I'm about to begin a new web project using asp.net 4.0 (EF 2.0). I have a question on row locking...customer is concerned that if employee 1 has a record in edit mode, they want to lock the row and make it uneditable for other users, until employee 1 has saved their changes. A step further is, if employee #2 attempts to edit the locked record, a notification would appear, notifying employee #2 that "Employee #1 John Doe" has the record locked and to contact them.

I have a nested gridview on my page, I have to apply sorting on that grid and wants the header to be locked. Means when I scroll the grid the header should be visible all the time.I have mousehover and onclick event applied on this grid. Whenevr I try to apply some code to fix the header, it results in detaching of header and moves up the screen on every scroll.

I need to have maybe 5 threads running which all use the same DataSet and need to loop through all the rows retrieved but each row must be processed by one thread only (e.g. I don't want row 1 to be processed by thread 1 and thread 3).
I can also use a DataReader if that helps, but I need to dow some locking logic I would have thought.

What I am trying is, whenever user enters his Name and Address into the textbox on the webpage, I am going to displaying it in a Gridview. Now if second member will do the same thing thing the GridView will be updated and his Name and Address will display in second row and likewise for other users.

vs2008 "There are no usable controls in this group. Drag an item onto this text to add it to the toolbox"
the problem is that in my website web forms items can not display all toolbox elements:Standard,data,html and so on.
first, i have tried click right on the toolbox region to choose "reset items" and "reset the toolbox " command , then in the dialog i check the useful controls, surprisingly whole controls is selected in the default way. but nothing change.

I am modifying a rather large ETL package using BIDS. It builds a datawarehouse, so there are many sources and a single destination. There are quite a few data flow tasks, and their connection strings are read into variables from an encrypted source. All the data flow tasks are arranged serially because of variable locking issues - occasionally two DFTs attempt to simultaneously lock the variable and it fails. I realize there are script solutions out there, but I am looking for perhaps a more elegant (easier) solution than to apply scripted solutions to tons of packages over something so trivial.
I came across the "RetainSameConnection" connection property, and I have a hunch this could be the solution. My reasoning is: If there's only one connection to a data source, there should only be one read operation from the variable. At least, it makes sense when SOURCING.As for destinations, I'm not sure if it's a good idea to have data from multiple sources flowing in through a single connection.This is my first week working in ETL so I don't know all the nuances of databases, ETLs, connections, etc.

In the development environment, in SSMSE > MyDatabase > Security > MyUser > Database role membership I have checked db_owner to allow me to build the database.
Now I am copying the database to the production environment I would like to lock the security down tightly. In the past (with classic ASP applications) I have only checked db_datawriter and db_datareader and, in Securables, checked Execute Grant on the stored procedures.
In Database > Securables I add my stored procedures and check Execute/Grant for each of them and click OK. When I return to the securables page the stored procedures are no longer listed.
I have noticed that nothing is listed in Effective Permissions and I think it should list Execute. If this is the problem, how do I add Execute to the Effective Permissions list?

Is this a bug in 2008 or something related to using the Ajax controls?

I've been building a website and using the AJAX toolkit without any issues. Now all of a sudden the scriptmanager on the page is greyed out and the ajax tools are all greyed out. If I open VWD 2005, I can see the tools but scriptmanager is greyed out. In both versions, I am unable toadd an AJAX tool. I've done a repair on 2008 to see

So the code below is called when a user selects Save on an ExtJS popup modal window. This window ONLY contains a combobox. Now, sometimes when a user saves this, and then re-opens it later on, the combobox will appear BEHIND the window all grayed out, unable to get to. Other times, it will be fine and work, and no difference in events happening either time, just complete utter inconsistency.Does anyone know what this could be?
var changeProductOK = function() {
var win = getChangeProductWindow();
if (win.subProductId.getValue() == '') {

I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?

I have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?

I have two tables
Employee Table : ( EmployeeID,EmployeeName,... Etc )
Bonus Table : ( BonusID,EmployeeID,BonusDate,Bonus Reason,... Etc )
I wanted to list the bonuses in a gridview, so i made a query to return list of bonus records and my data access object returns the result set as Bonus business object ( generic collections of bonus BO ). i have bind my gridview with the bonus collection.
now my problem is that collection has the property "EmployeeID" and it will be displayed but instead of showing EmployeeID, i wanted to show Employee Name in that grid. I have a gridview where i want to list the bonus records ( bonus ID, bonus date, bonus description, employee ID) ,
