VS 2010 - Content Page Accessing Event Handlers From Two Different Master Pages
Jul 1, 2013
I have a ASP.NET content page where the master page is set dynamically. Both master pages contain a print button and an associated event handler for the click event of the button. Unfortunately I receive a run-time error when I attempt to dynamically access the event from the master page that was not initially assigned. Below are code snippets:
Page_Load():
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim strPageTitle As String = "Evaluator Data Form - Instructions"
If Page.MasterPageFile.Contains("masEvaluators.master") Then
Dim mp As Evaluators_masEvaluators = CType(Me.Master, Evaluators_masEvaluators)
[code]....
which produces the following error when I load the page and reference the "masStaff.master" master page:
System.InvalidCastException: Unable to cast object of type 'ASP.staff_masstaff_master' to type 'Evaluators_masEvaluators'. at Evaluators_EDF_Instructions.Page_Load....
I can solve the problem by adding a print button to the content page, but that defeats the purpose of using a master page.
Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
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.
how can i add title and meta tags for content pages in a project base on master and content page(dinamically) ?
i used the blow method for master page :
[code]....
and the error is :(in line *)
Error 17 'System.Web.UI.MasterPage' does not contain a definition for 'SetMetaTags' and no extension method 'SetMetaTags' accepting a first argument of type 'System.Web.UI.MasterPage' could be found (are you missing a using directive or an assembly reference?)
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 a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?
I have a few pages in my web application where I would like to be able to use the code-behind of a master file, but not 'inherit' any of the other stuff like asp/html markup etc.
I've done this a bazillion times but today my mind is simply blank and because it is so easy I've no notes on it.
If I set Title="foo" in the <%@ Page directive of my content page, how do I reference it in the code behind of my master page? I need to use it in a Select Case.
I swear, if my head wasn't permanently attached, I'd have lost it somewhere today.
PS. This question is only silly because I'm asking and I should know the answer.
I am using Master page and Content page combination.But how can i access <body> tag and it's event (onload, onunload) of Master page in .aspx page that is not a content page.
I have an asp.net content page which is used inside of a master page (with header, menu and some links). I would like to reuse it in a different context without the master page (to not display the header and menu there), or with an empty master page if this is somehow possible. I don't want to violate DRY principle by taking the whole page and creating a standalone clone of it for obvious reasons. Is this somehow possible ?
I have over 300 content pages to create. Each has some standard styling. I would like to generate these pages, and was just wondering if there is a utility in web developer 2008 express to do so (otherwise I will just build one - but it would be great not having to do so!)
I have some of the methods in the master page,I want to inherit the master page to content page and use its methods...How will be able to do that..Do we have some techniques with inheritence?Please specify the techniques andPlease in C# with Code Behind...
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.
Today I got a strange problem,that is I am unable to access master page controls in its code behind,I am wonder because,I can able to access master page controls in their code behind of other projects/applications's master pages.
I know we can acess like this Label lblText = (Label)this.FindControl("lbluserName"); in that situation but I need to access div controls which are set to run at server.
I have a main master page, say MasterPageMain, and a couple of folders with couple of pages in each folder which act as a child page to that master page - MasterPageMain.
Now, I have about 10 pages in one of the folder which follows a certain pattern and they could really use a nested pages since any change on some parts needs me to change all the pages which is a pain really.
I already added a Nested master page, say NestedMasterPage - which is a child of MasterPageMain
I tried to change one of the page's <%@ Page directive to NestedMasterPage, immediately, there were a lot of errors. plus I dint know where the NestedMasterPage's children content would go.
What do I need to know in order to do this succesfully?
ps: I dint do this initially because I only had 2 pages, and I dint need this at that time, as the project grew, now i see that I should have changed it much earlier..
I am writing a web application which consists of a master page (header / menus) which does not change and content pages. When I do something like click on a button it causes a post back which is correct but this redraws the whole screen and becomes annoying because every post back and the whole screen flickers.
I have a master page with an unordered list that contains items like, Home, Messages etc.
Now I am working on an EditProfile.aspx page and I want the menu to change and have items like Basic Information, Profile Picture etc. Sort of like facebook. What is the best way to accomplish this...
My requirement is to disable a control on Master page when user is on some specific step of asp:wizard control. I am facing 2 challenges,
1. I am not able to disable the control master page by setting its Enabled property as false, this is inspite that I am getting the control object when I do a Master.FindControl("MyControlName").
2. To try and disable the control from JS, I am not able to find a JS event that would get called when a speific tab step get active and loaded.
