Extra space being put in table cell

For some reason thi开发者_如何学运维s code:

<td id="ddlHolidayCity" colspan="3">
                    <% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)
                        {%>
                            <%=i > 0 ? "," : ""%>
                            <%=DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text%>
                        <%}
                    %>
                    </td>

Is displaying cities like this:

New York , London

-- see the extra space before the comma? Where is that coming from???

It's probably coming from a newline or some other whitespace character just before escaping HTML to evaluate i. Since it's inside the for loop, it gets added to output. Try what happens if the spaces between angled brackets are removed:

<td id="ddlHolidayCity" colspan="3">
                    <% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)
                        {%><%=i > 0 ? "," : ""%>
                            <%=DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text%>
                        <%}
                    %>
                    </td>

To test this change the code to one line. Remove all spacing between your %> <% I bet it will fix it. See all the spacing below when I placed your code in a single line. Coldfusion had a directive to tell the renderer how to interpret code page white space.

<td id="ddlHolidayCity" colspan="3">                     <% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)                         {%>                             <%=i > 0 ? "," : ""%>                             <%=DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text%>                         <%}                     %>                     </td>
