to 5/25/2019 2:00 AM. Here, it allows to enter only the valid date and time within the specified range.

If you are trying to enter the out-of-range value like 5/28/2019, then the value will set to the Max value as 5/25/2019 2:00 AM since the value 28 is greater than the Max value of 25.

If you are trying to enter the invalid date, then the Value will stay with the previous value.

The following code demonstrates the DateTimePicker with StrictMode true.

@using Syncfusion.Blazor.Calendars

<SfDateTimePicker TValue="DateTime?" Min='@MinDate' Max='@MaxDate' StrictMode=true Value='@DateValue'></SfDateTimePicker>

@code {
    public DateTime MinDate {get;set;} = new DateTime(DateTime.Now.Year,DateTime.Now.Month, 05, 02, 00, 00);
    public DateTime MaxDate {get;set;} = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 25, 02, 00, 00);
    public DateTime? DateValue {get;set;} = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 28, 02, 00, 00);
}

The output will be as follows.

DateTimePicker

By default, the DateTimePicker act in StrictMode as false state, that allows you to enter the invalid or out-of-range datetime in text box.

If the datetime is out-of-range or invalid, then the model value will be set to out of range datetime value or null respectively with highlighted error class to indicates the datetime is out of range or invalid.

The following code demonstrates the StrictMode as false. Here, it allows to enter the valid or invalid value in textbox.

If you are entering the out-of-range or invalid datetime value, then the model value will be set to out of range datetime value or null respectively with highlighted error class to indicates the datetime is out of range or invalid.

@using Syncfusion.Blazor.Calendars

<SfDateTimePicker TValue="DateTime?" Min='@MinDate' Max='@MaxDate' StrictMode=false Value='@DateValue'></SfDateTimePicker>

@code {
    public DateTime MinDate {get;set;} = new DateTime(DateTime.Now.Year,DateTime.Now.Month, 05, 02, 00, 00);
    public DateTime MaxDate {get;set;} = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 25, 02, 00, 00);
    public DateTime? DateValue {get;set;} = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 28, 02, 00, 00);
}

The output will be as follows.
