Hi,

for some reason the confirmation popup for deleting dependencies doesn't work. If I select a dependency and press delete, the confirmation popup appears and then disapears immediatly. But the confirmation popup for deleting single tasks works as expected. Can someone tell me, what could be the problem? Thanks.

Regards,
Felix

Hello again,

I think I've found the reason. The popup only dissapears immeditaly if I attach the OnDependencyDelete-Event to the gantt control. Is this the desirable behaviour? I use a custom gantt provider and need the event to force a full postback to show the user an confirmation message after deleting a dependency.

Regards,
Felix

Hi Felix,

Are you using the latest version? Any javascript errors? Also does your custom provider implement the DeleteDependency() method?

Hi Hrsito,

yes I'm using the Q1 2015 telerik version, I'm not getting any javascript errors and my custom provider implements the DeleteDependency() method. But the error must be before the call of the DeleteDepedency()-method because it is not invoked if I delete a dependency. The popup just appears and disappears again.

I have the same problem, when I want to delete dependencies the confirmation popup appears and disappears immediatly, I'm using the event OnDependencyDelete. I'm using the example of a custom gantt with code behind that I saw in this forum.

Hello Bruce,

Could you specify which version of our controls you are currently using. As you can see in the public item, the fix was implemented on 12 October 2015, which means that the behavior should be the proper one in 2015 Q3 SP1.
