Major Issue in UserControls/NamingContainers

[Rainer Friedl]

Hello,

I am using the latest release. It seems, that ContextMenu and ToolTip in NamingContainers are not working as they should, when a control is used several times on a page.

I have the following setup:
UserControls with ContextMenu and ToolTip in it. Both are assinged to other TargetControls (Panels) using the controls ID.

This UserControl is used 1 to many times on a page (portal page using RadDock).

Both, the ContextMenu and Tooltip are only shown in ONE UserControl. Not in the others placed on the page. The ONE is that, which is first added to the page.

This setup worked with the common RadMenu used as ContextMenu and I with older versions of Prometheus.

Can you help with this issue?

Thanks,
Rainer

Me again:

I tried using the ClientId. This worked for both, ContextMenu and ToolTip.

But I had to assign them in code behind. In Markup using TargetControl...="<%=Control.ClientId%>" did not work!

I think there is an issue resolving the correct ClientId from the Control in these controls?

Hello Erjan,

yep, I will baer with you - and thanks for the points.
I am looking forward to the fix.

But I think I got another one:

I update/change the menu during postbacks/ajax update and it seems the following happend:

The post back is initiated and handled by the menu itself:
=> The changes appear to the menu.

The post back is initated by another control (within same Update Panel, conditional update):
=> The changes do not appear/the state is unchanged.

Kind regards,
Rainer

Hi Rainer,

Please, find attached the latest build as promised. Shall you need the dev package, please open a formal support ticket so that I can send it to you.

As per the RadContextMenu making a postback after an Ajax call - this is indeed a known limitation of the control, which solution is still under research.

It is caused by the detachment of RadContextMenu, needed for the proper operation of the control in some scenarios, e.g. having it declared in a scrolled element.

There are two workarounds currently:

• Add a call to re-attach the RadContextMenu right before the postback;
• Disable the detaching of the control.

While the first approach is harder to implement, it is the only possible solution when having the control in a scrolled element. The second approach is an easier one and can be used when the RadContextMenu instance is located on the page. Please, find attached a small page, demonstrating the two approaches.

I hope this helps.
