The clientID of the Link Button added in to Target controller of tooltip manager. When mouse moves over the Link Button, the Ajax updating is happening. The Ajax updating event is comming.The problem is this postbacking is never ends. The code inside the update event is given below:

true);
protected void radToolMngr_AjaxUpdate(object sender, ToolTipUpdateEventArgs e)
{
Label lblInsideToolTip = new Label();
lblInsideToolTip.Text =
"This is Tool tip";
e.UpdatePanel.ContentTemplateContainer.Controls.Add(lblInsideToolTip);
}

Hi Anoop,
Would you please explain what exactly do you mean by "The Ajax updating event is comming.The problem is this postbacking is never ends"? The only similar problem I can think of without having further information is that after you have shown the first tooltip, when you perform a postback from a control which is even outside the tooltip, the OnAjaxUpdate event gets fired. If this is the problem you describe, we are aware of it and we are researching for a way to fix it because it is pretty complex one - the event should be fired when a postback is initiated by a control inside the tooltip in order to recreate the tooltip again and it is hard to determine whether the postback was initiated through a control inside the tooltip or not.
If this is not the problem you describe, please provide more detailed explanations or best - open a new support ticket and send us a sample, fully runnable demo along with detailed reproduction instructions and explanations of the actual and the desired behavior.

Hello,
"the event should be fired when a postback is initiated by a control inside the tooltip in order to recreate the tooltip again"
(the event=OnAjaxUpdate)
I stumbled on this thread while trying to figure out why it was firing when I click a control inside the tooltip: so OnAjaxUpdate fires when you first load the TT, and then when you perform a small postback inside the TT..?
Is there a way to avoid that OnAjaxUpdate event when clicking a postback control inside the TT?
(using tooltipmanager and a ton of targetcontrols for it, opens a tiny (4 html anchors, 2 Properties) user control... Getting some serious performance problems..)
Best regards,
Nicolai

Hello Nicolai,
When you click a postback control in the tooltip, you perform an ajax request. Since you dynamically load and add the user control in the tooltip, this means that if you do not go through the OnAjaxUpdate event, your tooltip will open blank without content. You can test this on your side in order to confirm that this is how the Framework works with dynamic controls - they should be recreated after a postback/ajax request.
