Here is how I ended up solving the problem:
Note there is an extra space between the opening < and % and closing % and >

NavigateURL=' <%# "javascript:window.open(\"CustomerContactHistory.aspx?CID=" + DataBinder.Eval(Container, "DataItem.CustomerID") + " \", \"\", \"status=0,toolbar=0,menubar=0,location=0,directories=0,scrollbars=1.resizable=1\"); javascript:void(0);"%> '

>Fred,
>Here is a good link for window.open:
>http://www.devguru.com/Technologies/ecmascript/quickref/win_open.html
>
>If you add the following code to a htm file and try to run it in a browser it will display a window without a toolbar:
>

><form>
><input type=button value="Open new window"
>onClick="myRef = window.open(''+self.location,'mywin','left=20,top=20,width=500,height=500,toolbar=0,resizable=0');">
></form>
>

>Maybe try to remove menubar=0 from your example.

>>NavigateUrl="javascript:window.open([Open Angle Bracket Percent Sign]# 'CustomerContactHistory.aspx?CID=' + DataBinder.Eval(Container, 'DataItem.CustomerID') ,'_new','toolbar=0,menubar=0')[Percent Sign Close Angle Bracket] "
