VS 2008 - Using SQL Database With DataGridView
Jan 31, 2010
I just want to simply be able to edit a database directly using a Datagridview. That includes adding new rows, editing existing ones, and deleting rows. So far if I have been able to get one of those actions to work, the others do not. I found the codebank entry by JMC and I am trying to use it to connect to my database. I have a bindingsource, a dataset, and tableadapter created via the designer. Now I need to figure out how to combine all these components.
VB.NET
Imports System.Data.SqlClient
Public Class Form1
Private connection As New SqlConnection(My.Settings.Database1ConnectionString)
Private adapter As New SqlDataAdapter("SELECT ID, Name, Quantity, Unit FROM StockItem", connection)
Private table As New DataTable
[Code] .....

I have searched the forums for an answer to my problem, but I have not found any solution.First of all, I know that the datagridview is "supposed" to automatically refresh when new data is entered, but in my case it does not seem to work.
I am using VS2008, with an Access 2007 database. The database has 2 tables, but I am only trying to work with 1 of those tables.For this project I have 3 forms that I am working with. The main form calls a form that has an embedded datagridview for the 1 table in it.
By double clicking on a row, this form hides (Me.Hide()), and the second form appears where the new data is entered for the row selected.
Once the data is saved from the second form, using "Update", the second form hides, bring me back to the main form once again.
If I then click on the button to call up the form with the datagridview, it appears, but not with the new data on it. If I use the "x" button (top right corner) to close this form, and then click on the button to call the form once more, it appears with the correct data.I guess my question comes down to this. Do I need to not use Me.Hide() on this form, and if so, what would I use to make sure that the next time I show the form the data has been updated?

I have an application that saves and loads data to and from a database, via a DataGridView.
Originally, I setup another form that accepts the data and when the "Search" button is pressed, it closes and loads it into the main form's database.
But, my boss doesn't want to do it this way. I actually like this new method better... but I can't get it to work
The DataGridView has 14 columns. The user should be able to fill out 1 or all of the cells and that data should be used to complete the search, which is then populated into the DataGridView.
I have all of that figure out, with the exception of figuring out when to call my search method.
I tried capturing the "Enter" key press in the KeyDown event, but that only works when the DataGridView itself has focus, and not when a row, column, or cell does.
I then tried the RowLeave and RowValidated events, but then I get an exception stating that I can't call that method from those events.

I'm using DataAdaptors to pull data into a DataGridView. I want to make changes to the data via my DataGridView and then update the database when the user clicks the 'Update' button, but I can't figure it out. Below is my code.

I'm writing my first Vb application and have come to a grinding halt... I've created a windows form which has got a datagridview (which is populated by a tableadapter and a dataset generated from a SQL stored procedure) with two columns (Product and Qty), I'm populating the Product Column using a Stored Procedure, the user then adds the quantity. Once they've finished filling everything out they'll then hit a save button and I then need to insert both columns (along with a reference number which I'm getting from a text box) into a table on a sql server.

I'm using a DataGridView in a Windows Forms application to update a table in my SQL CE database. The code runs without error; however, it appears that the database table is not being updated. I had this working at one point, now it is no longer working.
Private Sub BtnCommitChanges_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnCommitChanges.Click
If Me.CLCitiesDataSet.HasChanges = False Then Exit Sub 'Exit sub if no changes to dataset
Dim SQLCommand As New SqlCeCommand("SELECT * FROM Cities")

I had done this by using the query builder (in VS Studio) but soon found out thay I gain no points by doing it this way as I am not using any code. I have tried to adapt the code I had to insert data into my database, just changing the SQL sintaxa and some other bits, but it is not working yet. Well, it gives results, but I think it is still geting the results from the query I had built using the query builder. Here is the code I've got so far:
Public Class Form2
Private Sub btn_search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_search.Click
Dim str_search As String = txt_search.Text
Dim str_dob As String = txt_dob.Text

I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.

I have an application doing the following:
- Treeview with customers
- on clicking a treeview, for every project of this customer, a new MDIchild opens, where the products of this project are displayed
- the MDIchild is basically a DataGridView, which is connected to the products-table via a DataView
my Problem comes after changing a value in the products DataGridView:
- if i do not change the row, the changes will not go back to the database after an update
- if i do change the row after entering a new value, everything works fine
The strange thing is, that in both cases, the value in the DataTable is changed, the DataSet is "hasChanges=True" and the DataRow's state is "Modified".
