    Dear Telerik,

    I have the following AutoCompleteBox:

    <td style="width: 150px; white-space:nowrap">
    <telerik:RadAutoCompleteBox ID="MachineWORadAutoCompleteBox" runat="server"
    TextSettings-SelectionMode="Single" MinFilterLength="2" DropDownWidth="200px"
    <WebServiceSettings Path="FeedbackForm.aspx" Method="LookupMachineWorkOrder" />

    <asp:RequiredFieldValidator ID="MachineWORadAutoCompleteBoxValidator" ValidationGroup="Save"
    runat="server" Display="Dynamic" ControlToValidate="MachineWORadAutoCompleteBox" ForeColor="red" ErrorMessage="*"></asp:RequiredFieldValidator>

    With a required field validator, the validation is triggered the validation itself works fine the problem I get is that the Error message is wrapped to the next line even though the style tag explicitly says "no wrap". See attached picture as an example of what.

    Form looking online the autocompletebox is wrapped around update panels and using an Ajax Manager you can specify if you want to render inline, I tried this out but it didn't have any effect.

    Any ideas?

    The wrapper of RadAutoCompleteBox control is a block element (div), This is the reason why the text (*) after this element wraps to the second line. The second reason is, that width of the radAutocompleteBox is set to 160 pixels and your <td> wrapper  is only 150 pixels width. to fix also this issue, we reset the width of the radSutoCompleteBox by width: auto. Please, apply the following to fix the issue:
    .RadAutoCompleteBox {
        display: inline-block;
    html .RadAutoCompleteBox {
        width: auto;
    .validator {
        vertical-align: top;

    Where .validator is CSS class added to asp validator
    <asp:RequiredFieldValidator CssClass="validator"

    We are sending you this video with testing and fixing the issue. Please, find also a sample project in the attachment.
