Edit Gridview Row ASP.net

Struggling to edit a Gridview Row. Once I hit edit the gridview disappears, I guess because I only bind the grid on !IsPostBack - although the tutorial tells me to do it this way.
I have tried rebinding on postback which lets me edit the gridview but keeps the default values - not the new values.
Any help appreciated.
if (!IsPostBack)
{
if (Session["Order_ID"] != null)
{
showgrid(int.Parse(Session["Order_ID"].ToString()));
}
}
public void showgrid(int Order_ID)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDbConn"].ToString());
string sqlstring = "Removed - is working";
SqlCommand cmd = new SqlCommand(sqlstring, conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
conn.Close();
if (ds.Tables[0].Rows.Count > 0)
{
gv_ExistingAds.DataSource = ds;
gv_ExistingAds.DataBind();
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
gv_ExistingAds.EditIndex = e.NewEditIndex;
showgrid(int.Parse(Session["Order_ID"].ToString()));
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
Label lb = (Label)gv_ExistingAds.Rows[e.RowIndex].FindControl("Label3");
TextBox tx1 = (TextBox)gv_ExistingAds.Rows[e.RowIndex].FindControl("TextBox3");
string tx11 = tx1.Text;
gv_ExistingAds.EditIndex = -1;
showgrid(int.Parse(Session["Order_ID"].ToString()));
}

You only have one EditItemTemplate element for the first TemplateField, you need an EditItemTemplate element for each TemplateField that you want to be editable, like this:

Binding Shopping Cart Check box Session onto another Gridview

I am new to asp.net and I am trying to make a shopping cart. I have a shop set up that has a list of school supplies and a check box next to each one with a "Add to Cart" button on the bottom. I want to store only the checked items into a session and call it to another gridview on my Shopping Cart page. For some reason my gridview on my Shopping cart page is not appearing.
Shop.aspx

ShoppingCart.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
DataTable dt = (DataTable)Session["ShoppingCart"];
gvProductsList.DataSource = dt;
gvProductsList.DataBind();
}
}

Try this:-
List<GridViewRow> gridcheckedrows = gvProducts.Rows.Cast<GridViewRow>().
Where(x => (x.FindControl("cbAdd") as CheckBox)
.Checked == true).ToList();
I used below custom data to bind the grid gvProducts
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("Id");
dt.Columns.Add("Name");
dt.Columns.Add("Price");
DataRow dr = dt.NewRow();
dr[0] = "1";
dr[1] = "Sharique";
dr[2] = "120";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "2";
dr[1] = "Ansari";
dr[2] = "100";
dt.Rows.Add(dr);
gvProducts.DataSource = dt;
gvProducts.DataBind();
}
}
use this to bind you grid gvProductsList
List<GridViewRow> gridcheckedrows = gvProducts.Rows.Cast<GridViewRow>().Where(x => (x.FindControl("cbAdd") as CheckBox).Checked == true).ToList();
DataTable dt = new DataTable();
dt.Columns.Add("Id");
dt.Columns.Add("Name");
dt.Columns.Add("Price");
dt.Columns.Add("Count");
dt.Columns.Add("Quantity");
foreach (GridViewRow gvr in gridcheckedrows)
{
DataRow dr = dt.NewRow();
dr["Id"] = gvr.Cells[0].Text;
dr["Name"] = gvr.Cells[1].Text;
dr["Price"] = gvr.Cells[2].Text;
dr["Count"] = "1";
dr["Quantity"] = "2";
dt.Rows.Add(dr);
}
gvProductsList.DataSource = dt;
gvProductsList.DataBind();
and for grid gvProductsList use below html
<asp:GridView ID="gvProductsList" runat="server">
<Columns>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%# Bind("ID")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="lblName" runat="server" Text='<%# Bind("Name")%>'></asp:Label>

<asp:TemplateField HeaderText="Price">

protected void updateBack()
{
Response.Write(I want to get the deleted seatOrderID here!!!!!);
}

Using this code, you can fetch the ID in the RowDeleting event:
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridViewRow gvr = (GridViewRow)GridView1.Rows[e.RowIndex];
string id = String.Empty;
Label lbl = (gvr.FindControl("Label1") as Label)
if (lbl != null)
{
id = lbl.Text;
}
}
You can fetch any control in the row, using the FindControl() method.

How to bind hovermenuextender control to a row with multiple columns in a dynamic gridview?

I wish to attach a hovermenu pop up to rows of a gridview which is dynamically populated from a datasource. I tried to set TargetcontrolId property of hovermenuextender control to row unique Id on occurence of rowdatabound event. But rather than appearing on the right side of each row, pop up is appearing on the right side of header row. Can somebody help me resolve this problem? I used below code for the same

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)

if (hoverMenu != null)
{
hoverMenu.TargetControlID = hoverMenu.Parent.Parent.UniqueID;
}
}
