[Solved] DatePickerFor does not use value from model

[Dave]

Originally posted in the Calendar forum:

I am passing in dates to action method in the route like this:
http://mydomain/{controller}/{action}/2012-06-19

The action method receives this value in a "startDate" parameter on the action method and it is converted into a DateTime. So far so good.

Next I construct a ViewModel that contains a StartDate property of type DateTime. The date value passed into the action method is set as the value of the ViewModel's StartDate property. This ViewModel is passed to the View.

In my view I want to display a DatePicker using this date so I have the following:

@(Html.Telerik().DatePickerFor(x => x.StartDate)

.Min(Model.VitalSign.MinimumDate))

I would expect that the DatePicker's value would be taken from the value in the ViewModel. However, the DatePicker control shows the date as "2012-06-19" instead, presumably taking the value from the RouteValues collection instead.

How do I get the DatePickerFor method to use the value from my ViewModel? I tried .DatePicker().Name("startDate").Value(Model.StartDate) but it still shows "2012-06-19" in the DatePicker control.

Hi Dave,

Generally speaking the DatePicker tries to get the value from the ModelState. In your case you will need to either use different names for the datepicker/modelproperty or you could clear the ModelState manually with the following code invoked before rendering the DatePicker.

@{  ModelState["thename"]=null;
    // or
    ModelState.Clear(); }

I hope this helps.
