DataList - ItemDatabound and TooltipManager

[jc mag]

I've the following DataList:

<asp:DataList ID="dataListPhoto" runat="server" RepeatColumns="7" RepeatDirection="Horizontal" OnItemDataBound="dataListPhoto_ItemDataBound">
                <ItemTemplate>
                    <asp:Image ID="imgButton" runat="server" ImageUrl='<%# Eval("ImageUrl") %>' Width="32"
                        Height="32" userName='<%# Eval("User") %>' />
                </ItemTemplate>
            </asp:DataList>

And want to show a tooltip on each Image (imgButton):

<telerik:RadToolTipManager ID="ttm" Height="200px" Width="350px" HideEvent="LeaveTargetAndToolTip"
    RelativeTo="Element" Position="TopCenter" runat="server" Skin="Telerik" EnableShadow="true"
    Animation="Fade" ShowDelay="1000">
    <WebServiceSettings Method="GetHoveringText" Path="LinkHoveringAuthor.asmx"  />
</telerik:RadToolTipManager>

In my code-behind I try to add each Images to RadToolTipManager's TargetCollections:

protected void dataListPhoto_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        Image c = (Image) e.Item.FindControl("imgButton");
        string value = c.Attributes["userName"];
        ttm.TargetControls.Add(c.UniqueID, value, false);
    }

But the Tooltip is only displayed for the first Image....

2nd question: in my LinkHoveringAuthor.GetHoveringText method I try retrieve the userName:

var contextDictionary = (IDictionary<string, object>)context;

            if (contextDictionary["Value"] != null)

            {

                string name = contextDictionary["Value"].ToString();
...

It works, but backslashes are omitted... :-|
For example, here:

ttm.TargetControls.Add(c.UniqueID, value, false);

if value="dom\user", in the webmethod, the "name" variable equals to "domuser"...

Hi jc mag,

 Straight to your questions:

1) I was not able to reproduce the issue with the first item tooltipified only - please examine the attached demo which I prepared for you.

2) The "\" sign is a special sign and thus it would break the functionality once the content is returned - that is why the RadToolTipManager encodes it. However, you can manipulate the string e.g by replacing special signs with allowed signs when needed and vice versa - this is a standard asp.net approach e,g when dealing with databases.

For your convenience and reference I also demonstrated 2) in my demo, please use it as a start point and let me know how it goes.


Best wishes,

Thanks, all works now :)
(for the 1st problem, I had a RadAjaxPanel encapsulating the whole page, except the RadTooltipManager, so I think its TargetControls was not updated on ajax requests)
