[Solved] Get muti-value...

[Minh]

Dir sir,
I have a problem you need help,
in demo ComboBox / Related ComboBoxes :
function LoadCities(combo, eventArqs)
{    
    var item = eventArqs.get_item();
    citiesCombo.set_text("Loading...");
    // this will fire the ItemsRequested event of the
    // cities combobox passing the countryID as a parameter
    citiesCombo.requestItems(item.get_value(), false);                    }
I want to get more value of comboContinent, then how?

Thanks for support,
Brgs,

Hello,

You can add a custom Attribute for the RadComboBoxItem in order to other datafield values, so as to retrieve the value in SelectedIndexChanged event.

C#:

protected void RadComboBox1_ItemDataBound(object sender, Telerik.Web.UI.RadComboBoxItemEventArgs e)
{
    DataRowView dataSourceRow = (DataRowView)e.Item.DataItem;
    //set custom attributes from the datasource:
    e.Item.Attributes["CustomAttribute"] = dataSourceRow["CustomDataField"].ToString();
}
protected void RadComboBox1_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
{
    String ID = e.Text;
    String Price = RadComboBox1.SelectedItem.Attributes["CustomAttribute"];
}

You can also refer to the following document to understand how to add cudtom attributes for the combobox items:
