Hello Dayana Maliyakal,

It is not clear from the post why do you have such issues.
What do you mean when you say that sometimes works and sometimes it doesn't?
Is there any scenario that reproduces the issue?

Regarding the way you are keeping the history, did you implement any OnNavigateHistory
handler so that you can reload the previous state successfully?
For more information, you can read the following article from Microsoft:
Managing Browser History

Hope this helps.

Hi Telerik Team,
   Thank you for your reply.Actually we have an aspx page with one usercontrol with a RadTreeView and the rest of the contents is in the page itself.
On clicking each node of RadTreeView corresponding contents will be displayed on the right side of the page itself.Please see the attached files.
In that case we got  the back button as enabled and getting the browsing history for some nodes only.ie.sometimes back button is enabled and got the browsing history for the node test1.But on next time loading the page it may be disabled.Each time this back button issue is on different node.
Please give me reply

Hello Dayana Maliyakal,

I could not see any attachments.
But as I told you before, you should write some code in order to make the back button work.
This gets explained in the Microsoft link that I provided.

Another detailed example could be found here:

Hello Dayana Maliyakal,

In this example they are using just one method to handle all of the onclick events of the buttons.
You can change the OnClick attribute of each button in the declaration to point to a different method than the previous.
I.e:
And then in the code behind you would have:

I am also attaching a sample.

Hope this helps.

Hello Dayana Maliyakal,

Can you provide some example code that illustrates such issue?

Hi Telerik Team,

   The following code we are using and it has history problem with IE8

  string ToolTipFormater = "<table cellspacing=\"0\" cellpadding=\"0\" border=\"0\" style=\"width: 200px;\">"
                + "<tr><td class=\"NormalBold\" style=\"white-space:pre-line;background-color: #a8c1e4;border-bottom:1px solid #A5B3C5;\">{0}</td></tr>"
                + "<tr><td style=\"white-space:pre-line;\">{1}</td></tr></table>";


    rtNode.Attributes.Add("onMouseOver", "showToolTip(this,'" + Title + "','" + string.Format(ToolTipFormater, Title.Replace("\r", "<BR>").Replace("\n", "<BR>").Replace("'", "`"), Description.Replace("\r", "<BR>").Replace("\n", "<BR>").Replace("'", "`")) + "')");
         


rtnode----->radtreenode
Title,Description  are string values 


function showToolTip(element, Content1, Content2) {
        var tooltipManager = $find("<%= RadToolTipManager1.ClientID %>");


        //If the user hovers the image before the page has loaded, there is no manager created
        if (!tooltipManager) return;


        //Find the tooltip for this element if it has been created 
        var tooltip = tooltipManager.getToolTipByElement(element);
        //alert(Content);
        //Create a tooltip if no tooltip exists for such element 
        if (!tooltip) {
            tooltip = tooltipManager.createToolTip(element);
            //tooltip.set_title(Content1);
            tooltip.set_text(Content2);

        }

        //Let the tooltip's own show mechanism take over from here - execute the onmouseover just once
        //element.onmouseover = null;
        //show the tooltip
        tooltip.show();
    } 

Hello Dayana Maliyakal,

Note that when you use the ToolTipManager control inside an UpdatePanel, you have to make sure that the outer UpdatePanel UpdateMode is set to Conditional. The reason for this is that the RadToolTipManager has its own UpdatePanel integrated.

Now, judging by the sample code that you provided, I see no code that implements some HistoryPoint, so that the tooltip shows the correct data when you click the back button.

I am attaching a solution that illustrates how you can achieve what you are trying to do.
Some points to notice:
-I am defining the  RadToolTipManager outside the UpdatePanel1, for the above-mentioned reason.
-Whenever the mouse is over a tree node, the RadToolTipmanager1_AjaxUpdate would fire and would set an history point.
-Then the tricky part comes when you hit the back button. In this case the OnNavigate method gets fired and in there you have to fire the Update method of the RadToolTipManager1 as its mode is set to Conditional.
