Scrollbar ???

I have a form with different fields from my access table and I want to use a scrollbar to navigate the table.
How do I bind the dataset to the scrollbar?
Also, what are the events when clicking the scrollbar?

Thanks in advance,

There are no data binding events for a scrollbar.

Your best bet is to load the data into a Dataset first so you can access it dynamically and move both forward and backward.  A datareader wont help you in this situation.

Once you have the dataset, you can setup the properties for your scrollbar.  Set your minimum value to zero which will correspond to record zero.  Set the max value to Dataset.Tables(0).Rows.Count - 1.  This will insure that a user can't scroll past the maximum number of records in the dataset.

Respond to the following event and access your dataset.  The NewValue parameter will correspond with the row index that you want to access.

    Private Sub VScrollBar1_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles VScrollBar1.Scroll
        Dim Row as Datarow
        Row = MyDataset.Tables(0).Rows(e.NewValue)
        'Set your control values here
        Textbox1.Text = Row.Item("FirstName")
    End Sub

You could take some much more complex approaches if you truly wanted to create a DataBinder for a scrollbar, but I'm not sure if you really want to go through that trouble.

I don't think using scroll bar is a good approach in this case. You may use the database navigation technique as shown in the following links:

Ok, this should help.  This simple form binds 2 controls to a dataset that was generated with code.  The scrollbar navigates the records.
