防止ListView上的ItemChecked事件干扰使用C单击的子项#

.NET专门将此功能添加到ListView。别问我为什么。

为了摆脱它,听 NM_DBLCLK 反射的通知,并在执行此操作的处理程序中:

NativeMethods.NMHDR nmhdr = (NativeMethods.NMHDR)m.GetLParam(typeof(NativeMethods.NMHDR));

switch (nmhdr.code) {
case NM_DBLCLK:
    // The default behavior of a .NET ListView with checkboxes is to toggle the checkbox on
    // double-click. That's just silly, if you ask me :)
    if (this.CheckBoxes) {
        // How do we make ListView not do that silliness? We could just ignore the message
        // but the last part of the base code sets up state information, and without that
        // state, the ListView doesn't trigger MouseDoubleClick events. So we fake a
        // right button double click event, which sets up the same state, but without
        // toggling the checkbox.
        nmhdr.code = NM_RDBLCLK;
        Marshal.StructureToPtr(nmhdr, m.LParam, false);
    }
    break;

这是许多问题之一 ObjectListView 为你解决。即使您不使用整个项目,您也可以查看源代码并自行解决问题。
