Hello, Premkumarm,

Currently, the buttons of the Upload can be customized only with CSS:

.k-upload .k-upload-button {
  color: blue;
}

If the requirement is to modify the buttons by adding icons and changing the entire appearance, I can convert this to an official public feature request, and based on its popularity we will plan it accordingly.

--------------------------------

Also, I see that the upload button is next to the Upload wherein our rendering the button is under the Upload. This can be achieved by rendering a custom button next to the Upload and uploading the files programmatically. This will require using a controlled mode to keep the files in the state and the getRawFile method to get the real files. This is a short example showcasing a possible approach:

- Controlled mode: https://www.telerik.com/kendo-react-ui-develop/components/upload/modes/#toc-controlled-mode

- Get raw file method: https://www.telerik.com/kendo-react-ui-develop/components/upload/api/UploadFileInfo/#toc-getrawfile
