How do you call a modalpopupextender(dialog panel) from any web page in the application with asp.net. lets say i have an email button on several pages and want to call the emailpopupextender. how would i do that?
For those having a similar issue here is a good tutorial for the user_control method of ModelPopupExtender How To: ModalPopupExtender as UserControl
Note: From what I've experienced, trying to call MPE in MasterPage from a page in an IFrame doesn't work. If someone has an idea of how to do please post comment or answer.
If you put your popup extender and all supporting stuff within your MasterPage you could then call it from any page that was rendered as the items would already be there.
If you don't want to do a Master Page solution you could create a UserControl for the process and include that on all pages.

Sorry for this pretty simple question: I have a Master Page with a menu located at left, and an update panel inside a ContentPlaceHolder located at right.
When I click a menu item, and use NavigateUrl property, it loades a page in the whole browser screen. How can I make it loades inside a certain region, in this case the update panel?
Thanks in advance
The quick and dirty answer is to use an iframe.
I personally am not a big fan of iframes and would recommend that if you are truly looking for a "load in place" type solution that you research a more client-side solution than ASP.NET WebForms using UpdatePanels, such as jQuery/AJAX/Templating, KnockoutJS, BackboneJS, AngularJS or Ember.js.
As a different option you can convert the aspx page into a UserControl. Then you can load the UserControl in the update panel.
If you also want to have an aspx page you can create a different aspx page that contains that same UserControl.
I am creating a .net website in c#.
The master page contains a fixed footer bar from which you can display 'bookmarks'. I also have a remove function for each bookmark.
Some aspx pages may have a add bookmark/remove bookmark function (a button control) on them.
I use update panels throughout so button controls are always encapsulated by one.
If I add/remove a bookmark from an aspx page, I can trigger an update to the fixed footer panel. A delegate event is triggered in the aspx page which calls a method on the master page to update the fixed footer panel, so everything is sync'd dynamically.
It doesn't seem possible to do the same the other way around. If i remove a bookmark from the fixed footer, I would need to know if the current aspx page was displaying a bookmark control. Pretty much impossible I would have thought, but I'm open to suggestions.
With that in mind the question really is does anyone have a technique that they use to deal with these scenarios, such as calling a full page update or something similar, or is it a case of doing nothing until the next page load/postback?
Thanks in advance.
I have asp.net application and a TabContainer from AjaxControlToolkit on a form. There are 4 tabs, each containing UpdatePanel, hidden button and some custom .ascx (each with it's own javascript file). Buttons are triggers for panels to update the contents and they are triggered from the 'OnClientActiveTabChanged' event of the TabContainer.
This technique is described here and similiar here. It's pretty simple when looking at it.
The only problem I have is that the whole scenario works when used as a separate page but it doesn't seem to work when masterpage is around that page. Suddenly buttons act as full postback controls.
Do you have any idea what's the reason?
Assuming the buttons your referring to are on the master page, I think you'll want to register the master page buttons as update panel triggers.

I've seen code to handle MasterPage events in the content Page, but if I'm loading a UserControl dynamically into the Page, can I handle the event in the UserControl instead?
Basically I have a button on the MasterPage, when it's clicked I need to make the UserControl do something, such as display text or change a value in a form.
Failing that, is it possible to make an event from one dynamically loaded UserControl fire in another on the same page? I could then replace the button in the MasterPage with one in another UserControl
Thanks all.
This is very similar to this stackoverflow question.
The answer to that question should also apply to yours: your Page knows its master and knows its child controls. It can wire-up a handler on the child control to an event on the master page, so the child control can perform necessary functionality when the even occurs on the master page.
I have a masterpage, having same old header, footer and content sections. I have different aspx pages bases on this masterpage. But each aspx contains a web user control.
For ex. MasterPage -> SiteMaster.master,
ASPX -> CreateBid.aspx,
Web Control -> CreateBid.ascx.
I have used validation controls within web controls showing validation summary within the same control.
The problem here is that, the page postbacks even if validation fails. The validation summary is also shown, but page is postbacked.
Could someone help me why this is happening?
Although the page is postbacked, no code is executed. For ex. If i am clicking on Submit button, nothing is submitted, i could see the validation summary or messagebox but the page is refreshed. If i am considering simple aspx without masterpage the validation works perfectly without page refresh.
Thanks for sharing your valuable time.
Hai Raza,
