Updating datagrid vb net

hey frnds, Firstly I pick the records from the databse into the Data Grid View, Then I want that If we made changes to the records in the Grid View & Click on Update Button, Changes are Reflected into the Datbase .

Odbc Connection("Driver=; Server=localhost; Database=shreyas; User=root; Password=;") Dim cmd As Odbc. Odbc Data Adapter Dim ds As New Data Set Private Sub Form1_Form Closing(By Val sender As Object, By Val e As System.

When you edit a row and move to another, if an exception is detected (duplicate key for example), a message is shown, the edit glyph is mantained in the edited row and cursor remain on the edited row.

Data Table Public Class Form1 Dim provider As String Dim data File As String Dim conn String As String Dim addstring As String Dim cnn As Ole Db Connection = New Ole Db Connection Dim ds As Data Set = New Data Set Dim da As Ole Db Data Adapter Dim tables As Data Table Collection = ds.

Because the SQLEnumerator does not supporting async calling, I have added delegates to call those methods asynchronously. NET 2.0, Sql Command object supports async calling to the database.

I use this feature to get all tables from the selected database.

In this demo, I presumed that you already have a basic background on how to create a simple database table. Thanks that cmd do not work fine string id = Grid View1. Hi, how to handle exception thrown when Data Adapter. I can catch the exception with a Try but how to cancel the move to a new row and to force user to correct the edited row?What i would obtain is a "SQL Server Management Studio-style". OLEDB.4.0; Data Source=" data File = "C:\Users\hp-2\Documents\Visual Studio 2012\Projects\Delta\Delta.mdb" conn String = provider & data File cnn. Fill(Data ABC) 'reset the datasource from the binding source Me. Data Source = ABCBinding Source 'should redraw with the new data Me. Refresh() You can use a binding source to bind to with your datagridview.

To solve the problem you need to either re-query the database after each insert, or add the item to tables(0) data structure in addition to the Access table after each insert.
