[Solved] RadComboBox ItemsRequested if DropDown Image Clicked

[jgig]

I want to set up my RadComboBox dropdown where it does not appear unless they click the dropdown image. I also have to LoadonDemand because I will be using Linq to read a XML file with over 3000 airport Codes. Additionally I will have several of these in a repeater. At least 2 for round trip and many more for a multiple stop itinerary

So if the user types text in the textbox I want the dropdown to stay closed. If they click the dropdown I want to Load Items on Demand and I will filter those by the text they have entered in the textbox. also if the drop down is aleady OPEN and they modify the text refilter the Items. I know this is different because it is usually one way or the other. Is this possible?

Hi there,

I suggest you subscribe to OnClientDropDownOpening event and in its handler cancel the opening if the input field of the combo is clicked like this:

<script type="text/javascript">
    function OnClientDropDownOpening(sender, args)
    {
        var ev = args.get_domEvent();
        if(ev == null || args.get_domEvent().target.className == "rcbInput")
            args.set_cancel(true);
    }
</script>

I hope this helps.

PERFECT!

that is exactly what I was trying to get accomplished. (a little surprised there wasnt a cleaner way where your not using a class name to accomplish this though) My combobox is more for help than anything. Now if they want to use it they can but it wont hinder the user from filling out the form rapidly

this apparently is not supported anymore with the new DLL - args.get_domEvent().target.className

Is there a  better way so this will continue to work. I tried setting ShowDropDownOnTextboxClick="false" but when I start typing it still opens the drop down. I only want to open the drop down IF they click the arrow.

I am using Telerik.Web.UI, Version=2009.2.701.35,

thanks for you help

Hello jgig,

I suppose the method was working in Firefox only with the old version. Please use this one for both IE and Firefox:

<script type="text/javascript">
    function onDropDownOpening(sender, args) {
        var ev = args.get_domEvent();
        if (ev) {
            var target = ev.target || ev.srcElement;
            if (target.id == sender.get_id() + "_Input")
                args.set_cancel(true);
        }
        else args.set_cancel(true);
    }
</script>

I hope this helps.
