怎样判断一个DataGrid多行被选中?并且删除这多行?

[jackjack]

在一个button里实现该功能?

[mynewpc]

SendKeys.Send("{DELETE}")

楼上的兄弟:
用这说的个有问题,
有时会报一些莫名其妙的错误!!!

[mynewpc]

不会吧,你把错误信息贴出来看看

[jackjack]

还要加DataGrid1.focus才能用
严重错误:未将对象引用设置到对象的实例

[mynewpc]

这也简单,不会再有别的问题吧?

[jackjack]

有其他的问题
不过不在这个问题范围内
新增一条记录也会报这个错
刚发现,新增好几条记录不定
奇怪

Public Function GetSelectedRows(ByVal datagrid1 As DataGrid) As System.Collections.ArrayList
Dim al As New System.Collections.ArrayList()
Dim i As Integer
' line assume's datasource is dataset - if datasource is datatable 2nd option
' While i < CType(dataGrid1.DataSource, DataSet).Tables(0).Rows.Count 'option 1
While i < CType(datagrid1.DataSource, DataTable).Rows.Count 'option 2
If datagrid1.IsSelected(i) Then
al.Add(i)
End If
i = i + 1
End While
Return al
End Function 'GetSelectedRows
Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim s As String = "Selected rows:"
Dim o As Object
For Each o In GetSelectedRows(dataGrid1)
s += " " + o.ToString()
Next o
MessageBox.Show(s)
End Sub 'button1_Click
