ASP.NET is a powerful programming language that allows developers to create dynamic web applications. One common requirement in web development is to have a calendar control that displays the current date by default. In this article, we will explore how to achieve this using ASP.NET and provide examples to illustrate the process.
To begin, let's take a look at the ASP.NET code snippet below:
This code creates a calendar control in ASP.NET. By default, the calendar control will display the current month and year. However, the selected date will not be set to the current date. To achieve this, we need to add some additional code.
Setting the Default Date
To set the default date to the current date, we can use the `SelectedDate` property of the calendar control. We can do this in the code-behind file of our ASP.NET page.
First, let's add the following code snippet to the Page_Load event:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
calendarControl.SelectedDate = DateTime.Now;
}
}
In this code, we check if the page is being loaded for the first time (i.e., not a postback). If it is the first load, we set the `SelectedDate` property of the calendar control to the current date using `DateTime.Now`.
Displaying the Selected Date
Now that we have set the default date to the current date, we may want to display the selected date to the user. We can achieve this by adding a label control to our ASP.NET page.
Let's add the following code snippet to our ASP.NET page:
Next, we need to update the Page_Load event to display the selected date in the label control:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
calendarControl.SelectedDate = DateTime.Now;
selectedDateLabel.Text = "Selected Date: " + calendarControl.SelectedDate.ToShortDateString();
}
}
In this code, we set the `Text` property of the label control to display the selected date. We concatenate the string “Selected Date: ” with the formatted date using `ToShortDateString()`.
Conclusion
In this article, we have explored how to select the current date by default in an ASP.NET calendar control. By setting the `SelectedDate` property to `DateTime.Now`, we can ensure that the calendar control displays the current date when the page is loaded. Additionally, we have demonstrated how to display the selected date using a label control. ASP.NET provides a robust set of tools and features to create dynamic web applications, and the calendar control is just one example of its versatility.
