Web Forms :: See All The Content Of The Page In The ContentPlaceHolder?
Jan 14, 2010
i copied the html code from an aspx page from the tag <form> all the way down and paste it in the sorce of aspx page that bind with the MasterPage. now on the design view i need to see all the content of the page in the ContentPlaceHolder. it worked for 2 pages but in the thired page as i paste the html code the ContentPlaceHolder didnt reshaped itself to page size in the design its like spred all over the page. i'm working with visual studio 2005 asp.net c#
I am searching the internet for possible solution for my problem, I have a page that sets the master page at runtime, my problem is how to create a content (asp:Content) control for each of contentplaceholder (that exists at design-time) in each masterpage?? I am looking at AddContentTemplate, but seems not working...
I have a master page which has several ContentPlaceHolders. Not all of them are used by the current content page all the time. During page rendering the master page needs to set a property when a ContentPlaceHolder wasn't used by the current content page. Meaning a ContentPlaceHolder might not be referenced by the content page.What's the best way for the master page to iterate through its ContentPlaceHolders and find out which ones haven't been used by the current content page? Looking for a solution that does not involve any communication from content page to master page.
This works fine when I display the page. However, when I click the language link which causes a postback the content block does not get added to the placeholder, so I get a null reference because those two panels don't exist. I've been pulling my hair out over this for a few hours now and I can't figure it out. In case it helps, here is my InitializeCutlture method:
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
What I'm trying to do is use one master page with two different layouts. Currently we have a "master" master page that has all the common elements and two master pages that use it for the two different layouts. This gives us 3 master pages and there's developer confustion and it is a bit of a hassle to keep them consistent. What I'd like to do instead is say "if there's anything in the MainContent ContentPlaceHolder, show the single column layout, otherwise show the two column layout".
From what I've read you're supposed to be able to do this by using something like the following:
[Code]....
But this.MainContent.Controls.Count retuns zero when the ContentPlaceHolder uses Html.RenderPartial. For example, this works fine:
[Code]....
This causes this.MainContent.Controls.Count to return 1. If I remove MainContent from the view, it returns 0, as expected. However, if I do this:
[Code]....
Then this.MainContent.Controls.Count returns zero.
In my masterpage i have already defined metakeywords and description. But for one of my page i would like to define metakeywords and description which will be for that page only.
The metakeywords and desciption defined in master page is for the website.
Where and How to define metakeywords and desciption for any page which doesn't have <head> tag as it is linked with masterpage.
is it possible to put two different contentPlaceHolder from two different ASPX page in one MasterPage? Just like iFrame? if not what asp.net process/control can?
As the first step, I designed a Master Page for my website. Everything seems to be in order. My master page has a table say "Mytable" with 2 rows.
In the first row, I've put up a banner for the website.
In the second row, I want to place the ContentPlaceHolder.
The thing is that I can't make the ContentPlaceHolder to occupy the whole cell. I tried finding the solution through search engines and could not find out a solution.
In my web page, I want to create a table by Javascript. I mean that I want to make this table to occupy the second row of "Mytable". There is still some gaps left at the top and bottom of the ContentPlaceHolder.
Looking to have a export button in master page. Gridview is placed inside panel, so I couldn't get the gridview to export to excel. I have gridview's wherein I can able to export to excel that are directly placed in maincontent (Content PlaceHolder). The problem is if gridview is placed inside panel I couldn't export.
My project has the following repeater menu shown on the Master Page. I need this menu to remain hidden until the user logs in. How do I access from content page?
I have a masterpage that has a banner and under the banner it has a few links...The issue i am having is when clicking on a link i would like the linked page to appear in the contentplaceholder, i can't seem to figure it out.
I have a asp.net webpage which is using an Master page and contentplaceholder.
My Req: I want to access the control name through javascript.I have tried to use 'document.forms[0].elements[i].name' but its giving an error since my page there is no form.Only master page and contentplaceholder.
I'm incorporating some parts of an old asp application into a newly written mvc app. In most places I've separated out the data access and business logic into the model, and written new view's and viewmodels on the mvc side, although what I ended up with was not perfect, it works reasonably well.There's one area that's probably a bit too much work to do that. It uses an asp treeview and custom controls, and has lot's of code that just isn't partitioned very well. It's one of those 'well I wouldn't start here' situations, but unfortunately it's the code I have. As an application in it's own right it works well and has done for the past 5 years or so. Although it does want re-writing, that's probably more work than I wanted to do right now if I can get away with it.
The asp pages decend from a custom asp page, which itself decends from asppage and contains a custom DAL. What I'd really like to do, is 'paste' the page produced by this legacy asp page into the 'main' contentplaceholder area on an mvc form. I know I can incorporate standard asp pages into an mvc application, but that isn't what I'm trying to do as I want to use the master page from the mvc application.
I am having asp:hyperlinks in my master page, which i use as my page headers. I would just like to change the text format of the hyperlink when a content page is loaded.
the CS code for accessing the master page contents from content page?
I have two master pages in my project, one for web views and another for emails. In the web master page is a placeholder to put page specific JavaScript, if a page is using this and I try to programmatically change the masterpage to send as an email the server falls over as it can't find the placeholder.
Is there a way to change the behaviour so that if a placeholder can't be found it just doesn't include that bit? I'm thinking maybe on my page base class looping over a collection of placeholders and content tags and removing the ones that don't match up, but I'm not sure if there's a good point in the page lifecycle to do this.
I'm using MVC not WebForms if this makes a difference.
I'm designing a website and i want to use 3 columns on the master page,left center and right.I want to create each column with a table so we have table1-left column, table2-center column and table3-right column.On an inherited page i would like to created div's,span's etc.So the question is where exactly do i put the contentplaceholder of the master page?Do i need 3 contentplaceholders one for each table?Also the contentplaceholder would be inside a table a tr or a td?
How to I put this form on my page? The problem is I have a master page which wraps the content pages content in the ASP.net form, I can't nest the forms.
masterpage with a contentPlacholder multiple pages which use this masterpage and implement a base-class (fooPage) fooPage has a certain property (fooProperty)
[Code]....
Obviously this is not going to work - but how can I achieve this?
I know the alternative: call a method from the masterPage in the contentPage with fooProperty as a parameter - but i would like to rather have a pull-system in this case...
I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.
I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.
In master page I am using asp content place holder. And in my child page I am using pure html coding. When I attach master page in my child page I am getting this error.Content controls have to be top-level controls in a content page or a nested master page that references a master page.
Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):
System.Web.HttpException: Content controls are allowed only in content page that references a master page.
This is followed by Stack Trace:
[HttpException (0x80004005): Content controls are allowed only in content page that references a master page.] System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +9744256 System.Web.UI.Page.get_Master() +55 System.Web.UI.Page.ApplyMasterPage() +14 System.Web.UI.Page.PerformPreInit() +51 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1104
I am not using any Content Place Holder or Master Page (does the error refer to the Site.Master file because while I can see it in. Solution Explorer, I never use it. All of my aspx files look like this along the top with no reference to Site.Master:
