Hi,

I am using radlistbox. i added the items into radlistbox in client side. it is fine. but how to add attributes for the item?

var list = $find("<%= RadListBoxSource.ClientID %>");
                     var items = list.get_items(); list.trackChanges();
                     var item = new Telerik.Web.UI.RadListBoxItem();
                     item.set_text(txt);
                     item.set_value(val);
                     list.get_items().getItem().set_attributes().setAttribute('display_list') = "list1";
                     list.get_items().add(item);
                     item.select();
                     list.commitChanges();

Bold items i am not able to add attributes for this one.

Please let me know if you have any tips,

Thanks,
Dhamu,

Hello Dhamu,

Take a look at the following documentation.
RadListBoxItem client API

Thanks,

Hi Princy,

I am not clear about this example.

Please check my code,

<telerik:RadListBox
        runat="server" ID="RadListBoxSource"
        Height="200px" Width="200px"
        AllowTransfer="true" TransferToID="RadListBoxDestination" AllowReorder="false" DataTextField="uname" DataSourceID="SqlDataSource3"  OnClientItemDoubleClicked="setText" AppendDataBoundItems="true">
        <Items>
        <telerik:RadListBoxItem Text="All Items" Value="list1"  Selected="true"/>        
        </Items><ButtonSettings ShowTransferAll="false" ShowTransfer="false" />
    </telerik:RadListBox>

Code behind
-----------------
Protected Sub RadListBoxSource_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadListBoxItemEventArgs) Handles RadListBoxSource.ItemDataBound

        If TypeOf e.Item Is RadListBoxItem Then
            e.Item.Attributes("display_order") = i + 1
            e.Item.Attributes("display_list") = "list1"
        End If
        i += 1
    End Sub


Client side,
---------------
   var list = $find("<%= RadListBoxSource.ClientID %>");
                     var items = list.get_items(); list.trackChanges();
                     var item = new Telerik.Web.UI.RadListBoxItem();
                     item.set_text(txt);
                     item.set_value(val);               
                   list.get_items(order).add(item);                  
                   item.select();
                     list.commitChanges();

It is all working fine..
I am using two attributes in code behind. there is "display_order" and "display_list". so now i am adding value in client side how to set values for these attributes.

Please let me know,

Thanks,
Dhamu.

Hi dhamodharan,

After you add the attributes you need to find the item from the RadListBox client object and set the attributes values.
Here is an example:
