Hello all, I've pasted in my code that doesn't seem to work. I can raise the
grdLinks_ItemCommand event, but for some reason e.CommandName is = "", event
though in gdrLink_ItemDataBound I'm setting it to be AddFAQ. WHy is that?

I assume that you set CommandName="AddFAQ" as property of the DataGrid. You

Hi Ollie, unfortunately that didn't work either :(. In my despiration I've
re-written it!

Thanks for your efforts though,

sorry I meant ItemCreated

Jon said:
Hello Ollie,

There is no Data Create event for a datagrid, there's the ItemCreated event?

Thanks,

Ollie Riches said:
move the code from the data bind event to the data create event for the
datagrid and that should work

HTH

Ollie Riches

Kostadin, I'm setting commandName = "AddFAQ" in code under the
ItemDataBind
Event

Thanks,

Jon

:

I assume that you set CommandName="AddFAQ" as property of the DataGrid.
You
have to set the CommandName as property of the control that causes the
command inside the datagrid - LinkButton, Button or whatever it is.

Hope that helps!
Regards,
Kostadin Kostov

Hello all, I've pasted in my code that doesn't seem to work. I can
raise the
grdLinks_ItemCommand event, but for some reason e.CommandName is = "",
event
though in gdrLink_ItemDataBound I'm setting it to be AddFAQ. WHy is
that?

Thanks,
