Order Version problem in session

Question

Following error is getting displayed while udpating the order:
Saving order 804880053 failed because doing so would result in data being overwritten. Order data for your browser window was out of date. Please re-submit your changes for them to take effect.
My order is getting update in CSC and after that again I'm updating my order in StoreSite, in that perticular scenario only this error is coming.
I have also used below code before updating the order in store site:
itemDesImpl = (ItemDescriptorImpl)rep.getItemDescriptor("order");
itemDesImpl.removeItemFromCache(orderId);
and
oImpl.invalidateOrder();
but It only removes cache data not session data and I think the problem is due to session data of order. If I would be able to remove order from session also, I guess I'm done with that error.
As per my understanding below places order data exists:
1. Session
2. Cache
3. Database
Please help me out!

Answer 1

Hai,
I'm using VS2010 and SQL Server 2005.
I have a problem in Session state.
See below is my code,
//View.aspx.cs
//Here I assign a textbox value to session
protected void btnEdit_Click(object sender, EventArgs e)
        Session["rollno"] = txtRollNo.Text;
            Response.Redirect("Edit.aspx");
//Edit.aspx.cs
//Here I assign a session value to textbox, which is stored in last page.
protected void Page_Load(object sender, EventArgs e)
        txtRollNo.Enabled = false;
        txtRollNo.Text = Session["rollno"].ToString();
        getdata();
public void getdata()
        SqlConnection con = new SqlConnection("Data Source=SERVICETEAM-PC;Initial Catalog=csc;User ID=sa;Password=kavi");
        con.Open();
        SqlCommand cmd = new SqlCommand("Select * from Csc where Roll_No='" + txtRollNo.Text + "'", con);
        SqlDataReader dr = cmd.ExecuteReader();
        if (dr.Read())
            txtName.Text = dr.GetString(1).ToString();
            txtAddress.Text = dr.GetString(2).ToString();
            txtMobileNo.Text = dr.GetString(3).ToString();
            txtYesNo.Text = dr.GetString(4).ToString();
From the above code If I the Edit button, It will show an error like
