Is it possible to have a thread running "for ever"? even when the browser is closed?
I tried this in my global.asax:
[Code]....
But without result. It works for about 20 seconds and then it stops until a new user opens a page.
First off I'm using VS 2008 C# (3.5 Framework) and Linq2Sql for ORM. I have a gridview that represents a SQL database table. I want a users to be able to double-click the rows and get the edit items then be able to edit them and move on without them committing the changes to the database until the user clicks the save button. I know how to make the gridview work and all, my issue is that currently I'm having to keep session objects for the table data and edit them as opposed to a Linq2SQL datasource (because that seems to always automatically commit the change to the database). Also, I'm having trouble getting the changes in the edit controls to reflect in my session data objects. Does anyone have any great working examples of doing this type of work in a gridview. I know there are a lot, but I don't see any with Linq2SQL and not committing changes to the database immediately. Sorry I'm usually a back system developer, so I'm not a UI guru.

View 4 RepliesI have a DataList that on Update calls a function "DataList1_UpdateCommand" to update the data
OnUpdateCommand="DataList1_UpdateCommand"
It does not actually update the new value typed in. I placed a debug on the line below, but the text in the "FieldBalance" displays the original value and not the updated value, but the web pages does display what I typed in and not the original.
Dim FieldBalance As TextBox = CType(e.Item.FindControl("txtBalance"), TextBox)
Below is the DataList code and the DataList1_UpdateCommand sub

I have a page where I want to let the users vote on displayed items. My customer wants this done with an image and a VOTE FOR THIS link. The link and image are to disappear once the user has voted, and be replaced with the number of votes for that item. I've made the VOTE FOR THIS link a link button. I'm have two problems:
1) the ListView1_ItemCommand code is always excecuted twice, so the vote count is being incremented by two, not one each time someone votes.
2) A page refresh causes the ListView1_ItemCommand code to run (twice) so a page refresh also casts two votes for the item
If it makes a difference, I display one item per page.

I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:

Users(UserID,UserName)
UserToGroup(UserID,GroupID)
Groups(GroupID,GroupName)
So when i click create new user, the UserId along with GroupID(whichever checked) is saved into UserToGroup table.Im relative to this kind of process and hence facing setbacks. Can somebody help in end to end process. From front to DB SP.

when i checked the checkboxes(not all) ,corresponding rows data has to be updating when i click save button which is outside of gridview,Its just same like our gmail delete button.
I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.

I am trying to update the table records by intering a new values in a textbox
and am facing problems in the code of dataset
how could I perform that
[code]....
You should post any code that you are having problems with in the thread (because apparently some people can't open the files attached).
Anyways, you need a TextBox on the page. Then you need to access the Text in the TextBox (using the TextBox.Text property). Once you've got that you should use it to update your database.
The best way to supply this value (that has been provided by the end user) is to use the SqlCommand.Parameters property (if you're using the SqlCommand object).

Depending upon some condition I want to send the mail to the xyz user which will have two links "Accept" and "Reject" in the message body. When the recepient clicks either of the link an update/insert should be performed in the database against a particular record. For this , when I will be sending the mail, I will be requiring to send some unique Id along with the mail depending upon which I will be able to decide which record to update in the database. I am using SQl Server 2008 and C#.net. Does any one know how to implement it in VS 2008.
