在EditingControlShowing中获取当前单元格值

Question

我要做的是，如果我键入＆＃34; red＆＃34;进入一个单元格，然后单元格的背景颜色变为红色，如果我键入＆＃34;蓝色＆＃34;进入一个细胞，然后细胞的背景颜色变为蓝色。我遇到的问题是，如果我键入＆＃34;蓝色＆＃34;，只有＆＃34; blu＆＃34;记录为mystring，因为textchanged事件记录更改前的单元格值，因此单元格的背景颜色不会因此而改变颜色。我希望有人可能知道如何在文本更改后获取当前单元格值。我目前的代码如下（这只是一个例子）。任何想法或帮助将不胜感激，谢谢。

    Private Sub DataGridView1_CurrentCellDirtyStateChanged(sender As Object, e As EventArgs) Handles DataGridView1.CurrentCellDirtyStateChanged
    Me.DataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit)
End Sub

Dim EditingControl As DataGridViewTextBoxEditingControl

Private Sub DataGridView1_EditingControlShowing(sender As Object, e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing

    EditingControl = e.Control
    AddHandler EditingControl.TextChanged, AddressOf EditingControl_TextChanged

End Sub

Private Sub EditingControl_TextChanged(sender As Object, e As EventArgs)

    mystring = Me.DataGridView1.CurrentCell.Value
    If mystring = "red" Then
        EditingControl.BackColor = Color.Red
    ElseIf mystring = "blue" Then
        EditingControl.BackColor = Color.Blue
    Else
        EditingControl.BackColor = Color.White
    End If

End Sub
