    [CLOSED] how to binddata to ext:combobox in codebehind with datasource? 

    <ext:ComboBox ID="cb_VouchClassCode" InputWidth="60" runat="server" Cls="mr5">
                                            
</ext:ComboBox>
    var li = new Ext.Net.ListItem {Text = "car", Value = "c"};
cb_VouchClassCode.Items.Add(li);
    through above code can do this , but I wonder if there is other way to do this as gridpanel's datasource property?

    Hi @tobros,

    Welcome to the Ext.NET forums!

    You should deal with a ComboBox's Store.

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

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.ComboBox1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { "1", "Item 1" },
                new object[] { "2", "Item 2" },
                new object[] { "3", "Item 3" }
            };
        }
    }
</script>

<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        <ext:ComboBox 
            ID="ComboBox1" 
            runat="server" 
            DisplayField="text" 
            ValueField="value">
            <Store>
                <ext:Store runat="server">
                    <Model>
                        <ext:Model runat="server">
                            <Fields>
                                <ext:ModelField Name="value" />
                                <ext:ModelField Name="text" />
                            </Fields>
                        </ext:Model>
                    </Model>
                    <Reader>
                        <ext:ArrayReader />
                    </Reader>
                </ext:Store>
            </Store>
        </ext:ComboBox>
    </form>
</body>
</html>

    <ext:ComboBox ID="cb_VouchClassCode" Editable="False"   InputWidth="120" runat="server" DisplayField="VouchClassName" ValueField="VouchClassCode" Cls="mr5" AutoSelect="True">
                                            <Store>
                                                <ext:Store runat="server" ID="store_VCC">
                                                    <Model>
                                                        <ext:Model runat="server" IDProperty="VouchClassCode">
                                                            <Fields>
                                                                <ext:ModelField runat="server" Name="VouchClassCode"></ext:ModelField>
                                                                <ext:ModelField runat="server" Name="VouchClassName"></ext:ModelField>
                                                            </Fields>
                                                        </ext:Model>
                                                    </Model>
                                                    
                                                </ext:Store>
                                            </Store>
                                            
</ext:ComboBox>
                List<Cwzz_VouchClass> ll = vouchClassService.VouchClasses();
            store_VCC.DataSource = ll;
            store_VCC.DataBind();

    Please define the following for the ComboBox.
    <SelectedItems>
    <ext:ListItem Index="0" />
</SelectedItems>
    The AutoSelect is for other thing.
