asp.net mvc - MVC3 - Input and Output value -

-

i learned mvc3 example haven't found i'm looking for. in asp.net webforms:

public void something() {     string = textboxa.text;     string b = textboxb.text;     textboxc.text = + b; }

how in mvc ? tried create actionresult don't want redirect view.

you might want @ client side i.e. using jquery etc. in mvc, has managed @ controller side updating required properties of viewmodel. viewmodel intern binded controls on actual view 

//model public class addviewmodel {     public int 1 { get; set; }     public int 2 { get; set; }     public int result { get; set; } } //controller public actionresult index() {     addviewmodel obj = new addviewmodel();     obj.one = 1;     obj.two = 2;     obj.result = obj.one + obj.two;     return view(obj); } //view @model mvcapplication3.models.addviewmodel @html.editorfor(model => model.one) @html.editorfor(model => model.two) @html.editorfor(model => model.result) <input type="submit" value="save" />
