如何遍历复选框列表并查找已选中和未选中的内容？ [英] How to loop through a checkboxlist and to find what's checked and not checked?

问题描述

我试图遍历复选框列表中的项目。如果选中，我要设置一个值。如果没有，我想设置另一个值。我正在使用以下内容，但只给了我已检查的项目：

I'm trying to loop through items of a checkbox list. If it's checked, I want to set a value. If not, I want to set another value. I was using the below, but it only gives me checked items:

foreach (DataRowView myRow in clbIncludes.CheckedItems)
{
    MarkVehicle(myRow);
}

推荐答案

for (int i = 0; i < clbIncludes.Items.Count; i++)
  if (clbIncludes.GetItemChecked(i))
    // Do selected stuff
  else
    // Do unselected stuff

如果支票处于不确定状态，这仍将返回true 。您可能要替换

If the the check is in indeterminate state, this will still return true. You may want to replace

if (clbIncludes.GetItemChecked(i))

with

if (clbIncludes.GetItemCheckState(i) == CheckState.Checked)

如果您只想包含实际检查的项目。

if you want to only include actually checked items.
