ASP.NET Checkbox List - How to read what was checked after submit

Hi Experts,

I have a dynamic checkbox list

<asp:CheckBoxList ID="CheckBoxList1" DataSource="<%# DataSet1.DefaultView %>" DataTextField="Description" DataValueField="ID" runat="server" RepeatDirection="Vertical" RepeatLayout="table"></asp:CheckBoxList>

Works great and displays correctly.

Once the user has checked the boxes they want, how do I read what was checked on the submitted page?

What I am trying to do is build a page that checks for available times in the database

Eg: The user may select Lesson1,Lesson2 and Lesson6
The resulting page will search the database for anything with those requirements and return a datagrid or repeater.

How do I know what boxes have been ticked so I can build my query.
Thanks a lot
Nik

VB Code [for multiple user selection]

the selections are stored in the variable s. You can retrieve the data giving the WHERE clause using this variable and it will accordingly retrieve the data.


 Dim s As String = "Selected items:"
        For Each item As ListItem In CheckBoxList1.Items
            If item.Selected Then
                ' list the selected item
                s += item.Text + "<br>"
            End If
        Next
