Can someone provide the correct code for updating a datagridview in VB.NET 2008? This would be a datagridview that I have created which displays data from an Access database table using a table adapter. Currently it doesn't save updates or save new records. I need to make it save updates and new records.[code]...

I have created what amounts to a progressbar which is launched using a backgroundworker. So all is well the main UI/process is doing its thing and the progressbar is ticking away. What I would like to do is update some text that is in the progressbar. So when the main UI/process finishes one of its tasks I want to update a message in the progressbar. NOT have the progressbar update the main UI/process but rather have the main UI update the progressbar.

VS 2008, SQL Server 2008:I have a formview that holds data about a test.Each test can have many people assigned to run the test.I have 1 table to hold JobNumber (Unique) with all associated data I have a 2nd table to hold JobNumber And AssignedToID to have records for each person assigned to the Job.Right now I have it set up so the user will choose as many AssignedToIDs as they want and it populates a list box. The list box is a bound control. Can I populate the 2nd table with the contents of the list box?On the update of the formview I could loop through the contents of the list box and update the data 1 by 1 but it will be a pain when users remove assignees.

Basically I am trying to update each record with 2 random numbers each time the button was clicked,my problem now is, the system will update the record but the data was wrong. Example, by right all data should be different (randomly string) but for some row it was updated with same data but in randomly, something row1 row2 row3 has exactly same data for column 1 and 2 then row 3 has distinct data, second time, row1 row2 same data row3 ro4 with different data. It is in random sequence. When I add a MsgBox to do testing in the For loop the data was updated correctly with all different data.
I'm trying to speed up my Repeater so that not as much HTML has to be resent via the AJAX UpdatePanel on each call.
So here's what I have (a very much simplified version):
<asp:Repeater ID="rptContactSteps" runat="server">
<ItemTemplate>
<p>Script:<br /><%#mobjSDIT.FormatText(Eval("script"))%></p>
[Code]....
So, when I click 'btnSaveAndCompleteLastStep' I want all the UpdatePanel in 'rptContactSteps' to update. Having the UpdatePanel inside the ItemTemplate should help prevent having to re-load the html/text that populates the Eval("script") & Eval("notes"), since the value of these variables could be very large and over a 3G connection this could be very costly (in time & money).
I though by adding the async trigger it'd work as I have used this type of trigger before, but not when inside the Repeater. Currently the UpdatePanels aren't getting updated at all, except from the one from which the button was pressed.

View 4 Repliesurl...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.
I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

View 5 RepliesI am beginning to work with .NET technology after several years of VB6 and C++ and I want to learn as fast as possible.
My problem is with a DGV. It shows the prices of several store items, and I intend to let the user modify those prices by entering a % in a textbox (radio button states if that % is positive or negative) or by editing cell by cell manually.
As editing prices is kind of sensitive, what I do is loop through the DGV, add or substract the % engtered in the corresponding column and ask for a confirmation after whole DGV loop is done. If user agrees, DB is updated with new values. No problem here.
If user denies (in case he/she made a mistake), I restore grid's DataSource to a copy I made before calculating new percentages and this automatically refreshes my grid to its original state.
The issue is that if a user denies the operation for a 2nd time, this 2nd execution of the code fails at showing the original values, disabling the pseudo-rollback function.
Here is the code:

We are developping an application VB.net 2.0 and SQL 2005. Users are allowed to cancel a reception based on a purchase which may contains many received goods. But, during the process of cancellation, some questions are asked to users such as "Do you want to cancel Good #1".
If yes, delete. Then, "Do you want to cancel Good #2", no, do not delete and one another question (if received item is issued, a process must be made manualy by the user). And, at the end, if all goods were successfully cancelled, we have to cancel the reception itself. But sometime, if an error occurs or some conditions occurs once asked to user in this process, we want to cancel any actions made from the beginning and make it back to his original state. So I thought about Transaction.

View 7 RepliesI'm having a really weird problem with my current project in Visual Basic 2005.To make a long story short, I have an EventHandler subroutine (Clock1_tick) which triggers on the Elapsed event of a Timer (Clock1). Some, but not all, of the code within the subroutine executes correctly. Some of it doesn't execute at all, even though the debugger shows that each line of code is being read.
The overall details of the program aren't really important, but within the program I have a VB class file which can be instanced via the "New" keyword and contains a series of functions, subroutines, and properties... a typical class file. The class file is for managing sound channels..The frmMain includes a status bar with a label to display the program's current status. It also includes a public sub which recieves a string and sets the text of the status bar:
