Apologies if this potential bug has already been isolated.

In Q1 2009 (version 2009.1 311 - March 11, 2009)...
RadToolTip Show() throughs a javascript error if Position is not set or set to values other than "Center".
The javascript error is 'window' is null or not an object.
The error occurs in Internet Explorer (IE) but not FireFox or Chrome.
I have not tested other browsers or all possible Position values.

The following simplified code demonstrates the behavior:

The following works (Position value is set)

<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" />
        <div>
            <telerik:RadToolTip ID="RadToolTip1" runat="server" HideEvent="ManualClose" Position="Center">
                <br /><hr />Tool Tip Message
            </telerik:RadToolTip>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
        </div>
    </form>
</body>

The following fails (Position value is not set)

<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" />
        <div>
            <telerik:RadToolTip ID="RadToolTip1" runat="server" HideEvent="ManualClose">
                <br /><hr />Tool Tip Message
            </telerik:RadToolTip>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
        </div>
    </form>
</body>

CodeBehind
using System;
public partial class TestToolTip : System.Web.UI.Page
{

    protected void Page_Load(object sender, EventArgs e)
    {
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
                    RadToolTip1.Show();
    }
}

Thank you for your prompt attention to this matter.

Hi ATX,

I assume what might be causeing this issue, would you please test whether including the following script fixes the issue:

    
                    <script type="text/javascript">  
        
                     Telerik.Web.UI.RadToolTip.prototype._oldAdjustCallout = Telerik.Web.UI.RadToolTip.prototype._adjustCallout;  
        
                   Telerik.Web.UI.RadToolTip.prototype._adjustCallout = function()  
        
                {  
        
                      if(!this.get_targetControl()) return;  
        
                      this._oldAdjustCallout();    
        
                };  
        
                    </script>
