This is what I use.
namespace ControlLibrary
{
public partial class DatePicker : BaseControl
{
public String _Heading
{
get
{
return label1.Text;
}
set
{
label1.Text = (value ?? string.Empty).ToString();
}
}
public String _Text { get; set; }
public Boolean _Queued { get; set; }
public Gizmox.WebGUI.Forms.DateTimePicker dateTimePicker1 { get; set; }
public DatePicker()
{
InitializeComponent();
_Queued = true;
}
void splitContainer1_Resize(object sender, EventArgs e)
{
splitContainer1.SplitterDistance = (splitContainer1.Size.Width / 2) - 1;
splitContainer1.Panel1.Update();
splitContainer1.Panel2.Update();
}
public override BaseControl Initialize(BaseControl Parent)
{
base.BaseInitialize(Parent, this);
splitContainer1.SplitterDistance = (splitContainer1.Size.Width / 2) - 1;
splitContainer1.Panel1.Update();
splitContainer1.Panel2.Update();
splitContainer1.Resize += new EventHandler(splitContainer1_Resize);
if (_ColumnValue == null)
_ColumnValue = Null.NullDate;
if ((DateTime)_ColumnValue != null
&& (DateTime)_ColumnValue > Null.NullDate)
{
this.splitContainer1.Panel2.Controls.Clear();
dateTimePicker1 = new DateTimePicker();
dateTimePicker1.Size = textBox1.Size;
dateTimePicker1.Dock = DockStyle.Fill;
dateTimePicker1.Value = (DateTime)_ColumnValue;
dateTimePicker1.Format = DateTimePickerFormat.Short;
if (_Queued)
dateTimePicker1.ValueChangedQueued += new EventHandler(dp_ValueChangedQueued);
else
dateTimePicker1.ValueChanged += new EventHandler(dp_ValueChanged);
_Text = dateTimePicker1.Value.ToShortDateString();
splitContainer1.Panel2.Controls.Add(dateTimePicker1);
}
else
{
textBox1.Click += new EventHandler(textBox1_Click);
textBox1.TextChanged +=new EventHandler(textBox1_TextChanged);
}
return this;
}
void textBox1_TextChanged(object sender, EventArgs e)
{
if (dateTimePicker1 == null)
{
_ColumnValue = DateTime.Now;
this.splitContainer1.Panel2.Controls.Clear();
dateTimePicker1 = new DateTimePicker();
dateTimePicker1.Size = textBox1.Size;
dateTimePicker1.Dock = DockStyle.Fill;
dateTimePicker1.Value = (DateTime)_ColumnValue;
dateTimePicker1.Format = DateTimePickerFormat.Short;
if (_Queued)
dateTimePicker1.ValueChangedQueued += new EventHandler(dp_ValueChangedQueued);
else
dateTimePicker1.ValueChanged += new EventHandler(dp_ValueChanged);
splitContainer1.Panel2.Controls.Add(dateTimePicker1);
_Text = dateTimePicker1.Value.ToShortDateString();
Text = DateTime.Now.ToLongTimeString();
}
}
void textBox1_Click(object sender, EventArgs e)
{
if (dateTimePicker1 == null)
{
_ColumnValue = DateTime.Now;
this.splitContainer1.Panel2.Controls.Clear();
dateTimePicker1 = new DateTimePicker();
dateTimePicker1.Size = textBox1.Size;
dateTimePicker1.Dock = DockStyle.Fill;
dateTimePicker1.Value = (DateTime)_ColumnValue;
dateTimePicker1.Format = DateTimePickerFormat.Short;
if (_Queued)
dateTimePicker1.ValueChangedQueued += new EventHandler(dp_ValueChangedQueued);
else
dateTimePicker1.ValueChanged += new EventHandler(dp_ValueChanged);
splitContainer1.Panel2.Controls.Add(dateTimePicker1);
_Text = dateTimePicker1.Value.ToShortDateString();
Text = DateTime.Now.ToLongTimeString();
}
}
void dp_ValueChanged(object sender, EventArgs e)
{
try
{
_ColumnValue = dateTimePicker1.Value;
_Text = dateTimePicker1.Value.ToShortDateString();
Text = DateTime.Now.ToLongTimeString();
}
catch { }
}
void dp_ValueChangedQueued(object sender, EventArgs e)
{
try
{
_ColumnValue = dateTimePicker1.Value;
_Text = dateTimePicker1.Value.ToShortDateString();
Text = DateTime.Now.ToLongTimeString();
}
catch { }
}
}
}
You'll have to strip out the basecontrol stuff, but if the _ColumnValue is null an empty textbox is displayed, as soon as the user clicks in the textbox it is replaced with a datetime picker set to the current date.
Hope this helps,
