净：DataGridView的响应IBinding.ListChanged但不CellValueChanged事件处理程序 [英] .Net: DataGridView Responding to IBinding.ListChanged but not CellValueChanged Event Handler

问题描述

我有一个自定义IBinding一览表中引发ListChanged事件。我想ListChanged事件后重新着色DataGridView的一行。

I have a custom IBinding List which raises the ListChanged event. I would like to recolor the Datagridview row after the ListChanged event.

在DataGridView正在响应ListChanged事件并更改单元格的值，但CellValueChanged事件从来没有发射。

The Datagridview is responding to ListChanged event and changes the cell value but the CellValueChanged event is never fired.

什么datagridview的事件反映了ListChanged事件？

What Datagridview event reflects the ListChanged event?

类CustomList：IBinding

Public Sub UpdateList(Byval index as Integer)
     List(index).Active = true
     RaiseEvent ListChanged(Me, _
        New System.ComponentModel.ListChangedEventArgs _
        (System.ComponentModel.ListChangedType.ItemChanged, index))
End Sub

类CustomDataGridView：DataGridView中

Private Sub Grid_CellValueChanged(ByVal sender As Object, _
            ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
            Handles Me.CellValueChanged
     ColorRow(Rows(e.RowIndex)) ''//NeverFires
End Sub

类：表

Private Sub Form_Load(ByVal sender As Object, ByVal e As System.EventArgs) _
                Handles Me.Load

        Dim customList As New CustomList()
        customList.add(new CustomItem())
        dgv.DataSource = customList
        customList.UpdateList(0) ''//DatagridView updates but no event is raised

End Sub

更新：

CellValueChanged事件仅触发时   一个新的值被从DGV推到   在DT。不是倒过来。

CellValueChanged event only fires when a new value is pushed from the DGV to the DT. Not other way round.

推荐答案

更​​改单元格背景颜色应在行prePaint-事件来完成，如果该行被粉刷一新，这将被解雇，值更改后​​。

Changing the cells background color should be done in the RowPrePaint-Event, this will be fired if the row is repainted, after the value change.
