automatic comma in textboxes - asp.net

Question

Actually commas are perfectly executed in the text box. 12345=12,345
However my submit button is not functioning well when i am declaring the javascrip with my textbox:
<asp:TextBox ID="txtProductPrice" runat="server" class="form-control" MaxLength ="6" onkeyup ="javascript:this.value=Comma(this.value);"></asp:TextBox>
here is my button code:
protected void btnSubmit_Click(object sender, EventArgs e)
{
if (uploadProductPhoto.PostedFile != null)
{
SaveProductPhoto();
ShoppingCart k = new ShoppingCart()
{
ProductName = txtProductName.Text,
ProductImage = "~/ProductImages/" + uploadProductPhoto.FileName,
ProductPrice = txtProductPrice.Text,
ProductDescription = txtProductDescription.Text,
CategoryID = Convert.ToInt32(ddlCategory.SelectedValue),
TotalProducts = Convert.ToInt32(txtProductQuantity.Text)
};
k.AddNewProduct();
ClearText();
Label2.Text = "Product Added!";
//Response.Redirect("AddNewProduct.aspx?alert=success");
}
else
{
Response.Write("<script>alert('Please upload photo');</script>");
The code is finished ("Product Added" is showing up) however, the product is not actually added. its not in the database or anywhere. any tricks on this?
here is the k.AddNewProduct();
ALTER PROCEDURE [dbo].[SP_AddNewProduct]
(
#ProductName varchar(300),
#ProductPrice varchar(500),
#ProductImage varchar(500),
#ProductDescription varchar(1000),
#CategoryID int,
#ProductQuantity int
)
AS
BEGIN
BEGIN TRY
Insert into products
values
(#ProductName,
#ProductDescription,
#ProductPrice,
#ProductImage,
#CategoryID,
#ProductQuantity
)
END TRY
BEGIN CATCH
PRINT ('Error Occured')
END CATCH
END

I have js by using simplified regex
function Comma(Num) {
var parts = Num.toString().split(".");
parts[0] = parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",");
return parts.join(".");
}
if you also need support for numbers with decimals then use the below code
function numberWithCommas(n) {
var parts=n.toString().split(".");
return parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",") + (parts[1] ? "." + parts[1] : "");
}
