Hi,

I've been working on the example for adding, deleting, and editing table 
rows. It's located on pages 504 through 507 in the book. In part 5 of the 
example on page 506, there seems to be an error. Since I couldn't find 
any typos, I actually went to the downloaded source code and copied this 
section into my page (the rest of the page works fine except for this one 
area). This is the code:

//Marker 2
  //Find the row to change
    DataRow[] objRows = objTable.Select("FirstName='Margaret' AND 
LastName='Peacock'");
    objRows[0]["FirstName"] = "John";
    objRows[0]["LastName"] = "Hartford";

    // Bind the data grid to the new data
    dgNameList3.DataSource = objTable.DefaultView;
    dgNameList3.DataBind();

And this is the error message I get:

Index was outside the bounds of the array. 
Description: An unhandled exception occurred during the execution of the 
current web request. Please review the stack trace for more information 
about the error and where it originated in the code. 

Exception Details: System.IndexOutOfRangeException: Index was outside the 
bounds of the array.

Source Error (highlighted for Line 40): 


Line 38:   // Find the row to change
Line 39:     DataRow[] objRows = objTable.Select("FirstName='Margaret' 
AND LastName='Peacock'");
Line 40:     objRows[4]["FirstName"] = "John";
Line 41:     objRows[4]["LastName"] = "Hartford";
Line 42: 
 
Can anyone tell me how to fix this? I didn't find any errata listed for 
chapter 13 on the site.

Thanks in advance for any help.

Hi Phil,

I appreciate your guidance in explaining the support process to me. 
However, I have not received a reply to my email, except to say it was 
being passed along. So I'm still wondering if anyone out there can see 
the mistake in this code example.

Thanks,
Kim
