how do i get a SQL timestamp into/out of a grid?

[Craig G]

i have a hidden template column that contains a label which is populated
with a SQL Timestamp. the problem is each time i bring the timestamp out it
is coming out as "System.Byte[]" which is just a string

i understand that the timestamp cannot be seen as its binary but what/how am
i meant to store it in within the grid and then return it out if the user
selects that particular record

ive just been using this to return other fields but that wont work for the
timestamp
myTimeStamp = CType(e.Item.Cells(5).Controls(1), Label).Text

anyone any idea's?

Cheers,
Craig

The timestamp column is not really designed to be a human friendly field. It
is useful in concurrency management, if you design your own, and has other
uses, as well. If you want to display as a numeric value, try something like:

for(int i=timestamp.Length;i>0;i--)
{
result += (byt[i-1] * calc);
calc *= 256;
}

This will calculate the value of all of the bytes in the array. Then display
result.ToString();

'* store in field
CType(e.Item.Cells(5).Controls(1), Label).Text.Text =
System.ConvertToBase64String(myTimeStamp)

'* fetch from field
myTimeStamp = System.ConvertFromBase64(CType(e.Item.Cells(5).Controls(1),
Label).Text)

"The timestamp column is not really designed to be a human friendly field" -
i doubt they could make it anymore unfriendly!!


anyhow, when i do the following i get an error saying - Value of type
'String' cannot be converted to '1-dimensional array of Byte'.

myTimeStamp = Convert.ToBase64String(CType(e.Item.Cells(5).Controls(1),
Label).Text)

opps

should read
myTimeStamp = Convert.FromBase64String(CType(e.Item.Cells(5).Controls(1),
Label).Text)

but i still get the 1-dimensional array of byte cannot be converted to
string

alas i got there in the end!!
