Web Forms :: Reference Controls Between Content Pages?
Jan 12, 2010
I'm starting to play around with MasterPages in VB.NET 2005, and have run into a problem. The idea is to present a Content page with a DropDownList that has some values in it, have the user select one, then navigate to the next Content page. The resulting Content page will then display some information based on whatever value the user chose on the initial Content page.
I had done something similar to this a year or two ago (but using C# 2005, without MasterPages, and the control was a ListBox not a DropDownList) and the way I did it then was to set up an object in the Next page, then assign that the result of (ListBox)Page.PreviousPage.FindControls("ControlName"); from there I could dink around with the 'local' copy of the object and its values. So now I'm trying to do this in VB while implementing a MasterPage, but I get an Object Not Set To An Instance Of An Object error.
The code looks something like this (assume the previous page has a control ID DDLRecordSelect)
[Code]....
I thought maybe it was something funky with the ViewState so I tried it with a TextBox that had a hard-coded value, and got the same result. Am I approaching this the wrong way entirely, or is there hope? I would prefer to NOT use QueryString to pass variables between pages, because IIRC I had to use this local copy of the object business before because the ListBox results were too lengthy.
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 a nested master page. A parent master page, a child master page and a content page whose master page is the child master page. I have a reference to jQuery in the parent master page in the head section.<script type="text/javascript" src='<%#ResolveUrl("~/includes/jquery-1.4.2.min.js") %>' ></script> & Page.Header.DataBind(); in the OnLoad event.
I am using jQuery in all the pages including the master pages. However I am getting "Error: $().ready is not a function" in the content page. If I include jQuery reference in the content page it works. Question: If the reference to jQuery is in the master page head section, why aren't the content pages able to use jQuery? When I do view source, the script tag with jQuery is there and it works. The master pages and content page are merged during rendering and sent to the browser as a single html page so I am not sure when master pages are used, jQuery references break.
UPDATE:
When I changed '$.ready(function()' to 'jQuery(document).ready(function($)' it worked! I am not loading any other javascript libraries and I am not using MS Ajax.
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 will be getting data through wcf service coming form commerce server (instead of DB). Data which is coming will be in the form big html content with all html tags or may be a single line sentence. I should display this dynamic data into the placeholder in the content page (master content page). I have been trying but not able to load when the data is in the form of HTML page. html content or may be single lline of senetence.
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.
My requirement was to share master files among diff projects i read this doc [URL] so i use this technique to share msster pages among my diff projects in a soln but i dnt know how to reference such shared master page as if i use such
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.
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'm attempting to set a class on the body tag in my asp.net site which uses a master page and content web forms. I simply want to be able to do this by adding a bodycssclass property (see below) to the content web form page directive.
It works through the solution below but when i attempt to view Default.aspx the Content1 control loses its content.
Here is how I'm doing it. I have a master page with the following content:
Is it possible with ASP.NET Master Pages to create content pages dynamically?That is, I know we can create content dynamically, but the content pages themselves,can those be created programmatically? I want to give my users the ability to define new content pages (i.e. Categories: Sofas, Tables, Lamps, and add/delete as they see fit) through a management panel. The resulting content pages should have proper URL naming, so that they index properly.An example: http://www.example.com/products/Lamps/contentpage.aspx.Is there a demonstration of this somewhere I can view?
I have a web page using MasterPages built in Visual Studio 2010 Pro. Currently, in the Head of my MasterPage file, I have my reference to my jQuery 1.4.2 file. When I go to a content page referencing the MasterPage I don't get any jQuery intellisense support. (Looks like I just get JS support?) What is more frustrating is the lack of Intellisense in my User Controls (.ascx) - It makes sense though since VS has no idea knowing if my UC will be loaded into a MasterPage referencing the jQuery.
My Scripts folder has one file - jquery-1.4.2.min.js
The columns are first name, last name, email address I would like to write a loop that sends an email message to the person if the email address in thir row is not empty.
I am in need for setting content expiration to immediate for certain parts of my website. Basically we want to expire the "shopping" pages but the browsing pages shouldn't expire allowing users the ease of using the back button to browse around. Is there a way to enable it per page, master page, folder, or something?
The pages on my project are base on master and content pages...
I want to do something with javascript(rather than jquery) in one of content pages after ALL OF MASTER AND CONTENT ELEMENTS ARE LOADED COMPLETELY.(for example set focus on a RadComboBox Control)
But alert(combo); always returns null.(the $find code is for telerik controls and the upper codes about telerik controls are completely true)To solve this null problem I test the ways shown below:
1-I Removed all of controls from master and content page except RadComboBox Control and null problem disappeared , so i derived the null peoblem is about all of elements of master and content page have not been loaded when
$find("<%= RadcbPersonelCompleteNameInvwNoskhehEdit.ClientID %>"); is fired.
2-so i used $(document).ready(function() { my codes }); instead of onload = onloadOfDocument;
3-at last i test the below code and it works perfectly : <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server"> <script src="../JQuery/jquery-1.4.1.js" language="javascript" type="text/javascript"></script> [code]...
What function of document should i use for doing some javascript codes after all Of MASTER AND CONTENT ELEMENTS are loaded completely?
If I go to a content page on my website and enter some data into a textbox, then BEFORE I move focus from that control I press ENTER on the keyboard, the page_load event registers a postback event which in turn passes control to the Master page's page_load event where another postback=true is registered and THEN control goes to the first button on the Master page which is HOME, and then incorrect processing results. Autopostbacks are set to False on the textboxes. If I do not key data into any textbox and press ENTER on the keyboard, I correctly stay within the form
If I use the mouse or tab to navigate thru the textboxes, fill them in and press the Submit button, everything works fine. I cannot see why entering data into the textboxes triggers this action, and even so, why control does not return but instead gets 'lost' on the Master page.
I'm working on a master page, I right click and add a content page, However now I am missing the code behind. So if I make a default2.aspx there is no default2.cs. I can't figure out what I did, It was functioning perfectly before.
I am attempting to access a textbox control on a master page from a code behind base class but having problems. I have 3 levels of master pages. m1.master is the master page for m2.master which is the master page for m3.master.m3.master has a textbox as shown below
