c＃事件不正确地触发窗体
我想知道这里发生了什么。我有一个CheckedListBox，其中包含一些已勾选和一些未勾选的项目。我试图找到一种方法来确定控件选择中的增量。我尝试过这样的繁琐 - 但只是部分时间有效，我相信这是一个更优雅的解决方案。一个可能相关的问题是myCheckBox_ItemCheck事件在表单加载时触发 - 在我有机会执行ItemCheck之前。这是我到目前为止所拥有的：
void clbProgs_ItemCheck(object sender, ItemCheckEventArgs e)
{
// i know its awful
System.Windows.Forms.CheckedListBox cb = (System.Windows.Forms.CheckedListBox)sender;
string sCurrent = e.CurrentValue.ToString();
int sIndex = e.Index;
AbstractLink lk = (AbstractLink)cb.Items[sIndex];
List<ILink> _links = clbProgs.DataSource as List<ILink>;
foreach (AbstractLink lkCurrent in _links)
{
if (!lkCurrent.IsActive)
{
if (!_groupValues.ContainsKey(lkCurrent.Linkid))
{
_groupValues.Add(lkCurrent.Linkid, lkCurrent);
}
}
}
if (_groupValues.ContainsKey(lk.Linkid))
{
AbstractLink lkDirty = (AbstractLink)lk.Clone();
CheckState newValue = (CheckState)e.NewValue;
if (newValue == CheckState.Checked)
{
lkDirty.IsActive = true;
}
else if (newValue == CheckState.Unchecked)
{
lkDirty.IsActive = false;
}
if (_dirtyGroups.ContainsKey(lk.Linkid))
{
_dirtyGroups[lk.Linkid] = lkDirty;
}
else
{
CheckState oldValue = (CheckState)e.NewValue;
if (oldValue == CheckState.Checked)
{
lkDirty.IsActive = true;
}
else if (oldValue == CheckState.Unchecked)
{
lkDirty.IsActive = false;
}
_dirtyGroups.Add(lk.Linkid, lk);
}
}
else
{
if (!lk.IsActive)
{
_dirtyGroups.Add(lk.Linkid, lk);
}
else
{
_groupValues.Add(lk.Linkid, lk);
}
}
}
private void btSave_Click(object sender, EventArgs e)
{
List<AbstractLink> originalList = new List<AbstractLink>(_groupValues.Values);
List<AbstractLink> changedList = new List<AbstractLink>(_dirtyGroups.Values);
IEnumerable<AbstractLink> dupes = originalList.ToArray<AbstractLink>().Intersect(changedList.ToArray<AbstractLink>());
foreach (ILink t in dupes)
{
MessageBox.Show("Changed");
}
if (dupes.Count() == 0)
{
MessageBox.Show("No Change");
}
}
public bool Equals(ILink other)
{
if (Object.ReferenceEquals(other, null)) return false;
if (Object.ReferenceEquals(this, other)) return true;
return IsActive.Equals(other.IsActive) && Linkid.Equals(other.Linkid);
}
