Cannot add items to RadCombobox inside a RadWindow

[Mark]

Hi

I am using RadAjax 2008 Q2 controls.

In Javascript I am able to successfully get a reference to a RadCombobox in a pop-up dialog.

While I can clear the items, when I try to add a RadComboboxItem I get the following error:

        "htmlfile: Invalid argument."


Below is my Javascript code:

    var contentFrame = gwinEventDetails.GetContentFrame().contentWindow;
    var cboState = contentFrame.$find(contentFrame.gDLGcboVenueStateID);
    var cboStateItem = new Telerik.Web.UI.RadComboBoxItem();
    
    // Clear state combobox
    cboState.clearItems();
    cboStateItem.set_text(SELECT_OPTION);
    cboState.get_items().add(cboStateItem);    --ERROR!!--
    cboStateItem.select();


Hope this is enough information.


Kind regards

Hello Mark,

You can solve the problem by following the steps:

1. Define a method  for adding items to the combo in the content page of RadWindow.

For example:

    function AddNewItem()
    {

        var combo = $find("RadComboBox1");
        var comboItem = new Telerik.Web.UI.RadComboBoxItem();
        comboItem.set_text("aaa");
        combo.get_items().add(comboItem);
        comboItem.select();

    }

2.Call this method from the parent window by the following way:

 gwinEventDetails.GetContentFrame().contentWindow.AddNewItem();
