dotnet ado.net : Tableadapter.update not working
Can anyone tell me why this code added automatically by C# does not work? I
can add a record on the form or modify a record, but hitting the save button does not save changes back to the database table. I can see the chnages to the dataset as long as the form is still loaded. private void customerBindingNavigatorSaveItem_Click(object sender, EventArgs e) { this.Validate(); this.customerBindingSource.EndEdit(); this.customerTableAdapter.Update(this.accessTest1DataSet.Customer);
Miha Markic,
Please excure my ignorance. How do you "set" these methods? [quoted text, click to view] "Miha Markic [MVP C#]" wrote:

I dragged the data source over to the form and it created all the code.
Funny, I did exactly what I saw in this traning view for binding data on C# web site. The authors example works, mine does not. The code is same. But maybe there is a problem in the code genertaed by C# automatically. Not sure. THis is wierd. And Itried the same thing at work and I am getting the same result.

Chris,
Could it be that you are actually updating a copy of your database? See: http://msdn2.microsoft.com/en-us/library/ms246989.aspx Kerry Moorman [quoted text, click to view] "Chris" wrote:

Many of us have been confused by this new helpful "feature" of VS2K5 designed to assist us in the distribution of our applications. If possible I always leave the Database (Access, SQL Express, etc.) out of the project until all testing is done and add it just before deployment. Good luck with your project, Otis Mukinfus http://www.arltex.com
