I'm trying to bind a datagridview from a datable using stored procedure and I have a calendar column in my datagridview, I try this code by it a gives me always the last value in the calendar column:

C#

grdEmployees.Rows.Clear();
           objGet = new GetClass();
           DataTable dt = objGet.GetValues("GetVacationForStartWork", txtEmployeeCode.Text.Trim());
           for (Int32 i = 0; i < dt.Rows.Count; i++)
           {
 grdEmployees.Rows.Add(Convert.ToDateTime(dt.Rows[i]["StartDate"]).ToString("MM/dd/yyyy")
                   , Convert.ToDateTime(dt.Rows[i]["EndDate"]).ToString("MM/dd/yyyy"),
                   dt.Rows[i]["IDVacation"]

             );
            

           }
           foreach (DataGridViewRow row in grdEmployees.Rows)
               {
                   for (Int32 i = 0; i < dt.Rows.Count; i++)
                   {
                       try
                       {
row.Cells["WorkStart"].Value = Convert.ToDateTime(row.Cells["EndDate"].Value).AddDays(1);
row.Cells["ConfirmedWorkStarted"].Value = Convert.ToDateTime(dt.Rows[i]["ConfirmedWorkStarted"]);
                       }
                       catch (Exception ex)
                       {
                           MessageBox.Show(ex.Message);
                       }

                   }

           }

My stored procedure output:

StartDate       EndDate         IDVacation     ConfirmedWorkStarted

2015-06-06	2015-06-26	  19	        6/30/2015 12:00:00 AM
2015-07-20	2015-07-25	  18	        7/27/2015 12:00:00 AM

DataGridView output:

CSS

StartDate       EndDate         IDVacation     ConfirmedWorkStarted

2015-06-06     2015-06-26           19                 7/27/2015 
2015-07-20     2015-07-25           18                 7/27/2015

Please see the column "ConfirmedWorkStarted" in the stored procedure output and in the datagridview output , they are not the same!

Solution 1

Im not shure but Replace

C#

row.Cells["ConfirmedWorkStarted"].Value = Convert.ToDateTime(dt.Rows[i]["ConfirmedWorkStarted"]);

with:

C#

row.Cells["ConfirmedWorkStarted"].Value = Convert.ToDateTime(row.Cells["ConfirmedWorkStarted"])

The issue is with iterating the loops. Which is not correct. I did a sample on this. Check below.

DataTable dt = new DataTable();
dt.Columns.Add("StartDate");
dt.Columns.Add("EndDate");
dt.Columns.Add("IDVacation");
dt.Columns.Add("ConfirmedWorkStarted");

DataRow dr = dt.NewRow();
dr["StartDate"]="2015-06-06";
dr["EndDate"]="2015-06-26";
dr["IDVacation"]="19";
dr["ConfirmedWorkStarted"]="6/30/2015 12:00:00 AM";
dt.Rows.Add(dr);

DataRow dr1 = dt.NewRow();
dr1["StartDate"]="2015-07-20";
dr1["EndDate"]="2015-07-25";
dr1["IDVacation"]="18";
dr1["ConfirmedWorkStarted"]="7/27/2015 12:00:00 AM";
dt.Rows.Add(dr1);

grdEmployees.DataSource = dt;
grdEmployees.DataBind();

foreach (GridViewRow row in grdEmployees.Rows)
{
row.Cells[3].Text = Convert.ToDateTime(row.Cells[3].Text).ToShortDateString();

}

You can remove hard codes "3" and put your own counter i in it. Hope this works.
