which radtooltip to use

[Kevin]

So what I need to load is a simple list that pops-up when a use hovers over a label for education i want to show the education temr sfroma database.  Don't wnat to preload into label as that;s wasteful html.  What I would like is a service that hooks to the db and return the list each time someone hovers over the label.  I tried using the radtooltip but could find no way to hook up to a web service, I then found radtooltip manage but I cant find a way to hook this up to the label on the page.

<asp:Label ID="lblKey" runat="server" Text="Key" Font-Size="XX-Small" ForeColor="Blue" Font-Underline="true" style="cursor:pointer"></asp:Label>
                        <telerik:RadToolTipManager ID="radEdlvl" runat="server" Position="MiddleLeft" Animation="Fade" Width="100px" Height="200px" RelativeTo="Element" HideDelay="20" Text="Hello" >


service, dont know if this will work but cant even see if it works wil the label on page.

  <WebMethod()> _
    Public Function GetToolTip() As String
        sql = "Select strEducationCode + ' - ' + strEducation from Education order by strEducationCode"

        myDataTable = New DataTable
        myDataTable = getReader(sql)

        If myDataTable.Rows.Count > 0 Then
            GetToolTip = myDataTable.ToString
        Else
            GetToolTip = Nothing
        End If
        GetToolTip()
    End Function

Hi Kevin,

You can use the RadToolTip, in order to 'tooltipify' a single element and use the RadToolTipManager in scenarios where many elements would require a tooltip. More information on comparison between both controls is available in this help article and ToolTip - RadToolTip versus RadToolTipManager online demo that illustrates both approaches.

You can also find useful the following online demos that treats similar scenario like the mentioned one:

• ToolTip - Cache loaded data
• ToolTip - Load on Demand
• ToolTip - Web Service

as well as the following help articles:

• Using the TargetControls Collection
• Load Content On-Demand
