Hi Akhter,

You have to check your down condition out side of below condition.

if (!string.IsNullOrEmpty(txtINTime.Text) && !string.IsNullOrEmpty(txtOuttime.Text))
{}

INTIME	OUTTIME	HOURS
2018-05-26 9:22:00	2018-05-26 9:22:00	8
	2018-05-26 9:22:00	0

i am using this code on page load

protected void GVEAtt_RowDataBound(object sender, GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.DataRow)

{

TextBox txtINTime = e.Row.FindControl("txtINTime") as TextBox;

TextBox txtOuttime = e.Row.FindControl("txtOuttime") as TextBox;

if (!string.IsNullOrEmpty(txtINTime.Text) && !string.IsNullOrEmpty(txtOuttime.Text))

{

DateTime INTIME = Convert.ToDateTime(txtINTime.Text);

DateTime OUTTime = Convert.ToDateTime(txtOuttime.Text);

TextBox txtOT = e.Row.FindControl("txtOT") as TextBox;

TextBox txtDuty = e.Row.FindControl("txtDuty") as TextBox;

TextBox txtHours = e.Row.FindControl("txtHours") as TextBox;

TextBox txtOTAmount = e.Row.FindControl("txtOTAmount") as TextBox;

TextBox txtLTime = e.Row.FindControl("txtLTime") as TextBox;

TextBox txtOTRate = e.Row.FindControl("txtOTRate") as TextBox;

TextBox txtDays = e.Row.FindControl("txtDays") as TextBox;

TextBox txtOTEntitled = e.Row.FindControl("txtOTEntitled") as TextBox;

TextBox txtINTIME = e.Row.FindControl("txtINTIME") as TextBox;

Label lblStatus = (Label)e.Row.FindControl("lblStatus");

txtHours.Text = OUTTime.Subtract(INTIME).Hours.ToString();

txtDays.Text = OUTTime.Subtract(INTIME).Days.ToString();

int t1;

int t2;

int t3;

int t4;

int t5;

txtDuty.Text = "8";

txtOTAmount.Text = "0";

txtOT.Text = "0";

// txtLate.Text = "1";

txtOTRate.Text = "100".ToString();

txtLTime.Text = "9:10".ToString();

t1 = int.Parse(txtHours.Text);

t2 = int.Parse(txtDuty.Text);

t3 = int.Parse(txtOTAmount.Text);

t4 = int.Parse(txtOTRate.Text);

t5 = int.Parse(txtOT.Text);

// t6 = int.Parse(txtINTIME.Text);

{

if (string.IsNullOrEmpty(txtINTIME.Text))

{

txtHours.Text = "0";

}

but below area code is not working

@Jignesh Kumar
You can not assign 0 to textbox as it only accept string value. So, instead of
txthours.Text = 0;
should be
txthours.Text = "0";

Can you explain the problem in details as I can understand that you are trying to check that in a textbox the date value is selected or not. If not selected then in other textbox you want to put 0 as hours otherwise you want to do calculation.

In this situation provided code will work if other requirement please provide in detail requirement.

Hi Akhter,

@Suraj Kumar, Thanks for feedback, I have done correction
if(string.IsNullOrEmpty(datetime.Text))
{
// Assign zero
txthours.Text = "0";
}
else {
// convert values to time
}

You can try this
if (string.IsNullOrEmpty(Convert.ToString(datetime.Text)))
{
    txthours.Text = "0";
}
else
{
    //Write your logic here.
}
