C# code behind *note if i comment the below line than i dont get js error.*

 if (btnDelete != null)
 {   
   btnDelete.Attributes["onclick"] = String.Format("return DeleteRow('{0}', '{1}', '{2}', '{3}');", e.Row.ClientID, e.Row.RowIndex, DataBinder.Eval(e.Row.DataItem, "Id"), DataBinder.Eval(e.Row.DataItem, "Name"));
}

//javascript
function DeleteRow(rowId, rowIdx, Id, Name) {    
    var result = confirm('Are you sure you want to delete this record? \n\n Id: ' + Id + "\n Name: " + Name);

It's hard to tell from your question, but it sounds like the values that are being returned are including the single quote character (apostrophe) which would end your string in the resulting javascript.

What is the code that is being generated for the lines that are throwing the error?

When similar things have happened to me it resulted in something like:

return DeleteRow('1', '2', 'abscde', 'Mc'Adams');

Which would cause an error because of the value Mc'Adams. If that is the case then you'll have to send your data through a method that escapes values that would otherwise corrupt your javascript.

You've used mixed single and double quotes. Change the line here;

var result = confirm('Are you sure you want to delete this record? \n\n Id: ' + Id + '\n Name: ' + Name)

btnDelete.Attributes["onclick"] = String.Format("return DeleteRow('{0}', '{1}', '{2}', '{3}');", e.Row.ClientID, e.Row.RowIndex, DataBinder.Eval(e.Row.DataItem, "Id"), DataBinder.Eval(e.Row.DataItem, "Name").ToString().Trim().Replace("'", "\\'")));
