void gridView_RowDataBound(object sender, GridViewRowEventArgs e)

                    string ID = DataBinder.Eval(e.Row.DataItem, "ID").ToString();
                    Label lbl = (Label)e.Row.FindControl("lblFieldName");
                    RadToolTipManager1.TargetControls.Add(lbl.ClientID, ID, true);

        }

This is my first column in Grid.
So when I hover mouse on the first column. ToolTip is appearing.
But only problem is that, When I hove mouse first time on column,
ToolTip appear on Left Bottom position relative to page and not with grid column.

But next time it will appear at correct position. i.e. On First Grid Column.
This is my code, how I added RadToolTipManager in web part

                RadToolTipManager1 = new RadToolTipManager();
                RadToolTipManager1.AjaxUpdate += new ToolTipUpdateEventHandler(RadToolTipManager1_AjaxUpdate);
                RadToolTipManager1.RelativeTo = ToolTipRelativeDisplay.Mouse;
                RadToolTipManager1.Position = ToolTipPosition.BottomRight;               
                RadToolTipManager1.HideEvent = ToolTipHideEvent.ManualClose;
                this.panel.Controls.Add(RadToolTipManager1);

Please reply,
Thanks

I have a template column that performs odd when selecting and hovering the row:

When hovering (and selecting), the column shows a solid bottom line (see pic1).

Moreover, the hover style only works for the other columns and on certain parts in the template column.

This is how the code in the template column looks like:

<telerik:GridTemplateColumn HeaderText="Document" UniqueName="TemplateColumn"

DataField="DocumentName" Aggregate="Count" FooterText="Number of documents found: "

SortExpression="DocumentName" ItemStyle-Wrap="false">

<ItemTemplate>

<table style="width:100%;">

<tr>

<td nowrap="nowrap">

<asp:Image ID="Image1" runat="server" AlternateText='<%# Eval("ClassName") %>'

ImageUrl='<%# Eval("TypeIconUrl") %>' ToolTip='<%# Eval("ClassName") %>' />

<asp:Image ID="Image2" runat="server" AlternateText='<%# Eval("StateText") %>'

ImageUrl='<%# Eval("StateIconUrl") %>' ToolTip='<%# Eval("StateText") %>' />

<asp:Label ID="Label1" runat="server" Text='<%# Eval("DocumentName") %>'></asp:Label>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:GridTemplateColumn>

 
Any ideas how to solve this ?
