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

[ViDom]

Please provide us with the Store's configuration. A solution can depend on it.

I get it:)

Here's my configuration for now:

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:

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?
