Multiple Windows Authentication options on login after Web App restore

Hi I have a question regarding SharePoint Foundation 2010 and backup / restore jobs... I'm doing nightly farm backups using PowerShell: Add-PsSnapin Microsoft.SharePoint.PowerShell Set-location $home Backup-SPFarm -Directory \\same-server\***** -BackupMethod Differential This morning I decided to try and restore a single web application, just to make sure it works. In Central Administration I selected the latest farm backup and then selected the node for the Web Application and choose restore (using option: Same configuration) because it's the same server. Restore process went fine, no failure messages, and I can see that it has restored the content I deleted for testing. BUT when I enter the site. I'm presented with a Login page (that you would see if you have also configured Forms Authentication for the same zone, which I have not) and the drop down box show two options: "Windows Authentication" and "Windows Authentication". Both let me use windows credentials to login so basically the login page is pointless and it wasn't there before. I should note: The Web Application was and is configured to use Claims Based Authentication and for Windows Authentication: Kerberos. Nothing for forms. Default sign in page. And I was never presented with this redundant login page before the restore. Anyone knows why this could be happening and how to solve it?? Than

ASP.NET 5.0: Multiple logins and login types in default ASP.NET membership provider

What do you think about an ability of having multiple logins and login types to be attached to the same user? Let me explain this by showing how database schema can be re-factored to support this model:Remove [Password], [PasswordSalt] columns from [Users] database tableAdd [Logins] table with one-to-many relationship between [Users] and [Logins] tablesThis will allow one user to have multiple credentials attached to his or her account of different types such as Username&Password, Windows Live ID, Open ID from different providersYou will be able to restrict allowed login types and OpenID providers in web.config So.. do you think it is a good idea to add support of this model into ASP.NET 4.5/5.0 membership service?http://aspnet.codeplex.com/workitem/7149

how to prevent multiple ConnectionOpen-ConnectionClose


Hey Guys.

I'm writing a page that gets info from my database quite often, but on different events.

To demonstrate, There are three buttons- "Adults","Kids", and "babies".

When clicking on "Adults" the code fetches info from the "Adults" table and displays it.

Everything is working well, thing is I'm not sure that the way I implemented it is good enough.

What I did is that on each button click, in the eventhandler a new instance of the connection object is created, with which I open a conneciton, fetch the data, and than close it.

So, if I have 3 buttons- there are three different connection objects, in three differenct eventhandlers, each doing his own Open-Close.

Thing is the page needs to expand to 19 objects (give or take) where not all of them are buttons, each of them should access my datasource-  and I'm pretty sure that 19 times creating a connection object + Open-Close operations for each is the wrong way.

Now, I DONT WANT TO WIRE UP ALL OF THE eventhandlers, since not all of the objects are buttons.

I've heared something that is called a Singelton might work, but I'm not sure what that.

Any idea will be appreicated. Thanks 

Multiple Login Prompts for Intranet


Hi all,

I'm having an issue with specific users when they are attempting to login to our intranet. When they put the  following in the prompt:


They are presented with the authentication prompt 2 or 3 more times. The site is in the trusted group of sites so I don't think it's that. I've logged in with my own account with no issues.

Forgive me if I'm lacking in any more detail but I'm not a developer nor am I nearly as savvy as anyone else on these forums I'm just breaking into the admin functions here as I just started working here. I have no background in sharepoint so any help would be very much appreciated.

If there's more information you need I can see what I can provide. Again, this is occurring on two different users' computers. I've attemped using their logins and pws as well as adding new users as per hosting company. They created new users in AD and had me add them to Sharepoint. No luck.

Thanks in advance!

-- edit

I've tried to read through a number of various solutions provided both through here and on google but they all seem to lead to the trusted sites solution which is not the problem I'm having. I've tried google for other possible solutions but haven't found anything.

I'm almost certain that our sharepoint server is hosted by someone so any sp

Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Multiple Column Dropdownlist for the ASP.NET DataGrid

Based on my previous control "Multiple Column DropDownList for ASP.NET", I received many emails asking for the same control to be used in the DataGrid for web applications. Here we go.. This control can be used as the regular MS DropDownList in the DataGrid and also as a regular dropdownlist. It has all the properties, like DataTextField, DataValueField, DataSource, SelectedIndex etc. The download file contains the samples both in VB.NET and C#. In this sample, I have used the Northwind database of SQL Server.

I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

Multiple Instances of User Control


I have a user control that I place on a page severl times.  When I make a selection on a ddl in one one control the SelectedIndexChanged event fires for all the control on the page for that ddl.  So I get duplication of an insert that I do.  Is there a way to make sure these events are isolated so this doesn't happen.


>>>How to update multiple rows of gidview by one click



I want to add multiple rows of a gridview if the data for multiple fields are same.

Idea for this is that a user may search a record with some parameter e.g. Sector, plot.

For example 15 records being displayed in gridview.

There should be checkbox before every row and if user wants to update Plot and Flat No that is same for 10 rows out of 15 so he will check the rows and update.

For this a dialog box should appear asking for the parameter i.e. Plot and Flat or something else next time may be it will be City or country. Moreover, there is already an Edit button to update records, when user click it another page open for the record to be updated and whatever he wants to update, it updates.

Hope everone understand the scenario.

I don't want to disturb the already provided Edit functionality and want to provide same record to be updated.

Any idea in this regard would be appreciated.
