CSS position a button inside gridview cell (ASP.NET)

Question

I've been struggling to position the edit button inside a gridview cell in the top right corner of the cell. The row height varies from row to row so I cannot use CSS height and the inside div does not fill the whole height of the row. Basically I want all the divs inside the template field (td) be the same height as the whole table row (tr). I attached two pics of what I get and what I want. Can someone help?

<asp:TemplateField HeaderText="Префикс GS1" SortExpression="gs1prefix">
    <ItemTemplate>
        <div style="width:110px;">
            <div style="top:0;right:0">
                <div style="font-size:0.6em;">
                    <asp:LinkButton runat="server" ID="lnkEdit2" CommandName="Edit" Text="(Изменить)" />
                </div>
            </div>
           <asp:Label runat="server" Font-Bold="true" ID="lblPartnersGs1Prefix" Text='<%# Eval("gs1prefix") %>' />
       </div>
    </ItemTemplate>
</asp:TemplateField

UPDATE: Here's generated HTML:

<td align="center" valign="middle">
    <div style="width:110px;">
        <div style="top:0;right:0">
            <div style="font-size:0.6em;">
                <a id="ContentPlaceHolder1_gvPartners_lnkEdit2_0" href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$gvPartners$ctl02$lnkEdit2','')">(Изменить)</a>
            </div>
        </div>
        <span id="ContentPlaceHolder1_gvPartners_lblPartnersGs1Prefix_0" style="font-weight:bold;">501028410</span>
    </div>
</td>

And the stylesheet fragment:

.ColoredGridView{
    background-color:white;
}

.ColoredGridView td {
    background-color: #9deef1;
    border-style: none;
    border-width: 0;
    padding: 8px;
}

.ColoredGridView td a
{
    border-bottom: 1px dotted;
    text-decoration-line:none;
}

There are two ways that you could tackle this

<asp:LinkButton runat="server" cssClass="myClass" ID="lnkEdit2" CommandName="Edit" Text="(Изменить)" />

and in your CSS create a class and then position it how you need

or

<asp:LinkButton runat="server" style="text-align: right; vertical-align: top;" ID="lnkEdit2" CommandName="Edit" Text="(Изменить)" />
