[CLOSED] ListItems / ComboBox - value is always a String?

[wagger]

Hello,

the ComboBox.Value is of type object, but when I get the value it is a string even though I do not put in a String then loading the Store.

If you look at ComboBox.SelectedItem.Value, "Value" is of type String and that comes from the fact the SelectedItem is of Type ListItem, and ListItems Value-property is String.

When I add data to my Store, that is by a ComboBox, I add an array of object[], like this:

  List<object> myStoreObjects = new List<object>();
            foreach (SomeObject cp2 in listOfObjects)
            {
                myStoreObjects.Add(new object[] { cp2.Id, cp2.ObjectName });
            }

The Id property is an uint, and ObjectName a string. This is the Store:

<ext:Store ID="Store_SomeObjects" runat="server" AutoDataBind="true" AutoLoad="true" >
    <Reader>
        <ext:ArrayReader>
            <Fields>
                <ext:RecordField Name="SomeObjectId" />
                <ext:RecordField Name="SomeObjectName" />
            </Fields>
        </ext:ArrayReader>
    </Reader>
</ext:Store>

So I would like to get the uint back when I check what is selected in the ComboBox, but now I get a string. How do I get my real object? To convert string to uint is easy, but what if I have a complex custom object?

Is it always gonna be String, and I have to parse that string (JSON??) somehow?

Ted

Hi wagger,

Could you clarify how do you imagine a Unit instance in client side JavaScript? There is no such class in JavaScript, you know.

So, ArrayReader passes a Unit instance to client as a string: "100px", etc., but it doesn't remember the type of this instance.

A .SelectedItem.Value comes from client side as a string.

Please use Unit.Parse().

Unit.Parse(this.ComboBox1.SelectedItem.Value)
