Adding A TabPanel On A Nested Page From A Master Page?
Feb 3, 2010
I come from a windows dev environment so the web makes me feel like a big dummy.
I am using VS2008, VB.NET, 3.5 Framework, ASP.NET, AjaxControlToolkit.
I have included a screen shot that might help to look at while you read my attempt to explain my issue below!
I just recently discovered in a book here on my desk how to interact with a master page programmatically from a nested master page or a regular aspx child page. The method they describe makes sense and is familar to me because they use Public Properties on the master page to manipulate the GUI and controls on the master page. But since they are public, the child pages can see them and fire them off. Makes sense.
I thought I could use this method to do the opposite of that and have the master page fire off something (say a public property in a nested page) to have it then do some work and update things on that nested page.
For example,
I have a MASTERPAGE.MASTER. Under that, I have a LEFTNAV.MASTER (so its a nested master page). Then, under that I have my default.aspx page.
(I did that so that for some of my regular aspx pages I could just tie them directly to the master page so that they dont have a left navigation page...like for big charts or graphs, etc. Is that the best way for that by the way?)
So on the masterpage, I have just a simple asp.net search textbox and an asp.net search button. When they type something in and click search, I want it to add a tab to the AJAXControlToolkit - TabPanel that I have on the default.aspx page, then some other things such as update a datagridview there with the search results.
I can do all of this except the event firing and scope. I cannot see a way to make a button on the master page up top fire off an event that is on the default.aspx page to make it do what it needs to do.
What I tried doing was creating a public property on my default.aspx page. I have some actual code in the SET to do some GUI manipulation and change some stuff on the page. But on my master page within the search button's click event, I cannot see where to call this public property on the default.aspx page...
i'm trying to add a CSS class to a control in a nested master page.what i usually do with a master page is adding this to the nested page:
[Code]....
after i give id=left_a and runat=server to a control in the master page.but when i tried to do it from a page nested in a nested masterpage, it gives me an error.what i want to do i add a class to a control in the nested master page from the nesting page.
I'm trying to dynamically change the look of my main master page depending on what nested master page that the current content page is using .
So for example.
Main master page = main.master My nested page = nested.master (uses main.master) content page = content.aspx (uses nested.master)
So in the Page_Load event of main.master I want to add a switch statement that will check to see what nested master page is currently being used by content.aspx, or whatever content page is loaded.
So far I have got
protected void Page_Load(object sender, EventArgs e) { string nMaster = //This is the line of code that I am looking for. switch(master) { case "nested.master": //all my logic here. break; } }
Following is the structure of the pages in application
[Code]....
Suppose the user is on ..../paycheck.aspx which is the content page. But when ...../paycheck.aspx loads, "lnkDynamic" properties "Text and PostBackUrl" must be set. Which events should be handled .....
On page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.
All I want to do is access the <body> element from the code-behind of a content page and add a class name to it.
I have a top-level master page with the <body> element in it. Then I have a nested master page which is the master page for the content page. From the code behind of the content page I want to add a class name to the body element. That's all.
I have this in the top-level master:
<body id="bodyNode" runat="server">
I added this to the code-behind for the content page:
I am showing Custom Error in my page.. if somehting happend wrong. but if the same error occured in my subview master page I am not able to show the Custom error page on Entire page its showing me that Error page under subview master page. Please I am attaching the Screen shot. how to show the Error page on entire page if something happend in any where submaster or other page.. Here is the code that I am using in web config file to show custom Error page..
master page I have all the js files and Css files links and I have submaster page for mainmaster page.. sub master page have three tabs each tab has grid control.if something went wrong I can able to show the Custom Error page but its showing me in submaster page.. not in main master page.....but if something hapend any where I need to show CustoM Error page in main master page..
<asp:Content ID="TitleContent1" ContentPlaceHolderID="PageTitlePlaceHolder" runat="Server"> My Page </asp:Content>
This works by placing the content page specific title on the page ("My Page" in this example). Now I want to add a global prefix to the title in my master page for the site name. So I want:
here i wan to call nested master page from my base master page, can it work?
coz when i add new nested master page, it allow me to add and when i show in design of nested masterpage, it will link together,but how i make a button in master page to view the nested master page in master page's contain.
I got a Master page and nested master pages in the subfolders.
Top Level Master page
Second Level Master page inherited Top Level Master page
Third Level Master page inherited Second Level Master page
However, changes (i.e. new images & alt. name) that I made in the Top level master page did not apply to the second or third levels.My webpage has a correct front page but not in the sections. How can i correct this ?
