textbox18 is date retrieved from database in database the date is saved like dd/MM/yyyy format.

DateTime addonday = Convert.ToDateTime(TextBox18.Text);

correct answer is
DateTime dateTime = Convert.ToDateTime(this.TextBox18.Text.Trim(), new CultureInfo("en-GB"));
this.TextBox20.Text = dateTime.AddDays(1).ToString("dd/MM/yyyy");

Just to be clear what appears in TextBox18 when you run the code in your second post to this thread?

If it's 07/01/2014 then try replacing en-GB with en-US.

Replace your code

DateTime dateTime = Convert.ToDateTime(this.TextBox18.Text.Trim(), new CultureInfo("en-GB"));
this.TextBox20.Text = dateTime.AddDays(1).ToString("dd/MM/yyyy");

with below code

string d = dr["lastdate"].ToString();

this.TextBox20.Text = (DateTime.Parse(d).AddDays(1)).ToShortDateString();

me fetch the textbox18 from sql server
my code is
DataSet dssf = new DataSet();
string qws = "select max(date) as lastdate from aten where id='" + rtid.Text + "' and Status='" + TextBox19.Text; qws += "'";
dssf = mvl.GETDS(qws);
foreach (DataRow dr in dssf.Tables[0].Rows)
{
TextBox18.Text = dr["lastdate"].ToString();
DateTime dateTime = Convert.ToDateTime(this.TextBox18.Text.Trim(), new CultureInfo("en-GB"));
this.TextBox20.Text = dateTime.AddDays(1).ToString("dd/MM/yyyy");
}

Hi

Try this code

TextBox20.Text = (DateTime.Parse(TextBox18.Text).AddDays(1)).ToShortDateString();
