    Can somebody help me in showing the message that particular file type is not valid while selecting particular file type in the Open window.

    For Example there is  a property AllowedFileExtensions , is there any way to stop the user from selecting particular file type?



    radU:RadUpload ID="radEvaluationFileupload" runat="server" Skin="Vista" Width="150px" InitialFileInputsCount="1" AllowedFileExtensions=".doc,.txt"



    ControlObjectsVisibility="None" TargetPhysicalFolder="C:\UploadFiles" SkinsPath="~/RadControls/Upload/Skins"



    MaxFileInputsCount="1" />
