Datagrid problem

[Raj Anand]

I have a dataview and binding to a datagrid. On
ItemBound I'm adding a checkbox dynamically for each
rows. It works ok but my problem is on checkedChanged i
have addded a eventHandler..i t's not getting fire at all
In aspx file. Somebody, suggested me to add
<%# chk_Click()%> in my aspx file but it didn't work..Any
help in this regard is appreciated.

Thanks
