I want to add a custom checkbox on the Upload window, checking/unchecking of which will decide something related to documents. Is that possible somehow?
RadFileExplorer does not offer functionality to modify the Upload dialog. Nevertheless, you can achieve this by adding a <CheckBox> element to upload dialog. You could use JavaScript and JQuery for the implementation.Here is the sample code.
Although the suggested JavaScript solution seems proper to me, you also may find useful the following forum thread, where such scenario has been discussed: Custom Upload File Fields.
All the best,
