在设计主机中更新innerproperties样式类 [英] Update innerproperties style class in design host
问题描述
你好
我正在创建一个自定义菜单脚本控件，我在设计主机中遇到了我的设计器类的问题。我刚刚开始创建我的控件，所以我没有太多，但我确实添加了一些属性并构建了一个设计器，因此我的属性可以在设计时更新。
要添加我控制的样式我添加了2个样式作为内部属性我还创建了一个Test属性，以便在我更改智能任务时查看它是否在设计主机中更新。 Test属性会像它应该更新，但内部属性不是这样，我必须遗漏一些东西。
这就是我得到的。
HTML页面
Hello
I'm creating a custom Menu scriptcontrol and I'm facing a problem in the design host with the my designer class. I just started creating my control so I don't have much but I did add some properties and building a designer so my properties can be updated in designtime.
To add styles to my control I have added 2 styles as an innerproperty also I made a Test property to see if it gets updated in the design host when I change in my Smart Task. The Test property gets updated like it should but the innerproperties not so I must be missing something.
This is what I got.
the HTML page
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager runat="server" ID="Scriptmanager1"></asp:ScriptManager>
<nav>
<quyodev:WebMenu runat="server" ID="MenuTest" Testen="">
<StaticMenuStyle CssClass="Test" BackColor="Blue" Width="600px" Height="30px" />
<StaticMenuHoverStyle BackColor="Yellow" Width="600px" Height="30px" />
</quyodev:WebMenu>
</nav>
</form>
</body>
</html>
我遇到问题的部分属性。
这些属性未在设计主机中更新。
Part of the properties which I'm having problems with.
those properties are not updated in the design host.
[PersistenceMode(PersistenceMode.InnerProperty)]
public Style StaticMenuStyle
{
get
{
if (_staticMenuStyle == null)
{
_staticMenuStyle = new Style();
if (IsTrackingViewState)
((IStateManager)_staticMenuStyle).TrackViewState();
}
return _staticMenuStyle;
}
}
[PersistenceMode(PersistenceMode.InnerProperty)]
public Style StaticMenuHoverStyle
{
get
{
if (_staticMenuHoverStyle == null)
{
_staticMenuHoverStyle = new Style();
if (IsTrackingViewState)
((IStateManager)_staticMenuHoverStyle).TrackViewState();
}
return _staticMenuHoverStyle;
}
}
这是我的设计师课程。
Here is my designer class.

using System.Linq;

using System.Web.UI.Design;
using System.Web.UI.WebControls;
namespace QuyoDev.Web.UI.Design.WebControls
{
internal class WebMenuDesigner : ControlDesigner
{
private WebMenu _control;
private ViewTypes _view;
public override void Initialize(IComponent component)
{
base.Initialize(component);
_control = (WebMenu)component;
}
public ViewTypes View
{
get { return _view; }
set { _view = value; }
}
public Style SelectedStyle
{
get { return (Style)TypeDescriptor.GetProperties(_control)[string.Format("{0}Style", View)].GetValue(_control); }
set { TypeDescriptor.GetProperties(_control)[string.Format("{0}Style", View)].SetValue(_control, value); UpdateDesignTimeHtml(); }
}
public override DesignerActionListCollection ActionLists
{

{
DesignerActionListCollection actionLists = new DesignerActionListCollection();
actionLists.AddRange(base.ActionLists);
actionLists.Add(new ActionList(this));
return actionLists;
}
}
public override string GetDesignTimeHtml()
{
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
htmlWriter.AddAttribute(HtmlTextWriterAttribute.Class, SelectedStyle.CssClass);
htmlWriter.AddAttribute(HtmlTextWriterAttribute.Style, SelectedStyle.GetStyleAttributes(null).Value);
htmlWriter.RenderBeginTag(HtmlTextWriterTag.Div);
//ChildItems
htmlWriter.RenderEndTag();
return stringWriter.ToString();
}
public enum ViewTypes

}
private class ActionList : DesignerActionList
{
private WebMenuDesigner _parent;
public ActionList(WebMenuDesigner parent) : base(parent.Component)
{
_parent = parent;
}
public ViewTypes View
{
get { return _parent.View; }
set
{
_parent.View = value;
_parent.UpdateDesignTimeHtml();
}
}
public string CssClass
{
get { return TypeDescriptor.GetProperties(_parent.SelectedStyle)["CssClass"].GetValue(_parent.SelectedStyle).ToString(); }
set
{
TypeDescriptor.GetProperties(_parent.SelectedStyle)["CssClass"].SetValue(_parent.SelectedStyle, value);
_parent.UpdateDesignTimeHtml();
}
}
public Color BackColor
{
get { return (Color)TypeDescriptor.GetProperties(_parent.SelectedStyle)["BackColor"].GetValue(_parent.SelectedStyle); }
set
{
TypeDescriptor.GetProperties(_parent.SelectedStyle)["BackColor"].SetValue(_parent.SelectedStyle, value);
_parent.UpdateDesignTimeHtml();
}
}
public string TestAction
{
get { return TypeDescriptor.GetProperties(_parent.Component)["Testen"].GetValue(_parent.Component).ToString(); }
set { TypeDescriptor.GetProperties(_parent.Component)["Testen"].SetValue(_parent.Component, value); }
}
public override DesignerActionItemCollection GetSortedActionItems()
{
DesignerActionItemCollection items = new DesignerActionItemCollection();
items.Add(new DesignerActionHeaderItem("Appearance"));
items.Add(new DesignerActionPropertyItem("View", "View:", "Appearance", "Change webmenu display"));
items.Add(new DesignerActionPropertyItem("TestAction", "Test:", "Appearance", "Do Test"));
items.Add(new DesignerActionHeaderItem("Style"));
items.Add(new DesignerActionPropertyItem("CssClass", "CssClass:", "Style", "Change CSS class"));
items.Add(new DesignerActionPropertyItem("BackColor", "BackColor:", "Style", "Change background color"));
return items;
}
}
}
}
我尝试了什么：
创建一个Test属性，看看它是否在设计主机中得到更新，但这很有效。
What I have tried:
Created a Test property to see if this gets updated in the design Host but this works perfect.
推荐答案
我能够通过添加底层代码来解决我的解决方案
I was able to resolve my solution with adding underlaying code
public void UpdateSelectedStyle(string property, object value)
{
Style style = new Style();
style.CopyFrom(SelectedStyle);
TypeDescriptor.GetProperties(style)[property].SetValue(style, value);
SelectedStyle = style;
UpdateDesignTimeHtml();
}
