[Solved] Adding a tooltip - not so easy?

[Clive Hoggar]

Hi guys

Thanks for all your help so far!

Following the help docs I have added this in code behind to add a very simple tooltip
to my grid which should show the record ID on mouseover.

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

        If (TypeOf e.Item Is GridDataItem) Then
            Dim gridItem As GridDataItem = CType(e.Item, GridDataItem)

            For Each column As GridColumn In RadGrid1.MasterTableView.RenderColumns
                If (TypeOf column Is GridBoundColumn) Then

                    gridItem(column.UniqueName).ToolTip = ("ID: " + gridItem.OwnerTableView.DataKeyValues(gridItem.ItemIndex)("ID").ToString)

                End If
            Next
        End If
    End Sub

This doesn't actually do anything - no hand appears on mousover, no tooltip.

Do I also need RadAjax Manger and Tooltip manager in the declarations? The docs don't mention it but
the demo shows them so added this as my grid has paging and sorting  (I already have radajaxmanager in master page):

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
                    <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                        <telerik:AjaxUpdatedControl ControlID="RadToolTipManager1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
                    </telerik:RadAjaxManagerProxy>

                <telerik:RadToolTipManager ID="RadToolTipManager1" runat="server"
                        ManualClose="True">
                    </telerik:RadToolTipManager>

Still haven't succeeded.   Maybe some 'imports'missing in code behind? 

Can you suggest where I am going wrong?

Thanks

From what I can tell your code does "tooltipify" your grid, however that is all that it does. Basically you create the tooltips for grid items but you never try to show them. You also never interact with the tooltipmanager which is also important for actually maintaining and displaying your tooltips.

I say take another look at the demo that I assumed you based this off of. Hopefully looking into it more (the function you posted is similar in structure to the one in the demo, except you don't do anything with the tooltipmanager) will help you out!
