The quantity that i enter loses its value after i press the submit button.</p> <pre><code>&lt;asp:GridView ID="gvSelected" runat="server" AutoGenerateColumns = "False" Font-Names = "Arial" CssClass="gridviewsSmall" Font-Size = "11pt" OnRowDataBound="GridView_gvSelected_RowDataBound" EnableViewState="False" EmptyDataText = "No Records Selected" &gt; &lt;Columns&gt; &lt;asp:BoundField DataField="ProductId" HeaderText="Product ID" ReadOnly="True" SortExpression="ProductId" /&gt; &lt;asp:TemplateField HeaderText="Product No" SortExpression="ProductNo"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="Label2" runat="server" Text='&lt;%# Bind("ProductNo") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Product Name" SortExpression="Product_name"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="Label3" runat="server" Text='&lt;%# Bind("Product_name") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:BoundField DataField="SupplierId" HeaderText="Supplier ID" ReadOnly="True" SortExpression="SupplierId" /&gt; &lt;asp:TemplateField HeaderText="Quantity" SortExpression="Quantity"&gt; &lt;ItemTemplate&gt; &lt;asp:TextBox ID="TextBox1" runat="server" Text='&lt;%#Bind("Quantity") %&gt;'&gt;&lt;/asp:TextBox&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;asp:Button ID="btnSendOrder" Visible="false" runat="server" Text="Send Order" onclick="btnSendOrder_Click" /&gt; </code></pre> <p>Here is my code behind for adding rows in gvSelected gridview</p> <pre><code> private DataTable CreateDataTable() { DataTable dt = new DataTable(); dt.Columns.Add("ProductId"); dt.Columns.Add("ProductNo"); dt.Columns.Add("Product_name"); dt.Columns.Add("SupplierId"); dt.Columns.Add("Quantity"); dt.AcceptChanges(); return dt; } private DataTable AddRow(GridViewRow gvRow, DataTable dt) { DataRow[] dr = dt.Select("ProductId = '" + gvRow.Cells[3].Text + "'"); if (dr.Length &lt;= 0) { dt.Rows.Add(); dt.Rows[dt.Rows.Count - 1]["ProductId"] = gvRow.Cells[3].Text; dt.Rows[dt.Rows.Count - 1]["ProductNo"] = (gvRow.FindControl("Label2") as Label).Text; dt.Rows[dt.Rows.Count - 1]["Product_name"] = (gvRow.FindControl("Label3") as Label).Text; dt.Rows[dt.Rows.Count - 1]["SupplierId"] = (gvRow.FindControl("Label5") as Label).Text; dt.Rows[dt.Rows.Count - 1]["Quantity"] = 0; dt.AcceptChanges(); } return dt; } protected void CheckBox_CheckChanged(object sender, EventArgs e) { GetData(); SetData(); BindSecondaryGrid(); } private void BindSecondaryGrid() { DataTable dt = (DataTable)ViewState["SelectedRecords"]; gvSelected.DataSource = dt; gvSelected.DataBind(); } </code></pre> <p>And here is the submit button!</p> <pre><code>protected void btnSendOrder_Click(object sender, EventArgs e) { t_supplier_orders newOrder = new t_supplier_orders(); newOrder.UserName = User.Identity.Name; newOrder.Order_date = DateTime.Now; newOrder.Order_status = "Pending"; MembershipUser myObject = Membership.GetUser(); Guid UserID = new Guid(myObject.ProviderUserKey.ToString()); newOrder.UserId = UserID; newOrder.SupplierId = Convert.ToInt32(ddl1.SelectedValue); newOrder.Received_date = null; Bohemian.t_supplier_orders.AddObject(newOrder); Bohemian.SaveChanges(); //------------------------------------------------------------------------+ // Create a new OderDetail Record for each item in the gvSelected | //------------------------------------------------------------------------+ foreach (GridViewRow row in gvSelected.Rows) { { t_supplier_orders_details od = new t_supplier_orders_details(); TextBox txt1 = (TextBox)gvSelected.FindControl("TextBox1"); od.OrderId = newOrder.OrderId; od.ProductId = Convert.ToInt32(row.Cells[0].Text); od.Product_name = (row.FindControl("Label3") as Label).Text; od.ProductNo = (row.FindControl("Label2") as Label).Text; od.Quantity = Convert.ToInt32(txt1.text); Bohemian.t_supplier_orders_details.AddObject(od); } } Bohemian.SaveChanges(); lblSuccess.Text = "The Order has been successfully sent to supplier!!"; lblSuccess.ForeColor=System.Drawing.Color.BlueViolet; lblSuccess.Font.Bold = true; } </code></pre>

    1. COwhere in your code are you checking `if(IsPostBack()){}`? also make sure you have viewstate enabled for that TextBox Property, another alternative would be to use Session variables. also edit your `Tags` to show asp.net

    2. CO@Haris...I think you just have a small error. You have: od.ProductNo = (row.FindControl("Label2") as Label).Text; in your submit button. od.Quantity = Convert.ToInt32(txt1.text); for the Quantity od.Quantity = Convert.ToInt32((row.FindControl("txt1") as TextBox).Text);

    3. CO@Haris...this code TextBox txt1 = (TextBox)gvSelected.FindControl("TextBox1"); won't find the control you are looking for as they TextBos is per row not the gridview

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
