Web Forms :: How To Retrieve A Value From Master Page
Apr 26, 2010
I have a masterpage with dropdownlist and in child page i want the value of that dropdownlist. Postback in childpage hit before selectedindex changed of dropdownlist. what shalll i do?
I have a master page with a form on it. It's a people search form. When the user clicks on the search button it goes to the search results page that uses the same master page. With the code below I get the info off the master of the current page. Howdo I grab that info from the first page? Here's the code:
Imports System Imports System.Web.UI Imports System.Web.UI.WebControls Partial Class mstrIntranet Inherits System.Web.UI.MasterPage Public Property mSearchName() Get Return txtSearchName.tex End Get Set(ByVal value) txtSearchName.text = value End Set End Property
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load txtSearchName.Text = "People Search" End Sub End Class
Search Results Code Behind page:
Partial Class PeopleSearch2 Inherits System.Web.UI.Page Public SearchName As String
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim mpTextbox As TextBox mpTextbox = CType(Master.FindControl("txtSearchName"), TextBox) SearchName = mpTextbox.Text
when I asked recenlty a question about how To retrive a control in a Master Page from Content Page. Many peoples use this code from my Content Page:
Label lbl = this.Master.Page.FindControl("uxLabel") as Label; //Note any server controls defined in the master page could be not be accessible even after a cast is performed, because they could be marked as protected
This approach certainly works, I also realise that is available a strongly-typed solution that doesn't involve casting the Master property.
In my asp.net application I have two master pages with image controls...for loading the logo based on who ever logs in. In the login details table, I have image column where the Images are saved for each and every login. tell me how to load the image from the database.
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'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; } }
I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page. But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?
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 am working on masterPage/sub masterpages, all worked fine until this morning.When I open a .aspx which uses masterpages, in the design view it shows the error message..
I've checked both master pages several times, all tags are matched and visual stuido itself doesn't indicate any errors. Also in debug mode the html page is generated without any problems..
My computer system froze on me, the mouse froze, cntrl-alt-del, did nothing, so I reset it. Did a disk check, and now everything seems fine except for my master Page html code which I was in the middle of editing when it happened. The VB code-behind file is still ok, the designer file still shows ok with all of the controls in it, but I can't get into desgn or source view. It just opens and gives a whole page of hesixecimal code such as as:
I have a question about master page.After i pushed button i would like to change my master page to another master page for that page, is that possible?
Is it possible to inherit a sharepoint master page(as a parent) in another application's master page which will be treated as child (i.e. after integrating that standalone application with the sharepoint application)? I am totally new to Sharepoint..

now for that i have created one page for the list of pages of the application and user list and i am storing them into the database. and then to hide and show the panels i have created the BaseWebPage in my application but here i am not able to get the master page to hide the panel and show only those which are permitted. i dont have much knowledge of BaseWebPage. i am working in framework 2.0 and i have links of all pages that i have shown in a master page in a panel.
I have a 3 level nested master pages and a content page. parent1 is the top parent, parent2 is parent of parent3 and parent3 is the parent of the content page.
I get an error 'Cannot find ContentPlaceHolder xxx...' where xxx is a ContentPlaceholder. It resides in parent2 and content page is trying to fill it.
Can content pages only use their direct parent ContentPlaceHolders or can they also use any of the higher master pages?
How to access controls in master page using javascript? The master page consists of a search textbox, on key down event of the control I call a javascript function writtern inline of the master page. I get the value of entered in textbox in that javascript function. I have tried giving document.getElementById("<%=txtSearch.ClientID %>").value as well as document.getElementById("txtSearch").value. Both display error. I have to access the textbox control from within the master page itself!
I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.
adID is the primary key (Advert) and acts as the foreign key for Student
I have two pages, both of which each have a detailsview in insert mode
what I want to achieve is to create a new record in advert.aspx (e.g. adID = 4), then when item is inserted, redirect to page student.aspx (which a student record is created) where the foreign key is the ID from the advert just created (e.g. student.aspx?adID=4).
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.
