I have a DataGridView, and I want to fill in some values in some fields automatically, ie, the form should enter those values by itself when a new row is added. To read the values from a row in the DataGridView, I was using the snippet below:[code]However, I can't use that method to write values. I would have used an update statement, but I actually cant use an update here, because I wanna fill in a few columns of the DataGrid, while leaving the rest for the user to fill in.Better still, is there some way to directly enter the values for a few columns in the bindingsource, and display only a few columns to be entered in the DataGridView? Basically, I have a PatientID field which must be entered automatically by the form, so I wanna leave this column out of the grid to save space. Meanwhile, the other columns, namely DrugID and Quantity must be displayed in the Grid, and the user must be allowed to edit them.
How can i send a table values into DataGridView? I am using Access Database.And one more thing i want to know that.Before sending values into Datagridview i need to work 2 or 3 tables and that result should be keep one Temp Table , that TempTable i want send to DataGridView.Here 2 or 3 tables work means i want to applay leftjoin between two tables and coming result should be keep one temptable and again i want to right join with temptable to other table.This Concept i recently worked on VB, now i want to do work on VB.NET.Is there any way to handel this task? Any i how i am sending Code which i implemented same concept in VB.[code]Here in VB code i used Functions, i called Functions in the FORM and i declared the Functions in the Module. By using Funtions and Recordset i did job. But how can i handle in VB.NET?
The data from field dInc_part is not displaying on the datagrid which has column header. But it display on the new datagrid wherein there is no column or rows yet.
Here is my codes :

Currently I have DataGridView box, clicking generate button fills it with a query from the database.I want the add button to add another row filled using the same query, so far I cannot get it to do it.Current generate button code:
Me.TableAdapter.FillBy1(Me.DataSet.App)
Add button code:
Me.DataSet.App.Rows.Add() - this does add a new empty row
I tried sticking the generate code inside (between add brackets) it but that just did the same thing as the generate code.
Basically I would like to have an sql statement which selects all the bookings from a table in microsoft access callled tblBookings where a certain date (selected by a datetimepicker) selected in vb.net.
The field the date is in access is bookingsdate and that is a shortdate aswell.
The problem is that even if the dates are the same the headers come up in the datagridview but no data.
This is my code: Dim con As New OleDb.OleDbConnection Dim OleDBCon As System.Data.OleDb.OleDbConnection Dim ds As New DataSet

I'm familiar with SQL to an extent from PHP, but I've never worked with databases in VB.net before.I'm making a scheduling system to try and learn how to work with databases, and I have an Access database, that is already populated with data, has all the foreign keys and associative tables, that I need to connect to a DataGridView in my Windows Form.This is basically what I need to accomplish:-Have each table of the database display in it's own DataGridView.-Have changes made in the DataGridView/Windows Form in general... actually update the Access database(I would for example, schedule a new course(by clicking new course, and then selecting the appropriate values for each field), and it would check the make sure the student isn't in a class at that time, that the classroom isn't taken already, and the the instructor isn't busy at that time on that day)
I have a datagridview in my vb.net form displaying data from ms access file A , table A , is it possible for me to export the data in the data gridview to ms access file A table B?? i'm not using sql.
I am trying to implement datagridview using b.net and ms access.While I import the data from database, the connection is established and test connection succeeds. But, during the last phase, i get an error saying :

I am happy that there is a forum like this with very supportive people.So on topic.I am a student creating an Inventory System software for my school using VB on VS 2008.I am having trouble saving items from a DataGridView to Access 2007.The codes I browsed here are quite different from what instructors teach us at our school.These are some of the codes we are using to save items from textboxes to Access 2007 database with a table named studenttable and database named student for your added information.
I have a little problem with converting data from a datagridview to my access 2007 atabase.t's been some years since the last time I've opened Visual Studio 2008. So, probably it's something easyo do.
This is my code so far: Dim i As Byte = 0 While i <> dgInput.Rows.Count
I am working on this program and need read info from an access database to a DataGridView. Now that part i can do. the part i cannot do, and the code i dont know what it is, is to save or update the newly edited data to the access file.
I'm using access as my database and vb .net 2008.My problem is i change a field into 2 ecimal places and when i debug my program why my data in the datagridview not a 2 decimalExample : in access TotalCost = 200.00in vb form datagridview TotalCost = 200
Visual Studio 2010 with Provider=Microsoft.ACE.OLEDB.12.0 ConnectionI have tried multiple ways to do this fought through Concurrency issuescurrent code gives no errors however when I re Fill DataSet nothing has been removed from database...
Current code for Button1(reload data), Button2(delete row): Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
If you remove the AcceptChanges I get a concurrency violation for Deleted row information cannot be accessed through the row.
I have a table in Access called 'tblRealTime' with a few rows of data and I want to display it in a DataGridView object on my form. When I run the program I get no errors but nothing shows up in the datagrid. My code is below:
vb.net Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ConnString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|K0201227Project.accdb;Persist Security Info=False;"
I am trying to learn my way around VB.NET after working in other languages including VB6.I am trying to display an Access table with a DATAGRIDVIEW. All I get is a blank grid. Can someone help me fix my code? I've been playing with this for a while and don't really know what I'm doing with .NET well enough to find the problem. [code]
What I'm looking for is a snippet on how to export data from a datagridview to an access DB. My other question is fairly simple what code would I use once the data has been entered to account for the addition/subtraction. I know these are fairly simple questions with probably incredibly easy answers, but once again the first time I've picked up a programing language was a week ago. Hey trial by fire works 70% of the time all the time.

I have Access database that I am connecting to as such:
Public dbE As DAO.DBEngine Public db As DAO.Database Public sql As String
[Code]....
While I can query for certain data, I want to know how to show a whole table in DataGridView. For example, I have a table called phoneNumbers and I want to show the whole thing in DataGridView3 instead of parts of it.
I have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.
I try this function to insert datagrideview into Access Database but there is an error in insert {"Syntax error in INSERT INTO statement."}
I try insert each rows into Database Public Function SDG(ByVal DG As DataGridView) Dim rows As Integer = DG.RowCount Dim Column As Integer = DG.ColumnCount Dim Product As String Dim N As Integer
I've set up a datasource that binds each table in my access database to the appropriate datagridview... how would I go about submitting changes in the datagridview to the database itself?
ALSO: I would like to have buttons on the form that submit SQL statements to the database and update it. For example, something simple like...when I click the button, it takes the values in the text boxes and forms an SQL statement to create a new record in the appropriate table.... How would I go about submitting SQL via a button?
i created 20 tables in ms access.. and only one table is connected to vb 2008 using the DataGridView?.. how can put the remaining tables in ms access to the vb 2008?
I have an application in which I have to populate a datagridview from one table from an access database. Here is the code that I use to open and close .mdb file.
Public sql As String
[Code]....
... But I don't want to use this way... I want a different way with a dataset or... I don't know.
Does anyone know how to sum fields in ms access using SQL and then place it in datagridview? I have a ms access table with fields 'Points' and 'FacultyID'. I would like to know how to sum all values on 'Points' field and place it in datagridview. Also, I would like to know how to filter values from 'Points' based on selected 'FacultyID'.
