ComboBox data binding

[AlexMaslakov]

protected void Page_Init(object sender, EventArgs e)
        {
            taxingTypeStore.DataSource = GetTaxingTypes(); //returns Dictionary<int, string> which has values
            this.taxingTypeStore.DataBind();
}

 <div>
                        <b>Taxing Type</b>
                        <ext:ComboBox ID="ddlTaxingType" runat="server" StoreID="taxingTypeStore" ValueField="Key" DisplayField="Value" />
                        <ext:Store ID="taxingTypeStore" runat="server">
                            <Reader>
                                <ext:JsonReader IDProperty="Key">
                                    <Fields>
                                        <ext:RecordField Name="Key" />
                                        <ext:RecordField Name="Value" />
                                    </Fields>
                                </ext:JsonReader>
                            </Reader>
                        </ext:Store>
  </div>

I wonder why the data doesn't show. But taxingTypeStore has the data!

Store doesn't support Dictionary for binding

[AlexMaslakov]

Which data types does the Store support? Does it support List<Tuple<int, string>>?

Hi,

I have similar problem:

I have a combobox in a user control and i populate the combobox from database. But when i add the line

cmbbxStore.DataBind();

it just stucks. Nothing happens.

My code is:

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
            Populate();
    }

    protected void Populate()
    {
        cmbbxStore.DataSource = // A DataTable with fields (ID, Name)
        cmbbxStore.DataBind();
    }
</script>

<ext:ComboBox runat="server" FieldLabel="Program" ValueField="ID" DisplayField="Name" QueryMode="Local">
    <Store>
        <ext:Store runat="server" ID="cmbbxStore">
            <Model>
                <ext:Model runat="server" ID="storeModel" IDProperty="ID">
                    <Fields>
                        <ext:ModelField Name="ID" />
                        <ext:ModelField Name="Name" />
                    </Fields>
                </ext:Model>
            </Model>
        </ext:Store>
    </Store>
</ext:ComboBox>

When i remove the DataBind(), my combobox shows 10 items like this : {Name}. Here, "10" is the number of records in my lookup table.


Where is my problem, please?

Thank you.
