    I am using Radasyncupload to upload .doc files in my website. I want the radasyncupload to enable uploading files with .doc extension only. If the user selects other file format, i want the control to display an alert like Unsupported file format. Can anyone help me with sample code?

    Thank you,

    Hello Teena,

    You can set the AllowedFileExtensions property of the RadAsyncUpload to ".doc" so that the user wont be able to select files with extensions other than .doc. When you set this property, files with other extensions wont be displayed in the File browser window.

    RadAsyncUpload provides client-side event called OnClientValidationFailed. It is fired when the selected file has invalid extension or its size is higher than the MaxFileSize property.

    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions="doc" OnClientValidationFailed="OnClientValidationFailed">

    <script type="text/javascript">
        function OnClientValidationFailed(sender, args) {
            alert("Unsupported File Format");
