Getting The Selected Row From A FormView Bound To ObjectDataSource In The ItemUpdating Event?
Oct 16, 2010
I have to maintain an ASP.net application in VB.Net.There is a page with a FormView bound to a ObjectDataSource.I have to add some business logic on the ItemUpdating event of this FormView.Unfortunately, some the data that I need to add this business logic is not exposed on the FormView user-interface itself, so I can not use FindControl to get the values (I could add the controls, bind them to the fields I need and set their visible property to true, but that's ugly).

With a DataGridView bound to a bindingsource, which is filled by da.fill(ds) . How do I go about deleting selected rows when the UserDeletingRow event is fired? I've used the following code in the event:
Dim dsEmplTran As New DataSet
daEmplTran.Fill(dsEmplTran)
dsEmplTran.Tables(0).Rows(dgvEmplTran.SelectedRows(0).Index).Delete()
Dim cb As New SqlCommandBuilder(daEmplTran)

I'm loopiing through a datagridview and I want to get the selected value in a combobox, not the bound column's value. (I'm putting the contents of the dgv on a Word document.)
For icounter = 0 To Me.ConversationTblDataGridView.RowCount - 1
range.Text = range.Text & Me.ConversationTblDataGridView.Rows(icounter).Cells("PersonID").Value <-- I want to change "Value" so I get the displayed value, not the person's id
range.Text = range.Text & CHR(13)
Next icounter
It will not take .DisplayMember or .SelectedItem and .Selected returns True of False. Can anyone tell me how to get the name that shows in the combo box instead of the id number?

I am using VB.net (FormView and ObjectDataSource) and Sql Server 2005.
I want to get last inserted @@identity in table on FormView1_ItemInserted
Protected Sub FormView1_ItemInserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewInsertedEventArgs) Handles FormView1.ItemInserted
End Sub My issue is that I want to redirect my FormView to readonly mode after FormView1_ItemInserted but for that I need to show the inserted record in readonly mode and that is only possible if I get my last inserted @@identity.

In the form below you see how the initial selected item is the first record of the table.. these controls are bound.. I want to initially show "Select one" in the combo box or nothing at all and the other controls not to be bound until an actual item is selected in the combobox..

Im having a problem getting the selected values of a listbox that is data-bound..
vb.net
Do Until CType(Ctrl, ListBox).SelectedIndices.Count = 0
For Each Index In CType(Ctrl, ListBox).SelectedIndices
[code]....
The error message says... "Operator '&' is not defined for type 'DataRowView' and string " "." And the only way I can get it to work is to pull out the & operator and change that line of code to this.
vb.net
'FROM THIS:
TableData.Miscellaneous += CType(Ctrl, ListBox).SelectedValue & " " 'Errors HERE
[code]....
The SelectedItem text shows up in the controls current state while debugging, correctly.. but after I finish the execution it shows up as "System.Data.DataRowView"?

I have a formview with several data items that works perfectly except for a single parameter that will not update with the rest of them. The formview's datasource updateparameter is set to do nothing so that I can handle the update in codebehind. Every item works fine, except for one parameter ("salesprice") that is missing in the OldValues and NewValues argument of the ItemUpdating event of the formview. The data DOES pull in to the textbox as it should, formatted properly and all.
I've attached the html, SQL (for getLoanData()), and the codebehind.
Why would every parameter exist in the New/OldValue arguments except the "salesprice" parameter? I've tried populating the textbox without the formatstring, and it's still missing. Is there something about a money SQL datatype that might cause a problem?
HTML:
<asp:FormView ID="fvLoanDetails" runat="server" DataKeyNames="orderid"
DataSourceID="sqlLoanDetails" Width="100%">
<ItemTemplate>

I'm using a textbox to supply a filter for the datasouce which is bound to a listbox. It works (mostly) with a few exceptions, one being i was to restrict the height of the listbox to the number of entries (upto a maximum number), so a bit like a combobox (which in effect is what I'm writing). One of the problems is when the number of entries changes there does not seem to be an event raised, although the OnDrawItem is called for the items to be displayed (the displayed ones!) Is there anyway to find out (in a derived listbox) when the number of entries has changed in the datasource?

