Web Forms :: Master Page Controls Accessing Controls Inside Content Page And Vice Versa
Jan 26, 2011
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 ShoppingCart UserControl on MasterPage. I have a following functionality: User adds item to the cart. after clicking the button "Complete Sale" in UserControl the page is redirected to "CustomerInfo.aspx" and after filling the Customer information and clicking on submit which is on CustomerInfo.aspx page i want to call the "Complete Sale" click event of UserControl from "Customerinfo.aspx" page.
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.
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 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 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.
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'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 have a codebehind.vb for a master page from which I'm trying to find a hiddenfield in the content page. I was finding it like this without a hitch...
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.
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:
it is very easy to access master page control from content page like
[code]....
but how could i access controls of content page from master page. suppose a textbox there in content page and one button is there in master page. i want that when i will click on master page button then i want to show the text of textbox in the content page in the label of master page. how to achieve it.
I have a problem i am trying to work out the best method with my limited skills. Im using vb.net(VS 2010) I am using a dll for an IFrame , which is call from code behind. On my site I havea masterpage which has two gridviews. ( GrdViewWebBureau is the one i am using for this query) GrdViewWebBureau is contained within an update panel and updated on a timer control trigger. GrdViewWebBureau updates the page with file counts and status from our clients. I can click on any one of the cells and the code behind is fired. What I am trying to do is put an IFrame on the master page and every time a user clicks on the grid, the Iframe is fired up.
I have tested the iframe and vb code behind from a dummy page and it works, however when the Iframe is on the master page it doeant work. What I am tryingh to achieve is that no matter what page a user is on the site, they will be able to click on the GrdViewWebBureau and the iframe will fire with the correct childpage. Each webPage may also have an Iframe as well, so i dont know if it is possible to make the IFrame global and just call that control ?? I have no idea if 1 this is possible with the code i have and 2, if i have the brains to understand the who what why and when.
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.
i have been trying to solve this issue for over a month and i tried many different things
