I have an account field, which has a dropdown box of accounts, which underlying, sends off the account number.
So when nothing is entered, the validation message says "The field AccNo must be a number." or "The AccNo field is required." The default option sometimes triggers the number type validation as it has no number assigned.
Is there any way I can change this to simply say, "Please select an Account", for cases where nothing is entered AND when it assumes a number isnt entered.
Sure, you could decorate the property you are binding your dropdownlist to with the [Required] attribute which will enforce the user to select a value:
public class AccountViewModel
{
[Required(ErrorMessage = "Please Select an Account")]
public string AccountNumber { get; set; }
public IEnumerable<SelectListItems> Accounts { get; set; }
}
and in the view:
@model AccountViewModel
...
@Html.DropDownListFor(
x => x.AccountNumber,
Model.Accounts,
"-- select an account --"
)
I'm not sure that I understand you completely, but can't you just use the annotation:
[Range(0, 99999,ErrorMessage = "Please select an Account")]
on the field in your model ?
(I used the Range validation only for the example)
