Question

我一直在为datagridview修复textChanged like事件，但是我无法得到我想要的结果。每当我更改其单元格上的文本时，dataGridView1必须过滤dataGridView2的内容。

这可以过滤我的dataGridView2的内容，但在此之前我必须单击dataGridView1 / press Tab外的光标。这是我的代码：

Private Sub DataGridView1_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellEndEdit


        Dim con1 As OleDbConnection = con
        con1.Open()
        Dim dt As New DataTable
        Dim _command As OleDbCommand = New OleDbCommand()
        _command.Connection = con1
        _command.CommandText = "SELECT * FROM table_name WHERE " & likeContent & ""

        dt.Load(_command.ExecuteReader)


        Me.dgv.DataSource = dt

        con1.Close()


End Sub

“likecontent”是我将文本存储在dataGridView1上的地方。

我的dataGridView2将如何通过textChanged更新，例如来自我的dataGridView1的事件？

您必须使用CellValueChangedEvent和CurrentCellDirtyStateChanged事件。

 Private Sub dgv_CellValueChanged(sender As Object, e As DataGridViewCellEventArgs) Handles dgv.CellValueChanged
   Dim con1 As OleDbConnection = con
    con1.Open()
    Dim dt As New DataTable
    Dim _command As OleDbCommand = New OleDbCommand()
    _command.Connection = con1
    _command.CommandText = "SELECT * FROM table_name WHERE " & likeContent & ""

    dt.Load(_command.ExecuteReader)


    Me.dgv.DataSource = dt

    con1.Close()
 End Sub

 Private Sub dgv_CurrentCellDirtyStateChanged(sender As Object, e As EventArgs) Handles dgv.CurrentCellDirtyStateChanged
  If dgv.IsCurrentCellDirty Then
    dgv.CommitEdit(DataGridViewDataErrorContexts.Commit)
  End If
 End Sub

如何在datagridview中执行textChanged事件？
