How to open form from datagridview

Hello,

I have a query that populates a DataGridView. I'm trying to acquire some code to get it to open a databound form when the user selects (double clicks) a row. I have a unique identifier which pulls using e.rowindex. I've completed this successfully in VB/VBA. Any ideas on this will be a huge help! The query is pretty simple. "PendingID" is the unique identifier.

This is written in VB.NET

Thanks!!!
Private Sub cmdSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSearch.Click
 

        Dim OptControlArray() As Control = {OptName, OptClaimNo, OptDate, OptCustodian}

        Dim sConnectionString, sSQL As String

        sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Documents and Settings\diw07\My Documents\Daily Backups\phone memo backend.mdb"
 

        If OptClaimNo.Checked = True Then

            sSQL = "SELECT PendingID, PendingClaimNum, Last, First, DatePending, Custodian FROM Pending WHERE PendingClaimNum Like '" & txtClaimNo.Text & "'"

        ElseIf OptName.Checked = True Then

            sSQL = "SELECT PendingID, PendingClaimNum, Last, First, DatePending, Custodian FROM Pending WHERE Last Like '" & txtLastName.Text & "'"

        ElseIf OptCustodian.Checked = True Then

            sSQL = "SELECT PendingID, PendingClaimNum, Last, First, DatePending, Custodian FROM Pending WHERE Last Like '" & cboCustodian.Text & "'"

        ElseIf OptDate.Checked = True Then

            sSQL = "SELECT PendingID, PendingClaimNum, Last, First, DatePending, Custodian FROM Pending WHERE Last Like '" & txtDateRec.Text & "'"

        End If
 

        Dim conn As New System.Data.OleDb.OleDbConnection(sConnectionString)

        Dim cmd As New System.Data.OleDb.OleDbCommand(sSQL, conn)

        conn.Open()

        Dim dat As OleDbDataAdapter = New OleDbDataAdapter(sSQL, conn)

        Dim dt As New DataTable()
 

        dat.Fill(dt)

        lstResults.DataSource = dt

        conn.Close()
 
 

    End Sub
 
 
 
 
 
 
 

********Need something here************
 

 Private Sub lstResults_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles lstResults.CellMouseDoubleClick

        Dim I As Int32

        I = e.RowIndex
 

Another query here?

        

        frm_IMT.Show()

       

    End Sub

Open in new window

Try this:
 

Private Sub dataGridView1_DoubleClick(ByVal sender As Object, ByVal e As EventArgs) 

    Dim id As String = dataGridView1.SelectedRows(0).Cells("id").ToString() 

    Dim frm As New NewForm(id) 

    'passing id into constructor of the new form 

    frm.Show() 

End Sub 

Open in new window

I've tried this but I'm getting an error "Too many arguments to Public Sub New()"


Also... won't this create a new form? I want to open an existing form and have it pull the record displayed in the DataGridView.


Thanks!

You'll need to create a constructor which accepts the id as a parameter. When you pass the id, you can retrieve the data in your form_load event

Okay I found the following example:

Module Module1
                                             
                                             Sub Main()
                                             
                                             Dim con As New Constructor(10)
                                             WriteLine(con.display())
                                             'storing a value in the constructor by passing a value(10) and calling it with the
                                             'display method
                                             Read()
                                             
                                             End Sub
                                             
                                             End Module
                                             
                                             Public Class Constructor
                                             Public x As Integer
                                             
                                             Public Sub New(ByVal value As Integer)
                                             'constructor
                                             x = value
                                             'storing the value of x in constructor
                                             End Sub
                                             
                                             Public Function display() As Integer
                                             Return x
                                             'returning the stored value
                                             End Function
                                             
         End Class                                        



Ultimately what i want to do is assign a value to "id" which would be the results of the on click event (query)? I understand (i think) what is going on in the above example, although it seems quite simple in comparison of what I'm trying to do.
