类别1



chk记录1

chk记录2

chk记录3

类别2



chk记录4

chk记录5

等

Hi,

I'm databinding the checkbox list to a db table which has a category assigned for multiple records. I can list the checkbox but I can't sort them by category using the checkbox list control. Can somebody post an example on how to achieve this? Thank You!

Category 1

chk Record 1
chk Record 2
chk Record 3
Category 2

chk record 4
chk record 5
Etc

For example take a look on the below link
