Extra space at the end of a Telerik RadGrid - asp.net

Question

I have a Telerik RadGrid on my aspx web page. I notice that when I run my web application I get an extra space at the end as the below picture illustrates. I'm not sure why this shows up, I checked the markup and there is no extra column, hidden or otherwise, after the last column with the Drop link. I also looked at the RadGrid properties and there's nothing there that seems to indicate that there's anything additional that is being rendered. That extra space does not show up in the visual designer, so I'm not sure what is causing it. Any help is appreciated.
Markup for the RadGrid is shown below:
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" OnItemCreated="RadGrid1_ItemCreated"
OnDeleteCommand="RadGrid1_DeleteCommand" GridLines="None" AllowSorting="True"
Skin="Web20" PageSize="20" FooterStyle-Wrap="false" >
<MasterTableView EditFormSettings-PopUpSettings-Modal="True" EditMode="PopUp" DataSourceID="SqlDataSource1"
AutoGenerateColumns="False" DataKeyNames="ID" ShowFooter="True" AllowPaging="True">

Answer 1

I usually run into this when a width value for each column that does not add up to the width value of the RadGrid or leaving width values out altogether..
Try entering width values for each column but leave out the width value for the one column that would usually be the longest. In this case, I would choose the Title column.

Answer 2

Got it, turns out I was setting the ColumnSpan to an arbitrary number, 2 in this case, in the code-behind where the RadGrid is generated and it was causing that additional space to appear at the end. I was doing this to test another issue that has since been resolved. The snippet of code that was causing this is as follows and is commented out in my code now.
footerItem.Cells(2).ColumnSpan = 2
