[CLOSED] Validation form

[SuperBolt]

Hi!

I have code

X.Window()
              .ID("wndModule")
              .Icon(Icon.Cog)
              .Modal(true)
              .Layout(LayoutType.Fit)
              .Items(
                  X.FormPanel()
                      .ID("formModule")
                      .Layout(LayoutType.Form)
                      .Frame(true)
                      .Items(
                       X.TextField()
                              .AllowBlank(false)
                              .ID("text_moduleName")
                              .FieldLabel("Module name),

..... //and other
                      )
                      .Buttons(
                          X.Button()
                              .ID("btnUpdateModule")
                          .DirectEvents(de =>
                          {
                              de.Click.Before = "validationWindow";
                              de.Click.Url = Url.Action("UpdateModule");
                              de.Click.ExtraParams.Add(new Parameter { Name = "moduleId", Value = "#{hid_moduleId}.getValue()", Mode = ParameterMode.Raw });
                             
                          })
                          
                      )
              )

 
var validationWindow = function () {
            return this.up('form').isValid();
        }

If I used function validationWindow - it's work

But if I use

de.Click.Before = "this.up('form').isValid()";   - it's not worked

Why is this happening?

I use ext.net mvc 3.3

Thanks!

Hello @SuperBolt!

The .Before property receives a reference to a function, so it can't really receive code.

Usually listener event handlers have either a .Fn (which is equivalent in parameter to the .Before you shown) and also a .Handler which receives actual JavaScript code. In your case, it is a direct event -- server side -- so it really works differently.

Additionally, in the example you tried, you just run .isValid() and not really returned anything. But it would not be working unless you wrap your code in a function. For example this should just work:

de.Click.Before = "function() { this.up('form').isValid(); }";

Hope this helps!
