bindings & date format
Hi to all!
I am getting an error when I try to do the next format adjustment:
Binding b50;
b50 = new Binding("Text", dsPacientes, "PACIENTES.pac_fecha_nac");
b50.Format += new ConvertEventHandler(this.txtFechaFormat);
txtFechaNac.DataBindings.Add(b50);
...
private void txtFechaFormat(object sender, ConvertEventArgs e)
{
DateTime dt = (DateTime) e.Value;
e.Value = dt.ToString("MM/dd/yyyy hh:mm:sszzz");
}
The problem is inside the function "txtFechaFormat". I've tried out with diff formats, with no results.
Does anybody can help me?
Thanks

WE can best help people when they provide the error they are getting.
That said, i might be missing something- but this code doesn't even look like it's close to being correct.

Ok. The error is:
'System.InvalidCastException' in system.windows.forms.dll
Additional information: The specified conversion is not valid.
I hope it helps.

Thanks Hal,
I've finally solved, in the way:
private void txtFechaFormat(object sender, ConvertEventArgs e)
{
DateTime dt = (DateTime) e.Value;
string s = dt.ToString("dd/MM/yyyy");
e.Value = s;
}
I really don't understand at all, because I am doing the same... or that's what I think... never mind, it works fine.
:)

Hello,
Also in response to Hovik, the date format in your datagrid is based on the date format of the users regional settings. I couldn't figure out a way to change the date format in my datagrid for my non ASP application without changing it in the Regional Settings. If somebody knows of a way and would like to share, please feel free...
