Hi Raju,

In the view, I only have this:

<div class="inputs">
                        @Html.LabelFor(model => model.Email, new { }, ":")
                        @Html.EditorFor(model => model.Email)
                        @Html.RequiredHint()
                        @Html.ValidationMessageFor(model => model.Email)
                    </div>

In your example, you are using this which I don't have in the view page so way to add onblur in html for me.

<input class="text-box single-line" data-val="true" data-val-email="Wrong email" data-val-required="Email is required." id="Email" name="Email" type="email" onblur="validateDomain(this)">
