Does a Winform Framework exist for something similar to ASP.NET Masterpage or MS Access SubForm ?
With MS Access SubForm you can do like ASP.NET Masterpage. It's a huge loss of time with Winform when having to create a lot of complex form. You have to compensate with either Code Generation which create code duplication or do Runtime Dynamic Form which is much more difficult.
I have written methods to override the LoadPageStateFromPersistenceMedium and SavePageStateToPersistenceMedium methods. now the problem is that i am using a masterpage, so how do i maintain using my masterpage and still inherit from System.Web.UI.Page?
Bear in mind that the .vb Code behind the masterpage already inherits System.Web.UI.MasterPage. Anybody know how i can "properly" override these methods in a MasterPage?
I'd like to place a button on a WinForm that will allow the user to access an external website via IE.

It does not control the data that is related to it such as "treatment type" "body part injured" . There must be a way to have a single Inj

I've used IPostBackEventHandler on pages in the past for calling the RaisePostBackEvent in my code behind via javascript.I'm currently working on a project that requires the same functionality but would be pretty cool if I could put it in my MasterPage, I've tried similarly it identically but I'm having no luck, I wonder if someone could point me in the rite direction.[code]It's something I don't really want to do on each and every page that uses that MasterPage.

I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.
I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment

I have some processes that run as a background job, allowing a user to continue to use a page, when the jobs are finished (which can take a few minutes) i want to display a message to the user, the best place to display this would be the masterpage AFAIK (incase they move from page to page on the site) so i have defined a div in the masterpage file.
I am trying to find the best method for displaying the data, at the moment i have a method in the masterpage vb file which polls a database to see if the job(which involves complex logic and some db access) has completed, if it has, it shows a message in the div e.g. "Job 13132 has completed" - which works fine.
The problem is this is not dynamic, and i have to refresh the page to call the function that checks if the processes have finished, how can i use AJAX to deliver this content automatically every 5 seconds?
I have tried using an asp timer with a 5 second tick time but the entire page refreshes on the timer click event every 5 seconds.Protected Sub Timer1_Tick(Byval sender as Object, Byval e As EventArgs)

Is there a way to only refresh the div with the updated message, without a full refresh happening using this code? Or if this is not possible, is there any way to replicate the above function using jQuery and still be able to update the DIV text only if a job as finished?
I have a webpage that is used to modify information in a database. The information is properly pulled from the database and properly displayed in their appropriate text boxes. The problem arises when i change the information and try to resubmit it to be saved. Unfortunately it never takes my edited information and reverts back to the original value that was loaded when the page was loaded.
All of the code has been tested out side of the masterpage and it is working properly so i am under the impression that it has something to do with the use of the masterpage. If my understanding is correct i cannot just do something like me.txtName.text to address an object in the content pages. So here is a snippet of the code and the portion that i am assuming has a problem.
[Code]...
The code shows the two methods that i have used to try and use findcontrol to access the text boxes. Both methods seem to locate the textboxes but once I pass the values to linksUpd it reverts back to the value that was originally loaded into the page and discards all of my changes.
I have masterpage.master.vb where I have properties, such as;

I'm developing an application which requires log in. I'm using Master Pages and a customer Web Control which is my main menu system. The main menu accesses database information to provide notifications and various things, none of which will work unless the user is logged in. I am trying to place the following code:
If Session("hgAdminUser") = "" And InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then _
Response.Redirect("Login.aspx") ' if userSession is empty, redirect to login page.
Into the top of my MasterPage code behind, but it's still trying to process scripts, the main problem being that it is running the .ascs file which requires Database access, which it can't do without the required parameters from Login. I've tried running it within a Page_PreInit sub, also Page_Load and Page_Init, but in all cases it ignores this (or probably doesn't ignore it, but errors come in before it deals with this) and returns a big fat ERROR due to functions that I don't even want it to be running!! How can I check for a session variable, which if not present cause all other scripts on the page to be ignored and redirect? This is all using VB.NET

My application has a number of different users, currently there are different masterpages set up for them. The idea is for some type of breadcrumb in the system i.e. home > details > ...What is the best approach for this? I think I will need to define the separate paths that each user can have (all the pages they can view) in the Web.sitemap (will have multiple SiteMapPaths) and then add the sitemap control to masterpage and link them to the appropriate SiteMapPath, does this sound like the right way to approach this?
