    is there a way to set the dropdown width for a text box with autocomplete programmatically.
    In my case I have a narrow TextBox. When there are too many entries for selection a scroll bar overlays the items.
    Please see the attached images.
    Thank you for any hint.
    Regards Roberto

    Hello Roberto,

    As far as I know it is not possible to change the AutoComplete DropDown Width. The RadTextBox contains at it's heart a HostedTextBoxBase which is inherited from Microsofts own TextBox which is providing the AutoComplete functionality. The Microsoft API for TextBox does now allow for access to the AutoComplete Drop Down.

    Hope that helps

    Richard is correct. Our RadTextBox control wraps the generic TextBox provided with the .NET and uses its auto complete mechanism, and there is no way you can access the auto complete dropdown. A quick Google search shows some workarounds though (note that these have not been tested and are not supported by Telerik):



    Hope this.

    All the best,
