Question

I have a DGV bound to a list of objects whose properties include a DateTime value. I’d like to display, and allow editing the Date and Time components in separate columns. How would I do this?

Answer 1

Here’s how I’d do it.

Make your property that exposes the DateTime (together) invisible in the DataGridView.

Have two other properties, Date and Time and have these properties essentially link back to your DateTime property.

Like this:

[Browsable(false)]
public DateTime DateTime { get; set; }

public DateTime Date
{
    get { return this.DateTime.Date; }
    set
    {
        TimeSpan time = this.Time;
        this.DateTime = value.Date + time;
    }
}

public TimeSpan Time
{
    get { return this.DateTime.TimeOfDay; }
    set
    {
        this.DateTime = this.Date + value;
    }
}
