Editing Selected GridView Row using Textboxes (in a div)

Question

Hello.

 

I am wondering how I can edit a selected row (by a link button) by showing the cell values in textboxes.

 

I have this code so far.

ASP.NET
-----------------
<!--Invisible textboxes for editing-->

<div id="div1" runat="server" visible="false">

                        <table cellpadding="2" cellspacing="1" class="cont-table">                            

                            <tr>

                                <td class="header" style="width:150px;">Leave Type</td>

                                <td class="cont" style="padding:5px; width:300px;">

                                    <asp:Textbox ID="txtLeaveType" runat="server" AutoPostBack="false" Font-Size="12px" Enabled="False" Width="290px">

                                    </asp:Textbox>

                                </td>                            

                                <td class="header" style="width:150px;"> Application Date</td>

                                <td class="cont" style="padding:5px;">

                                    <asp:TextBox ID="txtEffAppDate" runat="server"  Font-Size="12px"  Enabled="False"  Width="150"></asp:TextBox> &nbsp;

                                </td>

                            </tr>
</table>

<!--grid view-->

<asp:GridView ID="EmpLeaveAppGV1" CssClass="datagrid gridfont" runat="server" AutoGenerateColumns="False" GridLines="none"  

                            CellPadding="4" ForeColor="#333333" EmptyDataText= "No current record found in the database." Width="868px" OnRowCommand="GridViewRowCommand"><%--OnRowDeleting="EmpLeaveAppGV1_SelectedIndexChanged"--%>

                        <SelectedRowStyle BackColor="#CCCCCC" Font-Bold="True" ForeColor="#333333" />

                        <Columns>

                                <asp:TemplateField HeaderStyle-BorderStyle="None" ItemStyle-Width="45" ItemStyle-CssClass="right-shadow" ItemStyle-HorizontalAlign="Center">

                                    <Itemtemplate>

                                        <asp:LinkButton ID ="lbtnEmpHist" ToolTip="Edit" CssClass="edit-item" runat="server" CommandName="EditPending" ForeColor="Blue"></asp:LinkButton>

                                        <asp:LinkButton ID="lbtnEmpStatus" ToolTip="Delete" CssClass="delete-item" runat="server" CommandName="Delete" ForeColor="Aquamarine"></asp:LinkButton>

                                    </Itemtemplate>

                                </asp:TemplateField>

                                <asp:TemplateField HeaderText="Employee Name" HeaderStyle-HorizontalAlign="left"  HeaderStyle-BorderStyle="None" ItemStyle-HorizontalAlign="left" ItemStyle-Width="160">

                                   <ItemTemplate>

                                        <asp:Label ID="lblEmpNameFull" runat="server" Text='<%# Bind("EmpNameFull") %>'></asp:Label>

                                    </ItemTemplate>

                                </asp:TemplateField>

-----------------

C# Code Behind
------------

 protected void GridViewRowCommand(Object sender, GridViewCommandEventArgs e)

    {

        if (e.CommandName=="EditPending")

        {

            int LeaveTranID = Convert.ToInt32(e.CommandArgument);

           int rowindex = EmpLeaveAppGV1.SelectedIndex;

            Label lblLeaveType = (Label)(EmpLeaveAppGV1).Rows[rowindex].FindControl("lblLeaveType");

           

            txtLeaveType.Text = lblLeaveType.Text;

           

           

            div1.Visible = true;

        }

    }

------------

  using (GridViewRow row = (GridViewRow)((LinkButton)sender).Parent.Parent)
