Mvc 4 validation summary errors not displaying

Question

I am having trouble displaying validation summary, I only want to display errors in validation summary, not beside the field. In my view i have,

    @Html.ValidationSummary()
    @Html.ValidationMessageFor(m =>m.Name)

in my controller i have

ModelState.AddModelError("Name",
                                "name is required");

Am i not supposed to get a validation error message? at the top? I don't get what i am missing...

I am also including these script files.. jquery.validate.min.js jquery.validate.unobtrusive.min.js

Answer 1

Try

@Html.ValidationSummary(false)

so that it will not exclude property errors.

OR

Try the method @xurca linked which is to add the model error with an empty key so it is not tied to a specific property.

ModelState.AddModelError(String.Empty, "name is required");

If you custom named your field like

 @Html.TextBoxFor(model => model.Name, new {  id = "staffSearchFilterName", value = "", **Name = "staffSearchFilterName"** })

then you have to use

@Html.ValidationMessage("staffSearchFilterName")

Answer 3

If your @Html.ValidationSummary() call is in a Partial view, DON'T pass data into the partial view like this:

@Html.Partial("_YourForm", Model,  new ViewDataDictionary { { "Submit", true }})

Instead, add the key value pair to Html.ViewData collection first:

@{
    Html.ViewData.Add(new KeyValuePair<string,object>("Submit",true));
}

then call the partial view:

@Html.Partial("_YourForm", Model, Html.ViewData)

this will allow the ModelState to propagate to the partial view properly.

In controller custom error

 ModelState.AddModelError("test","test");

Summary:

 @Html.ValidationSummary(false, "", new { @class = "text-danger" })

Individual field:

  @Html.TextBoxFor(m => m.FieldName, new { @class= "form-control" })
  @Html.ValidationMessageFor(m => m.FieldName, "", new { @class = "text-danger" })
