Web Forms :: Passing Variables To Child Page From Master Page
Aug 17, 2010
I need to access a variable that is declared in a master page to a child page. I'm using asp.net 2.0 (vb). I'm sure this should be easy and is down to my inexperience with asp.net! A rough guide to my code is below;
MASTER PAGE
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
<script runat="server">
Public UserNumber As Integer = 3
End Sub
</script>
CHILD PAGE
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
I have a web application that uses the master/child page layout you get by default (at least in a VS2010 web project). The Masterpage has a NavigationMenu, each item on that NavigationMenu has a NavigateUrl that looks like "~/Pages/MyPage.aspx". This automatically opens 'MyPage' in the Content of the Masterpage, so that the master page with menu and header etc stays visible.
Now, the client has a guestbook on her old website (I'm basically rebuilding her website, adding the ability for her to upload new content in her browser), and she wants to keep it. This guestbook is from a 'free guestbook' third party website, over which I have no control. It's simply a website in the form [URL] .... which shows the guestbook for a user 'Username'.
In her old website, I was using frames, so the menu on the left side was in a different frame, and I would simply open the third party website in the center frame. That would create the illusion that the guestbook was on her site, while it was actually a completely different website in a separate frame.
In my new website I'm no longer using frames, but the master/child layout as explained. Is it still possible to 'host' or 'embed' this third party website as a 'child' of the master page?
I tried just putting the url to the guestbook in the NavigateUrl of a NavigationMenu item, but that doesn't work, it just navigates to the third party website and doesn't embed it in any way.
In the parent page i'm displaying all the user details and one of the detail is the list of accessible clients in a list box. the clients can be removed or added using the add or remove images next to the list box.
Clicking on the Add image will show you the list of available clients in a new page(child) and also showing currently available clients to the user with checked status.
Let me explain how the available clients for the user is displayed in the child page. In the parent page load on the 'Add' image 'OnClientClick' i'm passing the ClientId of a hidden field in which all the selected clients for a user is stored.
The problem i'm facing here is when i altered the selected clients in the child page and clicking on the OK button will change the value of the listbox in parent page using the clientID of the listbox which i'm passing, but if i once again click the 'Add' button it shows the original values which is stored at the time of parent page load. The problem is i'm not doing any postback here so that the original values registered during 'OnClientClick'of 'Add' button is not altered.
I have a hidden field (hfUnsaved)in my child page . On keypress of my textbox i am setting the value into the hiddenfield using the following javascript function
[Code]....
On load: txtProject.Attributes.Add("onkeypress", "return Click('a');");
On button click i am removing the value from hidden field as follows:
I created one method in master page, I want to use that method in some other page(Child or Content page).I tried this method but No luck, it's not working in Master Page:
public partial class TestMaster : System.Web.UI.MasterPage { public void XXXX() { } }
I have a page with features supplied from both a master page and a child master page.In the content placeholder for the head in both master pages I have supplied the link to the stylesheet for the site.In Design View in VS 2008 the CSS code seems to be functioning correctly.When viewing in a browser the CSS does not appear to be applied at all.
Here is the CSS code for the div elements within the main content placeholder:
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 m designing master page in which, Problem is that although the size of panel is correct in some child page yet the width of the panel incerase in one child page ..
I have a site which has restricted access. Access is controlled via session variables.
There are a lot of pages to the site so I was going to check for the session variable via the page load event in my mater page. However, on certain pages I use the session variable in that pages page load event. This throws an error when the session doesn't exist, but what I want is the master page's page load to fire first.
i have a master page with a tree view. i need to add a query string to the treeview and that value is on the page that uses the master page. all i want is for the treeview to navigate to the right page passing the clientID. so instead of this:
the value is in the txtClientID text box which is NOT on the master page. here is my master page and the page that uses the master page.master page tree view html code:
VS2010/VB/ASP.NET 4.0 If an error occurs in an ASP app you can redirect it to a default page which is defined in the web.config file How can you pass the variables (URL) to the error webpage then to a logfile or sent via an e-mail address?
Example: 404 Error
- Page hosting the link - URL - Search (if applicable)
I have a listbox containing a list of the datas In the child page. Now, if a user selects a multiple number of the items of the listbox, i have to pass all of them through the session.
So, i want to create an array in the child page and pass the values in the session and in the form of an array to the parent page.
I have a site where I am trying to implement a jQuery UI based MessageBox in my master page. Content pages are arranged accoring to business area folders, i.e. '~/Branding/Contracts.aspx'. I find that when I load such a content page, jQuery, which is referenced in the master page as below, does not load. I assume that this is because the browser is requesting 'Branding/Scripts/jQuery What can I do about this? I don't have the 'root' operator in a plain 'script' tag.
But I dont want to add it to the master page because i am using like button on only ONE child page.. is there a way I can tell asp.net to add this line when that particular child page loads?
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.
