Asp net vb changing a url parameter from vaiable value to simply value

Introduction

ASP.NET is a popular programming language used for dynamic web applications. One common task in web development is changing a URL parameter from a variable value to a simple value. In this article, we will explore how to achieve this ASP.NET with examples.

Let's say we have a URL with a parameter “id” that represents the ID of a product. The URL looks like this:

https://example.com/product?id=123

In this example, the value of the “id” parameter is set to 123. However, we want to change it to a simple value, such as “product-123”.

Solution

To achieve this, we can use the ASP.NET routing . Routing allows us to define custom URL and map them to specific actions or controllers in our application.

First, we need to configure the routing in our ASP.NET application. This can be done in the RouteConfig.cs file, which is typically located in the App_Start folder. Open the file and add the following code:

 static void RegisterRoutes(RouteCollection routes)
{
    routes.MapPageRoute("ProductRoute", "product-{id}", "~/Product.aspx");
}

In the above code, we define a route called “ProductRoute” that maps the URL pattern “product-{id}” to the “Product.aspx” page. The “{id}” represents the value of the “id” parameter.

Next, we need to update the link in our application to use the new URL pattern. In our example, we can update the link to the product page as follows:

In the above code, we use the Page.GetRouteUrl to generate the URL based on the “ProductRoute” route and the parameter values. In this case, we set the “id” parameter to 123.

When the link is rendered in the browser, it will have the following URL:

https://example.com/product-123

By using routing, we have successfully changed the URL parameter from a variable value to a simple value.

Conclusion

In this article, we have explored how to change a URL parameter from a variable value to a simple value using ASP.NET. By leveraging the routing feature, we can define custom URL patterns and map them to specific actions or controllers in our application. This allows us to create more user-friendly and SEO-friendly URLs.
