Triggering a server-side event from a client-side - ASP.NET Discussion Boards

Re: Hidden fields with ajax and master pages

The controls that are causing the updates are all in the content page. The hidden fields are in an update panel with UpdateMode="Always" so it should always postback, though i did get the info from msdn so it may not be accurate. Any other control that can cause a postback is in an update panel with its update mode set to conditional.

So, trying to follow along. You have two UpdatePanels, and you are trying to update controls in one from events in another? Have you added the controls that trigger the update to the triggers collection of the other?

You are correct. No i have not tried that, reading the msdn doc on it didnt make it sound necessary. I have gotten it to work with the 2 values in the session. I can put a function in the masterpage so that it clears out any unnecessary items when the navigation bar is used. Its not the best way, but i'm not sure if its any better or worse than using hidden fields in the html. If you or anyone else has an opinion on that or any insight into a better way i'd love to hear it. Thanks for all your help so far.

Although the controls are available during the postback, the UpdatePanel, call it the refresh panel, knows nothing about the controls in the other UpdatePanel, call it the trigger, and vis versa. Add the trigger control to the Triggers collection of the refresh panel.

I see what you're saying, I made the mistake of assuming msdn was correct. It said it would always go back on any postback sync or async, I figured it was handeled by the script manager or some other automagical thing.

Thanks for the help.

I didn't get your point, If the Update Mode of Update Panel is set to conditional you can call the UpdatePanel.Update() in post back of any other control.

The hidden fields are in an UpdateMode="Always" panel, all the controls that can cause a postback are in an UpdateMode="Conditional" panel. Those panels all 3 or 4 of them work fine, its the controls UpdateMode="always" panel that isnt working properly, but i belive i have it solved w/ 2 values in the session, i know its a bad practice, but i dont know if its much worse than using hidden fields in the html since the data i'm storing there isnt sensitive at all.

Triggering a server-side event from a client-side

Short version
All I need is that, in a ModalPopUp, when the DoubleClick event of a ListItem fires, the click event of my OK button should be executed.

Detail
I have a ModalPopUpExtender, which hosts a user control. The user control has an OK and a Cancel button. Along with that, it has a dynamic ListBox added to it(may be more). So far, I've considered the following possible solutions:

1. Use Ajax.Net. But, I cannot afford to have a WebMethod.
2. Use a ClientScriptCallBack. This will need a lot of JavaScript, since I have made almost every control dynamic.

Is there any other way apart from using an UpdatePanel?

That's easy. Assuming there is a double click event at all ( and if not, you could fake one ), you just hook that up to javascript, which calls the script to fire the OK button.

How I wish it was that easy, unfortunately some browsers disable that ability and even then for some reason it doesn't always work.

You can however you Page.ClientScript.GetPostBackEventReference(Control, String) to do this.

Using the wrong tool for the job is half the fun.

Done that and its working fine.

Are you referring to PageMethods.MethodName()? I don't want to use it since it will make the event a WebMethod.

You want to know that only need to develop similar kind of tab control? If need to develop then you can developed it using Ajax Tab Container very quickly.
