Adding multiple data from list view

I have a listview that tells the quantity ordered and quantity that has been delivered. I have complete added the first row, but the succeeding rows are not added. I want to add multiple records in one click. I have an add button outside the list view to do the job
Here is the list view of the form
<asp:ListView ID="lvPODetails" runat="server">
<ItemTemplate>
<tr>
<td>
<asp:Label ID="lblProduct" runat="server" type="number" Text='<%# Eval("RefNo")%>' class="form-control" Visible ="false" />
<%# Eval("ProductName") %>
</td>
<td>
<%# Eval("Price", "{0: #,###.00}") %>
</td>
<td><asp:TextBox ID="txtOrdered" runat="server" type="number" Text='<%# Eval("DesiredQuantity") %>' readonly="true" class="form-control" /></td>
<td><asp:TextBox ID="txtQuantity" runat="server" type="number" min="1" max="1000000" Text='' class="form-control" required /></td>
<td><%# Eval("POAmount", "{0: #,###.00}") %></td>
<td><%# Eval("POAmount", "{0: #,###.00}") %></td>
</tr>
</ItemTemplate>
<EmptyDataTemplate>
<tr>
<td colspan="4"><h2 class="text-center">No records found.</h2></td>
</tr>
</EmptyDataTemplate>
</asp:ListView>
The .cs of the aspx
protected void btnAdd_Click(object sender, EventArgs e)
{
bool existingSupply = IsExisting();
foreach (ListViewItem item in lvPODetails.Items)
{
TextBox quantity = (TextBox)item.FindControl("txtQuantity");
Label ltr = (Label)item.FindControl("lblProduct");
TextBox odr = (TextBox)item.FindControl("txtOrdered");
string name = ltr.Text;
int delivered = Convert.ToInt32(quantity.Text);
int ordered = Convert.ToInt32(odr.Text);
string status = String.Empty;
if (delivered >= ordered)
{
status = "Complete";
}
if (delivered < ordered)
{
status = "Partially Completed";
}
con.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
if (existingSupply)
{
cmd.CommandText = "UPDATE Inventory SET Quantity=quantity + #Quantity WHERE ProductID=#ProductID";
}
else
{
cmd.CommandText = "INSERT INTO Inventory VALUES (#ProductID, #ProdCatID, #SupplierName, " +
"#Quantity, #CriticalLevel, #Price, #Status, #DateAdded, #DateModified)";
}
cmd.Parameters.AddWithValue("#ProductID", name);
cmd.Parameters.AddWithValue("#ProdCatID", DBNull.Value);
cmd.Parameters.AddWithValue("#SupplierName", txtSupplier.Text);
cmd.Parameters.AddWithValue("#Quantity", delivered);
cmd.Parameters.AddWithValue("#CriticalLevel", DBNull.Value);
cmd.Parameters.AddWithValue("#Price", DBNull.Value);
cmd.Parameters.AddWithValue("#Status", DBNull.Value);
cmd.Parameters.AddWithValue("#DateAdded", DateTime.Now);
cmd.Parameters.AddWithValue("#DateModified", DateTime.Now);
//cmd.CommandText = "UPDATE PurchaseOrder SET POStatus=#POStatus WHERE PONo=#PONo";
//cmd.Parameters.AddWithValue("#POStatus", status);
//cmd.Parameters.AddWithValue("#PONo", txtPONo.Text);
cmd.ExecuteNonQuery();
con.Close();
Response.Redirect("Default.aspx");
}
}
I don't get it, it is not showing errors but it is not adding the next rows.

Adding 'rolling numbers' for repeater control, Paging asp.net c#

Your problem isn't that you can't access the TextBox.
Use int.TryParse instead of int.Parse since you are reading user input.
int received;
if (!int.TryParse(Received, out received) || received < 0)
{
error.Visible = true;
lblError.Text = "Items received must not be lower than zero";
}

image redirect to another form in aspx?

