I'm still somewhat new to ASP, and can't seem to figure out what the issue is.When I update an item in FormView, I need the text of a button to change.I'm using:
Protected Sub fvClientInfo_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewUpdatedEventArgs) Handles fvClientInfo.ItemUpdated
btnEditClient.Text = "Edit"

I have an issue with a data table that I have updated using the datatable.update command.The datatable is bound to the datagridview using dgv.datasource = datatable.I have used INSERT and UPDATE commands and the INSERT command writes the data back to the database ok. However my problem is that it the dgv is not updated with the primary key (ID field) from the database. So when I save a second time, instead of updating it just inserts the data again.

This VB.NET rookie is asking for the support of those with expertise. BACKGROUND: Form1 has a Datagrid, Dataset1 create by drag DB into datagrid. Form2 presents the record selected from the datagrid. Within the LOAD_FORM I search the DB with the Key and place data in Dataset2 (DS created manually)
CHALELNGE Record updated in Form2 is saved in DB fine and when Form2 is closed, record updated does not appear in Form1. I�ve tried the following but no sucess In form1 event Ive got the code to load data into the DS Me.TUSERSTableAdapter.Fill(Me.PTDataSet.TUSERS) FINALLY: What should I do to see the datagrid updated?
I have an array of objects, I find the item by index, assign a value but then looking at the array the item doesn't show the updated value.

I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

I use a List(Of T) (where each T is a custom type with a few members) to keep track of about 500 items that change all the time. The list can be changed from different locations within the program (uses background workers that monitor the list).
Question: Is there some built-in way to prevent the List from being updated from different locations or from different threads at the same time? For example, one thread may remove an item from the list while another location changes one of the members of an item, causing conflict, wrong data and errors. Perhaps there is a standard way in VB.Net (framework) to solve this type of problem?
I use VB2008 (VS2008 Pro) and WinXP SP2.

i can grab the value of an item from a datagridview but i cannot change a label with that value. don't know why it ain't working.this works, the msgbox displays the value i click.
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim row As Integer = DataGridView1.CurrentCell.RowIndex

but this does not work, the label does not get updated.
label23.text = DataGridView1.Item(column, row).Value
could it be because that label is on another tab from the DGV? should i reference the other tab?i tried TabPage2.label23.text = DataGridView1.Item(column, row).Value but of course it's not working.

View 5 RepliesWe are working on an asp.net 2.0 web app that emails users an ical to save to their outlook 2003 calendar. We noticed none of the code to update or delete an item seem to work even though the ical 2.0 spec supports it. We are curious if Outlook 2003 just ignores this?Does Outlook 2007 act differently?We have situations where an event may change or be cancelled which fires off an email notification but the updated ical just adds a new event, it nevers deletes and or moves the original.

View 7 RepliesI dynamically create buttons on a form and use the button text as ids so that I can pass that to an SQL query to pull saved data about that button when necessary, but I also use an image over buttons that have information saved about them. What I need to know is how do I keep the text on the button from appearing when there is an image assigned to that button? By default vb.net shows both the text and the image and no TextImageRelation values allow for the image to take precedence. I tried changing the text color to transparent, but the outline of the text is still visible through the image. Is there anyway to keep the text value as it is but just show the image on the button?

I have an ASP.NET page with a Wizard control containing several steps and about 80 form fields. The data is collected and inserted to a database from the code behind page. I need to set this form up so you can not only insert, but edit a record as well. So I want to databind the fields. I'd rather not use a FormView because then I would have to revise my existing code, since you can't access controls inside a FormView directly. Is there a way to databind the fields without using a FormView?

View 6 RepliesI have a VB.NET form which was generated when I dropped some fields from a data source table onto a form. To add new records using this form you click on a '+' on the toolbar at the top of the form. What I would like to do is make it so this form functions as if the button had been clicked automatically when it is opened. How do I invoke the add new item ('+') function on a form before the user sees it? When you click on the + a -1 appears in the id field which is on the form but I can't figure out how to cause this with code.
