MasterPage And ViewState - Inherit From System.Web.UI.Page?

Sep 15, 2009

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?

Force Every Page To Inherit From A Base Page?

Jan 14, 2011

I have a web app that has a base page.Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights.My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed.On the init of each page I set the properties "Role1Allowed" and "Role2Allowed".[code]Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was?As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it.Is there any way to force them to do this?

C# - Populate A Masterpage Control Which Is Dependent On The Content Page?

Aug 20, 2009

I have a master page called SampleMaster.master and this page contains a Repeater control

The Repeater control will be used to display the relevant tags associated with each content page and the tags will vary between content pages

The data extraction method Tags.GetTags() is working but I do not know the best approach to populate the Repeater control in the master page dependent on what the content page is.

Would the code reside in the masterpage page code behind or the content page code behind?

Invalid Viewstate Error When Posting Back To Same Page

May 24, 2012

I'm having some issues with an Invalid Viewstate error and I can understand why it's happening but I don't know how to fix it so I'm hoping someone can help.

I have a page which is similar to this /story/?id=123 but I'm using a different page to Server.Transfer to this page.

So I've set up /info to Server.TransferRequest("/story/?id=123") and it works fine until the page does a postback to itself.

We have a login form on this page which simply reloads the page but when it does it seems to add /?id=123 onto the end of the URL so it ends up like this /info/?id=123 thus causing an Invalid Viewstate error.

I've already tried adding EnableViewStateMac="false" - this fixes the error but it doesn't log the user in as expected so it does not give the required result.

Is there a better way to redirect to my page other than Server.TransferRequest but still keeping the nice URL? - I don't want to response.redirect if I can avoid it.

Asp.net - Reducing The ViewState Size On A Legacy System?

Jan 21, 2012

I've looked up ways to reduce the ViewState:

Viewstate Optimisations
Strategies for reducing ViewState size in asp.net

However, due to the situation I'm in, I need the quickest and most effective ways to reduce the ViewState size. The legacy system I'm working on is bloated and routinely has a ViewState that's 800Kb+ on multiple postbacks.

For example, I'm pretty sure populating drop down lists with 100+ items on multiple post backs is one of the culprits, correct?

Disabling the ViewStae entirely doesn't appear feasible. It breaks all of the controls, of which there are many, rendering the pages unusable. If this is the best approach, how should I go about handling all the broken controls?

C# - Winform Templating System Like ASP.NET MasterPage Or MS Access SubForm

Aug 2, 2009

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.

Utilize Classes That Inherit The System.Data Name Space?

Mar 9, 2009

I would like to utilize classes that inherit the System.Data name space.Specifically, I would like to have classes CarColumn, CarTable, and CarSet derived from DataColumn, DataTable, and Dataset respectively.I would like to be able to add additional properities to each class. As an example this is how I would like to reference items within the classes:

CarSet.CarTable(0).Columns(0).foo
CarSet.CarTable(0).bar

I know that VB.Net is not capable of Multi-Inheritance.

Using IPostBackEventHandler On A Masterpage

Oct 24, 2011

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.

The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.

Refreshing Data Using AJAX In ASP Masterpage?

Jan 16, 2012

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)

[Code]...

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?
