asp.net2.0 - web自定义控件的智能标记问题
这两天写了个web自定义控件，控件由一个TextBox、一个Button、一个Calendar构成。但不知道怎么给加个智能标记，智能标记是用来选择Calendar样式的。希望得到指点，谢谢！
下面是控件代码：
[Designer(typeof(DateSelectDesignerActionList))]
[DefaultProperty( "EnableMultiSelect ")]
[ToolboxBitmap(typeof(DateTextBox), "ToolIcon.DateSelect.bmp ")]
[ToolboxData( " <{0}:DateSelect runat=server> </{0}:DateSelect> ")]
public class DateSelect : WebControl, INamingContainer, IComponent
{
private TextBox txtDateTime;
private Button btnSelect;
private Calendar calDateTime;
public DateSelect()
{
InitializeComponent();
}
public void InitializeComponent()
{
CreateComponent();
SetComponentProperty();
SetComponentEvent();
}
public void CreateComponent()
{
// Create Control
txtDateTime = new TextBox();
btnSelect = new Button();
calDateTime = new Calendar();
// Nest Control
Controls.Add(txtDateTime);
Controls.Add(btnSelect);
Controls.Add(calDateTime);
}
public void SetComponentProperty()
{
btnSelect.Text = "选择 ";
calDateTime.Visible = false;
calDateTime.Font.Name = "Verdana ";
calDateTime.Font.Size = 8;
calDateTime.Style.Add( "position ", "absolute ");
calDateTime.Style[ "top "] = txtDateTime.Style[ "top "];
calDateTime.Style[ "left "] = txtDateTime.Style[ "left "];
}
public void SetComponentEvent()
{
btnSelect.Click += new EventHandler(btnSelect_Click);
calDateTime.SelectionChanged += new EventHandler(calDateTime_SelectionChanged);
calDateTime.Load += new EventHandler(calDateTime_Load);
}
public void btnSelect_Click(object sender, EventArgs e)
{
if (EnableMultiSelect)
{
if (btnSelect.Text == "选择 ")
{
btnSelect.Text = "完成 ";
calDateTime.Visible = true;
}
else
{
btnSelect.Text = "选择 ";
calDateTime.Visible = false; ;
}
}
else
{
calDateTime.Visible = true; ;
}
}
public void calDateTime_SelectionChanged(object sender, EventArgs e)
{
string selectedDates = txtDateTime.Text;
if (EnableMultiSelect)
{
string s = string.Empty;
SelectedDatesCollection sdc = calDateTime.SelectedDates;
foreach (DateTime dt in sdc)
{
s = dt.ToString( "yyyy-MM-dd ");
if (selectedDates.IndexOf(s) == -1)
{
selectedDates += ", " + s;
calDateTime.SelectedDates.Add(Convert.ToDateTime(s));
}
//else
//{
//int i = selectedDates.IndexOf(s);
//selectedDates = selectedDates.Remove(i, i + s.Length);
//calDateTime.SelectedDates.Remove(Convert.ToDateTime(s));
//}
}
selectedDates = selectedDates.Trim( ', ');
}
else
{
selectedDates = calDateTime.SelectedDate.ToString( "yyyy-MM-dd ");
calDateTime.Visible = false;
}
Text = selectedDates;
txtDateTime.Text = selectedDates;
}
public void calDateTime_Load(object sender, EventArgs e)
{
if (Text != string.Empty)
{
string[] selectedDates = Text.Split( ', ');
foreach (string s in selectedDates)
{
calDateTime.SelectedDates.Add(Convert.ToDateTime(s));
}
}
}

#region TextBox BackColor
public override Color BackColor

protected override void RenderContents(HtmlTextWriter output)
{
txtDateTime.RenderControl(output);
btnSelect.RenderControl(output);
calDateTime.RenderControl(output);
}
}
智能标记代码，存在问题，有点迷糊了：
using System;
using System.ComponentModel.Design;
public class DateSelectDesignerActionList : DesignerActionList
{
public DateSelectDesignerActionList(DateSelect ds)
: base(ds)
{
AutoShow = true;
}
public override DesignerActionItemCollection GetSortedActionItems()
{
DesignerActionItemCollection actionItems = new DesignerActionItemCollection();
actionItems.Add(
new DesignerActionMethodItem(this, "自动套用格式 ", "Calendar 任务 ", true)
);
return actionItems;
}
}
