RadComboBox Checkbox problem

[S L]

Why there was any error saying "CheckedItems is not a member of Telerik.WebControls.RadComboBox" ?
Why there was an error saying "Checked is not a member of Telerik.WebControls.RadComboBoxItem" ?

            Dim collection As IList(Of RadComboBoxItem) = rcb.CheckedItems
            Dim intCheck As Integer = collection.Count

            For Each itm As RadComboBoxItem In collection
                If itm.Value = drName(strColumn) And Not (drName(strColumn) Is DBNull.Value) Then
                    itm.Checked = True
                    Exit For
                End If
            Next

my development tools were VS2010 using IIS 6.5 ASP 2.0

Hi S L,

Unfortunately I couldn't replicate the issue at my end. Please have a look into sample code to which works as expected.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" CheckBoxes="true" runat="server">
    <Items>
        <telerik:RadComboBoxItem Text="Item1" runat="server" Value="1" />
        <telerik:RadComboBoxItem Text="Item2" runat="server" Value="1" />
        <telerik:RadComboBoxItem Text="Item3" runat="server" Value="1" />
        <telerik:RadComboBoxItem Text="Item4" runat="server" Value="1" />
        <telerik:RadComboBoxItem Text="Item5" runat="server" Value="2" />
        <telerik:RadComboBoxItem Text="Item6" runat="server" Value="2" />
        <telerik:RadComboBoxItem Text="Item7" runat="server" Value="2" />
        <telerik:RadComboBoxItem Text="Item8" runat="server" Value="2" />
    </Items>
</telerik:RadComboBox>
<telerik:RadButton ID="RadButton1" runat="server" Text="Get CheckedItems" OnClick="RadButton1_Click">
</telerik:RadButton>

C#:

Protected Sub RadButton1_Click(sender As Object, e As EventArgs)
    Dim collection As IList(Of RadComboBoxItem) = RadComboBox1.CheckedItems
    Dim intCheck As Integer = collection.Count
    For Each itm As RadComboBoxItem In collection
        If itm.Value = "1" Then
            itm.Checked = True
        Else
            itm.Checked = False
        End If
    Next
End Sub

Thanks,

Hi S L,

RadComboBox introduces CheckBox support in Q2,2011 version. Please upgrade your telerik version to solve the issue.

Thanks,
