我在页面上选择类型后修改页面ext:label的text值，然后我在后台再取该text，下面红色部分显示出来的值还是原来的值，有知道的告诉下 ，谢谢！

先赋值：

List listLab = Ext.Net.Utilities.ControlUtils.FindControls(this.Page);

List listNum = Ext.Net.Utilities.ControlUtils.FindControls(this.Page);

for (var i = 0; i < dt.Rows.Count; i++)

{

var labid = "rate" + i.ToString() + "_lab";

var numid = "money" + i.ToString() + "_lab";

listLab.Find(p => p.ID == labid).Text = dt.Rows[i][rate].ToString();

listNum.Find(p => p.ID == numid).TabTip = dt.Rows[i]["b_id"].ToString();

}

再取值：

List listNum = Ext.Net.Utilities.ControlUtils.FindControls(this.Page);

List listLab = Ext.Net.Utilities.ControlUtils.FindControls(this.Page);

List valList = new List();

List noList = new List();

var i = 0;

foreach (Ext.Net.NumberField field in listNum)

{

string v = field.Text.Trim();

if (!string.IsNullOrEmpty(v))

{

if (isCheckMinValue(v))

valList.Add(listLab[i].TabTip + "," +listLab[i].Text.Trim()+ "," + v + "," + field.TabTip);

else

noList.Add(listLab[i].TabTip + "," + listLab[i].Text.Trim() + "," + v + field.TabTip);

}

i++;

}
