Question

I'm want to validate value of name from Create.cshtml and AddUser.cshtml page. working in mvc application

in create.cshtml

<div id="tab3" class="tab_content">

@Html.TextBoxFor(x => x.FirstTripStartTime, new { id = "minStartTime", @class = "smallTxtEntry3" })&nbsp;(HH:MM:SS)

</div>

in adduser.cshtml

<div>
  <td valign="top" class="nd_nor_ftd">Start Time<span class="mand">*</span></td>
                    <td>
                        @Html.TextBoxFor(x => x.StartTime, new { @class = "smallTxtEntry3" })&nbsp;(HH:MM:SS)

       <span>Add Frequency</span>

Answer 1

As you are talking about different pages, you can share state and values between them in*at least* 2 ways:

1. Save data in DB from one page and read from another (not so good, as need a request)
2. Save in local storage a value from one page and read it from another page (definitely better)

For easy data save/read on client side can have look on: amplify.js.

Answer 2

You can use the MVC Session object to persist server side data (without the need for a database, or relying on client side storage) and check the values client or server side.
