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;
}

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.

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
            }
        }
    }

Thank you prasad for your response,the solution is good. I came across the link you provided for textbox problem but i have for loop in which i am assigning the values(dates in header)

for (DateTime date1 = fromdate_; date1 <= todate_; date1 = date1.AddDays(1))
{
DataColumn dc = new DataColumn();
dc.ColumnName = ChangeFormat(Convert.ToDateTime(date1), "dd-MM-yyyy");//this line
dtab.Columns.Add(dc);
}
how to integrate that code in this one,i have tried alot since one and half day and i am getting no result.

I am not sure but try something like this and let me know
for (DateTime date1 = fromdate_; date1 <= todate_; date1 = date1.AddDays(1))
{
DataColumn dc = new DataColumn();
dc.ColumnName = ChangeFormat(Convert.ToDateTime(date1), "dd-MM-yyyy");//this line
d[//Your column name where you want text box] = //your textbox.text;
dtab.Columns.Add(dc);
}
