if (e.Item.ItemType != ListItemType.Header)

          _objTT.GridHeading(vid, e);

          //cT.date = Convert.ToDateTime((object)DateTime.Today.Date);
          //cT.a = Convert.ToInt32((object)Hidden1.Value);
          //DataSet ds = cT.Getdate();

          if (ds.Tables[0].Rows.Count > 0)
          {
              for (int j = 0; j < ds.Tables[0].Rows.Count; j++)
              {
                  for (int index = 1; index <= 7; ++index)
                  {
                      if (vid.Columns[index].HeaderText == ds.Tables[0].Rows[j]["Day"].ToString())
                      {
                          //e.Item.Cells[index].Text = dr["Day"].ToString() + "<Br>" + dr["Date"].ToString();
                          //vid.Columns[index].HeaderText = dr["Day"].ToString() + "<Br>" + dr["Date"].ToString();
                          e.Item.Cells[index].Text = ds.Tables[0].Rows[j]["Day"].ToString() + "<Br>" + txtentrydate.Text;

If you have a DateTime value, then the day of the week is simple:

DateTime now = DateTime.Now;
string dayOfWeek = now.DayOfWeek.ToString();

How the heck would I know? I have no idea what your table is supposed to look like!

Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with - we get no other context for your project.

Solution 2

This should give you a hint if I have understood your issue correctly.

C#

if (vid.Columns[index].HeaderText == ds.Tables[0].Rows[j]["Day"].ToString())
{
  DateTime _tmp = dr["Day"] // assuming the object is DateTime.
  e.Item.Cells[index].Text =  _tmp.DayOfWeek.ToString() + "<Br>" + _tmp.DayOfWeek.ToString();
  //vid.Columns[index].HeaderText = dr["Day"].ToString() + "<Br>" + dr["Date"].ToString();
  e.Item.Cells[index].Text = ds.Tables[0].Rows[j]["Day"].ToString() + "<Br>" + txtentrydate.Text;
  vid.Columns[index].HeaderText = ds.Tables[0].Rows[j]["Day"].ToString() + "<Br>" + txtentrydate.Text;
}

 protected void vid_ItemDataBound(object sender, DataGridItemEventArgs e)
   {
       try
       {
           if (e.Item.ItemType != ListItemType.Header)
               return;
           _objTT.GridHeading(vid, e);

           string dayOfWeek = DateTime.ParseExact(txtentrydate.Text,"dd-MM-yyyy",CultureInfo.InvariantCulture).DayOfWeek.ToString();

}
       catch (Exception ex)
       {
           Log.Message(ex);
       }
   }
