I have a gridview in my page. grid has one linkbutton. how can set a color to a row of gridview when linkbutton is clicked?

```
<asp:TemplateField ItemStyle-Width="20%" HeaderText="Options" HeaderStyle-CssClass="headerfont">
                <ItemTemplate>
                    <div class="headerfontnew">

                        <asp:CheckBox ID="checkView" runat="server" Checked='<%# bool.Parse(Eval("rm_rights").ToString() == "1" ? "True": "False") %>' Enabled="true" onclick="CheckBoxCheck(this);"/>
                        <asp:CheckBox ID="checkInsert" runat="server" Checked='<%# bool.Parse(Eval("rm_rights").ToString() == "2" ? "True": "False") %>' Enabled="true" onclick="CheckBoxCheck(this);" />
                        <asp:CheckBox ID="checkUpdate" runat="server" Checked='<%# bool.Parse(Eval("rm_rights").ToString() == "3" ? "True": "False") %>' Enabled="true" onclick="CheckBoxCheck(this);"/>
                        <asp:CheckBox ID="checkDelete" runat="server" Checked='<%# bool.Parse(Eval("rm_rights").ToString() == "4" ? "True": "False") %>' Enabled="true" onclick="CheckBoxCheck(this);"/>
                     <asp:LinkButton ID="LinkButton1" CommandName="Child" CommandArgument='<%#Eval("menu_id")%>' runat="server" >

                        <img id="ChildMenu" src="images/image_viewer.png" class="Gridimage" title="View Childs" runat="server"   ></img></asp:LinkButton>

                    </div>
                </ItemTemplate>
                <HeaderStyle CssClass="headerfont"></HeaderStyle>
                <ItemStyle></ItemStyle>
            </asp:TemplateField>

```
