推荐答案

试试这个

将自动回发设为第一个复选框为true.然后将这段代码写成选中的indexchenged事件

Hi ,

Try with this

make Auto postback true to first checklistbox. then write this code selected indexchenged event

Protected Sub CheckBoxList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBoxList1.SelectedIndexChanged
      For i As Integer = 0 To CheckBoxList1.Items.Count - 1
          If CheckBoxList1.Items(i).Selected = True Then
              CheckBoxList2.Items(i).Selected = True
          Else
              CheckBoxList2.Items(i).Selected = False
          End If
      Next


  End Sub
