    I am using RadTooltipmanager for a control in detailview section of a radgrid. Tooltipmanager is bound in item_databound event and associated with user control in Ajax update event. Tooltipmanager is properly invoked and page_load event of the user control is also fired but still user control is not loaded in the tooltipmanager.

    Code in item_databound event ->

        if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)
                            Control target = e.Item.FindControl("imgFinal");
                            if (!Object.Equals(target, null))
                                if (!Object.Equals(this.RadToolTipManager1, null))
                                    DataRowView currentRow = (DataRowView)e.Item.DataItem;
                                    //Add the button (target) id to the tooltip manager

                                    ToolTipTargetControl tltpCntrl = new ToolTipTargetControl(target.ClientID, ((Image)target).ImageUrl, true);
                                    catch (Exception ex)


    Ajax Update event 

     Control usrControl = Page.LoadControl("~/Common/Controls/EPScoring.ascx");

    Hello Subha,

    Please examine this help article that treats the most common issues related to this: Most notably, make sure that the user control has an ID; that there is no server error and that the tooltip manager itself is not part of the partial page rendering.
