当写好一个自定义控件，在页面上注册好后再页面上添加一个试试，能正常看到效果，然而当执行这个页面的时候报错，未知的服务器标记，在网上查了查，原来还得在web.config中加上一段话
自定义控件
代码 namespace PureTest
{
[ToolboxData("<{0}:Pager runat=server></{0}:Pager>")]
public class Pager:Control
{
public int CurrentPage
{
get; set;
}
public int PageSize
{
get; set;
}
public int TotalCount
{
get; set;
}
//hack:这里应该把分页时的URL条件带上
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
//var first = CurrentPage - 5;
//var end = CurrentPage + 5;
//var totalPage = GetPageCount();
//if (first < 1)
//{
// first = 1;
//}
//if (end > totalPage)
//{
// end = totalPage;
//}
//var sb = new StringBuilder();
//sb.Append("<div id='pager'>");
//for(var i=first;i<end;i++)
//{
// if(i==CurrentPage)
// {
// sb.AppendFormat("<strong>{0}</strong>", i);
// }
// else
// {
// sb.AppendFormat("<a href='{0}.html'>{0}</a>", i);
// }
//}
//sb.Append("</div>");
//writer.Write(sb.ToString());
writer.Write("my first control");
}
private int GetPageCount()
{
return PageSize == 0 ? 0 : (TotalCount + PageSize - 1)/PageSize;
}
}
}
