Question

c#如何获取repeater中某一行某一列文本框的值 文本框没有id

文本框是由repeater循环出来的，所以id不确定，每行有三个文本框。 我想for循环遍历repeater中的文本框中的值。求大神帮解答。 主要要代码

//后台获取
 protected void btnPay_Click(object sender, EventArgs e)
    {
        if (rptMest.Items.Count > 0)
        {

            List<Model.Pay> listPayModel = new List<Model.Pay>();
            foreach (RepeaterItem rptitem in this.rptMest.Items)
            {
                payModel = new Model.Pay();
                HiddenField hfID = (HiddenField)rptitem.FindControl("hfID");
                Label lblFee = rptitem.FindControl("lblFee") as Label;
                TextBox txtPayment = rptitem.FindControl("txtPayment") as TextBox;
                TextBox txtNotes = rptitem.FindControl("txtNotes") as TextBox;
                TextBox txtPayDate = rptitem.FindControl("txtPayDate") as TextBox;
                payModel.OperatingDate = Convert.ToDateTime(txtPayDate.Text);
                payModel.Fee = Convert.ToInt32(lblFee.Text);
                payModel.ManifestID = hfID.Value;
                payModel.CreateUser = CurrentUser.ID;
                payModel.OperatingUser = CurrentUser.ID;
                payModel.Remark = "";
                payModel.Payment = Convert.ToInt32(txtPayment.Text);
                listPayModel.Add(payModel);
            }
            if (payBLL.Add(listPayModel))
            {
                Common.MessageBox.Show(this.Page, "付款处理成功！");
                InitData();
                DataBinds();
            }
            else
            {
                Common.MessageBox.Show(this.Page, "付款处理失败！");
                DataBinds();
            }
        }
    }

Answer 2

protected void rMain_ItemCommand(object source, RepeaterCommandEventArgs e)
{
ImageButton ib = e.Item.FindControl("img") as ImageButton;
int cid = int.Parse(e.CommandArgument.ToString());
if (null != ib)
{
Panel p = e.Item.FindControl("pMain") as Panel;
if (ib.ImageUrl == "~/Images/Up.gif")
{
ib.ImageUrl = "~/Images/Down.gif";
p.Visible = false;

}
else
{
ib.ImageUrl = "~/Images/Up.gif";

p.Visible = true;
IList<PlaneTypeInfo> types = new PlaneTypeDAL().GetAllPlaneTypesByCid(cid);
GridView g = e.Item.FindControl("gvMain") as GridView;
g.DataSource = types;
g.DataBind();
}
}
}
只要在ItemCommand和ItemDataBound事件中，都可以通过e.Item.FindControl("控件的id")来查找控件.
