hi all,
txtcaseNo.DataBindings.Add("number", dset13, "case");
txtrentstart.DataBindings.Add("date", dset13, "rentstart");
txtrentend.DataBindings.Add("date", dset13, "rentend");
txtrentduration.DataBindings.Add("number", dset13, "rentduration");
cmbCOHour.DataBindings.Add("date", dset13, "COHour");
txtcurrencytype.DataBindings.Add("text", dset13, "currencytype");
txtdailytotap.DataBindings.Add("number", dset13, "dailytotal");
txttotal.DataBindings.Add("number", dset13, "total");
this code gives an error like this: cant bind number ?
my database fields are :
number, date/time, date/time, number, date/time, text, number, number respectively. how should i change the first properties in binding (bold parts)?
help please,
thanks in advance.

i think what ever u have witten in bold letters are data types of coloumns
of table but u should put controls property to bind there
like if txtcaseNo is text box then data binding should be
txtcaseNo.DataBindings.Add("Text", dset13, "case");
where Text is text property of textbox to be bind.

I don't know if this is the right board for this, if not I'm sure someone will tell me.
I am developing a C#.NET application for the market, which will be sold over the internet by making a trial version (with limits on facilities and use time) available free, and providing an unlocking mechanism on receipt of payment. All standard stuff - except I've never done it before.
Can anyone recommend a good guide to how to do this, or even a developers' toolkit for generating/recognising keys and all that stuff.

hi all,
i have a few textboxes and a datagridview.
SelectionMode is 'FullRowSelect'. when the selected row changes, i want to change the textboxes.texts to change according to the data in datagridview.
i have a code like this :
txtKullanici.Text = dataGridView3.Rows[dataGridView3.SelectedRows.Count -1 ].Cells[0].Value.ToString();
txtSifre.Text = dataGridView3.Rows[dataGridView3.SelectedRows.Count -1 ].Cells[1].Value.ToString();
txtSifreT.Text = txtSifre.Text;
cmbYetkiS.Text = dataGridView3.Rows[dataGridView3.SelectedRows.Count -1].Cells[2].Value.ToString();
in which event should i put these codes ?
help please,
thanks in advance.

Never worked with DataGridView, but after a quick glance at the docs I would say SelectionChanged sounds suitable.

Try this:
private void DataGridView1_RowEnter(object sender, DataGridViewCellEventArgs e)
{
if(DataGridView1.CurrentRow != null)
textbox1.Text = DataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();
}
Regards.

First : you must write a code in Managed C++ to wrap your Unmanaged C++ code.
Second : Use your Managed C++ Classes in your C# Code.

how to insert values from controls to different interrelated tables in database
-- modified at 3:28 Tuesday 6th June, 2006
|
|
|
|
|
The best way is to write a stored procedure and call it with the values from your controls.
What's the database ? Have you looked on the site for examples ( in the articles section ) ? What about msdn ? You can use google to search msdn by putting site:msdn.microsoft.com at the end