I have created several WPF User Controls. The lowest level item is 'PostItNote.xaml'. Next, I have a 'NotesGroup.xaml' file that has an ItemsControl bound to a List of PostItNotes. Above that, I have a 'ProgrammerControl.xaml' file. Each ProgrammerControl has a grid with four different NotesGroup user controls on it (and each NotesGroup contains 0-many PostItNotes.
Then, I have my main window. It also has an ItemsControl, bound to a list of Programmers.
So, you end up with a high level visual view of a list of programmers, each programmer has four groups of tickets, each group of tickets has many PostItNotes.
The trouble I'm having, is that I want to respond to a mouse click event in my mainWindow's code behind file.
I can add a MouseClick event into my PostItNote.xaml.vb file and that is getting called when the user clicks a PostItNote, and I can re-raise the event; but I can't seem to get the NotesGroup to listen for that event. I'm not sure if that's even the correct approach.
When the user clicks the PostItNote, I'm going to do a bunch of business-logic type stuff that the PostItNote control doesn't have a reference to/doesn't know about it.

Original project is VB, but did other testing in Web Developer.Essentially, when a project is compiled as x64 in the ".inx64" directory, "Choose a Business Object" ends up being empty.My workaround was to go into the project's properties and change the compile directory from ".inx64" to just ".in".

I am using VS 2010 web application projects
I have an object datasource connetced to a custom object. The data from objectdatasource is displayed
in the Formview. When i try to do the Update. It sends me two empty objects of the class.
This is my objectdatasource

TypeName="CustomDAL" ConflictDetection="CompareAllValues"

I have a form with:
[Code]...
Whenever I change the value of MyTextBox and press MySubmitButton, the select method of MyObjectDataSource is invoked and everything works OK. But if I change the value of any of my check boxes (without changing the value of MyTextBox) and press MySubmitButton, the select method is not invoked, thus the "MyObjectDataSource_Selecting" event doesn't take place and I get the same results as before.
One way I found to work around this was to explicitly invoke MyGridView.DataBind method whenever MySubmitButton was clicked. Is this the best way to handle these type of parameters? What I am afraid is that this may cause the select method to be called twice making the page slower.

building a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.
Namespace SiteMemberShip
Public Class ProfileWrapper
Private FirstName As String
Private MiddleName As String

I am building a three tierd app, and therefore have all my data access methods in a class by itself.This class only calls stored procedures, basically, I need to pass in the following:
1) stored procedure name as string
2) parameters as IDataParameter() -- an array of parameters
3) other fields ( not important to this discussion)
If I use a GridView on my web form and choose an ObjectDataSourceObjectDataSource, and then choose my business object and method, since the method is a call to a stored procedure with a parameter array, I don't know how to pass it values in the IDataParameter format.The Method Signature listed on the wizard is "RunSP(String spname, IDataParameter[] params), returns SqlDataReader" which basically is calling a method called RunSP with two parameters, of which the second parameter is a parameter array for a stored proc.

If I have an ObjectDataSource setup like:
<asp:ObjectDataSource
ID="ObjectDataSource1"
runat="server" [code].....
How do I get the objectdatasource to use the Delete method with the parameter that is not an Employee object? what is the recommended alternative architecture?
Edit:
To clarify, I want to use the method signature on my data/business object as shown above, however if I try to allow an Employee object to be passed into some of the methods using DataObjectTypeName, then I seemingly lose the ability to have some methods take just an integer id for instance.If I do not use the DataObjectTypeName, then I have to place all the method parameters in the ObjectDataSource and change the methods on the data/business object to match, this seems like a bad design choice because as the Employee object changes I will have to update each of these methods.

Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate
1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).
Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.

I have a datagridview(dgProducts) a textbox (txtproductsTotal)
and second textbox (txtAddproducts)
When the user clicks on the selected row in the datagridview it shows the selected row in the txtaddproducts textbox. That works fine.
But I can't seem to get the total of the selected rows into the txtproductstotal textbox which shows the total amounts of the selected rows. I get each selected row as I click on it, and it replaces but not adds to the amount ( cumulative)of the prior selected row.
I do know how to get the row count of the datagridview but that only gives me a total count off all of the amounts ( RetailPrice) in the entire datagridview, not the selected row as I click on them. So my question is how do I get the SelectedRow count and not the row count.[code]...
