Having a RadCombobox on a form and assign a EmptyMessage later containing a diacritical character, the EmptyMessage is treated like it has been entered as a value.
So it will make a call to the webservice using that value which it should not do.

Code example:
        protected void TestLinkButton_Click(object sender, EventArgs e)
        {
            this.CountryComboBoxControl.EmptyMessage = "Bitte wählen Sie ein Land*";
        }

For the time being the following CSS workaround can be used:
CSS:
    <style type="text/css">
        .RadButton.rbSkinnedButton input {
            padding-left: 6px;
            padding-right: 10px;
            margin: 0;
        }
    </style>
ASPX:
        <telerik:RadComboBox ID="RadComboBoxDateTimeFilter" runat="server">
            <ItemTemplate>
                <telerik:RadButton ID="RadButtonApply" Text="Apply" AutoPostBack="false" runat="server" />
                <telerik:RadButton ID="RadButtonClear" Text="Clear" AutoPostBack="false" runat="server" />
            </ItemTemplate>
            <Items>
                <telerik:RadComboBoxItem Text="" Value="" Selected="true" />
                <telerik:RadComboBoxItem Text="" Value="" />
            </Items>
        </telerik:RadComboBox>

I have instances of using OnClientBlur on multiple RadComboBox controls, and if you tab quickly enough the event does not fire.  I've created an example which replicates what I see in the project I'm working on - two RadComboBoxes with the Blur event where I get the second to fire but not the first when tabbing from first to second to third (just another control w/o event).

This is causing issues where some validation is bypassed.

A couple observations:
- It will fire correctly if I wait long enough before tabbing out.
- If I pause on the second control after tabbing, then click somewhere, it sometimes then fires the Blur from the first control.
- I am using LoadOnDemand.  From my general observation it looks like it's potentially a race condition with the loading.

It gonna be cool if ComboBox display his picture with text, like the pic shows.

add ability for radcomboboxitem to expose the attributes collection for the selected item when client-side binding occurs via a webservice.  (based on support id 87724).  Currently only selected text and values are accessible when posted back.  The attributes related to the selected item are as important to provide proper context once on the server side.  Again, this only necessary for the selected item, not all items as I understand the ramifications to client side performance.

Version: 2014.3.1024 - NET 4.0 - Visual Studio 2012 Pro

The bug occurs when checkboxes are enabled and one or more items are set invisible on the server-side (Visible=false). Checked items are not persisted correctly between postbacks. I have included a sample project to show the incorrect behavior.

Steps to reproduce to problem:

1- Start the sample project
2- The first combobox has 10 items. The first one has been set invisible.
3- Check an item
4- Click the "Select" button
5- The wrong item is checked. The checked item change at every postback

Also, the RadComboBox control should automatically select the first visible item instead of the first item of the list. The second combobox of the sample projet shows this behavior.

Thank you for looking at this issue.

We have evaluated your controls for few days for the last 4 years now. And you still dont support check boxes and load on demand. (we keep getting the same response from your forms). There are other companies already do that. If you can include this feature in your future development that will be great. 

We can not use RadAutoCompleteBox control as the users do not what they are searching for. 

How come no one else asking for this. All what needed is to cache the values after the control is loaded. 

Thanks.

In Lightweight rendering mode, the drop-down arrow has cursor type 'text' instead of 'default' in Internet Explorer (11).
