控件，其中包含大约5000个项目。我正在使用ListView搜索BackgroundWorker控件并在其中找到项目。问题是，当我找到一个项目时，我需要更改它的ListView并滚动到我的backcolor中。
我的ListView代码：
Backgroundworker一切正常，但是每次找到匹配项时都会触发用于更新我的private void SearchTrackerList(int column,string text)
{
foreach (ListViewItem lvi in ListView_DeviceList.Items)
{
if (lvi.SubItems[column].Text.Equals(text))
{
this.Invoke(new MethodInvoker(delegate
{
ListView_DeviceList.Items[lvi.Index].EnsureVisible();
lvi.BackColor = Color.Yellow;
}
));
deviceSearchFound = true;
}
}
}
的我的调用，这会减慢整个代码的速度。找到项目后更新我的ListView控件的正确方法是什么？
