[CLOSED] Way to tell store to reaload data but only if circumstances are met

I see you have an access to the ComboBox in the Button's Click DirectEvent hanlder.

So you can generate JavaScript in this handler and pass it to a client to execute this way:

X.Js.AddScript("script");

Or define a JavaScript function and call it this way:

X.Js.Call("reloadComboBoxAndSetValue", combo.ClientID, "value");

What do you mean i can pass Javascript to client?
Do you mean that i can pass some javascript to iframe this way?

Could you provide sample where should I do it?

Hello!

I think @Daniil wants to say that you can combine server data with JS function.
For example, you have following JS function which reloads store and sets ComboBox's value:

var reloadComboBoxAndSetValue = function() {
	var combo = parent.ComboBox1;
	 
	combo.getStore().reload({
		callback: function () {
			combo.setValue('value');
		}
	});
}

And then instead of this Server code:

Store store = this.ComboBox1.GetStore();
store.AddListener("load", string.Format("function () {{ {0}.setValue('{1}'); }}", this.ComboBox1.ClientID, "value"), null, new HandlerConfig() { Single = true });
store.Call("reload");

You can call your JS function from Server side in this way:

X.Js.Call("reloadComboBoxAndSetValue", combo.ClientID, "value");

Could you please specify where should I do this exactly? my understanding of integrating javascript and server control is really low:(

need I use:

X.Js.Call("reloadComboBoxAndSetValue", combo.ClientID, "value");

on button inside iframe? And this Js function should be added in my serverControl prerender event or where?

[Daniil]

In your case it would be easy to use:

X.Js.AddScript("script");

And yes, you should call it from the Button's Click DirectEvent handler.

ok but I still can't understand how script will know what value set in my combobox after I add some in iframe?

I'm a really beginer in Ext Js so such a script will be at level extra hard i assumed for me :(

Where does you add a new item from the iframe in your sample?

[Daniil]

Please post a piece of code where you do that.
