Binding data directly from model of asp.net mvc

Question

I developed a textbox control which shows rounded off data on blur and actual data on focus. currently this is being done using JS and value change has no relation with ASP.NET model.

Is it possible to add two properties to model and bind them to these events? ie, If I have A & B, on blur A should be bound and on focus B should be bound. And each time when user modifies B, the changed value should be reflected in A (after rounding off).

I checked many websites, but I couldn't understand any of it. Few of them are,

I'm assuming what you're after here is having both the rounded and actual data on post. If so, there's a better way than actually posting both. Just add a property to your view model that returns the rounded data:

public decimal Data { get; set; }

public int RoundedData
{
    get { return Convert.ToInt32(Math.Round(Data, 0)); }
}

But if user edits that, then he will see actual value on blur, not rounded one. right? – Prajwal May 10 '17 at 17:30
This has nothing to do with what's going on client-side. Presumably from your question, you already have that piece covered. – Chris Pratt May 10 '17 at 17:31
Actually, I'm searching for a way to avoid using any client side scripting. Is that possible? – Prajwal May 10 '17 at 17:44
No. Not if you want the user to have immediate feedback (focus/blur). That happens client-side and must be handled client-side. – Chris Pratt May 10 '17 at 17:47
Thanks. That what I wanted to know. :) Please update the answer. I'll mark it. – Prajwal May 10 '17 at 17:49
