Theoretically, this should be a simple task and clearly I am just missing something.
The Issue:
I have a web data menu, pretty basic, contains data menu items which some in turn contain items of their own. When created in markup all elements in said menu are set to enabled="false". When the usercontrol runs through it's page_prerender phase a sub routine (VB) is called which enables required elements based on a series of situations. When the controls loads all elements are still not enabled (however imageurl clearly changes which is done in code behind), yet if said usercontrol then performs a postback everything works as it should.
Clearly this is a case where the webdatamenu is not updating the css applied to said elements when the enabled property is being changed. I am wondering if there is some kind of event I could call which would update the css for said control.
Basic Info:
This is for an upgrade from the UltraWeb controls to the non-deprecated controls pages are currently using assembly Infragistics4.Web.v10.3 with this upgrade being with intent to bring ourselves up to date.
Hello Guy,
I have tested this scenario with the latest version using both a WebDataMenu in a usercontrol and a regular form and so far enabling the nodes on PreRender in both cases seems to refresh the styles as needed. Attached is my test sample for your reference. Please feel free to modify it in order to illustrate the behavior and allow me to look into this further.
So Could this be that we are seeing this issue because we are currently stuck on an older version (v10.3)? If so is there a way to at least solve this behavior for now until our upgrade is complete?
We are currently working on upgrading from the deprecated controls in order to upgrade our infragistics version.
Okay Guy, I will not bother you anymore. I will wait until you test the provided sample and update me with more information regarding it.
Ok, so I attempted to create an example of the error for you however in the example I created I cannot reproduce the error, yet it is still happening on our production page. This is the only toolbar we have which requires this functionality
Could you please tell me which browser you are using?
IE11, I have tried it both in and out of compatibility mode. The plain example I attempted to create for you appears to work however the one on our actual site does not. There is an update panel of the page which surrounds the controls. Is it possible this may be the issue for the menu?
In general it is possible that an update panel or the elements in which a control is nested in, to cause an updating issue. I have however tested this scenario with Zdravko's sample and so far the issue does not seem to occur under IE11. Please keep in mind that IE11 is supported only for versions 13.1 and later. Attached is also Zdravko's modified sample for your reference. If the setup of the update panel in your scenario is different I would suggest modifying the sample to check if that makes the issue reproducible.
Do not hesitate to contact me with any updates or questions.
This issue was simply resolved by setting EnableViewState="false"
I have an open ticket with Alan (CAS-133408-B2J6C8) in which I have supplied a working example which reproduces the error. I am currently awaiting his reply.
