How to highlight current date in calendar control in asp.net C#, VB

Introduction: In this article I will explain how to highlight current/today's date in asp.net calendar using code behind or by setting the calendar's attributes in asp.net using both C# and VB languages.

Source Code:

In the design page, place a calendar control and set its attributes as shown below: 

<asp:Calendar ID="Calendar1"

         runat="server"

         TodayDayStyle-BackColor="Yellow"

         TodayDayStyle-ForeColor="Red"

         TodayDayStyle-Font-Bold="true"

         TodayDayStyle-Font-Size="20px">

</asp:Calendar>

Or (Output will be same)

<asp:Calendar ID="Calendar1"

         runat="server">

         <TodayDayStyle BackColor="Yellow" ForeColor="Red" Font-Bold="true" Font-Size="20px" />

         </asp:Calendar>

Asp.Net C# Code to highlight current date in calendar control

 write the code as:

  protected void Page_Load(object sender, EventArgs e)

    {

        if (!Page.IsPostBack)

        {

            Calendar1.SelectedDate = System.DateTime.Now;

           // or you can also set the current date as:

           Calendar1.TodaysDate = System.DateTime.Now;

        }

    }

You can also set the TodayDayStyle property from code as:

  protected void Page_Load(object sender, EventArgs e)

    {

        if (!Page.IsPostBack)

        {

            Calendar1.SelectedDate = System.DateTime.Now;

            Calendar1.TodayDayStyle.BackColor = System.Drawing.Color.Yellow

            Calendar1.TodayDayStyle.ForeColor = System.Drawing.Color.Red

            Calendar1.TodayDayStyle.Font.Bold = True

        }

    }

Asp.Net VB Code to highlight current date in calendar control

Write the code as:

   Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

        If Not Page.IsPostBack Then        

            Calendar1.SelectedDate = System.DateTime.Now

           // or you can also set the current date using the line below:                                                                     Calendar1.TodaysDate = System.DateTime.Now

        End If

    End Sub

 You can also set the TodayDayStyle property from code as:

   Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

        If Not Page.IsPostBack Then        

            Calendar1.SelectedDate = System.DateTime.Now

            Calendar1.TodayDayStyle.BackColor = System.Drawing.Color.Yellow

            Calendar1.TodayDayStyle.ForeColor = System.Drawing.Color.Red

            Calendar1.TodayDayStyle.Font.Bold = True

        End If

    End Sub
