Any one can help me...
I have a checkbox and a checkboxlist in a datalist. I want the items in the checkboxlist should be checked or unchecked using checkbox control.
Datalist is binded to database table using objectdatasource.

This is one way to do it. Maybe not the cleanest but it works. There is a way to do it in the itemDatabound
1. Make a function to create the checkboxes.

2. Make a function to check or uncheck the check boxes like the example below which refers to the check box list created in the first function - cblEmpIDView.

    Function getWhatever()
        Dim SQL As String = "SELECT statement to find out which check boxes should be checked.";"
        Dim oDA As New SqlDataAdapter(SQL, _oConn)
        Dim oDS As New DataSet
        oDA.Fill(oDS)
        For Each i As DataRow In oDS.Tables(0).Rows
        Dim n As ListItem = cblEmpIDView.Items.FindByValue(i("EmpID"))
            If Not n Is Nothing Then
                n.Selected = True
            End If
        Next
    End Function
