How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done
Apr 23, 2010
how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

im trying to add a new data source to my visual studio 2010 project. As it stands my project consists of a few windows forms. I plan on making it access a database (made in access, unless this is a problem), and be able to perform pre-set queries, search/sort, and basic delete,add,edit functions. I will hopefully be later adding the function to print reports according to the database entries.However, the problem i am having is that when i go on to data sources, and click add new source, the following happens:3, it asks me which connection i will be using, i click new connection, then in the new connection dialog i choose the following : Microsoft Access Database File (OLE DB), then i browse for the database i made in the 'database file name' box, Then i delete the default username in the log in to database bit, as my database has no protection.

I have downloaded and run the mysql-connector-odbc-5.1.5-win32.msi. The wizard goes through the process but when I go to vs 2008 and try to Add a Data Source or Show Data Sources I get a blank. NOTHING! Just like I had not clicked on the command. There are simply no data sources available in this virgin copy of Visual Studio 2008. I cannot even access an access db!

I'm working on deploying a visual studio 2005 windows application executable with an embedded crystal report using visual basic. It seems to install everything just fine, however, the system dsn isn't being setup.
How do you configure a setup project to setup the system dsn during the installation?

I am studying crystal report with visual studio 2008. I knew OLEDB, ADO.Net And ADO connections etc. But whatever connection that we must assign data sources. I want to non-configured and assign data sources as like data-grid. In the data-grid, we can configure data field name and generate data assignation in runtime. Can I do this for report or not. If I can this, tell me how can I do this.

I have an Access database and I want to view on a datagridview specific rows. For that I used the following :
CasesBindingSource.Filter =
"OfferDate Between #1/1/1997# And #12/31/1997#"
Cases is the table, OfferDate a field of the table wich is DateTime type.
When I use Between operator I get the following error :The expression contains unsupported operator 'Between'.

I have a bit of code that reaches out and grabs a series of rows from SQL Server DB. I perform an inner join to get some related table data. In the process I get returned the user id of the creator of the data. I then want to pass this into a query to get back a full name. I am having no luck figuring out how to do just that. If I use the data visualizer I can see the name I am after, I cannot figure out the call to extract it
Bindingsource1.DataSource = GetData("Select * From PURCHASE_ORDERS WHERE PURCHASE_ORDER_NUMBER =" & REQ_NUM.Text)
.DataSource = Bindingsource1

I have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).

I have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.

Im trying to do bind a dropdown list to a details view but keep getting an error about the dropdown list ID field:
<asp:TemplateField HeaderText="Approval">
<ItemTemplate>
<asp:DropDownList ID="Approved" runat="server" DataValueField="Approved" SelectedValue='<%#Bind("Approved") %>'>
<asp:ListItem Text="Approved" Value="Approved" />
[code]....
The error message as follows:
'Approved' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value
What is the proper way to attach the value of the dropdownlist to my object so that it can be properly created in the database? Most of my searches keep telling me how to bind a dropdownlist to an object data source, but that is not what I need to do. This is a basic drop down list of 2 items that will never change.

I'm working on a VB Winform project using Visual Studio 2008. The form's controls are all bound to a bindng source and a binding navigator which are tied to a dataset class. When the form is displayed, the first record is displayed as well. However, one of the controls (Radio button) is not showing the correct data from the data set. However, if I navigate to the next record and move back to the first, the radio button properly displays the correct information, so it appears the binding source is working the way it is suppose to.

I have inherited an application at work that someone else started creating, right now about 1/2 of it is functional and is in use. My problem is that it is all done in 2.5 ?? and I am trying to step through it all to figure out how it works. I have always created my own binding sources, adapters and data tables.
One of the things I need to do is add a field to the fm_fieldman_master data table. I add the field in the db (SQL Server 2005)table, I come into VS and refresh the datasource, I then add the field to the fm_fieldman_master data table and the Fill,GetDAta() query I go into the designer and create all the attributes for the combo box

I'm creating a gridview using an objectdatasource and it works fine when pulling all records. But when I want to use the selectCountMethod the grid shows no values. I Step through the code and my getInvoices (gets the requested data) returns data and the getInvoicesCount (gets the total record count). But then when I go through the rowdatabound of the gridview there's nothing in there and no data displays. Here is my code to set the objectdatasource. Any reasons why it wouldn't work or something special that needs to be done for getting the selectcount to work? [code]

Custom Object Master-Detail Data Binding
View 2 Replies
Jan 11, 2010
VB 2008 .NET 3.5. I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment.
My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc.
I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment."
In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use.
I have tried a few ideas, but none of them work properly.

I am using LinqPad to learn Linq by querying the NetFlix OData source.Here is the query I got working which is awesome.[code].....
(Pardon all the comments...it is a testament to the fact I am experimenting and that I will change the query for various needs).There are two thing I cannot figure out.First.Let's say I only want to return the first 10 results.Second (and most importantly). I want to filter by a partial string of the genre.Each title contains a Genres collection. I want to show only Genres where the Name contains a certain string (like "Family").Even better filter using Titles where genre.name.contains "firstFilter" AND "secondFilter".Basically, I want to filter by genre(s) and I cannot figure out how to do it since Title contains its own Genres collection and I cannot figure out how to return only title that are in one or more genres of the collection.

Im doing my first project with WinForms, and Im trying to get the DataBinding working. Theres no database in my project, but I'd like to bind some of the TextBoxes to objects' properties. In the other section of this forum (here) I found this line of C# code which does it: textBox2.DataBindings.Add(new Binding("Text", this.myPerson, "LastName"));
my question is can data binding to object properties be set up during design time (without writing code)? If so, how? P.S. I know how I would set up this binding if in WPF, but I'm forced to use WinForms.
