ASP .NET MVC Disable Client Side Validation at Per-Field Level

Question

I\'m using ASP .NET MVC 3 with Data Annotations and the jQuery validate plugin.

Is there a way to mark that a certain field (or certain data annotation) should only

Answer 1

To achieve this goal in the given scenario, we need to make two tweaks.

Client Side

To disable client side validation, we need to disable it by force.

@Html.EditorFor(model => model.Password, new { htmlAttributes = new {  @data_val = "false" , @class = "form-control"} })

Notice the @data_val= “false”. It will disable the validation on this field.

Server Side (In Action)

When the model is validated on the post action, ModelState.IsValid will always return false because password is not provided. Here we have to provide the current password to the model and Re-validate the model.

var userObj = db.Users_Info.Where(a => a.Id == users_Info.Id).FirstOrDefault();
if (String.IsNullOrEmpty(users_Info.Password))
{
  users_Info.Password = userObj.Password;
}
ModelState.Clear();
TryValidateModel(users_Info);

Let me explain, first we retrieve current information saved in the database which we are using later to assign to current model if password is not provided. The last two lines actually reset the ModelState to return updated result on ModelState.IsValid.
