Gridview Headers for ItemTemplate and EditTemplate

[theWizard1]

In Display mode, my gridview should display FullName and Phone, and in edit
mode it should display firstname, lastname, phone, and ext.

The gridview is working except for displaying the headers properly.

Currently in display it is showing header for FirstName, Fullname, Phone,
and Ext. It should only show FullName and Phone. The contents in the
FullName are correct, concatenated LastName and FirstName. The contents in
Phone are correct, concatenated Phone and Ext in Phone.

When in edit mode, it is displaying the headers and content correctly except
for LastName, which is shown with a header of FullName.

Can someone assist regarding how to do this.

The gridview follows:

**********************************************************

The phone in display mode shows phone number plus the ext, if an ext exists,
as required by my users.

I am using 2 methods in my codebehind to format this:

public string FormatPhone(string myPhone)
{
string strFormattedString;
if( myPhone == null || myPhone.ToString().Length == 0)
{ strFormattedString = ""; }
else
{
string strPhone = myPhone.ToString();
strPhone = strPhone.Replace(",", "");
strPhone = strPhone.Replace("-", "");

strFormattedString = String.Format("{0:### ###-####}",
Int64.Parse(strPhone));
}
return strFormattedString;
}
public string FormatExt(string myExt)
{
string strFormattedExt;
if (myExt == null || myExt.ToString().Length == 0)
{ strFormattedExt = ""; }
else
{
string strExt = myExt.ToString();
strExt = strExt.Replace(",", "");
strExt = strExt.Replace("-", "");

strFormattedExt = "ext." + strExt;
}
return strFormattedExt;
}

Please help.
