Hi,

One way is to use SqlDataSource as data source of the GridView and set AutoGenerateEditButton to true. And set UpdateCommand attribute of SqlDataSource to your update statement.

GridView will display a column with Edit button that you can use to update its data to the database.

<asp:GridView
    ID="GridView1"
    runat="server"
    AutoGenerateColumns="False"
    DataKeyNames="DepartmentID"
    DataSourceID="SqlDataSource1"
    AutoGenerateEditButton="true">
    <Columns>
        <asp:BoundField DataField="DepartmentID" HeaderText="DepartmentID"
            InsertVisible="False" ReadOnly="True" SortExpression="DepartmentID" />
        <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
    </Columns>
</asp:GridView>

<asp:sqldatasource xmlns:asp="#unknown">
    ID="SqlDataSource1" 
    runat="server" 
    ConnectionString="<%$ ConnectionStrings:pagingConnectionString %>" 
    SelectCommand="SELECT [DepartmentID], [Name] FROM [Departments]"
    UpdateCommand="UPDATE Departments SET Name=@Name WHERE DepartmentID=@DepartmentID">
</asp:sqldatasource>

<
<asp:gridview id="GridView1" runat="server" onrowdeleting="GridView1_RowDeleting" xmlns:asp="#unknown">
            OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit"
            Style="margin-bottom: 0px" AutoGenerateColumns="False" ForeColor="#CC0099" GridLines="Vertical">
        


<asp:templatefield itemstyle-width=""50px"" headertext=""Edit"><br" mode="hold" />                    <ItemTemplate>
                        <asp:LinkButton ID="lbtnedit" runat="server" ForeColor="#0C4375" Text="Edit" CommandName="Edit"></asp:LinkButton>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:LinkButton ID="lbtnupdate" runat="server" ForeColor="#0C4375" Text="Update"
                            CommandName="Update"></asp:LinkButton>
                        <asp:LinkButton ID="lbtncancel" runat="server" ForeColor="#0C4375" Text="Cancel"
                            CommandName="Cancel"></asp:LinkButton>
                    </EditItemTemplate>
                    <ItemStyle Width="50px"></ItemStyle>
                </asp:TemplateField></asp:gridview>
