Hello Sir,

I have a gridview on my webpage

In the gridview, Textboxes are placed below every field,

My question is how to find time difference as by finding control in gridview

Like StartTime: 09:30<br />
<br />
      EndTime:  10:30

TotalTime Should come as by calculating difference between EndTime and StartTime

Like: EndTime-StartTime=> 10:30-09:30=1(TotalTime)

I have to do this by coding in C#

My problem is I am unable to findContol in gridview when calculating TotalTime

S.No.   StartTime   EndTime   TotalTime<br />
 1        09:30      10:30

How Could I calculate Please guide me and provide some links so that I can solve my problem

C#

DateTime dFrom;
        DateTime dTo;
        string sDateFrom = "11:56:00";
        string sDateTo = "12:12:00";
        if (DateTime.TryParse(sDateFrom, out dFrom) && DateTime.TryParse(sDateTo, out dTo))
        {
            TimeSpan TS = dTo - dFrom;
            int hour = TS.Hours;
            int mins = TS.Minutes;
            int secs = TS.Seconds;
            string timeDiff = hour.ToString("00") + ":" + mins.ToString("00") + ":" + secs.ToString("00");
            Response.Write(timeDiff); //output 16 mins in format 00:16:00
        }

Thanks Rakesh for this code I solved myself but by use of your code

My code is:
protected void txtStartTime_TextChanged1(object sender, EventArgs e)
{
filltime();
//int rowindex = grdDaily.SelectedIndex;
// TextBox txtStartTime = (TextBox)grdDaily.Rows[rowindex].FindControl("txtStartTime");
//TextBox txtEndTime = (TextBox)grdDaily.Rows[rowindex].FindControl("txtEndTime");
//TextBox txtTotalTime = (TextBox)grdDaily.Rows[rowindex].FindControl("txtTotalTime");
//int diff=TimeSpan
//txtTotalTime.Text=Convert.
}
public void filltime()
{
int rowindex = Convert.ToInt16(ViewState["RowIndex"]);
TextBox txtStartTime = (TextBox)grdDaily.Rows[rowindex].FindControl("txtStartTime");
TextBox txtEndTime = (TextBox)grdDaily.Rows[rowindex].FindControl("txtEndTime");
TextBox txtTotalTime = (TextBox)grdDaily.Rows[rowindex].FindControl("txtTotalTime");
DateTime ST;
DateTime ET;
string StartTime = txtStartTime.Text + ":00";
string EndTime = txtEndTime.Text + ":00";
if (DateTime.TryParse(StartTime, out ST) && DateTime.TryParse(EndTime, out ET))
{
TimeSpan TS = ET - ST;
int hour = TS.Hours;
//int mins = TS.Minutes;
// int secs = TS.Seconds;
string timeDiff = hour.ToString("00");// +":" + mins.ToString("00"); //+ ":" + secs.ToString("00");
//Response.Write(timeDiff); //output 16 mins in format 00:16:00 }
txtTotalTime.Text = timeDiff;
}
}
