    text
    copied!<p>in my controller i have Create action for view .i want to show validation exception with ModelState .but it does not work truly.</p> <pre><code> /// &lt;summary&gt; /// GET: /AgentPosition/Create /// &lt;/summary&gt; /// &lt;param name="model"&gt;The model.&lt;/param&gt; /// &lt;returns&gt;&lt;/returns&gt; public override ActionResult Create(Models.AgentPosition.AgentPositionModel model) { if (model.PositionContacts == null || model.BankAccountDetails == null) { if (model.PositionContacts == null) { this.ModelState.AddModelError("PositionContacts",Resources.Resource.MustInputPositionContact); } if (model.BankAccountDetails == null) { this.ModelState.AddModelError("BankAccounts", Resources.Resource.MustInputBankAccountDetail); } return this.View(model); } return base.Create(model); } </code></pre> <p>in My View </p> <pre><code> @using (this.Html.BeginForm("Create", "AgentPosition", FormMethod.Post, new { enctype = "multipart/form-data" })) { this.Html.ValidationSummary(true); &lt;div&gt; @this.Html.Partial("BankAccounts", this.Model) @this.Html.ValidationMessageFor(model =&gt; model.BankAccountDetails) &lt;/div&gt; &lt;div&gt; @this.Html.Partial("PositionContacts", this.Model) @this.Html.ValidationMessageFor(model =&gt; model.PositionContacts) &lt;/div&gt; </code></pre> <p>}</p> <p>I give only one Exception Validation from ModelState(First Model Error) in View.</p> <p>I find the answer. I must change this code :</p> <pre><code>this.ModelState.AddModelError("BankAccounts", Resources.Resource.MustInputBankAccountDetail); </code></pre> <p>TO </p> <pre><code>this.ModelState.AddModelError("BankAccountDetails", Resources.Resource.MustInputBankAccountDetail) </code></pre> <p>because in MVC we must have same PropertyName in Model and it in dictionary that save exception in modelstate. </p>

An individual column
