Raiseevent user control in user control

 Hi there,


I am working on a project in which a user control (BedrijfMasterDatagrid.ascx) is creating an other user control (BedrijfDatagrid.ascx).
The user control BedrijfDatagrid.ascx is correctly created, but the clicked event of the created image control (BedrijfDatagrid.ibImageButtonClicked ) is not fired. (see BedrijfDetail.aspx)
When I place BedrijfDatagrid.ascx directly on the page the event is correctly fired.


Summary:
BedrijfMasterDatagrid.ascx:       Datagrid with 1 row in which BedrijfDatagrid is dynamically created
BedrijfDatagrid.ascx                  Datagrid with 1 row including a imagebuton which clicked event should be fired
BedrijfDetail.aspx                      aspx webpage in which BedrijfMasterDatagrid.ascx is placed. In this page I want to use the event BedrijfDatagrid.ibImageButtonClicked, but this event is not fired!!!


Does anybody have a clue what I do wrong?


Many thanx for you help!

Below the code I use:

Hi,


Based on my knowledge, if you want to fire a child control event, you need to know the event bubbling mechenism in user control, the event fired from child control can continue to pass through layers, starting at the bottom (the user control) and perhaps reaching the top level.


For more details on how to pass your child control events to top layer, see:

Thanks.
