Can we have a separate Listbox to hold the selected values

[Abhishek Dixit]

Hello Telerik Team,

 I want to use the RadComboBox as an Auto suggest control. It's working great, the addition I want is that can we have a separate ListBox just below the ComboBox to hold the selected values from the Combobox. So is that possible.
This will help me to help get the multiple parameters on a postback.

Regards,
Abhishek

Hi Abhishek,

I suggest you subscribe to OnClientSelectedIndexChanged event of RadComboBox and add items to the ListBox in its handler. I've attached a simple page demonstrating this approach. Please download it and give it a try.

Best wishes,

Happy New Year Telerik,

Its a shame filtering is not availble on the ListBox. That Listbox woiuld be so much better with it.
Ive looked at your code sample and its probably my best solution. Is it possible to populate a radlistbox using the combo box though?
Rather than a standard asp.net list box?

Many Thanks, Des

Hello des white,

Isn't the sample project provided by Yana useful to you in this case?

Can you please describe in more details what you mean by this:

All the best,

it would be useful if Yana used a RadListBox rather than the standard ListBox provided my microsoft.

Yana uses...

<telerik:RadComboBox>
</telerik:RadComboBox>

with

<asp:ListBox>
</asp:ListBox>

This would have been more useful is the javascript she provided was for use with a

<telerik:RadListBox>
</telerik:RadListBox>

Hello des white,

You can easily use RadListBox instead of plain ListBox. The principle is exactly the same, hook on the RadComboBox OnClientSelectedIndexChanged event, then grab the selected value, create new RadListBox item and insert it into the RadListBox. You can find detailed information regarding the RadListBox clienthttp://www.telerik.com/help/aspnet-ajax/listbox-client-side-basics.html API here.  Here is basic example code:

selectedIndexChangedHandler(sender, args)
{
    var value = *obtain the selected value*
    var item = new Telerik.Web.UI.RadListBoxItem(value);
    var listBox = $find("RadListBox1");
    listBox.trackChanges();
    listBox.get_items().add(item);
    listBox.commitChanges();
}

Sincerely yours,
