如何从检查的CheckedListBox项的值

问题描述

我使用了一个以上的CheckedListBox我在C＃WinForm的。我已经有界的这种控制如下 -

I have used a CheckedListBox over my WinForm in C#. I have bounded this control as shown below -

chlCompanies.DataSource = dsCompanies.Tables[0];
chlCompanies.DisplayMember = "CompanyName";
chlCompanies.ValueMember = "ID";

我可以检查的项目的索引，但我怎样才能得到检查项目的文本和值。而如何我可以通过CheckedItems访问Text和Value枚举？

I can get the indices of checked items, but how can i get checked item text and value. Rather how can i enumerate through CheckedItems accessing Text and Value?

推荐答案

在相应的栏目将它转换回原来的类型，这将是一个DataRowView的，如果你绑定一个表，然后就可以得到Id和文字：

Cast it back to its original type, which will be a DataRowView if you're binding a table, and you can then get the Id and Text from the appropriate columns:

foreach(object itemChecked in checkedListBox1.CheckedItems)
{
     DataRowView castedItem = itemChecked as DataRowView;
     string comapnyName = castedItem["CompanyName"];
     int? id = castedItem["ID"];
}
