In my view I have a enumdropdownlist (a new feature in Asp.Net MVC 5.1).
@Html.EnumDropDownListFor(m => m.SelectedLicense,new { @class="form-control"})
If I execute the above code I get dropdownlist for my following enum.
public enum LicenseTypes
{
Trial = 0,
Paid = 1
}
but by default I want my dropdownlist to have a value(custom text) and this is what I tried
@Html.EnumDropDownListFor(m => m.SelectedLicense,"Select a license" ,new { @class="form-control"})
but now the problem is when i run it, my dropdownlist looks like this So, the default text I want to show doesn't appear by default. If a user selects "select a license" and tries to submit the form, it does show an error saying "select a license" but it doesn't show as default text. Something i need to change?
Ps: The image is the screenshot of the page when it loads. By default it'll show Trial as selected option.
Try to change the Index
of LicenseTypes
start from 1
not 0
like below:
public enum LicenseTypes
{
Trial = 1,
Paid = 2
}
Then you can use Range attribute
to validate the selected license type like below:
public class YourViewModel
{
//Other properties
[Range(1,int.MaxValue,ErrorMessage = "Select a correct license")]
public LicenseTypes LicenseTypes { get; set; }
}
Finally, in your view:
@Html.EnumDropDownListFor(m => m.LicenseTypes,"Select a license",new { @class = "form-control"})
@Html.ValidationMessageFor(m => m.LicenseTypes)
