Problem with DeleteCommand in C#

Hi,

I am setting up a small interface. I have a problem.
I want to create a window in which the future of the software user enter data that could save. My program does not work correctly.
The error that I get is:

Quote:

---

"Update requires a valid DeleteCommand when crossing the DataRow collection with deleted rows."

---

I tried several things but nothing works.

Thank you for help.

The code that corresponds to the error generated would be welcome this suppose to be consider if we need to implement the Delete command in C#,and for this strong logic should be there to get properly implemented.

let it be.If you have a code then please show this will help to understand better

Here is the Code:

Code:

---

public partial class Form1: Form
      (
          public Form1 ()
          (
              InitializeComponent ();
          )

          private void table1BindingNavigatorSaveItem_Click (object sender, EventArgs e)
          (
              this. Validate ();
              this. table1BindingSource. EndEdit ();
              this. tableAdapterManager. updateAll (this. database1DataSet1);

          )

          private void Form1_Load (object sender, EventArgs e)
          (
              / / TODO: This line of code loads the data in table 'database1DataSet1.Table1.  You can move or delete according to your needs.
              this. table1TableAdapter. Fill (this. database1DataSet1. Table1);

          )
      )
  )

At what point it will generate the error? during an update?or an addition? That you forget to mention, and that is important.otherwise on the above it looks pefectly all right.
