ViewManager里面事实上是存在有一个BUG.如果控件存在着LinkButton,GridView等的必须依赖Form存在的控件,就会出现报错现象!
我的解决方法是
/// <summary>
/// 解释控件HTML
/// </summary>
/// <param name="control"></param>
/// <returns></returns>
public string RenderView(T control)
{
try
{
HtmlForm _form = new HtmlForm();
_form.ID = "form1";
_form.EnableViewState = false;
_pageHolder.Controls.Add(_form);
HtmlGenericControl _ulControl = new HtmlGenericControl("UL");
_form.Controls.Add(_ulControl);
_ulControl.Controls.Add(control);
System.IO.StringWriter output = new System.IO.StringWriter();
System.Web.HttpContext.Current.Server.Execute(_pageHolder, output, false);
System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
xmlDoc.LoadXml(output.ToString());
_pageHolder.Controls.Clear();
output.Close();
_form.Dispose();
return xmlDoc.DocumentElement.SelectNodes("UL")[0].InnerXml;
}
catch { return string.Empty; }
}
至于为什么要用XmlDocument读取指定的HTML模板,就是要去除生成出来多余的HTML代码
