Question

I have been having some trouble loading the CheckBoxList with data. I have been getting some errors on the DisplayMember and ValueMember.

Here is my cod:.

Protected Sub LoadCBMembers(ByVal objDeptGUID As String)
    Try
        Dim myCBTable As New DataTable()
        With myCBTable.Columns
            .Add("DisplayName", GetType(String))
            .Add("TextValue", GetType(String))   '<<<< change the type of this column to what you actually need instead of integer.
        End With
        Dim lqMembers As New lqFireFighterConnectDataContext
        Dim GetMembers = From r In lqMembers.tbUsers
                         Where r.DeptGUID = objDeptGUID And r.TextFLag = True
                         Select r
        If GetMembers.Count = 0 Then
            Exit Sub
        End If
        For Each foundMember In GetMembers
            myCBTable.Rows.Add(foundMember.FirstName & " " & foundMember.LastName, foundMember.CellPhone & "@" & foundMember.PhoneCarriers)
            '  cbMembers.Items.Add(foundMember.FirstName & " " & foundMember.LastName)
        Next
        With cbMembers
            .DataSource = myCBTable
            .DisplayMember = "DisplayName"
            .ValueMember = "TextValue"
        End With

    Catch ex As Exception

    End Try
End Sub

Answer 1

Try this:

    With cbMembers
        .DataSource = myCBTable
        .DisplayMember = "DisplayName"
        .ValueMember = "TextValue"
        .DataBind()
    End With

According to the documentation, this method must be called explicitly. Not all controls require you to call DataBind() explicitly (for many it is called for you implicitly), but CheckBoxList is an exception.
