i think behaviour of required validation control is to prevent page postback if field is empty.

hi friends
how to find the column index using column name in datagrid
regards
sara

If the columns are not auto-generated, you can use datagrid Columns
collection. Write a utility function that will take a column name as a
parameter, loop through Columns collection, find a column with matching
name, get it's index and return Cells element with the same index.

It is difficult to track the error with this information. Find the exact position where the error occurring. Then it is easy to find a solution.
|
|
|
|
|
actually when i load simple page without master page it works fine
locally and same after publishing...
but when i use master page on that page and then open it in a new window it works fine locally but not after publishing....
means master page gives object reference error in new window.....

There are no built-in classes for POP3. You have to write your own POP3 or buy any third party controls.
