Vb.net 以新形式编辑DataGridView中的选定行

我有一个管理系统，它有一个带有

DataGridView

显示记录的表单。 我想能够点击一行并点击“编辑”按钮，新的“编辑表单”应该会显示所有记录的详细信息

datagrid网格仅显示MSAccess中的几个字段，这些字段大约是7/21字段，当然使用select语句

单击“编辑”时，如何在新表单中显示所有字段及其详细信息

这是我的DBControl类：

Imports System.Data.OleDb

Public Class DBControl
'create db connection
Private DBCon As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;" & _
                                     "Data Source=IPM_DB.accdb;")

'prepare db command
'variable for database commands
Private DBcmd As OleDbCommand

'db data
'a place to store our data
'storing and handling
'public because will be accessed from main form

'data adapter can perform select, insert, update and elete SQL operations in data source
'executing commands against database, perform actions ie filling data table
Public DBDA As OleDbDataAdapter
'data table
Public DBDT As DataTable

'query parameters
Public Params As New List(Of OleDbParameter)

'query statistics
Public RecordCount As Integer
Public Exception As String

Public Sub ExecQuery(Query As String)
    'reset query statistics
    RecordCount = 0
    Exception = ""

    Try
        'open a connection
        DBCon.Open()

        'create db command
        DBcmd = New OleDbCommand(Query, DBCon)

        'load paramsinto db command
        Params.ForEach(Sub(p) DBcmd.Parameters.Add(p))

        'clear params list
        Params.Clear()

        'execute command and fill datatable
        DBDT = New DataTable
        DBDA = New OleDbDataAdapter(DBcmd)
        RecordCount = DBDA.Fill(DBDT)

    Catch ex As Exception
        Exception = ex.Message
    End Try

    'close connection
    If DBCon.State = ConnectionState.Open Then DBCon.Close()

End Sub

'include query & command parameters
Public Sub AddParam(Name As String, Value As Object)
    Dim NewParam As New OleDbParameter(Name, Value)
    Params.Add(NewParam)
End Sub
End Class

Public Class Edit_Incident_Record

Privte Access As New DBControl

Private CurrentRecord As Integer = 0 'Incident.dgvData.SelectedRows(0).Index


Private Sub Edit_Incident_Record_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    Dim currID As Integer = Incident.dgvData.SelectedRows(0).Cells("IncidentID").Value.ToString()
    Access.ExecQuery("SELECT * from Incidents where IncidentID = '" & currID & "'")
    Dim r As DataRow = Access.DBDT.Rows(currID)

    'Access.ExecQuery("SELECT * from Incidents where IncidentID = '" & currID & "'")

    txtIncidentID.Text = currID
    'txtSummary.Text = r("Summary").ToString
End Sub


End Class

我当前的编辑表单：

Imports System.Data.OleDb

Public Class DBControl
'create db connection
Private DBCon As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;" & _
                                     "Data Source=IPM_DB.accdb;")

'prepare db command
'variable for database commands
Private DBcmd As OleDbCommand

'db data
'a place to store our data
'storing and handling
'public because will be accessed from main form

'data adapter can perform select, insert, update and elete SQL operations in data source
'executing commands against database, perform actions ie filling data table
Public DBDA As OleDbDataAdapter
'data table
Public DBDT As DataTable

'query parameters
Public Params As New List(Of OleDbParameter)

'query statistics
Public RecordCount As Integer
Public Exception As String

Public Sub ExecQuery(Query As String)
    'reset query statistics
    RecordCount = 0
    Exception = ""

    Try
        'open a connection
        DBCon.Open()

        'create db command
        DBcmd = New OleDbCommand(Query, DBCon)

        'load paramsinto db command
        Params.ForEach(Sub(p) DBcmd.Parameters.Add(p))

        'clear params list
        Params.Clear()

        'execute command and fill datatable
        DBDT = New DataTable
        DBDA = New OleDbDataAdapter(DBcmd)
        RecordCount = DBDA.Fill(DBDT)

    Catch ex As Exception
        Exception = ex.Message
    End Try

    'close connection
    If DBCon.State = ConnectionState.Open Then DBCon.Close()

End Sub

'include query & command parameters
Public Sub AddParam(Name As String, Value As Object)
    Dim NewParam As New OleDbParameter(Name, Value)
    Params.Add(NewParam)
End Sub
End Class

Public Class Edit_Incident_Record

Privte Access As New DBControl

Private CurrentRecord As Integer = 0 'Incident.dgvData.SelectedRows(0).Index


Private Sub Edit_Incident_Record_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    Dim currID As Integer = Incident.dgvData.SelectedRows(0).Cells("IncidentID").Value.ToString()
    Access.ExecQuery("SELECT * from Incidents where IncidentID = '" & currID & "'")
    Dim r As DataRow = Access.DBDT.Rows(currID)

    'Access.ExecQuery("SELECT * from Incidents where IncidentID = '" & currID & "'")

    txtIncidentID.Text = currID
    'txtSummary.Text = r("Summary").ToString
End Sub


End Class

最后是我的编辑按钮

Private Sub btnEdit_Click(sender As Object, e As EventArgs) Handles btnEdit.Click

    If Me.dgvData.SelectedRows.Count = 0 Or Me.dgvData.SelectedRows.Count > 1 Then
        MessageBox.Show("Select just one row")
        Return
    End If

    Edit_Incident_Record.Show()

End Sub

谢谢大家!

因为它是绑定的，所以您应该能够将整个相关数据行传递给另一个表单。刚刚创建了一个方法来接收它。每次都应该使用和处理一些DB提供程序对象。您应该将

DataTable

绑定到

BindingSource

并将其绑定到网格。然后，您可以通过

current

属性从

BindingSource

获取当前记录。您获得的对象将是一个

数据行视图

，然后您可以将其传递到编辑对话框。您所要做的就是在编辑对话框中编辑

DataRowView

，网格将自动更新。@jmcilhinney:您有关于如何实际执行此操作的资源吗？非常感谢。当您自己查找时，您对找到的资源有什么不了解的？因为它是绑定的，所以您应该能够将整个相关数据行传递给另一个表单。刚刚创建了一个方法来接收它。每次都应该使用和处理一些DB提供程序对象。您应该将
