System.IndexOutOfRangeException: 'There is no row at position 10000' (in DataTable)

Question

After converting my DataGrid.ItemsSource to DataTable to extract the column 3 value of each row of DataTable, and also when I select all rows of DataGrid using Ctrl +A and wish to delete them, I receive the following error: System.IndexOutOfRangeException: 'There is no row at position 10000'

Whereas BookDataGrid.SelectedItems.Count is 20,000.
The following information may assist you in resolving the issue:
When there were 30,000 rows in the DataGrid, the error mentioned above happened at row 15,000.
For instance, I think this error will occur on row 20,000 if there are 40,000 rows.

Answer 1

Try this:

. . .  
for (int i = 0; i < BookDataGrid.SelectedItems.Count; i++)  
{  
   BookCodeSelectedItems[i] = uint.Parse(DT.Rows[i][3].ToString());  
}  
DT.Rows.Clear( );  
. . .  

Answer 2

I knew but forgot that I needed to use a descending For loop to utilize the Remove function on arrays because when a value is removed from the array, the Count value is decremented and the Count will error halfway through the loop.
Therefore, the codes need to be changed as follows:
Note: i >= 0 (in descending For loop) because the index of the DataGrid's first row begins at zero
C#:

    private void DataGridDeleteMenu_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)  
    {  
        switch (BookDataGrid.SelectedItems.Count > 0)  
        {  
            case false:  
                MessageWindow MW = new MessageWindow();  
                MW.YesButton.Visibility = Visibility.Hidden;  
                MW.NoButton.Visibility = Visibility.Hidden;  
                MW.MessageLabel.Margin = new Thickness(0, 110, 0, 0);  
                MW.MessageLabel.HorizontalAlignment = HorizontalAlignment.Center;  
                MW.Image.Source = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Warning.bin"));  
                MW.MessageTextBlock.Text = "No rows selected";  
                MW.OKButton.Content = "OK";  
                MW.ShowDialog();  
                break;  
            default:  
                DataTable DT = ((DataView)BookDataGrid.ItemsSource).ToTable();  
                ISBN_Value = new string[BookDataGrid.SelectedItems.Count];  
                BookCodeSelectedItems = new uint[BookDataGrid.SelectedItems.Count];  
                //"i >= 0" because the index of the DataGrid's first row begins at zero  
                for (int i = BookDataGrid.SelectedItems.Count - 1; i >= 0; i--)  
                {  
                    BookCodeSelectedItems[i] = uint.Parse(DT.Rows[i][3].ToString());  
                    DT.Rows.RemoveAt(i);  
                }  
                BookDataGrid.ItemsSource = DT.DefaultView;  
                break;  
        }  
    }  

Output:
