hi i am using asp.net with c# i get this problem when i try to enter date grater than 12 "String was not recognized as a valid DateTime."

i am using sql server 2005. In the table field is in datetime format.In the procedure its is also taking as datetime.and the codes are

DateTime dob = Convert.ToDateTime(txtdob.Text.ToString().Trim());
rec.Add("dob", dob); rec is a hash table.

and the regional setting short date time :MM/dd/yyyy

please help

hi,

use below way..I think its help you

write
dob.ToShortDateString();

then it will give MM/dd/YYYY formate

DateTime dob = Convert.ToDateTime(txtdob.Text.ToString().Trim());
rec.Add("dob", dob.ToShortDateString());

same problem arrise ,even execution is not go to the second line.its immidiately jump to catch()

Hashtable hs = new Hashtable();
DateTime dt = Convert.ToDateTime(TextBox2.Text);
hs.Add("lakshman", dt.ToShortDateString());

using this above code it is working.....let me know any cooncerns

Hashtable rec = new Hashtable();
DateTime dob = Convert.ToDateTime(txtdob.Text.Trim());
rec.Add("dob", dob.ToShortDateString());
why the second line not executing .i have gave a brak point to see the flow ,but after the first line its jump to catch()

Where you wrote this code?...If you write this code in page load it's not work....Why because when you run the application first it runs the page load....that time we haven't give any value to text box.....

If you write this code in any other event it will work....check this and let me know.....

sir i am using this code in the submit event
not in page load.
protected void btnSave_Click(object sender, System.EventArgs e)
{
try
{
Hashtable rec = new Hashtable();
if (txtdob.Text.Length != 0)
{
DateTime dob = Convert.ToDateTime(txtdob.Text.Trim());
rec.Add("dob", dob.ToShortDateString());
}
}
catch( Exception ex)
{
lblerror.visible=true;
lbl.text=ex.Message;
}
}
}

are you giving value in txtdob????

yes 13/11/1983

IF you write MM/DD/YYYY formate it is not giving any error.....

If you write DD/MM/YYYY formate it is giving error when you convert to datetime....

try this way and let me know