This is my aspx code...
<asp:DataList ID="DataList1" runat="server" RepeatColumns="3" RepeatDirection="Horizontal"
Width="88%" Height="100px">
<ItemTemplate>
<table width="0" border="0" cellpadding="0" cellspacing="1">
<tr>
<td>
<%#Eval("Coupon_Image")%>'
</td>
</tr>
<tr>
<td height="20px">
</td>
</tr>
<tr>
<td align="center">
<%--<asp:LinkButton ID="Button1" runat="server" Width="145" Height="34" border="0" CommandArgument='<%# Eval("Coupon_Id") %>'
CommandName="Get Coupoun" OnClick="getCoupon_Click"></asp:LinkButton>--%>
<asp:Button ID="getCoupon" runat="server" Width="145" Height="34" border="0" CommandArgument='<%# Eval("Coupon_Id")%>' Text="Get Coupon"
OnClick="getCoupon_Click" />
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>
my code in code behind:
private void Binddata()
{
DataTable dtReport = new DataTable();
DataColumn Coupon_Id = new DataColumn("Coupon_Id");
DataColumn Coupon_Image = new DataColumn("Coupon_Image");
dtReport.Columns.Add(Coupon_Id);
dtReport.Columns.Add(Coupon_Image);
string sendquery = "select Coupon_Id,Coupon_Image from Admin where Coupon_Status='Active'";
SqlDataAdapter da = new SqlDataAdapter(sendquery, connection);
DataSet dsProfile = new DataSet();
da.Fill(dsProfile);
for (int i = 0; i < dsProfile.Tables[0].Rows.Count; i++)
{
DataRow row = dtReport.NewRow();
row["Coupon_Id"] = dsProfile.Tables[0].Rows[i]["Coupon_Id"].ToString();
string id = dsProfile.Tables[0].Rows[i]["Coupon_Id"].ToString();
string ImgName = dsProfile.Tables[0].Rows[i]["Coupon_Image"].ToString();
string Path = "http://localhost:2872/arpita-coupons/Coupon_Image/" + ImgName ;
row["Coupon_Image"] = "<img src='" + Path + "' height='200px' width='200px' />";
hddnpath.Value = Path + ImgName + id;
dtReport.Rows.Add(row);
}
DataList1.DataSource = dtReport;
DataList1.DataBind();
}
protected void getCoupon_Click(object sender, EventArgs e)
{
string id = hddnpath.Value;
string imagename = hddnpath.Value;
Response.Redirect("deals-forms.aspx?id="+id+" & ImgName="+imagename+" "+"");
}
my question is if i click the button to get the particular image to be redirect to the another page . but i am getting only the different image to the another aspx page...

You set id and imagename to the same value, then build a link from both. I guess there is the problem somewhere:
string id = hddnpath.Value;
string imagename = hddnpath.Value;
Response.Redirect("deals-forms.aspx?id=" + id // <-- this variable
+ " & ImgName=" + imagename // <-- and this one both
+ " " + ""); // contain hddnpath.Value

Assigning same datasource to multiple DropDownLists?

I want to assign same datasource to multiple DropDownLists in a form, when the page loads, only the first drop down list has filled the content of datasource, others are empty, what's the missing point? thanks for answers. Here are the codes;

Its becasue you are using dataReader instead of this use datatable will work for you. Reader is readonly and forward only thats why only first dropdonw get filled with data and others are empty.
changed code :
protected void FillTheDropDownLists()
{
SqlApplication con = new SqlApplication();
try
{
SqlCommand cmd = new SqlCommand("SELECT name FROM BT.dbo.Cartridge ORDER BY name", con.GetConnection());
con.OpenSqlConnection();
SqlDataReader reader = cmd.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(reader );
blackList.DataValueField = "name";
blackList.DataSource = dt ;
blackList.DataBind();
colorList1.DataValueField = "name";
colorList1.DataSource = dt ;
colorList1.DataBind();
colorList2.DataValueField = "name";
colorList2.DataSource = reader;
colorList2.DataBind();
colorList3.DataValueField = "name";
colorList3.DataSource = dt ;
colorList3.DataBind();
otherColor1.DataValueField = "name";
otherColor1.DataSource = dt ;
otherColor1.DataBind();
otherColor2.DataValueField = "name";
otherColor2.DataSource = dt ;
otherColor2.DataBind();
otherColor3.DataValueField = "name";
otherColor3.DataSource = dt ;
otherColor3.DataBind();
reader.Close();
}
catch (Exception err)
{
System.Diagnostics.Debug.WriteLine("Exception: " + err.Message);
}
finally
{
con.CloseSqlConnection();
}
}

According to the documentation data reader is forward only. Use data table or read into a list and bind your combos to it.

for (int i = 1; i <= 260; i++)
{
ContentPlaceHolder maincontent = Page.Master.FindControl("MainContent") as ContentPlaceHolder;
DropDownList a = (DropDownList)maincontent.FindControl("ddl" + i);
a.DataSource = ds;
a.DataTextField = "Options";
a.DataValueField = "id";
a.DataBind();
a.Items.Insert(0, new ListItem("Select", "0", true));
}
