I have a FormView which I would like to open in insert mode only if the form contains no data. I've tried the following if statement:
If True Then
If SomeFormView.DataItemCount = 0 Then
SomeFormView.ChangeMode(FormViewMode.Insert)
[Code]....
but it opens in insert whether empty or not?
I have been struggling with getting FormViews to work the way Microsoft expects me to for about a day and have figure a bunch of great stuff out.
I can catch e.Exception and e.ReturnValue in the ObjectDataSource.Inserting Event Handler and I can even cheat and check other properties of the Object in the ObjectDataSource.ObjectDisposing by checking the e.ObjectInstance ... and I even learned that FormView's Inserting Handler Runs AFTER the ObjectDisposing Handler so If there is a problem found I still have time to react to it and st the e.KeepInInsertMode to true on the FormView.
My problem is, it seems that the values entered by the user into the Insert form are cleared regardless.
So, How do I Prevent a FormView from clearing after it's Insert Method has fired?
(Using ASP.NET + VB)
I don't think posting my code here will really do much good and i would have to modify it to trim out confidential business logic stuff... so I'll skip it for now.
edit:
I have found a temporary and admittedly terribly cludgy solution (in case no one ever finds a REAL solution to the problem).
I have a page variable defined as:
Dim eInsertArgs As FormViewInsertedEventArgs
And then I do the following in my ItemInserted handler
If boolInsertErrorOccurred = False Then
e.KeepInInsertMode = True
eInsertArgs = e

The effect of this is that I am setting the values BACK to the submitted values AFTER ASP.NET binds the FormView to the default (blank) Template.
What is the real mode , protected mode , supervisor mode and the hypervisor mode ?

Why would a .sln solution file open and appear empty in Microsoft Visual Basic 2010 Express - i.e. no windows showing projects and code files etc.When I inspect the file in a text editor, it contains references to vbproj files (which are present) which indicate that it should not appear as empty.No error messages are reported when the file is opened.

View 6 RepliesI am using Visual studio express 2008. I was working on a VB project for a few hours. Then I did something,(I think I just double clicked the form ) and I cannot open it in design mode. By Design mode I mean so you can see the controls, and ad buttons and stuff. The form still runs, if I run it. I see the form in the Solution explorer. From solution explorer, if I show all Files , then open FrmMain.Designer.vb, I can see my code. If I go to the project menu item and insert New Windows Form the new form works like I expect it too, I can see it. I need to be able to see my form.

View 1 RepliesI have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into SQL it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction?
Here is the required part of the code, if you require more just let me know.
Dim rdr As SqlDataReader
Dim cmdInsert As SqlCommand = New SqlCommand()
cmdInsert.CommandText = "spPersonalDetailsInsert"
[Code].....
So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL. What does an empty form field equal? in classic ASP it was always "".
I am trying to save a new object to the database using petapoco.I have an object that uses a Guid for the primary key.Here is an example of the objects primary key property.
<PetaPoco.Column()> _
Public ReadOnly Property Primkey() As Guid Implements IStandardDocument.Primkey
Get
[code]....
Here is an example of the save method.
database.Save("Reservations", "Primkey", reservation)
The sql that is generated is an update with a primkey of 00000000-0000-0000-0000-000000000000 instead of an insert. So new records are never inserted.If I have an existing object with a valid guid the update and delete all work correctly.

I work for a shop that maintains a fairly new app. The app still has its fair share of bugs, with numerous tickets coming in daily. The error information we're given with those tickets is not as useful as it might be because the application was compiled in Release mode, which I read is smaller and faster (makes sense).
Are there any ramifications to deploying a .NET application to production that was compiled in Debug mode? I would expect it would be a bit slower, but I've read the difference is nominal. This would assure us that when we get errors on tickets we have line number associated with those errors and this, of course, makes debugging much easier. major red flags that would prevent you from doing this? I'm tasked with researching the possibility.
This is applicable to C# and VB.Net. I am writing a console application, but one aspect of it I want to make representable in a GUI (that being downloads running, with progress bars). is it possible to write a console mode application that can also have a form in it that can be called from code inside the console component?

View 6 RepliesI 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?

I have followed this tutorial for the most part to explain what I am doing. [URL]. What I need to do is figure out the best way to approach to be able to update my formview. I do not understand what the tutorial is trying to explain to me so i tried it the way I have updated a gridview before. But I am receiving "No parameterless constructor defined for this object." I tried to debug and view the callstack but it does not really tell me much.
I have my sql stored procedure to update which when executed works fine. I also have another class in which I reference the application details class.

A) access the bound text box in the form view template? Something like Text1.text=formview1.customername.text (that doesn't work but that's the kinda thing)
B) access the database field in the table that the sqlsource connects to to feed the formview
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.
View 1 RepliesI have this simple code,
Protected Sub grdSearch_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdSearch.SelectedIndexChanged
TimeOff.Where = "UserName=""" & grdSearch.SelectedValue & """"
End Sub
Doing so causes this error, 'UserName' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly. Near simple identifier, line 6, column 1.
The datasource works fine before the where property is set.Update: I found the issue but I still don't get it.Adding it. in the where clause solves the issue. Like this,
TimeOff.Where = "it.UserName=""" & grdSearch.SelectedValue & """"
