Hello,

I am trying to use a RadListBox to display items that a user has selected on a RadGrid.

There is an instance where, on a button click, I am attempting to add 2000+ items to the radlistbox.  This is all being done in JavaScript.

When adding this many items, the browers (IE 8) displays a message stating that there is script being run on the page that is causing the page to not respond.  I believe this is being caused by having to add so many items to the RadListBox.

Is there a workaround for this, or another control that i can use to display selected items from the grid?  I need to keep this on client side in Javascript.

Here is the script that I am using to add items to the RadListBox (my radlistbox is named rlbSelectedContacts):

                            var rlbSelectedContacts = $find("<%=rlbSelectedContacts.ClientID %>");
                            if (rlbSelectedContacts)
                            {
                                    for (each item in my list of items to add) //this FOR loop could iterate thousands of times
                                    {
                                        var item = new Telerik.Web.UI.RadListBoxItem();
                                        if (item)
                                        {
                                            item.set_text(contactName);
                                            item.set_value(contactId);
                                            rlbSelectedContacts.trackChanges();
                                            rlbSelectedContacts.get_items().add(item);
                                            rlbSelectedContacts.commitChanges();
                                         }
                                    }
                             }

I'm still trying to understand how to move things around in a Date Time picker control. I have a little date box for text input, about a 10-15 px space to the date popup button and then 100 or so pixels to the little clock. HOW do I change where these items are located in the control. Example please!

Thanks,

I have a RadGrid with columns being added programatically in the page_load. Everything works but if I check a column the menu disappears and the column doesnt hide.
Any suggestions?

If I have more than one input manager on a page, how can I enable or disable them based on the selection of a dropdown box?  I want to do it client-side so there is no postback. Is that possible?

Here is my code sample: Multuiple Input Manager Sample

Hi,
In Recurrence, Hourly Frequency is selected, how can i validate if there is no input in the interval?

In what EVENT will i put or add an exception, so that i could catch the error of the empty interval?

Hi,
I have 2 drop down list.
DropDownList1 is put inside RadAjaxPanel, and i set the RadAjaxManager where DropDownList1 will update content of DropDownList2 so that the page don't post back when DropDownList1.SelectedIndexChanged is fired.
DropDownList2 is not inside RadAjaxPanel, because i want the post back to happen when DropDownList2.SelectedIndexChanged is fired. But in this case, it's not post back.
What should i do so that my DropDownList1 does not post back (and update DropDownList2 when DropDownList1.SelectedIndexChanged is fired) but my DropDownList2 is post back (when DropDownList2.SelectedIndexChanged is fired)?
Thanks!

When one clicks on the +/- button of the node, the node expands and the +/- changes to -.
When I programmatically expand the node, the node expands but the +/- remains +.

How do I address the +/- button in code to get it to behave?
