showing current record of dataset in datagrid

[digitalsindhx]

Friends I m workin on vb.net ado.net oledb, I have also added datagrid Control to my form

for retriving database from .Mdb file i used following code

'decleared Name Space
Imports System.Data.OleDb


'Dicleared Variabls in Class  Form1 

Dim con As New OleDb.OleDbConnection

    Dim ds As New DataSet
    Dim da As OleDb.OleDbDataAdapter
    Dim sql As String
    Dim inc As Integer
    Dim MaxRows As Integer


'created Navigate Records() 'class
txtSno.Text = ds.Tables("SLAPhonebook").Rows(inc).Item("SNo")
        txtName.Text = ds.Tables("SLAPhonebook").Rows(inc).Item("Name")
        txtLastName.Text = ds.Tables("SLAPhonebook").Rows(inc).Item("LastName")
        txtOrganization.Text = ds.Tables("SLAPhonebook").Rows(inc).Item("Organization")
' and so on...

' on form load () event i put following coding
con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=D:\SLAPhonebook.mdb"
        sql = "Select * From sla"
        da = New OleDb.OleDbDataAdapter(sql, con)
        da.Fill(ds, "SLAPhonebook")
        MaxRows = ds.Tables("SLAPhonebook").Rows.Count
inc = -1


' here i connected all text boxes to '0' row of ds.tables(rows) to show first row, as follows


txtSno.Text = ds.Tables("SLAPhonebook").Rows(0).Item("SNo")
        txtName.Text = ds.Tables("SLAPhonebook").Rows(0).Item("Name")
        txtLastName.Text = ds.Tables("SLAPhonebook").Rows(0).Item("LastName")


'here in formload event i also binded data grid with dataset
DataGrid1.SetDataBinding(ds, "sla")
DataGrid1.DataSource = ds.Tables(0)



'friends every thing is working fine, but when i click to move next record in table, it moves but only in text boxes which i connected with dataset.tables(rows), i want to datagrid to also move to next record as soon as i press next record button

' I used following code for "next Record Button", to move on next record

if inc <> MaxRows - 1 Then
            inc = inc + 1
            NavigateRecords()
        Else
            MsgBox("No More Rows")

        End If

DataGrid1.DataSource = ds.Tables(inc)
DataGrid1.SetDataBinding(ds, "sla")

Please Help My with My Question how to move current record in datagrid, i mean when i press Next record button then datagrid's data (table) also should move to next record

or when i click any record in datagrid, then the current record of dataset also should move to clicked record of datagrid, so that i also may see datagrid's clicked record in textboxes

in short i want to use default feature of vb6's ado control, when we bind datagrid with ado control, it worked autometically, both data grid and adodc wer connected each other at a time, so that moving next record also apears in datagrid. please help me in my question, i m new to .net i need ur help

Have a look,

Public Class Form1
    Dim dt As DataTable
    Dim da As OleDb.OleDbDataAdapter

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        dt=new DataTable()
        da = New OleDbDataAdapter("Select * From sla", "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=D:\SLAPhonebook.mdb")
        da.Fill(dt)

        DataGridView1.DataSource = dt
        TextBox1.DataBindings.Add("Text", dt, "SNo")
        TextBox2.DataBindings.Add("Text", dt, "Name")
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.BindingContext(dt).Position += 1
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Me.BindingContext(dt).Position -= 1
    End Sub
End Class
