Hi mehr_83,

i want this code only onec in per page.

If Not IsPostBack = False Then means only when the page refresh, below code will be fired. It's not clear what you want exactly, maybe you could provide more code including all you related front code and back code, especially the linkbutton click event code and SP code if it's necessary. Then a detailed description about the current issue and what you want to achieve.

Best Regard,

Yang Shen
