Web Forms :: Accessing Master Page Control From Class File?
Aug 27, 2010
i have to write this piece of code in almost 10 to 15 content pages. i am just wondering if i can class file as base class for my content pages and write this piece of code in that class.
[Code]....
can somebody guide me how to write the base class for this scenario?
I have an issue with trying to create a Pdf file from my webpage. Basically, everythig involving creating the Pdf (using iTextSharp) is done, and I'm doing this as a File Stream (i.e, I'm saving the Pdf on local machine). Now what I'm trying to do is create it as a Memory Stream (i.e, open the Pdf from the browser). I was able to do this earlier when I wa still at the 1st version of the application, and all of the code behind was incluced in my .aspx.cs file. But now, I've kept the code in the .aspx.cs at a minimum and put the cude in classes and I'm creating onjects of thoses classes from the .aspx.cs
The problem is that the code from creating the Memory Stream is in a class as follows:
[Code]....
As you can imagine, the compiler cannot recognise "Response" as it's in a seperate class instead of in .aspx.cs
I have looked everywhere for how to do this and all I come up with is threads describing how to expose public properties. I have a USER CONTROL in my Master page. It is a search box with a text box and a dropdown for search type (last name, account number, etc) and a search button. When the user clicks the search button, I open a new page that displays the results. How do I pass the values from the USER CONTROL search fields to the new page? I would post code, but I have nothing to post yet since I don't know where to start. I have tried exposing the public property of the user control, but I don't know how to retrieve those values on the results page.
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.
This code occurs on every single page and it works fine, but my problem is I want to put them on a class file and make it available to the entire application. using System.Configuration;............
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.
I need to display a control consistently across a set of pages. So I'm using a MasterPage to do that in ASP.NET/C#. However I also need to programmatically access this control, mostly provide options to view/hide depending on whether the controls checkbox is clicked.
Here is the Source for the MasterPage
<div id="verifyInitial" runat="server"> <asp:CheckBox ID="chkInitialVerify" runat="server" oncheckedchanged="chkInitialVerify_CheckedChanged" /> I agree that my initial data is correct. </div> <div id="verifyContinuous" runat="server"> <asp:CheckBox ID="chkContinuousVerify" runat="server" oncheckedchanged="chkContinuousVerify_CheckedChanged" /> I agree that my continuous data is correct </div>
Now in the code behind I want to perform the following operations. Basically if a person clicks on the checkbox for the initial div box, then the initial box disappears and the continous box shows up. However it seems that the code behind for the MasterPage does not activate whenver I click on the checkbox. Is that just the way MasterPages are designed? I always thought you could do add some sort of control functionality beyond utilizing the Page Load on the Master Page.
I have a master page, sub master page and content page. The master page has a form control which both masters can access by name alone:
Code: <form id="form1" runat="server">
The content page contains a contact form, with the form tags removed as they conflict with the form tags on the master.
What I want to do now is access form1 on the content page so I can change its properties for use in the contact form. I'm not sure if this is how its done in ASP? Anyway, here's how I've tried to:
Code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim f As Control = CType(Master.FindControl("form1"), Control) f.Action = Request.Url.ToString() f.Name = "contactForm" f.Method = IsPostBack End Sub
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
my MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..
Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?
I have a webform which uses a masterpage which in turn inherits from another masterpage.I have a dropdownlist drpCursosIn my javascript code I tried to access the control but with no luck:var combo = document.forms[0]['drpCursos'];combo is nullAfter checking the source code, I changed it to:var combo = document.forms[0]['ctl00_ContentPlaceHolder1_drpCursos'];EDIT: My javascript code is in an external file
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
Long Time didn't contact you . Now I am working with a new site I have a masterPage file in this master page (General.Master)I added a label to tell the user his status whether registered or not. all my pages belong to this master thus all pages have this label displayed in them with the same text. now in some page (Regesteration.aspx) it also belongs to the general master. but I want to change the text of the label in the master page to be some other text. How can I access the property Text of the control (LoginStatusLb) in the (General.Master) to change it only in this certain page
I'm trying to access a <li> tag in my first master page file. I tried FindControl(..) but it allways returns null. Structure: First Master Page (which contains <li id="element" runat="server"> Second Master Page Default.aspx (need to access here) What do I need to do to access the li element?
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 a textbox and a button, and I trying to give the user a search option in the master page. The onClick event of my button is fine, but the textbox.Text property is always empty. I googled a little and fine many articles about accessing the Master from the ContentHolder, but I believe its no my case...
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?
I have a master page that contains the main site navigation and a child master page that contains a secondary menu. I want to set the starting node on the secondary menu based on the selection on the main menu.
I can get the code to work when the menus are on the same page, but when I separate them into their respective master pages, I get an error saying "The name 'SiteMapDataSource2' does not exist in the current context".
I have tried playing around with the FindControl() method, but either it won't work or I'm not getting the syntax right. Most of the information I find is for a child page referencing the master page, but not the other way around.
How can I access the SiteMapDataSource2 control from the master page? If possible, can you include the exact syntax as I am still trying to get the hang of this.
Here is a basic representation of my code, with all of the uncessary stuff stripped out:
I need to be able to access simple page controls like a textbox from my page class. So if I have a simple aspx page with a textbox on it, I'm trying to do something like this. i'm not using codebehind btw:
[Code]....
I thought maybe I could pass a reference to the page into the class, something like:
[Code]....
But that's not working either. How can I access page controls from my class?
