Using the SharePoint date control in a web part

After a lot of requests in comments in this blog, I figured this must be very hard to implement. So I tried, and found it quite easy. Here is a code sample of a web part that uses the sharepoint date control

The code is simple - three controls - a DateTimeControl from the Microsoft.SharePoint.WebControls namespace, a button and a text box.
The button has a click event. On click, the event sets the text box to display the date that was selected in the DateTimeControl.


public class DatePickerWebPart : System.Web.UI.WebControls.WebParts.WebPart {
DateTimeControl dtc;
TextBox t;
Button b;

protected override void CreateChildControls()
{
base.CreateChildControls();
dtc = new DateTimeControl();
dtc.ID = "dtc" + this.UniqueID;
this.Controls.Add(dtc);
b = new Button();
b.Text = "Click me to see the date";
this.Controls.Add(b);
b.Click += new EventHandler(b_Click);
t = new TextBox();
this.Controls.Add(t);
}

void b_Click(object sender, EventArgs e)
{
t.Text = dtc.SelectedDate.ToLongDateString();
}
}

Here is the result:

This is the web part when the page first loads


This is the web part when you click on the date picker
