Highlight Weekend Dates in Calendar Control in ASP.NET

In this blog, I explained how to how to highlight a weekend days or a specific days in ASP.NET calender control.

Steps

Create new ASP.NET Empty Web Application give it to meaning full name.
Add new webfrom to your project.
Drag and drop Calendar on your design page.
Add two properties WeekendDayStyle-BackColor="Yellow", WeekendDayStyle-ForeColor="Black" to your calender control as shown below and run your application.

<asp:Calendar ID="Calendar1" runat="server"
WeekendDayStyle-BackColor="Yellow"
WeekendDayStyle-ForeColor="Green" ></asp:Calendar>

Output

You can achieve the same by using (OnDayRender event) code as mentioned below. Remove WeekendDayStyle-BackColor="Yellow", WeekendDayStyle-ForeColor="Green" from Calender control.

.aspx

<asp:Calendar ID="Calendar1" runat="server" OnDayRender="Calendar1_DayRender"></asp:Calendar>

CodeBehind:

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (e.Day.IsWeekend)
{
e.Cell.BackColor = System.Drawing.Color.Yellow;
e.Cell.ForeColor = System.Drawing.Color.Green;
}
}

If you want to Highlight on 'Monday' write the following code in Calendar1_DayRender event. It highlights the the specified day dates.

if (e.Day.Date.DayOfWeek == DayOfWeek.Monday)
{
e.Cell.BackColor = System.Drawing.Color.Yellow;
e.Cell.ForeColor = System.Drawing.Color.Green;
}
