Block parameter binding problem
Hello,
I have a complex component which renders several Blocks. I can pass parameters to the Block by passing them as informal parameters to the RenderBlock.
My problem is that these parameters are available only at render time but not when a link declared in a Block is triggered (inserter is null in the listener method).
How can I workaround this? How can I make these informal parameters "auto"?
Thanks,
Norbi

I think that StaleLinks should not occur if you use ListEdit and
FormConditional instead of Foreach and Condition, but you know your
application best :)
I guess the alternative is to try to encode what you need in the parameters
of the DirectLink. That way you will not rely on the parameters.

I had to be more precise: the data I display in my component changes
frequently. So using ActionLink may often cause stale links.

I would disagree with that.
There are a number of cases where ActionLink is helpful and this is probably
the poster example. If your page is build dynamically (say with Blocks) and
you cannot encode what you need in the Direct parameters (or it is not
practical, which is also a typical case), ActionLink is your only refuge.

Thanks for the tip.
Although - as I know - it is not recommended to use ActionLink. (Howard said
that he wanted to remove ActionLink, now it exists mainly for prototyping.)

Hi,
Try using ActionLink rather than DirectLink in this case, I believe this
will help.
