I have a RadToolTipManager with OnAjaxUpdate set. This Control sits inside a RadTabStrip with AutoPostBack='true' and MultiPage RenderSelectedPageOnly='true'. The TabStrip and MultiPage sit inside a RadAjaxPanel.
When EnableAjax='true' on the RadAjaxPanel the tooltips do not show. No error is shown it simply does not show. When I set EnableAjax='false' everything works as expected.
Is tehre corrently a work around for this?
Thanks in advance

I am using the exact code that you have provided with the versions of the controls you mention. However, I do not understand which element you expect to be tooltipified - the TargetControls collection is empty.
In order to speed up the process of finding the cause for this behavior, please open a new support ticket and send us your test project as an attachment together with detailed information on the expected behavior. We will have a look at the project right away.

public partial class Test : Page
{
protected void Page_Init(object sender, EventArgs e)
{
Label l1 = new Label();
l1.ID = "l1";
l1.Text = "Label 1";
Label l2 = new Label();
l2.ID = "l2";
l2.Text = "Label 2";
phTooltipeableControls.Controls.Add(l1);
phTooltipeableControls.Controls.Add(l2);
}
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack) { return; }
rttm.TargetControls.Add("l1");
rttm.TargetControls.Add("l2");
}
protected void DisplayTooltipForCell(object sender, ToolTipUpdateEventArgs args)
{
args.UpdatePanel.ContentTemplateContainer.Controls.Add(InfoLabel);
InfoLabel.Visible = true;
InfoLabel.Text = "Tooltip Test Text: " + args.TargetControlID;
}
}
I added the code-behind to my test page, however, I get the same behavior no matter the value of the EnableAjax property. The problem comes from the fact that you update the RadToolTipManager and do not add the IDs of the labels to its TargetControls when you postback the page. In case you move the code that adds the IDs to the method where you create/recreate the labels, everything works as expected:
| protected void Page_Init(object sender, EventArgs e) |
| { |
| Label l1 = new Label(); |
| l1.ID = "l1"; |
| l1.Text = "Label 1"; |
| Label l2 = new Label(); |
| l2.ID = "l2"; |
| l2.Text = "Label 2"; |
| phTooltipeableControls.Controls.Add(l1); |
| phTooltipeableControls.Controls.Add(l2); |
| rttm.TargetControls.Add("l1"); |
| rttm.TargetControls.Add("l2"); |
| } |
| protected void Page_Load(object sender, EventArgs e) |
| { |
| if (IsPostBack) { return; } |
| } |
