如何遍历Table控件中动态创建的ROW 和CELL，并判断每个CELL中的控件类型！！！！

[jasonM2008]

我是这样做的，但是怎么只得到了一个控件，但是我页面上不只一个！动态创建了很多个控件！
foreach(TableRow TR in tbContent.Rows)
foreach (TableCell TD in TR.Cells)
foreach (Control ctl in TD.Controls)
{
Response.Write(ctl.GetType().ToString());
}
得到这个：System.Web.UI.WebControls.Button

动态创建控件的代码如下：

if (!IsPostBack)
        {
            MyInit();
            int nExam_Id = int.Parse(Request.QueryString["ExamId"].ToString());
            string strSQL = "select * from Online_Exam where Exam_Id = '" + nExam_Id.ToString() + "'";
            DataSet ds = DataOpera.QueryData(strSQL);
            if (ds.Tables[0].Rows.Count > 0)
            {
                lb_Tittle.InnerText = ds.Tables[0].Rows[0]["Tittle"].ToString();
                spAuthor.InnerText = ds.Tables[0].Rows[0]["Exam_Author"].ToString();
                spDate.InnerText = ds.Tables[0].Rows[0]["Exam_Date"].ToString();
                spTime.InnerText = ds.Tables[0].Rows[0]["Time"].ToString();
                spId.InnerText = ds.Tables[0].Rows[0]["Exam_Id"].ToString();
                ds.Clear();
            }
            strSQL = "select * from Exam_Subject where Exam_Id =" + nExam_Id.ToString() + " order by Subject_Num asc , Sub_Num asc";
            ds = DataOpera.QueryData(strSQL);
            int nCount = ds.Tables[0].Rows.Count;
            nRecordCount = nCount;
            if (nCount > 0)
            {
                int nID = 0;
                for (int nIndex = 0; nIndex < nCount; nIndex++)
                {
                    nID = int.Parse(ds.Tables[0].Rows[nIndex]["ID"].ToString());
                    switch (int.Parse(ds.Tables[0].Rows[nIndex]["Subject_Type"].ToString()))
                    {
                        case 1:
                            AddSingleOption(ds, nID);
                            break;
                        case 2:
                            AddMultiOption(ds, nID);
                            break;
                        case 3:
                            AddInput(ds, nID);
                            break;
                        case 4:
                            Addjuge(ds, nID);
                            break;
                        case 5:
                            AddAnswer(ds, nID);
                            break;
                        case 6:
                            AddDesign(ds, nID);
                            break;
                        default:
                            break;
                    }

                }

            }

        }
        AddSubmitButton();
    }

public void AddInput(DataSet ds, int nIndex) //增加填空题
    {
        if (bFirstInput)
        {
            TableRow tbRow = new TableRow();
            TableCell tbCell = new TableCell();
            Label lbTittleHead = new Label();
            lbTittleHead.ID = "lbTittleHead" + nIndex.ToString();
            lbTittleHead.Text = "填空题";
            tbCell.Controls.Add(lbTittleHead);
            tbCell.CssClass = "InputHead";
            tbCell.ColumnSpan = 2;
            tbRow.Cells.Add(tbCell);
            tbContent.Rows.Add(tbRow); //添加一行到表格中
            bFirstInput = false;
        }
        string strTittle;
        strTittle = "<xmp>" + ds.Tables[0].Rows[nIndex]["Subject_Tittle"].ToString() + "</xmp>"; //填空描述

        //放置一行放置标题
        TableRow tbRowTittle = new TableRow();
        TableCell tbCellTittle = new TableCell(); //放置标题
        Label lbTittle = new Label();
        nInputCount++;
        lbTittle.Text = "(" + nInputCount.ToString() + ")," + strTittle;
        lbTittle.ID = "lbTittle" + nIndex.ToString(); //记录的ID是LABEL的ID
        tbCellTittle.CssClass = "InputTittle";
        tbCellTittle.ColumnSpan = 2;
        tbCellTittle.Controls.Add(lbTittle);
        tbRowTittle.Cells.Add(tbCellTittle); //添加一个单元格
        tbContent.Rows.Add(tbRowTittle); //添加到表格中


        //添加一行用于放置textbox 让用户输入
        TableRow tbRowInput = new TableRow();
        TableCell tbCellInput = new TableCell();
        TextBox txtInput = new TextBox();
        txtInput.CssClass = "Exam_txtBox";
        txtInput.ID = "txtInput" + nIndex.ToString();
        txtInput.TextMode = TextBoxMode.MultiLine;
        tbCellInput.CssClass = "Input";
        tbCellInput.ColumnSpan = 2;
        tbCellInput.Controls.Add(txtInput);
        tbRowInput.Cells.Add(tbCellInput);
        tbContent.Rows.Add(tbRowInput); //添加到表格中

    }
。。。。。。。。

各位帮我看看！！！！改怎么来做到这点！！！！
谢谢，我新手！说详细点！

public static void SetControlEnabled(Control parent,bool strBool)
{
if (parent == null)
{
return;
}

foreach(Control webControl in parent.Controls)
{
string controlType=webControl.GetType().FullName;
switch (controlType)
{
case "System.Web.UI.WebControls.TextBox":
((System.Web.UI.WebControls.TextBox)webControl).Enabled=strBool;
break;
case "System.Web.UI.WebControls.Button":
((System.Web.UI.WebControls.Button)webControl).Enabled=strBool;
break;
case "System.Web.UI.WebControls.ListBox":
((System.Web.UI.WebControls.ListBox)webControl).Enabled=strBool;
break;
case "System.Web.UI.WebControls.Label":

}

if (webControl.Controls.Count > 0)
{
SetControlEnabled(webControl,strBool);
}
}

得用到递归遍历.

汗，这么长的代码，纯体力活~~^^!
