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.

Dear Suraj Kumar

this is not working

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.
}
