[RESOLVED] Can't save from datagridview to database

[nikel]

Hello, I have a database and after I delete a row I cannot update database, I'm getting error: (edit: please ignore this)

update requires a valid updatecommand when passed datarow collection with deleted rows

... indicating line: sqliteDataAdapter.Update(dataTable);
Here's my code:

private void SaveChanges(bool keepControlsDisabled)
{
    disableControls();
 
    Validate();
    programs_dgv.CommitEdit(DataGridViewDataErrorContexts.Commit);
    programs_dgv.EndEdit();
 
    programs_dgv.DataSource = null;
    programs_dgv.DataSource = bindingSource;
    programs_dgv.Update();
 
    sqliteDataAdapter = new SQLiteDataAdapter();
    sqliteDataAdapter.Update(dataTable);
    dataTable.AcceptChanges();
 
    if (keepControlsDisabled == false)
    {
        enableControls();
    }
}

Here's the delete code:

private void contextMenuStrip_tsmi_Click(object sender, EventArgs e)
{
    Int32 rowToDelete = programs_dgv.Rows.GetFirstRow(DataGridViewElementStates.Selected);
    programs_dgv.Rows.RemoveAt(programs_dgv.CurrentCell.RowIndex);
    programs_dgv.ClearSelection();
}

Is there a universal save function to pass records from datagridview to database?

EDIT: Am on the right way? Do I have to deal with database and display results on datagridview? Or firstly datagridview must be handled? I'm so confused with that. Which one is right for performance?
