ASP.Net is a powerful and versatile web development framework that is widely used to create dynamic and interactive websites. One of the key features of ASP.Net is its ability to handle form data, making it the perfect choice for implementing search forms. In this article, we will explore how to use ASP.Net to create a search form with the "get" method.
Before we dive into the technical details, let's first understand what the "get" method is and why it is useful for search forms. The "get" method is one of the two methods used to submit form data in HTML. It is primarily used for retrieving data from a server, making it a perfect fit for search forms where the user is looking for specific information. The "get" method appends the form data to the URL, making it visible in the browser's address bar. This not only makes it easy for the user to share the search results with others but also allows them to bookmark the results for future reference.
Now, let's get started with implementing a search form using the "get" method in ASP.Net. The first step is to create a new ASP.Net project and add a web form to it. We will name the web form "search.aspx". Next, we will add the necessary HTML tags to create a form. The <form> tag will contain the "get" method and the action attribute, which specifies the URL of the page that will process the form data. In our case, it will be the same page, i.e., "search.aspx". We will also add a <label> tag and an <input> tag with the type attribute set to "text" to create a text input field for the user to enter their search query.
Once the form is set up, we need to handle the form data on the server-side. ASP.Net provides a built-in class called "Request" that allows us to retrieve the form data. We will use the "Request.QueryString" property to access the form data passed through the URL. This property returns a collection of key-value pairs, where the key is the name of the form field, and the value is the user's input. In our case, the form field name will be "search" as specified in the <input> tag's name attribute. We will retrieve the user's input and store it in a variable called "query". This variable will then be used to perform the search operation and display the results on the page.
To display the search results, we will use ASP.Net's <asp:Repeater> control. This control allows us to display data in a tabular format, making it perfect for displaying search results. We will bind the repeater control to a data source, which can be a database or a collection of objects. In our case, we will use a dummy data source to keep things simple. The data source will contain a list of products, and we will display the products that match the user's search query. We will also use the <asp:HyperLink> control to create a link for each product, which will take the user to the product's details page.
With all the code in place, we can now run our application and test the search form. We will enter a search query in the text input field and hit the "Search" button. The form data will be appended to the URL, and the page will reload, displaying the search results. The user can also
