Multiple RadToolTipManagers for RadGrid

[Jay]

I have a RadGrid with two GridTemplateColumns.
i need to tooltipsify the GridTemplateColumns, so i have taken two RadTooltipManager controls on the page

i have written the following code in Grids ItemDataBound event. (Here btnbooking and btnReference are button controls in first  and second Gridtemplatecolumn ) OnAjaxUpdate methods for RadToolTipManager's are OnAjaxUpdateBooking and OnAjaxUpdateReference.
in these methods i am loading Booking.ascx and Reference.ascx usercontrols.

these two usercontrols contains "Close" button, on click of these buttons i need to hide the Tooltip. 

 when i click the close button i am getting the following error.
Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive:

please find the code in ItemDataBound event, OnAjaxUpdate and Javascript method for hiding tooltip

-- ItemDataBound Event
ToolTipManager1.TargetControls.Add(btnbooking.ClientID, btnbooking.Text, true);

ToolTipManager2.TargetControls.Add(btnReference.ClientID, btnReference.Text, true);

 

 -- OnAjaxUpdate methods

protected void OnAjaxUpdateBooking(object sender, ToolTipUpdateEventArgs args)

        {

            Control ctrl = Page.LoadControl("~/ControlLibrary/Booking.ascx");

            args.UpdatePanel.ContentTemplateContainer.Controls.Add(ctrl);           

            AppWeb.ControlLibrary.BookingDetails booking = (AppWeb.ControlLibrary.BookingDetails)ctrl;

 

            WTButton btnClose = (WTButton)ctrl.FindControl("btnclose");

            if (btnClose != null)

                btnClose.OnClientClicked = "CloseTooltipManager";

        }

 

        protected void OnAjaxUpdateReference(object sender, ToolTipUpdateEventArgs args)

        {

            Control ctrl = Page.LoadControl("~/ControlLibrary/Reference.ascx");

            args.UpdatePanel.ContentTemplateContainer.Controls.Add(ctrl);           

            AppWeb.ControlLibrary.DualDetails dual = (AppWeb.ControlLibrary.DualDetails)ctrl;

            dual.PageType = ApptType.EXPORT_DROPOFF;

            dual.lGateApptAssoc_Id = Convert.ToInt64(args.Value);           

             

            WTButton btnClose = (WTButton)ctrl.FindControl("btnclose");

            if (btnClose != null)

                btnClose.OnClientClicked = "CloseTooltipManager";                       

        }

 

-- Javascript method

function CloseTooltipManager(sender, args) {

             

 

            var controller = Telerik.Web.UI.RadToolTipController.getInstance();

            var tooltip = controller.get_activeToolTip();

 

            if (tooltip) {

                tooltip.hide();

            }

        }

please anyone help me where i am doing wrong.

I'm not sure if you've seen this thread, but it might provide a solution for your issue:

 Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive: Rebind.

Hope this helps.

Hi Shinu,

i resolved this issue by changing the ID of button in Booking.ascx from btnClose.

if i use "btnClose" for both the buttons in usercontrols i am getting the error.

thanks for you reply.

Thank you once again.

Regards,
Jai
