First of all I have to say I'm a beginner. I'm developing a music shop for my college product in asp.net C#.
I encoded the URL for the path http://localhost:1375/~/Pages/Product.aspx?id=2
by
a = Server.UrlEncode(string.Format("~/Pages/Product.aspx?id={0}",product.Id));
And I get error 404:
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
I know I have to decode the encoded URL somewhere, but I'm confused where. I'm giving the code below:
Index.aspx
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Index : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string a;
ProductModel model = new ProductModel();
List<Product> products = model.GetAllProducts();
if (products != null)
{
foreach (Product product in products)
{
Panel productPanel = new Panel();
a = Server.UrlEncode(string.Format("~/Pages/Product.aspx?id= {0}",product.Id));
ImageButton imageButton = new ImageButton
{
ImageUrl = "~/ABCDIMGS/img/" + product.Image,
CssClass = "productImage",
PostBackUrl = a
};
Label lblName = new Label
{
Text = product.Name,
CssClass = "productName"
};
Label lblPrice = new Label
{
Text = "$ " + product.Price,
CssClass = "productPrice"
};
productPanel.Controls.Add(imageButton);
productPanel.Controls.Add(new Literal { Text = "<br/>" });
productPanel.Controls.Add(lblName);
productPanel.Controls.Add(new Literal { Text = "<br/>" });
productPanel.Controls.Add(lblPrice);
//Add dynamic controls to static control
pnlProducts.Controls.Add(productPanel);
}
}
else
pnlProducts.Controls.Add(new Literal { Text = "No products found!" });
}
}

{

if (clientId != null)
{

ClientID = clientId,

};

}
else
{

}
}
}
private void FillPage()
{
//Get selected product data
if (!string.IsNullOrWhiteSpace(Request.QueryString["id"]))
{
int id = Convert.ToInt32(Request.QueryString["id"]);
ProductModel model = new ProductModel();
Product product = model.GetProduct(id);
//Fill page with data
lblTitle.Text = product.Name;
lblDescription.Text = product.Description;
lblPrice.Text = "Price per unit:<br/>$ " + product.Price;
imgProduct.ImageUrl = "~/ABCDIMGS/img/" + product.Image;
lblItemNr.Text = product.Id.ToString();
//Fill amount list with numbers 1-20
int[] amount = Enumerable.Range(1, 20).ToArray();
ddlAmount.DataSource = amount;
ddlAmount.AppendDataBoundItems = true;
ddlAmount.DataBind();
}
}
}
