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.
I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.
I have a default page which has a content place holder on it...It defaults to the master.aspx page. Anyroad I attempt to put the loginview there but I can't seem to resize it. Is there something I'm doing wrong? I also put an ajax control in the loggedintemplate and I can't seem to resize that properly either.
how to iterate through all the controls in just my Content place holder ? What I'm looking to do is to Enable/Disable all the controls in my Content place holder (WEbControls as well as HTML Controls).
i have one web page (test) and two masterpages (master_1 & master_2).
the test's masterpage is determined by querystring, so far it's working fine. both master pages have a set on links in content place holder area, but is it possible i can hide the content place holder where my links are, from one of the masterpage when my test page loads, because i don't wish to use the links in the masterpage for my test page. i don't want to delete the links either as i'll need them later on.
The master page has a content place holder (ContentPlaceHolderID="MainContent")
I have a default page (default.aspx) with a VB code behind which pulls some data.
What I'd like to be able to do is write my data to that place holder for example:
<b>theData</b>
This is a simplified example of what I'll be doing but the part I can't figure out is how to write the content directly to the place holder on the master page from the code behind of the default the page.
I am wondering if it's possible to work on Content Place Holder window without seeing master page template?
The second problem i've noticed is that when i try to add a table (1 row, 3 columns) to my content place holder and then try to adjust the width of those columns the whole layout of my page is getting messed up to the point that i have to use ctrl+x to go back to previous stage. The master page was very complicated but i finally got it to work and i don't understand why while i manipulate contentplaceholder the layout of the master page is being affected. (only when adjusting tables)I am new to Visual Studio and was wondering of any known standars in that matter.
i have tested this code and it works great separately .. the only difference is on my project i have DIV, tables, TABs and ContentPlaceHolder. not sure if this can make this code not working.. i am not getting any error..but nothing is happening.
Ajax calendar control not working properly with content place holder of Master Page.Most of time Calender Control hides when mouseover with out changing date in content place holder of Master Page.same code works in normal aspx pages.
I've got a number of MasterPages with ContentPlaceHolders. I do not know how much Placeholders are on the MasterPage. Now i want to load Content to the PlaceHolder, id the ContentPlaceHolder exists. When i use the this.Master.FindControl the MasterPage renders and the added Content would not be rendered. See: [URL] Soo I tried two posibilities of adding the content:
[Code]....
Second way:
[Code]....
The first way seems to be the faster way. But which is the "better" way? Would any of this make any problems?
I'm putting together a help page for my web app and figured that rather than the usual 'Help' file stuff, I could put a short video help file along with an explanation.
I have a page with around 12 topics, I'd like the user to be able to click a link and it shows a video clip (either .avi or mov file) on the page. It would be cool if the movie placeholder just showed the link to the movie that was clicked rather than a new page each time.
This is my scenario. I have a couple of content place holders on a Master page which by default are empty.Two of the content place holders are laid out side by side. I'll call one MainContent and the other SidebarContent. What I'd like to see happen is if a child page has content in the SidebarContent, the width of the MainContent should be adjusted accordingly.Is there a way to determine at runtime from the Master page if the calling child page has populated the SidebarContent?How do I go about this, if possible?
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?
I have done master page and some content page..I have put three LABEL(not in inside the Content place holder) in masterpage and l have store some value..in this, the same value i want to use in content page..how to get that masterpage content value.
I have a page that opens inside a MasterPage. Let's call it the ChidPage. Now when I put an ASP:Button on the child page, its event doesn't fire at all (postback isn't done). While LinkButton on the same ChildPage is working just fine. However if I do something like
[Code]....
It works just fine. But still there is No PostBack with this button, the same event when wired with a LinkButton works just fine. I have ASP.NET 2.0.
I currently have three masterpages and content pages in the following hierarchy: One root-level masterpage that displays the final result. Call this "A" Two sibling pages that don't reference each other but contain all the same contentplaceholder elements, just in a different order with different <div>'s surrounding them. Both reference the root-level masterpage. Call these "B1" and "B2". Several content pages that reference one or the other sibling master pages above (not both). Call these "C1" through "C-whatever".
Cn => B1 => A Cm => B2 => A
This hierarchy works fine. Desired Setup What I want to do is add in a new level to this hierarchy (a new master page) between the content pages and the sibling masterpages. Basically so it's like this: One root-level masterpage that displays the final result. Two sibling pages plus a third sibling. Call it B3 A new middle masterpage that dynamically 'chooses' one of the sibling masterpages. The desired behaviour is to pass through the content given by C directly to Bn without modifying it. The only thing D actively does is choose which Bn. Call this new masterpage D. Several content pages that reference the new middle master page instead of the old siblings. The challenge to this is, I'm working within the confines of a rather complex product and I cannot change the original two sibling masterpages (B1 and B2) or content pages (C) in any meaningful way.
I want:
Cn => D => B1 => A Cm => D => B2 => A Ck => D => B3 => A
Essentially, D should "pass through" all it's content to whichever B-level masterpage it chooses. I can't put this logic in the C-level pages. Additional Details All B-level pages have the same content/contentplaceholder tags, just ordered and styled differently. D can be as convoluted as it has to be, so long as it doesn't require modifying C or B. I'm using ASP.Net 2.0
The contentplaceholder's div is inside the tab div to make the jQuery tabs surround the content. Unfortunately, jQuery duplicates all the content of the master page when turning this into real jQuery tabs:
