        Does anyone know of a way to validate a RadUpload that is located inside of a RadDrid's FormTemplate via JavaScript.  I want to validate these two things: 1) That the RadUpload contains a file. 2) That the RadUpload's File contains a valid extensions.  I have looked at some tutorials for Client-Side validation, but none show how to validate a control within the FormTemplate.

    Thanks in advance,

    Hi Mahesh,

    You can check whether the upload control has a file uploaded with the following code:
    if ($telerik.findControl(document, "RadAsyncUpload1")._uploadedFiles.length > 0)

    As for the file extension validation, you can use RadAsyncUpload's AllowedFileExtensions property. A demonstration on how to use the property can be found in the following demo:
