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 masterpage and has some linkbuttons in it, i also have a webform which is a content page for the masterpage. i like to access the controls to the webform via the linkbutton residing in the masterpage or access the linkbuttons via the webform controls.
I have a master page with a textbox that I want to use for a search, and display the results on the content page.
I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.
The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.
How do I set this master page search box as the parameter for my datasource?
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)
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.
Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):
System.Web.HttpException: Content controls are allowed only in content page that references a master page.
This is followed by Stack Trace:
[HttpException (0x80004005): Content controls are allowed only in content page that references a master page.] System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +9744256 System.Web.UI.Page.get_Master() +55 System.Web.UI.Page.ApplyMasterPage() +14 System.Web.UI.Page.PerformPreInit() +51 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1104
I am not using any Content Place Holder or Master Page (does the error refer to the Site.Master file because while I can see it in. Solution Explorer, I never use it. All of my aspx files look like this along the top with no reference to Site.Master:
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 :
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?)
In master page I am using asp content place holder. And in my child page I am using pure html coding. When I attach master page in my child page I am getting this error.Content controls have to be top-level controls in a content page or a nested master page that references a master page.
I have a master page homeMaster.aspx and many content pages. However the situation is I have few .html pages. Now when a user clicks on a link the html page should get loaded.inside the master page. The problem is these are .html and not content page with .aspx.
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?
Following is the structure of the pages in application
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 .....

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
Wondering if it is possible to access a master page's hidden field (ex. <Input Type="Hidden" ID="TestHiddenField" Value="testValue"/>) From a Content Page's C# Pack CS Page.If it is possible, How do I go about doing so? I have tried:
PreviousPage.Master.FindControl("[TestHiddenField]") but no .Value attribute and no luck in general.
