C# date comparison MVC Razor

Issue:
I had a problem with a conditional test which was failing.  I was trying to compare two dates but the condition was not firing in my view.




claimPayments.Payment_Date.Value.ToString("dd-MMM-yyyy") == temp.ToString("dd-MMM-yyyy")


changed it to


claimPayments.Payment_Date.Value.Ticks.Equals(temp.Ticks)


This fixed the problem.  Using the ticks function gets around the issue of trying to match date formats.

DateTime DisplayFormat seems to have no effect (MVC5, Razor)

Issue:

I had declared in my model the following

[DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
public DateTime? AuditDate { get; set; }

  @Html.EditorFor(model => model.AuditDate, new { htmlAttributes = new { @class = "form-control" } })
           
But it was not working!

Then I noted that the Default Displayformat is defined to work with @Html.Display or @Html.DisplayFor and inorder to get it working with Editor controls you need to apply ApplyFormatInEditMode = true.

MVC Razor Syntax: Can't implicitly convert bool? to bool

Problem:

My model had several variables which were nullable Booleans.  My issue was how to bind them in the Razor syntax without getting an error.


I had tried
@Html.CheckBoxFor(model=>(bool) model.LengthConfinementLife)


which will compile but fails on a runtime error.


Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions.

Solution:

@Html.CheckBox("LengthConfinementLife", Model.LengthConfinementLife?? false)
@Html.Label("LengthConfinementLife", "My Dates are Flexible")
