Hi Morris,
Based on my understanding, you are able to update the existing records but
cannot insert new records to the database. If I'm off base, please feel
free to let me know.
I perform a test but couldn't reproduce the problem on my side. The main
steps of my test are as follows:
1. Use "Data Source Configuration Wizard" to add a DataSet containing a
DataTable into the project(select menu Data| Add New Data Source¡), which
also generates a TableAdapter for the DataTable.
2. Open the "Data Sources window" (select menu Data | Show Data Sources).
3. From the Data Sources window, click the drop down button on the right
of the DataTable and select "Details" and then drag the DataTable onto a
Form, which generates several controls, a DataSet instance, a BindinSource,
a TableAdapter as well as a BindingNavigator.
4. Delete the BindingNavigator from the Form.
5. Add two Buttons on the Form and handle the Click event of these two
Buttons.
// add a new record
private void button1_Click(object sender, EventArgs e)
{
this.bindingSource1.AddNew();
}
// save changes back to DB
private void button2_Click(object sender, EventArgs e)
{
this.Validate();
this.bindingSource1.EndEdit();
this.tableAdapter1.Update(this.dataSet1.Table1);
}
Since I couldn't reproduce the problem using the same lines of code as
yours, I suspect the reason of your problem is that the InsertCommand is
missing in the TableAdapter for your DataTable. I recommend you check
whether there's an InsertCommand in the TableAdapter or not. To do this:
1. In the Solution Explorer, double click the DataSet file(.xsd file) to
open the DataSet designer.
2. In the DataSet designer, click on the xxxTableAdapter panel and switch
to the Properties window.
3. In the Properties window, check the value of the InsertCommand property.
If the InsertCommand property is (none), click the new option in the drop
down list, and then specify the 'Command Text' and 'Parameters' properties
for the InsertCommand.
Please try my suggestion and let me know the result.
If the problem is still not solved, you may reproduce the problem in a
simple project and send it to me. To get my actual email address, remove
'online' from my displayed email address.
Sincerely,
Linda Liu
