Check for session in master page before child page

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :ASP.Net

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.

Does anyone know how I could achieve this?

Accessing controls / events on a master page from child page

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. Please can you look at my code and pass anyt suggestions / help /  solutions. Master Pa

master pages - objection - child page



If I have have a master page with an object defined in the page load

am I able to access that object from within the page load of a child page?

Thanks in advance

document.ready in master and child page


I have developed a website using jquery. Used Master page with child pages. I used document.ready on both master and child page. Now each and every thing is working fine in chrome and internet explorer. But in firefox, only the documnet.ready funciton works file in master page but does not work in child page.

for reference, you can check www.instruments.com.pk. You will see that it works fine in chrome and IE while child content does not load in firefox.

Any help will be appreciated.

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Passing Linq Statement between master and content page


I usually work with windows forms, and am just starting to work with ASP.Net, so appologies if this is a dumb question!

I have a master page which has a search button on it. The results of this are built up using a Linq statement and if there are any results, I want to display the results in a contents page.

On the masterpage, I have the following code:

Private _res

    Public Overridable ReadOnly Property SearchRes()
            Return _res
        End Get
    End Property

 Private Sub DoSearch()
   'some code to get a linq result

    If res.Any Then
            _res = res
            Server.Transfer("SearchResults.aspx", True)
            'no results
            LabelNoRes.Visible = True
        End If
 End Sub

On the SearchResults.aspx page I have this code.

Dim m As pxSite = CType(Page.Master, MasterPage)
        If m.SearchRes IsNot Nothing Then
            Label1.Text = "Results found = " & m.SearchRes.Count
        End If

m.searchRes is always nothing. 

What am I doing wrong here?


Re-positioning an HTML container with javascript onresize with a Master page.


I have an HTML <div> container that I float to the right of a gridview.  When the browser window is maximized, it looks fine.  When minimized, the gridview positions below the floating container and most of the data is pushed off the bottom of the browser - you have to scroll down to see it.

If I position the floating container above the gridview it looks fine in a minimized window, but looks real bad when maximized.

What I want to do is use a javascript: onresize event to re-position the floating container up or down depending on the window.inner.width AND do it with a Master/Content page structure AND do it for only the one page where needed.

I can capture the onresize event and display the window dimensions but haven't figured-out how to do it with a Content page that still uses the Master page.  I think I'm having a very "thick" week...

How to get all the composite controls present in the registered assembly?

Master Pages: Master Your Site Design with Visual Inheritance and Page Templates


Master pages in ASP.NET 2.0 solve a problem many Web developers have been solving on their own with a variety of techniques for years - providing a single master template for an entire site. This article covers the details of master pages, discussing their usage and implementation and how they are a natural evolution of custom techniques developers are using today.

In essence, I am creating Dynamic Checkboxlist controls and adding them to a Panel.  It works well when I do not have a Master Page configure to this webpage. Once I have a masterpage congifured..

Is master page a best alternative for Frame Sets ??


My webpage has one banner with a logo, a vertical menu bar on the left side of the page and a footer . I have 5 other pages which should get loaded when the user select them from the menu bar. what my concern is actually the banner,  menu bar  and the footer should not change when the requested page loads. This definitely can be handled by sets. But I want to know whether there are any other alternatives for frame sets or could master page be helpful for this purpose ????? 

Any help would be appreciative .

Sharepoint 2007 - Wiki site - New Pages Not Inheriting Custom Master Page


I am working on a SP site (MOSS not WSS) which is heavily customised away from the OOTB layout. I need to create a Wiki site, which was going well - I've created a master page which displays the miniconsole (this was not visible with our customised layout), and made it the default master page for the site. This has been applied to the two standard pages that come with the Wiki site, however when a new page is created, it seems to inherit the default.master, rather than my custom master page - thus not showing the miniconsole.

When I have created a new page, I am able to use SharePoint Designer to attach my custom master page to it, which works perfectly, however this will not be a viable option going forward as end-users create their new wiki pages.

How can I get the new pages to inherit my master page when they are created?


Master Page manipulation


I've never worked with ASP.net before this project, and I am struggling a bit.  The website I am updating was written in ASP.net and C#, using a master page.  The master page is simple enough (header section, maincontent section, footer section, and a righcontent section).

What I need to happen...

On one page only, I would like the maincontent section to extend through the rightcontent section.  On this page I will not need the rightcontent section.

What is the easiest way to produce these results?  As of now, I have unused space on the page...and I can't figure out how to utilize the extra white space.  

Please advise.
