Is it possible to bold the day text in the radcalendar based on certain events? For example, I want to "lock" certain dates, say from Dec. 1st to Dec. 20th and to show that they are "locked" i want to bold the day text for days 1 - 20 in the calendar.  To "lock" these days I would click a button, for example, and the selected date and all dates prior would be bolded (locked).  Is it possible to do this?

Hello Brennan,

Thank you for writing.

You can subscribe to the ElementRender event of RadCalendar. In this event you can define the style of the font:
void radCalendar1_ElementRender(object sender, RenderElementEventArgs e)
{
    if (e.Day.Date == new DateTime(2010, 9, 6))
    {
        Font font = new Font(e.Element.Font, e.Element.Font.Style | FontStyle.Bold);
        e.Element.Font = font;
    }
    else
    {
        Font font = new Font(e.Element.Font, e.Element.Font.Style & ~FontStyle.Bold);
        e.Element.Font = font;
    }
}

I hope that this will help you. If you have other questions, feel free to write back.

Hi!

I'm using that event you mentioned to color font in Cell (e.Element.Text = "Text"; e.Element.ForeColor=Color.Red;), and it works fine when I change month in calendar. But this event seems not to fire after RadCalendar is created and shown. How to force to fire ElementRender event after control is crated and shown?

Best Regards,
Tomasz.

Hello Tim,

Thank you for contacting Telerik Support.

In order to refresh the calendar after it is initialized, you may use the following code snippet:
public Form1()
{
    InitializeComponent();
 
    radCalendar1.InvalidateCalendar();
}
 
private void radCalendar1_ElementRender(object sender, RenderElementEventArgs e)
{
    if (e.Day.Date > new DateTime(2013, 11, 6) && e.Day.Date < new DateTime(2013, 11, 26))
    {
        Font font = new Font(e.Element.Font, e.Element.Font.Style | FontStyle.Bold);
        e.Element.Font = font;
    }
    else
    {
        Font font = new Font(e.Element.Font, e.Element.Font.Style & ~FontStyle.Bold);
        e.Element.Font = font;
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,
Desislava
