i have a property in my EmployeeViewModel.cs as below
[Required]
[RegularExpeession]
public string EmpName {get;set;}
i am maintaining regex for not to allow special characters in my empName
when i give whitespace(press space button 2 times) in my text box the RequiredField validation is not firing because it is considering whitespace as a value
how to check this whitespace issue using required attribue.
could some one help me
You can add another validation to your model called AllowEmptyStrings
[Required(AllowEmptyStrings = false, ErrorMessage = "Please Provide Emp Name")]
[RegularExpeession]
public string EmpName {get;set;}
This operation cannot be performed using: Required. I think you should use Regular Expression:
\S
which equals do a search for non-whitespace characters in a string.
