看到dudu关于递归控件的方法，想起以前实现过的递归控件以加入JS来将用户的动作写入日志：
private void SetCtlClentProperty(String sSecID,Control ctrl)
{ 
if(ctrl!=null)
{ foreach (Control obj in ctrl.Controls) { if (obj.GetType().ToString() == "System.Web.UI.WebControls.TextBox") ((TextBox)obj).Attributes["onchange"] += "SetPageDataStatus();SetCtrlStatus('"+sSecID+"');"; if (obj.GetType().ToString() == "System.Web.UI.WebControls.Label") ((Label)obj).Attributes["onchange"] += "SetPageDataStatus();SetCtrlStatus('"+sSecID+"');"; if (obj.GetType().ToString() == "System.Web.UI.WebControls.DropDownList" && ((DropDownList)obj).AutoPostBack==false) ((DropDownList)obj).Attributes["onchange"] += "SetPageDataStatus();SetCtrlStatus('"+sSecID+"');"; if (obj.GetType().ToString() == "System.Web.UI.WebControls.DropDownList" && ((DropDownList)obj).AutoPostBack==true) ((DropDownList)obj).Attributes["onchange"] += "SetPageDataStatus();SetCtrlStatus('"+sSecID+"');__doPostBack('"+((DropDownList)obj).ClientID+"','');"; if ((obj.GetType().ToString() == "System.Web.UI.WebControls.CheckBoxList" || obj.GetType().ToString() == "System.Web.UI.WebControls.RadioButtonList" ) && ((CheckBoxList)obj).AutoPostBack==true) { for(int k=0;k<((CheckBoxList)obj).Controls.Count;k++) { ((CheckBox)((CheckBoxList)obj).Controls[0]).Attributes["onclick"] += "SetPageDataStatus();SetCtrlStatus('"+sSecID+"');__doPostBack('"+((CheckBox)((CheckBoxList)obj).Controls[0]).ClientID+"','');";
} } if((obj.GetType().ToString() == "System.Web.UI.WebControls.CheckBoxList" || obj.GetType().ToString() == "System.Web.UI.WebControls.RadioButtonList" ) && ((CheckBoxList)obj).AutoPostBack==false) ((CheckBox)((CheckBoxList)obj).Controls[0]).Attributes["onclick"] += "SetPageDataStatus();SetCtrlStatus('"+sSecID+"');"; SetCtlClentProperty(sSecID,obj); } }
} /**/ /// <summary> /// Set Control's onchange event; /// </summary> /// <param name="oPage">Page object</param> /// <param name="sCtrlIDs">section ids seperated with ",", like "section1,section2,section3"</param> private void SetCtlClentProperty(ArrayList oCtrlIDs) { foreach (Control oSecID in oCtrlIDs) { if (oSecID == null) continue; if (this._ThisPage.IsPostBack) { this._ThisPage.RegisterHiddenField(oSecID.ID,System.Web.HttpContext.Current.Request.Form[oSecID.ID]); } else { this._ThisPage.RegisterHiddenField(oSecID.ID,"unchanged"); } SetCtlClentProperty(oSecID.ID,oSecID); } } private void SetCtlClentProperty(ArrayList oCtrlIDs, bool ClearState) { foreach (Control oSecID in oCtrlIDs) { if (oSecID == null) continue; if (this._ThisPage.IsPostBack && !ClearState) { this._ThisPage.RegisterHiddenField(oSecID.ID,System.Web.HttpContext.Current.Request.Form[oSecID.ID]); } else { this._ThisPage.RegisterHiddenField(oSecID.ID,"unchanged"); } SetCtlClentProperty(oSecID.ID,oSecID); } }
