I always have ViewModels for displaying data in Views and for the scenerios you mentioned, put logic in property defined in ViewModel

public class FunEventViewModel
    {
        public DateTime BlogDate { get; private set; }

        public FunEventViewModel(FunEventModel funEventModel)
        {
            this.BlogDate = GetBlogDate(funEventModel);
        }

         private DateTime GetBlogDate(FunEventModel funEventModel)
        {
            if (funEventModel.ModifiedOn.HasValue)
            {
                return funEventModel.ModifiedOn.Value;
            }
            else if (funEventModel.CreatedOn.HasValue)
            {
                return funEventModel.CreatedOn.Value;
            }
            return new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);
        }

}

Hi Vnhanet,

The easy answer is

In View, update from

@Html.EditorFor(model => model.CreateDate)

To

@Html.TextBox("CreateDate", model.CreateDate != null? model.CreateDate : DateTime.Now)

Hopefully, this answers your question.

Danny

Uppssss. sorry about it. Could you change from

@Html.TextBox("CreateDate", model.CreateDate != null? model.CreateDate : DateTime.Now)

To

@Html.TextBox("CreateDate", Model.CreateDate != null? Model.CreateDate : DateTime.Now)

I forgot that the model should be use capital M, so it should be Model.

Cheers,

Danny

After that, my view is:

        <div class="editor-label">
            @Html.LabelFor(model => model.CreateDate)
        </div>
        <div class="editor-field">
             @Html.TextBox("CreateDate", Model.CreateDate != null? Model.CreateDate : DateTime.Now)
             @Html.ValidationMessageFor(model => model.CreateDate)            
        </div>

but it made an error:
