-Now the checkboxes work but the imagebutton click cannot(which work perfectly the previous time). Is this due the the page load code where both ispostback are place together? Both can work if only they are on different forms and only one can function in the particualar form. -one more problem:(checkbox) when i first view a particular page, everything was displayed as expected. however, when i make another selection (which is page ispostback), I'm able to view the data on the second button click. Which means when i first select and click on the button, no event was called but the breaskpoint did step into the method. Only upon 2nd selection and buttonClick, the data was then displayed. Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Put user code to initialize the page here If IsPostBack And CType(Session("Checkbox"), Boolean) Then-->checkbox createcheckbox() End If If Not Session("ButtonCreated") Is Nothing Then---> imagebutton buttoncreated = CType(Session("ButtonCreated"), Boolean) Else buttoncreated = False End If If IsPostBack And buttoncreated Then createCalendar() End If End sub Is this due to the code in the page load? These are the codes you gave me and i have edited some and implement it
Right... well... hmmm... The code I gave you was fairly generalized and not particularly optimized to a particular implementation. Therefore, it is difficult to characterize what you've shown here as "right" or "wrong". If anything, I'd refactor and simplify as much as possible:
Protected checkboxExists As Boolean
Protected buttonExists As BooleanPrivate Sub Page_Load(...) ...
If IsPostBack Then
Dim checkboxExists As Boolean = CType(Session("Checkbox"), Boolean)
Dim buttonExists As Boolean = CType(Session("ButtonCreated"), Boolean)
If checkboxExists Then
createCheckBox()
End If
If buttonExists Then
createCalendar()
End If
End If
Session("CheckBox") = checkboxExists
Session("ButtonCreated") = buttonExists
End SubThis is normally the point at which it becomes increasingly difficult to impart any significant advice, unless there is something specific that is terribly wrong; at this point, you have to {code, test, debug} as many times as it takes to get it right. What a piece of work is man, how noble in reason, how infinite in faculties, in form and moving how express and admirable . . . and yet to me, what is this quintessence of dust? -- Hamlet, Act II, Scene ii.

Well, this problem has been solved. However, the imagebutton still can't work!! It works before i add the mouseover tooltip. Stil wondering what went wrong. Can help? The codes in page_load is the same as above(what you gave) Createcalendar subroutin when i create the imagebutton: Dim img As New ImageButton AddHandler img.Click, AddressOf ImageClickHandler img.ImageUrl = Server.MapPath("Pics\pencil.gif") cellleft.Controls.Add(img) row.Controls.Add(cellleft) buttoncreated = True Session("ButtonCreated") = buttoncreated what went wrong? :sigh:

One imagebutton is created when the date is >=date.today and also depends on the number of records in the database. So it hard for me to estimate the number imagebutton controls i wil be creating. It will check against the date and number of records in database. How many time the method is called depends on the number of rows.

There must be something that links them together right? If not how come with the same code and just he change of checkbox codes, everything can't work??? Im going crazy soon.. Have been trying several ways..
Well, yes... I'm not certain which snippet you're referring to, but in general, bear in mind that you're writing code that responds to particular events and each control event is independent of others on the same page, except for the page level events, that fire each time the page loads or posts. So, if, for example, I write an event handler for a button that creates a checkbox dynamically and stores some indication of that in Session, and later on I write an event handler that responds to the click event of another control that also dynamically creates something, I have to store some other indicator of that in Session as well, and so on, for each thing that I do. Do you see? If need be, I can point to the places in MSDN that describe the sequence of events and ASP session or state management.

Now I can leave out the dynamic checkboxes. Will be using checkboxlist instead (which can wotk with the dynamic imagebutton the previous time), so i guess this wouldn't be much of a problem as compare to the dynamic checkbox, am i right? However, I got to run the weekly form before i can click the button of the daily?
Page load If Not Session("ButtonCreated") Is Nothing Then buttoncreated = CType(Session("ButtonCreated"), Boolean) Else buttoncreated = False End If If IsPostBack And buttoncreated Then createCalendar() End If private sub createcalendar() imgholi.ID = rid imgholi.ImageUrl = Server.MapPath("Pics\pencil.gif") AddHandler imgholi.Click, AddressOf ImageClickHandler cellleft.Controls.Add(imgholi) buttoncreated = True Session("ButtonCreated") = buttoncreatedi have 3 calendars(Daily, weekly, monthly). If i were to select the daily calendar and click on the imagebtn, the table refreshes unless i select the weekly calendar and click the imgbtn. why? -

BIG BIG PROBLEM! Any idea what error is this? An error has occurred because a control with auto-generated id '_ctl4' could not be located to raise a postback event. To avoid this error, explicitly set the ID property of controls that raise postback events. When the page is loaded the first time, everything is fine. However, when i click next, to show other day of the event calendar, It create TWO calendars instead of 1. Why is this so?

What is the cause for this error? I have assigned a unique ID to each controls. An error has occurred because a control with auto-generated id '_ctl26' could not be located to raise a postback event. To avoid this error, explicitly set the ID property of controls that raise postback events. How i can get the value of which iamgebutton is click. i need to pass the value to another form when click.
