What? You have the code to remove a panel but you can't figure out how to Add a panel?

Where are you stuck? Put a textbox or a label or some control and then put the category in the textbox or label. Simple.

Always use Reply button, to post Comments/query to the user, so that the user gets notified and responds to your text.

Rather than adding a category control you should have the category always there and populate it with the relevant text if you need to show it, and if you don't need to show it then set its visibility to hidden, or remove it the way you're removing the button.

Ya know, I would probably write that code like this, because it's easier to read the if statement. It calls the extension method shown at the end of this solution:

C#

if (cat != null)
{
    DateTime start = (cat.StartTime.HasValue) ? cat.StartTime.Value.SetSeconds() : new DateTime(0);
    DateTime end = (cat.EndTime.HasValue) ? cat.EndTime.Value.SecSeconds() : new DateTime(0);
    DateTime now = DateTime.Now;

    bool inRange = (start <= now && end >= now);
    if (!(start <= now && end >= now))
    {
        flpCategories.Controls.Remove(ctrl);
    }
}

As for showing a control when inRange is true, simply set the visible flag for the control. Since you didn't specify the framework (WinForms, WPF, ASP.Net), I'll leave it to you to find the appropriate way to do that.

If you're interested, I wrote a tip/trick that allows you to compare the desired parts of two DateTime objects:

Partial DateTime Object Equality[^]

And btw, here's a handy extension method for setting the seconds from a DateTime. calling it with no parameters will automatically return the date value with the seconds and milliseconds to 0.

C#

public static DateTime SetSeconds(this DateTime date, double secs=0, double millisecs=0)
{
    return new DateTime(date.Year, date.Month, date.Day, date.Hour, date.Minute, secs, millisecs, date.Kind);
}
