Query Regarding User Control State Maintanance

hi friends, I am having a query regarding User control state management.
My query is i have created a toolbar user control with dynamic images changing on-mouse over and out.Now on my toolbar i am having a delete link button for which i want a confirmation from the user with an alert message box whether to delete or cancel.My problem is when page1.aspx is loaded and when i click on the delete link button the page is being posted back and from the second click of the delete link button i am able to get the alert message box.Also on my toolbar control i am having an add,modify etc buttons,when clicked on any of the links (i mean to say that when we are redirected to another page where in all the aspx pages the toolbar control is a common one) on the new aspx page from which we are redirected to,here also(on the redirected page) i am facing the same problem( when i click on the delete link button the page is being posted back and from the second click of the delete link button i am able to get the alert message box).
My requirement is on any aspx page where i am having the toolbar on a single click i want the alert message dilogue box with delete and cancel options
Can any one help me out in this regard
