How to check that DatePicker is not empty?

[elshorbagy]

Hi,

I have a DatePicker component and I want to check if it has a value. I tried to use <Validation Validator="ValidationRule.IsNotEmpty"> but it kept saying that the DatePicker was empty even if there was a date value.

Thank you

You should check the binded value, not the field or method of the DatePicker

Example

<DatePicker @bind-Date="@selectedValue" />
@code{
  DateTime? selectedValue;

  void SomeMethod()
  {
    if(selectedValue == null)
      // do something
  }

@stsrki I want to use <Validation Validator="ValidationRule.IsNotEmpty">, is that possible?

The ValidationRule.IsNotEmpty is used mostly for string types. If you want to check for date value types then you can create your own validation handler and use it.

void IsNotEmpty( ValidatorEventArgs e ) => e.Status = e.Value is not DateTime ? ValidationStatus.Error : ValidationStatus.Success;
