    [CLOSED] Dynamic Store: undefined error at client side

    Hi folks,

    this piece of code ...

            private void Core_BuildStore(ComboBox o)
        {          
            JsonReader j = new JsonReader(); 
            j.Fields.Add("Key", RecordFieldType.Int);
            j.Fields.Add("Text", RecordFieldType.String);
            j.Fields.Add("ValueCode", RecordFieldType.String);

            Store xStore = new Store();
            xStore.ID = "Store_WDL_FICH";
            xStore.Reader.Add(j); 
            xStore.DataSource = my dynamic List<T> ; 
            xStore.DataBind();

            o.ValueField = "Key"; // "ValueCode";
            o.DisplayField = "Text";
            o.Store.Add(xStore);
        }
    raises error "undefined Store_WDL_FICH" at client side:

    Store_WDL_FICH.callbackRefreshHandler(response, {serviceResponse: {success:true,data:{data:[{"Key":0,"Text":"PLANTILLA AUTORIZADORES.HTML","ValueCode":"PLANTILLA AUTORIZADORES.HTML"},{"Key":1,"Text":"PLANTILLA USUARIOS.HTML","ValueCode":"PLANTILLA USUARIOS.HTML"}], total: 0}}}, Store_WDL_FICH, o.eventType, o.action, o.extraParams)
    May you help me what is wrong?

    Cheers!

    Hi,

    Is it during a DirectEvent?

    Do you render a ComboBox?

    What exactly is the requirement?

    Daniil,

    This is raised from a button DirectEvent. It first calls this code and afterwards the previous one:

                   else if (typeof(C) == typeof(ComboBox))
                {
                    ComboBox o = field as ComboBox;
                    o.FieldLabel = "WDL_FICHE;
                    o.EmptyText = "Seleccione ...";
                    o.AllowBlank = false;
                    o.IndicatorIcon = Icon.BulletRed;
                    o.IndicatorTip = "";

                    if (IsID == true)
                    {
                        o.Attributes.Add("onfocus", "this.blur()");
                        o.ReadOnly = true;
                    }
                    else
                    {
                            o.Attributes.Remove("onfocus");
                            o.ReadOnly = false;
                    }

                       Core_BuildStore(o);
                }
            }   // else if (typeof(C) == typeof(ComboBox))
    Requeriment is dynamically build the combobox and the store (this one is an Enumerable<specific known object>

    Cheers

    Please look at the example.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void RenderComboBox(object sender, DirectEventArgs e)
    {
        Store store = new Store()
        {
            ID = "Store1",
            Reader =
            {
                new ArrayReader()
                {
                    Fields =
                    {
                        new RecordField("value"),
                        new RecordField("text")   
                    }   
                }
            }
        };
        store.DataSource = new object[] 
            { 
                new object[] { "1", "item1" },
                new object[] { "2", "item2" },
                new object[] { "3", "item3" }
            };
        store.DataBind();

        ComboBox c = new ComboBox();
        c.Store.Add(store);

        this.Form.Controls.Add(c);

        c.Render();
    }
