Web Forms :: How To Write The Content Directly To The Place Holder On The Master Page
Feb 15, 2010
I have a master page called SiteMaster.master
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:
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 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.
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 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 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).
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 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.
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?
Just getting started on ASP .NET and I have a question. I've created a user control that is show's an image. Using a place holder I add 5 items of that control. The problem is that in the display it shows me the control's vertically and I want it to be shown horizontally. Just to demonstrate what I mean (the numbers are the user controls been added):It shows:
1 2 3 4 5
I wanted to show: 1 2 3 4 5 I've tried a few thing's such as using a table - but the table expands with the place holder so It didn't make a differences.
I want to have only 1 placeholder on the page and depending on which buttons are pressed, different user controls are dynamically added. To add to the fun of everything, I need to pass in different values for each user control.
I know that in order to have the values passed into the different user controls and bind to a certain list it needs to happen in the Page_Init inside of the .ascx.cs file - aside from that, I am lost.
i want to create a few textbox dynamically in place holder but when i created and click on btn and use findcontrol to retrive input data that created dynamically storing data in db , i will receive an error like this :
Object reference not set to an instance of an object
I am getting this error "Only Content controls are allowed directly in a content page that contains Content controls". I am using a single aspx page and not a separate cs file. Now, to write code inside aspx page, I am using <script> tag. Now, my problem is inside one of the method I have to use <script> tag. Now, when i use that this error comes. Eg
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.
I bought a website a few years ago, hosted with WebHost4Life,. Since their migration their has been nothing but problems with my site, however, I am stuck because I don't have the knowledge to move it, have tried with no success. Anyway, recently I have been getting parser error messages, Webhost fixed them, and then it starts over again. It takes them weeks to get around to it and since its my livelihood, I can't afford for the site to be down for 5 days then running for one day. I've tried to contact the guy that built the site to no avail, he won't answer my emails.
why these parser errors keep happening. This is a recent thing from the past 2 months, never had this before. What can I do to stop it. it looks like the knowledge here is unreal, I'm in awe everytime I read your answers. BTW, heres my lastest parser error:
Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Only Content controls are allowed directly in a content page that contains Content controls. Source Error:
