In my model I have the below property
public int? Data
{
get;
set;
}
and using @Html.TextBoxFor(m => m.Data)
I am adding it in the view.
I have another property in the model
public DateTime? DateData { get; set; }
which I display using @Html.FormTextBoxFor(m => m.DateData, new { id = "DateData " })
How can I use the RequiredIf
attribute or any other method to make the DateData
required if the value of Data
is not 0. So anytime the value of Data
is not zero or null I want the DateData
to be a required property.

Add another property
public bool DataIsNotZero
{
get
{
return Data !=0 || Data !=null ;
}
}
Then using RequiredIf
[RequiredIf("DataIsNotZero", true, ErrorMessage = "Required!!!")]
public DateTime? DateData { get; set; }
Please note:
As pointed out in the comments, Required if
is not a built-in attribute. You need to download and import third party library:
