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

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.

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

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.

Screencast: http://screencast.com/t/VTQrN9uOVrI9

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.

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>

When RadCombobox is inside fixed div element and is expanded it doesn't scroll as expected. The dropdown container should stay fixed as the combo's input element.

ComboBox keeps the dropdown aligned to either sides of input field.
If due to content overflow e.g in a small frame input field is placed slightly out of viewport then it would be better to check the boundaries if ScreenBoundaryDetection is enabled and keep the dropdown in view and not necessarily aligned with input.

From customer feedback:

Label display style is not taken into consideration when calculating the width of the combobox e.g. if the display style is block, the label and combo should be on separate lines. In terms they should be equally wide.

However currently the combo is squashed to a minimum width.
