                                                    {
                                                        de.Click.Url = Url.Action("HandleChanges");
                                                        de.Click.ExtraParams.Add(new Parameter
                                                        {
                                                            Name = "data",
                                                            Value = "#{Store}.getChangedData()",
                                                            Mode = ParameterMode.Raw,
                                                            Encode = true
                                                        }
                                                                                );
                                                        de.Click.ExtraParams.Add(new Parameter
                                                        {
                                                            Name = "scenarioId",
                                                            Value = Model.SID.ToString(),
                                                            Mode = ParameterMode.Raw,
                                                            Encode = true
                                                        }
                                                                                );                                                      
                                                    }
                                                                 )

Form the code behind on a condition i have to return a string to the client side.

How to pass this string in the return statement?
How to catch this statement at client side?
How to call a javascript function so as to pass this string?

Hi @PriceRightHTML5team,

What about this?

X.Js.Call("functionName", "the string");

It should be called within a controller action of DirectEvent.

Hi

X.Js.Call("functionName", "the string");

works fine when i call a function which has a simple alert() in it. But when i calling a external javascript function (which is my requirement) it gives js error saying function not found.

I have external css to applied for that js function

How to achive this?

[Daniil]

it gives js error saying function not found.

Is that function defined on the page? Please demonstrate how.

I have external css to applied for that js function

Hi,
I placed following code in my controller's action method

X.Js.Call("ShowMessage", "invalid data");

here ShowMessage is a js function defined in CommonJavascript.js

it gives js error saying "function not found."

[Daniil]

It means that the CommonJavascript.js is not loaded yet. Where is it defined?

A full test case is appreciated.

[PriceRightHTML5team]

CommonJavascript.js is in the Scripts folder of Asp.net MVC webproject

[Daniil]

Good.

How do you attach it to the page?

[PriceRightHTML5team]

The reference to that specific js was missing.

Now it is working fine.

Thanks for pointing it out.
