c# - HyperLink field in Gridview (Url Navigation) -

at work there gridview , has following syntax

  <asp:hyperlinkfield      datanavigateurlfields="nameid"      datanavigateurlformatstring="names.aspx?nameid={0}"     datatextfield="name"      headertext="client name"      sortexpression="name"      itemstyle-width="100px"     itemstyle-wrap="true" /> 

so added line datanavigateurlformatstring... link showing address looks this

http://.....clients/clientnames/names.aspx?nameid=123 

this gridview in clientsnames folder.. want use names.aspx of maintenance folder... want url redirect this

httpl//....clients/maintenance/names.aspx?nameid=123 

i tried add datanavigateurlformatstring="maintenance/names.aspx?nameid={0}" instead create url this

http://......clients/clientnames/mainteanance/names.aspx?nameid=123 

how can make url looks grid view?

http://.....clients/maintenance/names.aspx?nameid=123
