关于datagridview的dataerror事件如何定位cell的问题
datagridview的dataerror事件如何定位是哪个cell出现问题
比如加载某个数据的时候,我希望能在datagridview定位到这个cell,显示红色.
我在dataerror里面用
DataGridView1.CurrentCell.Style.BackColor = Color.Red
不能实现.

谢谢各位提供建议!


以下是msdn里面的dataerror代码

VB.NET code

Visual Basic 複製程式碼 Private Sub DataGridView1_DataError(ByVal sender As Object, _ByVal e As DataGridViewDataErrorEventArgs) _Handles DataGridView1.DataError    MessageBox.Show("Error happened " _        & e.Context.ToString())    If (e.Context = DataGridViewDataErrorContexts.Commit) _        Then        MessageBox.Show("Commit error")    End If    If (e.Context = DataGridViewDataErrorContexts _        .CurrentCellChange) Then        MessageBox.Show("Cell change")    End If    If (e.Context = DataGridViewDataErrorContexts.Parsing) _        Then        MessageBox.Show("parsing error")    End If    If (e.Context = _        DataGridViewDataErrorContexts.LeaveControl) Then        MessageBox.Show("leave control error")    End If    If (TypeOf (e.Exception) Is ConstraintException) Then        Dim view As DataGridView = CType(sender, DataGridView)        view.Rows(e.RowIndex).ErrorText = "an error"        view.Rows(e.RowIndex).Cells(e.ColumnIndex) _            .ErrorText = "an error"        e.ThrowException = False    End IfEnd Sub 

[解决办法]
ByVal e As DataGridViewDataErrorEventArgs这个事件的参数e里面有两个属性：

e.ColumnIndex, e.RowIndex

估计就是列和行的Index，

dataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Style.BackColor = = Color.Red
[解决办法]

VB.NET code

    Private Sub DataGridView1_DataError(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewDataErrorEventArgs) Handles DataGridView1.DataError        DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Style.BackColor = Color.Red    End Sub
