Web Forms :: Update MasterPage Content Via AJAX

Feb 17, 2010

Greetings. I have a master page called 'site.master'. I have a web form called MyForm.aspx that uses site.master. I have a Label control on site.master called "lblMessage". I have an UpdatePanel that contains a Button control called "btnSave". When the Save button is clicked, it updates the database via the data access layer and then should display whether or not the save was successful. I want to set the lblMessage.Text property (on master page) to display this information. I am currently implementing a method that finds the control in the master page and sets its property and this works successfully (verified via debugging), but the problem is that, because the button is in an UpdatePanel, it is not displaying the text for the lblMessage Label on the master page. In short, any ideas on how I can set the Text property of a Label control in a master page via an AJAX call from a button inside an update panel on a content page?

Is There A Better Way To Update Content Via Ajax Web Forms ThanUpdatePanels

Aug 24, 2010

I consider myself very knowledgeable in web UI development, and over the last four years I have learned a lot about ASP.Net Web Forms, but I still haven't figured out a good way to update sections of a page via Ajax. I have done this several different ways which basically involves a user control loaded by some sort of .aspx page or handler. This works well, but not very generically and usually runs into ViewState issues with anything that is even moderately complex.

I would have jumped to UpdatePanel's sooner, but Microsoft's JavaScript code is total crap. Does anyone have any good strategies to load/update/refresh sections of a web form without using UpdatePanels? Or does anyone have any tips with using UpdatePanels to get around some of the front-end code crappy-ness?

Update (clarification)

Here is an example situation of what I am trying to do to be more clear. On our homepage near the bottom of the page we have some tabs with different content. Each tab's content body has different content geared to some different user type. Of the thousands of homepage visitors we get a day maybe a dozen click on any tab.

Despite this data our managers still would like to have the tabs there. Because each tab body has a lot of HTML content in it, I want to load the content of the tab when the tab is clicked. The solution is obviously to use ajax; however, where do you put the HTML/Controls to load the HTML when the tab is clicked.

I could put each tab's content in its own apsx page (e.g./home/tabs1.aspx), but then we couldn't easily embed the content in the page initially if we wanted to. I could put the content in its own user control and create a HttpHandler or page that loads it, but this leads to view state issues on more complex pages.

I could just hard-code the HTML in a function and then set it a literal or return the HTML in a handler when an ajax request calls it. Each of these solutions work. Some are more than others (the third one is terrible separation of concerns, although I have seen it before).

UpdatePanel's provide the best solution thought because they let you put the content in the correct part of the markup with out a separate file. The problem I have with UpdatePanel's is they require you to use Microsoft's javascript library. Are there any solutions that work like UpdatePanel's without using UpdatePanels?

Box on page that has content when loaded, but updates every 30 seconds Big masthead navigation menu's that I would like to load only when a user hovers over a section You have a form that displays in a lightbox when a user click's a link. (this can cause viewstate issues)

C# - Is It Possible To Read The Content Of A Content Place Holder From The Masterpage

Oct 25, 2010

We would like to use a contentPlaceHolder in our pages to set titles. What we would like to do is have the masterpage check the contentPlaceHolder to see if it has content in it. This way we can set up an e-mailer that will tell us what pages that don't have page titles since we have a fairly large site. We also have nested masterpages.

Ajax - Best Way To Do Partial Update Content?

Apr 15, 2010

Initially i was planning to use master page for every page in my application. At the end, i found out every times the page is changed, it reload full page even it have the same master page. I have confused the frameset with the master page. Then, i have 2 in my minds to achieve it by not using master page.

Using iframe and set the attribute to runat server, so that i can change the page in my codebehind.(I preferred to control the page flow in server side)Make every single child page to user control. Then dynamically load it to the panel in codebehind.

Web Forms :: Pulling Value From Masterpage Textbox Into Content Page

Nov 4, 2010

I am having a slight issue with grabbing data from my masterpage into my content page (as a whole).

I have generated a public property for the my textbox and the contentpage can see this public property. But it comes across empty (even from within the masterpage). Now I guess the problem is with the property itself (possibly). It also shows as empty when I response.write it's value to the page.

Even when I call the value of the property in the masterpage it comes across as empty. The way I have this setup is that a textbox named pageTitleField has it's value updated from an iframe. All is working well and the textbox has its value updated correct upon iframe content changes. This is great. Now I just need to pass this textbox value into my content page and then set it as the document title.

see my code thus far.

My MasterPage

[Code]....

My MasterPage CodeFile

[Code]....

My ContentPage

[Code]....

My ContentPage CodeFile

[Code]....

I know the public property is being seen from the content page because if I just do a Response.Write(Master.GrabPageTitle) I see System.Web.UI.WebControls.TextBox appearing as the output of that property. So it appears hat the textbox value is not being captured in the public readonly property.

Web Forms :: Accessing To The Values Of MasterPage From Content Page?

Jan 12, 2010

I have a MasterPage in my project which it contains a FormView and the FormView is databound with a Connection String to a SQL DataBase.

This FormView is selecting users information from Database, when the ContentPage is loading, Im trying to get the information from the FormView of MasterPage and load them in Content Page, but it is not working fine for me.

For Example:

In MasterPage I have a FormView such as follow:

Name: Amir

LastName:Zandi

Username:amirzandi

In ContentPage, I have a Label and I want to get the name from MasterPage and replace it with the text of the Label.

I am doing this at PageLoad of Content Page with the Following Code:

[code]...

At the page load of ContentPage, it says that it could not find the FormView1

but after I refresh the page, it works fine.

is there anyway for me to ask the FormView in MasterPage to DataBind and After that, it retrieves the Data from FormView and place them into the ContentPage.

I also tried: fv.databind() but it is not working.

Web Forms :: Content Page Modifying A Label On The Masterpage?

Feb 16, 2011

I have a label on the master page that is updated by the contents pages. Rather then create a content placeholder that will contain only this label, I was hoping to be able to modify it directly. I have the label called lblYAO on the masterpage, and in the code behind I have

Public Sub DisplayDataFromPage(ByVal message As String)
lblYAO.Text = message
End Sub

I know I can modify the page directive on the content pages, but there is another person who will be adding pages, and this may be a bit much for him. In the content page's code behind, I would like to do something like Page.Master = "something" but I understand I have to explicitly cast it to the appropriate type first? This is as far as the examples I've seen have gotten me. I haven't seen any casting examples.

AJAX :: Refresh Update Panel Content With New Css Styles

Oct 20, 2010

I was working on this last week and took a break from it to 'regroup' and start over. Here is what I'm trying to accomplish.

1. have a web form with dropdowns to allow the user to select font sizes, colors, background image, etc.
2. I want to the form to be updated with the new styles in an update panel.
3. Once the user clicks the apply button, I want the updatepanel to refresh with the new styles.

I tried this by creating an css on the fly, but the updatepanel wasn't picking up the new css without doing a full page refresh, (which we don't want to do). I only want the updatepanel refresh and either use inline styles, a <style> on the web form etc,
