    In one of our application's page we have a repeater which displays results and contains controls such as hyperlinks which display certain contents in a tooltip.

    The content which is to be displayed in the tooltip is same for all the items of repeater and is in a user control. As its same, it doesnt really make sense to add multiple instances of this user control for each repeater item.

    I tried with Tooltip manager as well which can have multiple target controls but its more suited to on load demands, and content being the same i dont want to make a request to the server every time when user clicks for tooltip.

    What I am looking for is adding my tooltip content user control once in a page and then display it with multiple targets without calling server.

    I am just wondering what would be the best way to do it.

    Thanks in advance.

    Hello Khurram,

    You can indeed use one RadToolTipManager on your page to show the same tooltip for multiple items in a Repeater control. However, since the items displayed in a Repeater are created dynamically, you will need to use the Repeater's OnItemDataBound event to dynamically add those items to the RadToolTipManager's TargetControls collection.

    Here is a simple example:

    1 <telerik:RadToolTipManager ID="RadToolTipManager1" runat="server" 
    2     Text="Hello, RadToolTip!"
    3 </telerik:RadToolTipManager> 
    5 <asp:Repeater ID="Repeater1" runat="server" 
    6     OnItemDataBound="Repeater1_ItemDataBound"
    7     <ItemTemplate> 
    8         <asp:Label ID="Label1" runat="server"  
    9             Text='<%# Eval("Name") %>'/> 
    10         <br /> 
    11     </ItemTemplate> 
    12 </asp:Repeater> 

    1 protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) 
    3     if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item) 
    4     { 
    5         var label = e.Item.FindControl("Label1"as Label; 
    6         RadToolTipManager1.TargetControls.Add(label.ClientID, true); 
    7     } 

    This method adds the tooltip to every item in the Repeater, and you will not have to make any trips to the server for the tooltip to be displayed.

    I hope this was helpful. Please let me know if I can assist you further.
