How to dynamically show a fileUpload control within a datagrid row on row select or SelectedIndexChanged?

*Using Telerik controls here..

I am having problems trying to get a radAsyncUpload control to show up in a row of a radGrid when the row is selected by clicking anyplace on that row.  I am guessing I need to toggle the radGrid into Edit mode once a row is selected?  I have the radAsyncUpload control in the EditItemTemplate of the radGrid for the "Upload" column.  I would then like for the single upload be performed before any other row may be selected to upload another file.

RadPageView4 is the section in question.
