    I have to validate my RadComboBox with custom validator and if the validation is failed i have to set the style as the textbox image attached. Pls. Guide me how to achieve this.
    Additional info: in text box we have the following code

    textbox._invalid = true;

    What is the similar one for RadComboBox.

    I am not sure about whether RadComboBox supports InvalidStyle like textbox control. But one work-around you can try is showing the image in the input field of combobox. The approach is described in teh code library.
    Show the selected Item image in input
