radcombobox in a radgrid user control on a multipage, selectedindexchanged not triggering

[Philip]

I have an issue where I have a radcombobox on a web user control inside a radgrid. The radgrid is inside a radmultipage. I am using a radajaxpanel as well. I noticed that the selectedindexchanged event of the combobox is not triggering. Furthermore, once I move the radgrid outside of the multipage, it is working fine. Is this a bug? I do need to use a multipage so is there a way for me to get this to work? See code snippets below.

Thanks!

ASPX:

    <telerik:RadAjaxPanel ID="rpnlTest" runat="server" Width="100%">

                <telerik:RadTab Text="Step 2" PageViewID="rpvStep2" Value="Step2">
                </telerik:RadTab>

            </Tabs>

                                    </EditFormSettings>

ASCX source:

                </Items>
            </telerik:RadComboBox>

ASCX code:

    protected void rcbTypeBusActivity_SelectedIndexChanged1(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        pnlIndividual.Visible = false;
        pnlIndustry.Visible = false;
        pnlOther.Visible = false;
        if (e.Value == "Individual" || e.Value == "Business Entity")
            pnlIndividual.Visible = true;
        else if (e.Value == "Industry")
            pnlIndustry.Visible = true;
        else
            pnlOther.Visible = true;
    }

Hello Philip,

The provided markup looks correct to me, and there is nothing obvious that may cause the problematic behavior. therefore I would suggest you to open a regular support ticket and send us sample runnable application which demonstrates the problematic behavior. Thus  we will be able to debug it locally and advise you further.

Kind regards,
