Is it possible to write asp net website which will call a telephone number by s

ASP.NET is a powerful that allows developers to create and interactive websites. One common question that arises when working with ASP.NET is whether it is possible to write a website that can call a telephone number. In this article, we will explore this question and examples to demonstrate how it can be achieved.

To begin with, let's take a look at the basic structure of an ASP.NET website. ASP.NET uses a combination of HTML and server-side code to create web . The server-side code is written in C# and is executed on the server before the page is sent to the client's browser.

To call a telephone number from an ASP.NET website, we can make use of the tel: URI scheme. This scheme allows us to specify a telephone number in a hyperlink, which when clicked, will initiate a call to that number. Let's see an example of how this can be done in ASP.NET.

Example 1: Calling a Telephone Number

Suppose we have a button on our website that, when clicked, should call a specific telephone number. We can achieve this by using the tel: URI scheme in the button's hyperlink.



In the code above, we have a button with the ID “btnCall” and a text “Call”. We have also specified an event handler “btnCall_Click” for the button's click event.


protected void btnCall_Click(object sender, EventArgs e)
{
    string phoneNumber = "1234567890";
    string url = "tel:" + phoneNumber;
    Response.Redirect(url);
}

In the event handler “btnCall_Click”, we first specify the telephone number we want to call (in this case, “1234567890”). We then construct the tel: URI by concatenating the telephone number with the “tel:” prefix. Finally, we use the Response.Redirect to redirect the user's browser to the tel: URI, which will initiate the phone call.

Example 2: Calling a Telephone Number with User

In some cases, we may want to allow the user to enter a telephone number and then call that number. We can achieve this by using an input and a button.




In the code above, we have an input field with the ID “txtPhoneNumber” and a button with the ID “btnCall”. We have also specified the event handler “btnCall_Click” for the button's click event.


protected void btnCall_Click(object sender, EventArgs e)
{
    string phoneNumber = txtPhoneNumber.Text;
    string url = "tel:" + phoneNumber;
    Response.Redirect(url);
}

In the event handler “btnCall_Click”, we retrieve the telephone number entered by the user from the input field “txtPhoneNumber”. We then construct the tel: URI using the user-provided telephone number and redirect the user's browser to initiate the phone call.

In conclusion, it is indeed possible to write an ASP.NET website that can call a telephone number. By using the tel: URI scheme and the Response.Redirect method, we can create buttons or input fields that, when interacted with, initiate phone to specified telephone numbers.
