删除动态创建的控件

Question

我试图在C#2008 asp.net中删除动态创建的控件

控件在此处创建:

        int i;
        for (i = 0; i < myCount; i += 1)
        {
            TextBox txtAuto = new TextBox();
            TextBox txtModel = new TextBox();
            TextBox txtMiles = new TextBox();
            TextBox txtVINumber = new TextBox();
            TextBox txtPlateNumber = new TextBox();

            txtAuto.ID = "txtVehAuto" + i.ToString();
            txtModel.ID = "txtVehModel" + i.ToString();
            txtMiles.ID = "txtVehMilage" + i.ToString();
            txtVINumber.ID = "txtVehVINumber" + i.ToString();
            txtPlateNumber.ID = "txtVehPlate" + i.ToString();

            phAuto.Controls.Add(txtAuto);
            phModel.Controls.Add(txtModel);
            phMiles.Controls.Add(txtMiles);
            phVINumber.Controls.Add(txtVINumber);
            phPlateNumber.Controls.Add(txtPlateNumber);

            dyntxtAuto[i] = txtAuto;
            dyntxtModel[i] = txtModel;
            dyntxtMiles[i] = txtMiles;
            dyntxtVINumber[i] = txtVINumber;
            dyntxtPlateNumber[i] = txtPlateNumber;

            LiteralControl literalBreak = new LiteralControl("<br />");

            phAuto.Controls.Add(literalBreak);
            phModel.Controls.Add(literalBreak);
            phMiles.Controls.Add(literalBreak);
            phVINumber.Controls.Add(literalBreak);
            phPlateNumber.Controls.Add(literalBreak);
        }
    }

如何删除控件？用户将单击"提交",此时用户输入的数据将被写入数据库.页面将返回自身(带有空白字段).我想在将数据写入数据库后删除动态控件.删除意义删除,而不是隐藏.我试图将ViewState设置为false,但它没有帮助.

你能做这个吗？

phAuto.Controls.Clear();
phModel.Controls.Clear();
phMiles.Controls.Clear();
phVINumber.Controls.Clear();
phPlateNumber.Controls.Clear();

这些控件中是否有其他控件我不知道您不想清除？
