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 an Access table which has an auto-number primary key. When I add a new record to it I want to be able to get the value of this field.
The relevant code I have is:
dsNewRow.Item("FullName") = NewStudentFields(0)
dsNewRow.Item("FirstName") = NewStudentFields(1)
dsNewRow.Item("LastName") = NewStudentFields(2)
[Code]....
I want to be able to access the value of the primary key immediately after the Update (if that's possible without having to search the dataset for the new record - cumbersome!) or, even better, just before the Update, if that's possible.

View 3 RepliesI am attempting to create a program that opens a file and reads the contents to then display them in a set of four text boxes (e.g. id, firstName, lastName, avg.Salary). it stores the data in an array.
i have done all that i can do, however, i wish to display in a label something similar to this "5/10 (5th record of a total of 10)" meaning the 5th record in the array out of a total of 10 records. i have already done the code to display the total amount of items in the array, that part was simple, but i can't get my head around trying to code something that will display the record that i am currently viewing in the text boxes.
i have a "view previous record" and a "view next record" button that will go through to the next or previous record, in doing so will change the "5/10" records to the next appropriate number, e.g. "5/10" goes to "4/10" if the previous button is pressed (in doing so, obviously the records that are shown in the text boxes will change to the next or previous record)[code]...
I want to display the index number of the selected record in a listview box as it is clicked by the user. I can do it with multiselect set to false and the following call.
Private
Sub ListView1_SelectedIndexChanged(ByVal
sender As System.Object,
ByVal e
As System.EventArgs)
Handles ListView1.SelectedIndexChanged

This works fine except for one thing! after I click OK to the msgbox prompt, the record highlights normally and I click on the next record, and I get an Argument out of range exception error message, where I expected to just get another message with the next record number.
I have a table from a database and i need to display the total number of record and display it in a label.i already have binding navigator but i will not use to display the total number of record in that table. and i will also make that binding navigator invisible.

I am using Visual Studio 2005 (Visual Basic) and MS Access 2003 I am trying to build an application in the lines of the book "Doing Objects in Visual Basic 2005" by Deborah Kurata. So, I have a Data Access Layer (DAL) Class Library that is separated from the business logic layer (business objects) Class Library. I try to add a new business object such as a "Customer" to the Access Database, where the "Customer" table has a PrimaryKey "CustomerID" which is an AutoNumber field. I am successful in writing the values to the database, but I can't figure out how to know the "CustomerID" of a newly added "Customer" so I can populate the business object with the respective values.

I am having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.
