I get it:)

Here's my configuration for now:

Code:

---

string DisplayField = "Name";
string ValueField = "Id";
string EmptyText = "-- empty --";
string EmptyValue = 0;
Ext.Net.ComboBox combo = new Ext.Net.ComboBox();
Ext.Net.Store store = new Ext.Net.Store();
                store.ID = this.ID + "_Store";
                Ext.Net.JsonReader reader = new JsonReader();
                combo.DisplayField = DisplayField;
                combo.ValueField = ValueField;
                combo.EmptyText = EmptyText;
                combo.EmptyValue = EmptyValue;
                reader.Fields.AddRange(new List<RecordField>{new RecordField(ValueField, RecordFieldType.Int), new RecordField(DisplayField, RecordFieldType.String)});
                store.SortInfo.Direction = SortDirection.ASC;
                store.SortInfo.Field = DisplayField;
                store.Reader.Add(reader);
                reader.IDProperty = ValueField;
                Ext.Net.HttpProxy proxy = new Ext.Net.HttpProxy();
                proxy.Url = "~/ComboHandler.cs";
                proxy.Method = HttpMethod.POST;
                proxy.Timeout = 10000;
                store.Proxy.Add(proxy);
                store.AutoLoad = false;
                store.BaseParams["session_name_combobox"] = store.ID;
                string jsonParams = JSON.Serialize(searchParams);
                store.BaseParams[store.ID + "_searchparams"] = jsonParams;
                combo.TriggerAction = TriggerAction.All;

1 more issue happend how to load only 1 value to combobox on server side:

Code:

---

object o = Activator.CreateInstance(type,new object[]{1,null};//type is System.Type of my BLL Object
((MMPControls.Web.ComboBoxWithAddFeature)control.Value).Store.AddRecord(o);//here I got exception JsonSerializationException do I need serialize this 'o' element?

---

Ok, thanks.

I would try to call this code from a server just after adding a new item.

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");

but how to get this combobox from iframe page? it is on parent page of window but save is make in iframe mode inside this window:(

Yes, there is no way to access a parent page from an iframe in code behind.

But, fortunately, you can use this JavaScript code on a client (within an iframe page) after adding a new item.

Code:

---

var combo = parent.ComboBox1;

combo.getStore().reload({
    callback: function () {
        combo.setValue('value');
    }
});

var combo = parent.#{ComboBox1}

is it correct?

No, it won't work.

#{} is actual on the page only where the control is presented.

so i need to somehow pass to the iframe clientId of control?

you have idea what is the best way to do that mb? I could do this by queryString but not sure is it the best approach

Is there a possibility to have several same ComboBoxes on the parent page?

There is such possibility in my case. Because combobox is only part of my custom server control.

To be clear every my control has his own combobox with store and button.

So, a static id is not an option.

Then yes, you shoud, probably, pass this a parameter to an iframe.

Maybe, there is a better solution. I would investigate a sample if you could provide.
