我要做的是选择日期第一个文本框。例如2013年6月14日，生成显示的网格视图，其中包含5个日期（其他日期将根据文本框中的选定日期计算）。在gridview下方有一个按钮。



代码：

Hello,

Please refer to this image

What i am trying to do is on selecting date in first textbox. e.g. 14th june 2013,generate the gridview shown there with 5 dates(other dates will be calculated based on selected date in textbox). And below the gridview theres a button.

Code:

protected void BindEmptyGrid()
{
  try
  {
    DataTable dtab = daNewTable();
    DateTime todate_ = Convert.ToDateTime(Session["1"]);
    DateTime fromdate_ = Convert.ToDateTime(Session["2"]);
    TextBox1.Text = ChangeFormat(Convert.ToDateTime(todate_), "dd/MM/yyyy");
    string[] weekdates = new string[5];
    DataRow d = dtab.NewRow();               
    for (DateTime date1 = fromdate_; date1 <= todate_; date1 = date1.AddDays(1))
    {
     DataColumn dc = new DataColumn();
     dc.ColumnName = ChangeFormat(Convert.ToDateTime(date1), "dd-MM-yyyy");
     dtab.Columns.Add(dc);
    }
    dtab.Rows.Add();
    if (weekdates.Length > 0)
    {
     timegrid.DataSource = dtab;
     timegrid.DataBind();
    }
  }
  catch (Exception ex)
  {
    throw ex;
  }
}
public DataTable daNewTable()
{
  DataTable dtempty = new DataTable();           
  return dtempty;
}

但我面临两个问题。



1）我想在生成的行中有文本框（即5个日期），而我只获得空行？



2）如何访问gridview字段来自button_click事件，其中按钮位于gridview之外？



我非常感谢这方面的任何帮助。

But i am facing two problems.

1) I want to have textbox in the generated rows(that is 5 dates),whereas i am getting only empty rows?

2) How to access gridview fields from button_click event where the button is located outside the gridview?

I really appreciate any help in this regard.

您可以尝试这样的事情：

You can try something like this:

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow row in GridView1.Rows)
        {
            if (row.RowType == DataControlRowType.DataRow)
            {
                TextBox textBox = row.FindControl("TextBox1") as TextBox;
                // do somthing with the text box textBox
            }
        }
    }
