Solved datagridview insert with windows form

Posted on 2009-05-06

I created a windows form application with a datagridview.  I can delete, update, as well as insert a record.  However, I am running into an issue where I can only add 1 record at a time.  For example if I click on a new row and do an insert, it will only insert that one row.  Is it possible to do a loop so that it would update all rows that's been created?  Another thing is that I also need it to auto-increment the ID to the next highest number. Below is what I have done as far as inserting and auto-increment.
Imports System.Data.SqlClient

Public Class Form1

    Dim myDA As SqlDataAdapter

    Dim myDataSet As DataSet

    Public WithEvents strDETAIL_ID As String

    Dim builder As SqlCommandBuilder

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim con As SqlConnection = New SqlConnection("Data Source=SRVRNAME;persist security info=False;initial catalog=DATABASENAME;UID=sa;PWD=PASSWORD")

        Dim cmd As SqlCommand = New SqlCommand("SELECT * FROM TIME_DETAIL", con)


        myDA = New SqlDataAdapter(cmd)

        'Automatically generate deletecommand, updatecommand, insertcommand

        'Dim builder As SqlCommandBuilder = New SqlCommandBuilder(myDA)

        builder = New SqlCommandBuilder(myDA)

        myDataSet = New DataSet()

        myDA.Fill(myDataSet, "TIME_DETAIL")

        myDataSet.Tables("TIME_DETAIL").Columns("EMP_ID").ColumnMapping = MappingType.Hidden

        myDataSet.Tables("TIME_DETAIL").Columns("TIME_ID").ColumnMapping = MappingType.Hidden

        myDataSet.Tables("TIME_DETAIL").Columns("DETAIL_ID").ReadOnly = True

        dgViewDetail.DataSource = myDataSet.Tables("TIME_DETAIL").DefaultView

 	'Set this to auto-increment, but not working

	myDataSet.Tables("TIME_DETAIL").Columns("DETAIL_ID").AutoIncrement = True


        con = Nothing

    End Sub

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click



        Me.myDA.Update(myDataSet, "TIME_DETAIL")

        Me.myDA.Fill(Me.myDataSet, "TIME_DETAIL")

End Sub

Have you tried specifying the AutoIncrementSeed and AutoIncrementStep?

I tried that, but it starts from 0 and then each time i click it would increment by 1.  Doesn't seem to increment from currentrow or something.  I manage to hardcode an autoincrement using sql query to find max ID and than adding a 1 to it.

Now issue is I can't just Insert.  I need to select all the lines first and then insert new record.  Is there a way to modify below code so that I don't have to select all the new line I create for it to loop and insert one by one?  
Dim i As Integer


            For i = Me.dgViewDetail.SelectedRows.Count - 1 To 0 Step -1

                cmd.CommandText = "INSERT INTO TIME_DETAIL VALUES(" & strID & ", 2, 2, " & _

                                    "'" & dgViewDetail.SelectedRows(i).Cells("START").Value & "', " & _

                                    "'" & dgViewDetail.SelectedRows(i).Cells("END").Value & "', " & _

                                    "'" & dgViewDetail.SelectedRows(i).Cells("JOB_ID").Value & "', " & _

                                    "'" & dgViewDetail.SelectedRows(i).Cells("OPERATION").Value & "', " & _

                                    "'" & dgViewDetail.SelectedRows(i).Cells("PIECE_NO").Value & "', GETDATE())"







            MsgBox("Save Successful.")

        Catch ex As Exception


        End Try

about the auto-increment,  there's some explanations here:

But for the your loop, i can't tell.  I'm not familiar with this.   Some other Experts might help you

Thanks for the help.  Manage to reverse engineer to insert on cell edit leave if there are any data.
