Hi I need to create a multicolumn menu similar in design to the demo(https://www.telerik.com/demos/aspnet/prometheus/Menu/Examples/MultiColumnMenu/DefaultCS.aspx)

I need to populate the values dynamically though. I have been playing with it for awhile now and really came up with what seems like a hack. It almost works, I still have a lot to clean up and figure out. Before I waste a lot of time doing that… This is what I did so far. I have to create a class based on itemplate then build the template and add it to the radmenu control collection. Is this the right way to do it? Do you have examples of how to create the multi column menu dynamically (from a database). I couldn’t find anything.

This is what I have..

HTML:

<telerik:RadMenu ID="MainMenu" runat="server" Skin="Web20" CssClass="qsfexMenu">

<Items>

<telerik:RadMenuItem Text="TopMenuItem">

<Items>

<telerik:RadMenuItem CssClass="ProductsSection">

<ItemTemplate>

<div class="qsfexCustomMenuSection">

<a class="alink" style="color:Blue;" href="" id="SubMenuItemCol1" runat="server" >ddd</a>

</div>

</ItemTemplate>

</telerik:RadMenuItem>

</Items>

</telerik:RadMenuItem>

</Items>

</telerik:RadMenu>

Code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

     If Not Page.IsPostBack Then

           SetupMenu()

      End If

End Sub

Sub SetupMenu()

 ' get menu items

Dim items As MenuItems = New MenuItems("989", "/M/C/MainMenu.ascx", DateTime.Today, "154")

For Each mItem As MenuItem In items

Dim item As RadMenuItem

      item = New RadMenuItem

      item.Text = mItem.MenuText

      item.NavigateUrl = mItem.MenuUrl

      If mItem.HasSubMenus Then

            LoadChildMenus(item, mItem)

      End If

      MainMenu.Items.Add(item)

Next

End Sub

Sub LoadChildMenus(ByVal item As RadMenuItem, ByVal mItem As MenuItem)

 If Not item Is Nothing Then

   For Each m As MenuItem In mItem.SubMenuItems

           Dim mct As MultiColumnTemplate = New MultiColumnTemplate()

            mct.text = m.MenuText

            mct.url = m.MenuUrl

            Dim x As RadMenuItem = New RadMenuItem(m.MenuText, m.MenuUrl)

            x.ItemTemplate = mct

            x.CssClass = "ProductsSection"

            item.Items.Add(x)

      Next

      End If

End Sub

Class MultiColumnTemplate

      Implements ITemplate

      Public text As String

      Public url As String

      Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn

      Dim menuText As String = text

      Dim menuUrl As String = url

      Dim a As HtmlAnchor = New HtmlAnchor()

      a.InnerHtml = menuText

      a.HRef = menuUrl

      container.Controls.Add(a)

End Sub

End Class

Thanks for your help. 

telerik:RadPanelBar runat="server" ID="RadPanelBar1" Width="400px" Height="280px" ExpandMode="FullExpandedItem">

    <Items>

        <telerik:RadPanelItem Text="XXX">

            <Items>

                <telerik:RadPanelItem>

                    <ItemTemplate>

                        (...)
                    </ItemTemplate>

                </telerik:RadPanelItem>

            </Items>

        </telerik:RadPanelItem>

    <telerik:RadPanelItem Text="Here a RadGrid">

        <Items>

            <telerik:RadPanelItem>

                <ItemTemplate>

                    <telerik:RadGrid (...)  DataSourceID="SqlDataSource1">
                        <MasterTableView DataSourceID="SqlDataSource1" >

                            <Columns>

                                (...)
                            </Columns>

                        </MasterTableView>

                    </telerik:RadGrid>
                    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="MyConnectionString"  SelectCommand="MySQLRequest"></asp:SqlDataSource>

                </ItemTemplate>

            </telerik:RadPanelItem>

        </Items>

    </telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

IT WORKS !

But now I want to set my connectionString and my SelectCommand in my code behind..
I remove them from the aspx page and add them into the aspx.vb page
but... when I write SqlDataSource1.ConnectionString ="MyConnectionString" or SqlDataSource1.SelectCommand ="MySQLRequest",
Visual Studio say me SqlDataSource1 is not declared ! But I haven't remove it in the aspx page !
What happend ? How can I resolve this problem ? Please let a little code snippet, if is exists !
Thanks in advance !

For redirecting we are using the javascript redirect: window.location.href ="NewPage.aspx".

The issue here is the page gets redirected first and is not waiting for the OK button click on the Radalert.
When we use normal alert the page is actually waiting for the user to click the OK button and then the new page is getting loaded

Any help on this greatly appreciated
Thanks and Regards
