    While the user upload files to the server using RadUpload, Is there any mechanism to perform file validation process for a particular file extension alone?

    Hi Berkman,

    It is possible to perform custom validation for a particular file extension. You can write the necessary code to perform custom validation in the ValidatingFile server-side event. Please have a look into the following C# code which performs a custom validation for ZIP files.

    private void RadUpload1_ValidatingFile(object sender, ValidateFileEventArgs e)
        // check only the zip files 
        if (e.UploadedFile.GetExtension().ToLower() == ".zip")
            //Your Custom Validation Code 
            // zip files must not be validated for file size by the internal validator   
            e.SkipInternalValidation = true;
