Hi everyone. Maybe someone have the solution for my probleme. I have a gridview with different columns. One of them is for thye edit button which display a popup details view. Everything works fine the first time I click on the edit button. But if I click again on the same or another edit button, nothing happens. The debugger says nothing. All the variable seems to pass without issues. I don't know what to do to solve my issue. Is someone has a idea ? Thank in advance
