i have a gridview with check box in it and I also have a button separately.
The gridview contains students name and their school name.
User will select rows in gridview with the check box and click the button.
Now what I want is, if user select students from two different school, system will display message ("wrong selection").
But if user select student with in the same school, system will work as it should be.
so, how can I compare the rows?? any help??
