JQDynaTreeOptionsQueryActivate?

[wieczy123]

Hi,

how does it work? I've try:

on Event ...OptionsQueryActivate:

AParams->Values["flag"] = "false";

but the node can still be activate. Any hints?

Thanks Frank

Hi,

thank you for answer. That's what I want to do:

If the user click to a node in the tree I would like to decide whether the node can be activate or not. I thought I do this in the event:

JQDynaTreeOptionsQueryActive

Right?

Normaly all nodes can be activate by clicking. How can I suppress that the user can activate a node?

Thank you.

Hi wieczy123,

Sorry for delay...

Unfortunately, it's only possible via javascript...

Hi,

The javascript validation is more complex.
Please describe better your procedure/validation.

Hi,

thank you for answer. We have many documents, which the user can edit (e.g. emails, querys, etc.). The document names are the nodes in the tree. If an user has edited a document without saving, the document should not be leaved. In actual fact we need an event "OnQueryDeActivate" or "OnQueryLeave". Because there is only the event "OnQueryActivate" we want to use this one.

We must decide at runtime wether a node is "activalible" or not. I hope you understand me? A Delphi-code snippet or a example would be very usefull.

Thank you.

Best regards

Frank.

Hi,

I guess, now I understand you, and I guess, you have some flag in server to detect if document is saved or not.
As I said before, there is no way to send the response from delphi event..

I suggest you, block the whole tree (Enable/Disable), and then enable the tree when document is saved.

Best Regards.
