如何自定义属性添加到自定义三夏 [英] How to add custom properties to a custom webcontrol

问题描述

我想自定义类型属性添加到夏精，例如像EditRowStyle在GridView的，但在某种程度上，房地产的属性可以在ASCX / ASPX源视图中声明。很明显，GridView控件还没有得到像EditRowStyle，背景色的属性，但只有EditRowStyle了。事情是这样的：

 公共类MyCustomGrid：GridView控件
{
  [...]
  私人MyCustomSettings customSettings;
  公共MyCustomSettings CustomSettings
        {
            {返回customSettings; }
        }
  [...]
}

公共类MyCustomSettings
{
  私人字符串的CssClass =默认;
  公共字符串的CssClass
  {
    {返回的CssClass; }
    集合{的CssClass =价值; }
  }
}
 

和电网decalartion：

 ＆LT; C1：MyCustomGrid ID =grdCustom=服务器CustomSettings-的CssClass =customcss/＆GT;
 

由于该解决方案是行不通的。

解决方案

 公共类MyCustomGrid：GridView控件
{
  [...]
  私人MyCustomSettings customSettings;
  [PersistenceMode(PersistenceMode.InnerProperty),DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
  公共MyCustomSettings CustomSettings
        {
            {返回customSettings; }
        }
  [...]
}

[类型转换器（typeof运算（MyCustomSettings））]
公共类MyCustomSettings
{
  私人字符串的CssClass =默认;
  公共字符串的CssClass
  {
    {返回的CssClass; }
    集合{的CssClass =价值; }
  }
}
 

I want to add custom typed properties to a webcontrol, like for example EditRowStyle in GridView, but in a way that the property's properties can be declared in Source view in ascx/aspx. It's clear that GridView hasn't got a property like EditRowStyle-BackColor, but only EditRowStyle has. Something like this:

public class MyCustomGrid : GridView
{
  [...]
  private MyCustomSettings customSettings;
  public MyCustomSettings CustomSettings
        {
            get { return customSettings; }
        }
  [...]
}

public class MyCustomSettings 
{
  private string cssClass = "default";
  public string CssClass
  {
    get { return cssClass; }
    set { cssClass = value; }
  }
}

And the grid decalartion:

<c1:MyCustomGrid ID="grdCustom" runat="server" CustomSettings-CssClass="customcss" />

Because this solution doesn't work.

解决方案

public class MyCustomGrid : GridView
{
  [...]
  private MyCustomSettings customSettings;
  [PersistenceMode(PersistenceMode.InnerProperty),DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
  public MyCustomSettings CustomSettings
        {
            get { return customSettings; }
        }
  [...]
}

[TypeConverter(typeof(MyCustomSettings))]
public class MyCustomSettings 
{
  private string cssClass = "default";
  public string CssClass
  {
    get { return cssClass; }
    set { cssClass = value; }
  }
}
