I have added the following line of code to the admin/Containers/ActionButton.ascx.vb file "ModuleActionIcon.AlternateText = action.Title" and built the dll.
When I tried to run it, I noticed that my change had not been recognised and so I debugged into it where I saw that the code and the dll were out of sync. The dll had built into the Solutions/DotNetNuke.bin folder so I copied the dll into the source/bin folder. When I ran it again my change had been picked up and worked but I got a diff error saying "Multiple controls with the same ID 'ctr' were found. FindControl requires that controls have unique IDs.".
Can anyone point me in the right direction as to what you need to do get this working? I do not think it has anything to do with the alternatetext as it does work but must be the way dll or the way I'm building it?
The javascript is also throwing an error "Object doesn't support this property or method"