I need to add Meta tags, description and keywords in aspx page. My aspx pages are in master page and I have already added meta tags and description in my Master Page.
 Now I want add in my other pages also so if someone search my site on GOOGLE it should look like same as this:
I got a Master page and nested master pages in the subfolders. Top Level Master page Second Level Master page inherited Top Level Master page Third Level Master page inherited Second Level Master page However, changes (i.e. new images & alt. name) that I made in the Top level master page did not apply to the second or third levels. My webpage has a correct front page but not in the sections.
I have a master page and a nested master page... I am trying to get to a control on the master page however I just cannot seem to figure out how to do it.I thought I might need to add both tags on the page however this didn't seem to work... Could someone me understand what i need to do.
[Code]....
I have found a way to do it in the back end... I am just wondering how it works using these tags.
I have 2 nested master pages, lets call them MP1 and MP2. MP1 is top level, MP2 is level
2. Then I have several content pages. Lets say I have 2 content pages for now CP1 and CP2. Each content page has a form that will have some user input and a SaveData()function that saves the data to a database. Each content page also has a "Save" button that calls the SaveData() function.
MP1 and MP2 have several link buttons. The functionality I need is this: Any time a user clicks on a link button in MP1 or MP2, the SaveData() function of the currently loaded page should be called. This is to save the data even if the user forgets to click the "Save" button before leaving the page.
So far I can do this from the link buttons in MP2. I followed the master pages tutorial # 7
In the .cs file for MP2, I declare:
public event EventHandler SaveData;
then i raise a "SaveData" event any time a link button in MP2 is clicked.in every content page (CP1, CP2 etc.) aspx file, I have Master Type directive to assign the Master Page to MP2.
in CP1, CP2 etc .cs file, i have the following code: protected void Page_PreInit(object sender, EventArgs e) { //wire up the SaveData event from MP2 to Master_SaveData function in this page. Master.SaveData += new EventHandler(Master_SaveData); } private void Master_SaveData(object sender, EventArgs e) { //when the MP2 SaveData event is raised, save the data in this page. SaveData(); }
All of this works fine.Problem is I am not able to do a similar thing from MP1.What I have tried so far is to raise an event in MP1 that is handled in MP2. When the event is handled in MP2, it raises the SaveData event to be handled in the page. The event in MP1 is null and hence never raised.
iam developing master page in that master page panel control is there under another panel control is there second panelcontrol is not visiblemy code like that
I have two master pages: TopLevelMaster and NestedMaster
When my page points to NestedMaster as it's master page, intellisense quits working in the .aspx page.
If I change my page to use TopLevelMaster as it's master page, intellisense works.
No matter what I use as the master I always get a green squiggly underline under the Content control that brings up a tooltip that says "Could not find ContentPlaceHolder1" in the current master page or pages"
TopLevelMaster exists in a different project than NestedMaster and the page.
When I say "intellisense quits working" here is what happens:
If I type something between the Content tags I get no intellisense for asp controls:
Only html controls appear upon typing an open angle bracket here
</asp:Content>
If I instert a div element I can type an opening angle bracket and I see a list of all asp controls. If I choose one and start typing there is no intellisense after that:
<asp:Content ID="Content1" runat="server" etc.., etc..> <div> ASP controls appear but no intellisense other than asp:ControlName </div> </asp:Content>
Opening one or both master pages in the IDE has no effect.
Im developing an admin section for a cms tool and in previous tools i used a master page, which then had a page called verified.aspx. this contained a menu control and then dependant on which menu item they selected loaded a user control into a multiview controlThis works fine accept for some small annoying post back issues (not refreshing data and also the time taken to load the large amount of controls)
I have a master page with 2 content placeholders. Im my verified page (which uses the master), i have a nav menu on the left. Dependant on the item selected fro the nav menu on the left, id like to poplute the content placeholders content with an aspx page (which contains a user control) or just an apsx page
ive seen a couple of articles suggesting iframe, and a couple suggesting nested master pages but i dont believe i can get this to work with nester masters,
I want to add a class and initialize a JS funcion behind my nested masterpage which is being dervised from an other master page. But when I add the following code in the PageLoade event in the code behined of my derived page then it give the folowing error
Exception Details:
System.NullReferenceException: Object reference not set to an instance of an object.
