I have a RadUpload control in EditTemplate inside a RadGrid.
I add the client code to add addtional field with TextArea type allowing user to enter comment for the uploading file.
And that additional comment field is a required field, also only 500 characters max limited.
I want a TextArea type because I want to user to see all the text they enter and input type=text just won't do the justification.
I seem to have a problem to get the addional field's value at client side code. 

I use  
   var radGrid = $find('<%= rgGrid.ClientID %>');

to get the grid control
   var radUpload = $telerik.findControl(radGrid.get_element(), "rdProfile");
to get the upload control

When I try to retrive the value of the additional field by code similar to
   var descValue = $get(radUpload.getID() + 'Title' + i).value 
I am getting javascript error saying "object needed"

Anyone can help?
I attached my code

Hello Kevin,

Actually the correct client method to get the id is get_id(), not getID(), please replace it like this:

var descValue = $get(radUpload.get_id() + 'Title' + i).value
