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've got the following VERY basic code
[Code]....
this does indeed update my label with the first item in the Author field in my database, but I can't for the life of my figure out how to go the next record when I click a button. Could anyone give me a quick rundown, or a good tutorial on this, I'd rather not use the built in wizards.

there is a tab control system. It relies on only five text boxes, and their bindings change when the tab is changed The relevant information is displayed. However, if I navigate to a different record...You can see that the same information is displayed in the tab control text boxes, and not the employee's details I just selected in the data grid or the navigation. How can I fix this? I'm not sure what's gone wrong here. Here's the code that changes the text boxes upon changing tab...
Private Sub TabCheck()
If TabState = 1 Then
pnlTabs.BackgroundImage = My.Resources.tabs1

I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.

I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.

I have a child form open (frmProfile) and when I click on the Search button on the Toolbar another form is loaded. On the search form is a few text boxes where the user can input different search functions (First Name, Client ID, Last Name, SSN, Male, Female, etc). Also on the form is one DataGridView.
What I need to do is:
1) After double clicking on a row in the dgv, it sends the clientid to the parent form (frmProfile). I actually have this working but looking for improvement.
2) I would like to then click on the Next button on my toolbar and it go to the next record in line.
At the moment, I only have 1 record that comes in out of 9500. Below is the code from the Search Form and the Profile form.
[Code]...
I have my own toolbar with Add. Delete, Previous,Next etc. I disable some depending on the user so I am not interested in the BindingNavigator. What method is used for movenext in code?I could really use some help on this. I have spent way too much time so far but needing to learn the nuts an bolts of 2008

So I am taking a stab at converting a large VBA project I'm working into .NET. It's in VBA right now only because of convenience of a database (MS Access). But having stumbled upon VB 2010 Express, I'm seeing what I can do in .NET to make my project even better.To that end, one trick I am doing in the VBA project involves late binding.[code]To provide a simplified example, lets say I have three classes, clsOne, clsTwo, and clsThree. They are themselves similar, and in .NET, I'm actually reducing the code each has due to proper class inheritance. But I need to understand how to move away from late-binding, which I use in the VBA project.Now reading into VB .NET some, I've come across the 'Of' keyword, and this looks like the holy grail that I've been seeking. Please understand that these example is not actual code, and the issue cannot be solved (as far as I know) by fancy inheritance and overloading/overriding.[code]

Using Binding Navigators to tables in datasets. How are you all managing putting default values into new records? How are you handling "general" row validation before allowing them to save the record? We actually save on the current change event of the BN right now - client does not want to use a save button. But still how would you "stop" the current change from happening if the record was not yet valid enough (like filling a couple of foreign key fields)?

Why would this code - that loads lots of VENDORS into this dataset - only show "1 of (1)" on the binding navigator?
VendorBS is the BINDING SOURCE.
Private Sub vendorLoad()
Dim connectString As String = "Server=fps-lap-szsqlexpress; Initial Catalog=Casefiles; Integrated Security=SSPI"

I need to move to a specific record. BindingSoucre has MoveFirst, Last, Next and Previuos. It has Find but you can't specify which field to Find in.
What I need is something like the Filter except I just need to move to a particular record based on the value of the primary key.

I'm using VS2010 with a mdb database. I would like to open a new form and fill it with the last added data in the database. I tried to use the "BindingNavigatorMoveLastItem" from the tooltip toolbar but i can't get this to work.
Is there anyone that can tell me the easy way to move to the last record in the database?

i am fairly new to VB.Net programming having been a VB6 developer for years (the copmany i used to work form maintained VB6 apps)?I am writing a new application. I have created my form, databindings to the fields and everything works ok.
In order to filter through the dataset i have decided to use BindingContexManager. I have tried currency manager also.The problem i am incurring is that when i click button next it goes forward 3 records then loops back to the first record again. If i skip to the end of the dataset i can browse back 26 records before it loops back ot the first record and gets stuck in a loop.

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.

Data binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?

I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

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)
