Hello,

I write an application with dynamically generated buttons that make changes to a database (DELETE, INSERT). A button calls a sub (Objednavka) that makes the change (AddHandler btnItem.Command, AddressOf Objednavka). The problem is that I detect the change made by the mentioned buttons inside Page_Load sub but the change sub runs after the Page_Load, not before it so the data on the page is incorrect (one step old). I can use a workaround and refresh the page after the change is made in the db but then I loose my scrool position on the web page which needs to be retained. :(

Any help appreciated,
Radoslav

Usually, anything that dynamically generates objects on the page based on some underlying data (typically utilizing databinding) is done based on events that affect that underlying data. You usually need to do this once when the page loads, but you also need to redo this when the data is changed.

I typically create a method that handles the retrieval of the data and the binding/drawing of the controls that are affected. I call this routine during the first page load (based on IsPostback), then again whenever I do something that affects the data.

Method: Page_load()
    If Not IsPostback Then
        'Call sub to build the dynamic controls
        buildMyDymanicControls()
    End If

Method: buildMyDymanicControls()
    'Get data from database
    'Manipulate controls thur databinding

Method: someButtonHandler()
    'Do things that affect the data
    'Call sub to rebuild the dynamic controls
    buildMyDymanicControls()
