Lets see the code. Is there elements in the collection or is it empty?

The error is pretty clear, isn't it? What is your question?

It is obvious that your DataView has no rows in it. You try to access the first row (index 0) but as none exists you get a 'index-out-of-range' error...
If you would expect data you should check why it didn't came...
In any case you should add a check to your code to see if there are any rows before you try to access one (any) of them...

C#

if(DataView.Count > 0)
{
  DataView.Item[0]...
}
