hello,

please can someone help me out, i'm stuck with an error message when i tried to debug the code in chapter 7 - navigation.

the code is : 'ASP.masterpages_frontend_master' does not contain a definition for 'TreeView1_SelectedNodeChanged' and no extension method 'TreeView1_SelectedNodeChanged' accepting a first argument of type 'ASP.masterpages_frontend_master' could be found (are you missing a using directive or an assembly reference?)

i got stuck with this code when i tried to make the menu for the DarkGrey theme of the Planet Wrox website.

please, someone help me on how to go about solving this problem.

Hi there,

Sounds like you accidentally double-clicked the TreeView in Design View but then never saved the autogenerated method in the code behind.

Look at the code for the <asp:TreeView /> and then remove the attribute for OnSelectedNodeChanged.

Hope this helps. If it doesn't, please post your code.

Cheers,

Imar
