如何从Tablecell ASP.NET检索数据 [英] How to retrieve data from tablecell ASP.NET

问题描述

当我加载页面时，我发送表将具有的行数：

When I load the page I send the number of rows the table will have:

protected void Page_Load(object sender, EventArgs e)
{
    string numFilas = Request.QueryString["filas"];
    tblAdd.Visible = true;
    for (int i = 0; i < int.Parse(numFilas); i++)
    {
        TableRow NewRow1 = new TableRow();
        TableCell NewCell1 = new TableCell();
        TableCell NewCell2 = new TableCell();

        TextBox txtBox1 = new TextBox();
        txtBox1.Width = 200;
        TextBox txtBox2 = new TextBox();
        txtBox2.Width = 200;
        // adding lebel into cell
        NewCell1.Controls.Add(txtBox1);
        NewCell2.Controls.Add(txtBox2);
        // adding cells to row
        NewRow1.Cells.Add(NewCell1);
        NewRow1.Cells.Add(NewCell2);

        tblAdd.Rows.Add(NewRow1);
    }
}

现在，当我单击提交时，我想检索表格中文本框的数据，我能做到的是：

now when I click submit I'd like to retrieve the data of the textbox inside the table, what I've been capable of is this:

  public void submit(Object sender, EventArgs e)
{
    for (Int32 i = 0; i < tblAdd.Rows.Count; i++)
    {
        TableRow dr = tblAdd.Rows[i];
        TableCell hhh = dr.Cells[0];
        String textCell = hhh.Text();

    }
}

但是，单元格中的文本为空，因为用户写的文本在文本框中，我不知道该怎么获得。

However, the text in the cells is empty because the text the user writes is IN the textbox, which I don't know how to get it.

推荐答案

尝试这

1. 在创建文本框时添加ID

例如

txtBox1.ID = "txtBox1";

1. 然后您可以轻松找到它来自当前单元格控件集合的TextBox控件如下。

1. Then you can easily find this TextBox control from the current Cell's Controls collection as follows.

string textCell =（（TextBox）dr.Cells [0] .FindControl（ txtBox1））。Text;

string textCell = ((TextBox)dr.Cells[0].FindControl("txtBox1")).Text;

希望您能理解我的意思。基本上，您需要在单元格中找到控件。

Hope you understood what I'm trying to say. Basically, you need to find your control in the Cell.
