[RESOLVED] Bound Unbound gridview problem

Hii
I have a gridview in which 4 columns are bound and 2 unbound.
Iam using VS2005 with vb.net

HTML Code:

---

Q1) How to get the unbound columns at the end of bound columns. (currently unbound columns are coming first)

Q2) How to show the value of difference of two bound columns in unbound column.
e.g)
TotalQty  QtyOrdered  Balance
10          4              6
15          8              7

Q3) How to put condition in gridview column.
e.g)
TotalQty  QtyOrdered  Balance  Order
10          4              6         
15          8              7

if i put 8 in order column of first row it shows message that you cannot order more than total quantity

Balance and Order are unbound columns.[QUOTE][/QUOTE]

Hey,

I am not sure that I follow exactly what you are getting at.

Can you show the code that you are currently using? Both the ASPX markup, and any server side code?

Gary

Thanks
Problem solved

Hey,

For the benefit of other people in the forum, perhaps with a similar issue, it would be good if you can post the solution that you came up with.

Also, if you have solved your problem, remember to mark your thread as resolved.

Place a RangeValidator next to your textbox in your templatefield in your gridview; and assign it to the textbox. Set its range to a maximum of 8. If the user enters something higher than 8, it should prevent the form from submitting.
