Edit and update gridview rows on mouse click event

Question

I want to edit and update gridview rows on mouse click event. If the user clicks on a row it should become editable and when he again clicks on the same row it should become uneditable and the changes should be saved.

my gridview looks like:-

<asp:GridView ID="grdexcelsheet" runat="server" AllowPaging="True" 
                AutoGenerateColumns="False" RowStyle-HorizontalAlign="Left" HorizontalAlign="Center"
                onpageindexchanging="grdexcelsheet_PageIndexChanging" 
                Width = "100%" Height = "100%" Font-Size="Small">
                <PagerSettings Position="Bottom" Mode="NextPreviousFirstLast"  FirstPageText="First" 
                     LastPageText="Last"  NextPageText="Next" PreviousPageText="Prev" PageButtonCount="5" />
                <Columns>
                <asp:BoundField DataField="SrNo" HeaderText="SrNo" ReadOnly="true" />
                <asp:TemplateField HeaderText="CustomerFieldName">
                        <ItemTemplate>
                            <asp:Label ID="Label4" Runat="server" Text='<%# Bind("CustomerFieldName") %>'></asp:Label>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("CustomerFieldName") %>'>
                        </asp:TextBox>
                        </EditItemTemplate>
                     </asp:TemplateField>
                     <asp:BoundField DataField="CompanyFieldName" HeaderText="CompanyFieldName" ReadOnly="true" />
                     <asp:BoundField DataField="Usage" HeaderText="Usage" ReadOnly="true" />
                </Columns>
            </asp:GridView>
