[Solved] Rad Prometheous ComboBox control

[yuri]

Dear Telerik,
In your code library you published solution for the ComboBox and CheckBoxes in order to get multiselection.
I did the following:
1. Took your solution
2. Changed ComboBox to Prometheous ComboBox
As a result I do not see text against textboxes.

Moreover, if previously I could access individual check box using:
var id = document.getElementById(combo.Items[i].ClientID + "_CheckBox");
I cannot do this not as combo box item does not implement any ClientID or similar functionality.

Would you please explain how can I use Prometheous combobox with check boxes in order to implement multiselection.

Thank you very much,
Yuri

Dear Rosi,
Your example does work. Thanks a lot. The difference is that:
1. You do binding on the server side - on Page_Load. Why? With ASP.NET Combobox I should not do it if I declare my items in aspx file.
2. How to determine whether check box is checked or not on the client side (javascript code). You do it on the server side with method GetCheckedItems(). In my previous e-mail I showd how it could be done with ASP.NET combo.

Thanks a lot,
Yu

Hello Yuri,

Below are the answers of your questions.

1. DataBinding of RadComboBox "Prometheus" items is necessary when DataBinder.Eval method is used in the templates.

2. You can check are the checkboxes checked by the following way:

      function GetCheckedItems()
        {
            var combo = $find("RadComboBox1");
            var i = 0;
            for(i= 0;i<combo.get_items().get_count(); i++)
            {

                var id ="RadComboBox1_i"+i+"_CheckBox";
                alert(document.getElementById(id).checked);
            }
        }
        </script>

All the best,
