From / To date issue

[Taj]

Using datepicker to takr "To" and "From" date inputs in a MVC view . I need to make sure that users can't select To date value prior to From value. I am doing as follows


<%: Html.Telerik().DatePicker().Name("From").OpenOnFocus(true)%> 

<%: Html.Telerik().DatePicker().Name("To").Min(Model.From).OpenOnFocus(true)%> 

Getting an error on load of the page:

Server Error in '/' Application.

---

"date" cannot be null or empty.

I understand it's happening because my "To" field is empty, but what is the walk-around?

Hi There,

Still waiting for a solution

Hi,

Even if the FROM field is not empty, it is not reasonable to set its value as a min value for the TO field, because both can be changed client-side.

You should implement server validation similar to this one...

and also client validation by using the components' change event.

Thanks Demon for your reply.

I think I need to do as follows
1. if FROM date is empty, disable TO date
2. On Change of FROM date, enable TO date and  set TO date's Min value to FROM date

How can I do that?

It will be a good user experience if I can do the whole thing on client side.
