[CLOSED] Combobox in PropertyGrid

[bakardi]

I have Combobox in PropertyGrid. Trying to add items to it, but nothing appears in combobox:

 <ext:PropertyGrid ID="pgDocumentProperties" runat="server" Width="250">
                            <Source>
                                <ext:PropertyGridParameter Name="Document Type" Value="">
                                    <Editor>
                                        <ext:ComboBox ID="cbDocumentType" runat="server">

        public void FillProperties()
        {
            cbAreaCodeStore.DataSource = DocumentHandler.Instance.GetSTPProjectAreaCodes();
            cbAreaCodeStore.DataBind();

            cbDocumentTypeStore.DataSource = DocumentHandler.Instance.GetSTPDocumentTypes();
            cbDocumentTypeStore.DataBind();

            cbOriginatorStore.DataSource = DocumentHandler.Instance.GetSTPOriginators();
            cbOriginatorStore.DataBind();

            cbIDCodeStore.DataSource = DocumentHandler.Instance.GetSTPDocumentIDs();
            cbIDCodeStore.DataBind();
        }

Fill properties executed and all handlers returned data.

Hi,

Please see the example.

Example

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

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

<script runat="server">
    protected void Populate(object sender, DirectEventArgs e)
    {
        this.Store1.DataSource = new object[] 
        { 
            new object[] { "1", "mode 1" },
            new object[] { "2", "mode 2" },
            new object[] { "3", "mode 3" }
        };
        this.Store1.DataBind();
    }

So, I cant use IList<someobject> to init store of Combobox in PropertyGrid?

[Daniil]

You can.

Please modify my sample to reproduce your problem.

[bakardi]

I have class:

public class STPDocumentID: DomainObject<int>
    {
          #region Constructors
        /// <summary>
        /// This is a placeholder constructor for NHibernate.
        /// </summary>
        protected STPDocumentID() { }
        #endregion
        #region Properties

        public virtual string Code { get; set; }
        public virtual string Description { get; set; }
        #endregion
    }

I have combobox with store:

 <ext:PropertyGrid ID="pgDocumentProperties" runat="server" Width="250">
                            <Source>
                                <ext:PropertyGridParameter Name="ID Code" Value="">
                                    <Editor>
                                        <ext:ComboBox ID="cbIDCode" runat="server">
                                              <Store>
                                                  <ext:Store ID="cbIDCodeStore" runat="server" DisplayField="Code" ValueField="ID">

I have init code, which I called on afterrender of main panel.

 cbIDCodeStore.DataSource = DocumentHandler.Instance.GetSTPDocumentIDs();
            cbIDCodeStore.DataBind();

DocumentHandler.Instance.GetSTPDocumentIDs(); return 8 items of STPDocumentID type. Nothing appears to be in combobox.
