Setting IsSeparator using WebService

[Bob]

Hello Telerik Team,

I have a client side Combo box that I am populating from a Web Service.  I would like to use the 'IsSeparator' functionality to populate the combo box with Separator items.

Is this possible using JSON results from the server?

Thanks

Bob

Hello Bob,

Please accept my apology for the delayed reply.

I understand the issue that you describe, but I am afraid that IsSeparator property is not serialized.

However in your web method you can use the custom Attributes collection and add the IsSeparator property value as additional attribute to each item:

RadComboBoxItemData itemSeparator = new RadComboBoxItemData();
itemSeparator.Text = "separator item";
itemSeparator.Value = "separator item";
itemSeparator.Attributes["IsSeparator"] = true;
result.Add(itemSeparator);

Then at client-side you handle OnClientItemsRequested event, obtain the attribute value and set isSeparator accordingly.

<telerik:RadComboBox runat="server" ID="RadComboBox1"
    OnClientItemsRequested="OnClientItemsRequestedHandler">

function OnClientItemsRequestedHandler(sender, eventArgs)
{
   var items = sender.get_items();

   for(var i = 0; i < items.get_count(); i ++)
   {
        var item = items.getItem(i);
        if(item.get_attributes().getAttribute("IsSeparator"))
            item.set_isSeparator(item.get_value());
   }

}

Feel free to contact us if you have additional questions.

All the best,

Thanks Kalina,

I did not see the set_isSeparator Client API!  That's great news as that is what I was prepared to do...
