Question

下面的代码会在单击特定单元格时打开领导者的详细视图。我试图这样做，当单击一个单元格时，它会将具有所选单元格的LeaderID的任何事件的行位置添加到数组＆＃34; le＆＃34;。我知道还有其他方法可以做某些事情，但我已经这样做了，直到我编辑它并使用下面显示的if语句。

然而这行代码

If dgdEvents.Rows(n).Cells("LeaderID").Value = .Rows(i).Cells("LeaderID").Value Then

导致以下错误

未处理的类型＆＃39; System.ArgumentOutOfRangeException＆＃39;发生在mscorlib.dll

其他信息：指数超出范围。必须是非负数且小于集合的大小。

代码：

Public Sub dgdLeaders_CellClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgdLeaders.CellClick
    dbv.EditLeader()
    Dim i As Integer
    Dim n As Integer
    Dim c As Integer = 0
    With dgdLeaders
        If e.RowIndex >= 0 Then
            i = .CurrentRow.Index
            While n <> dgdEvents.Rows.Count + 1
                If dgdEvents.Rows(n).Cells("LeaderID").Value = .Rows(i).Cells("LeaderID").Value Then
                    le(c) = n
                    c = c + 1
                End If
                n = n + 1
            End While
            tbid.Text = .Rows(i).Cells("LeaderID").Value.ToString
            tbfn.Text = .Rows(i).Cells("Forename").Value.ToString
            tbsn.Text = .Rows(i).Cells("Surname").Value.ToString
            dtpdob.Value = .Rows(i).Cells("DOB").Value
            tbsr.Text = .Rows(i).Cells("Role").Value.ToString
            tbpc.Text = .Rows(i).Cells("Postcode").Value.ToString
            tbht.Text = .Rows(i).Cells("HomeTel").Value.ToString
            tbmt.Text = .Rows(i).Cells("MobileTel").Value.ToString
            tbal1.Text = .Rows(i).Cells("AddressLine1").Value.ToString
            tbal2.Text = .Rows(i).Cells("AddressLine2").Value.ToString
            tbc.Text = .Rows(i).Cells("City").Value.ToString
            tbea.Text = .Rows(i).Cells("EmailAddress").Value.ToString
            l = i
            n = 0
        End If
    End With
End Sub
