EDIT: I realized a little late that it was bound to a DataTable. In that case the idea is the same, and you can cast to a DataRowView then take its Row property to get a DataRow if you want to work with that class.
foreach (var item in checkedListBox1.CheckedItems)
{
var row = (item as DataRowView).Row;
MessageBox.Show(row["ID"] + ": " + row["CompanyName"]);
}
You would need to cast or parse the items to their strongly typed equivalents, or use the System.Data.DataSetExtensions namespace to use the DataRowExtensions.Field method demonstrated below:
foreach (var item in checkedListBox1.CheckedItems)
{
var row = (item as DataRowView).Row;
int id = row.Field<int>("ID");
string name = row.Field<string>("CompanyName");
MessageBox.Show(id + ": " + name);
}
You need to cast the item to access the properties of your class.
foreach (var item in checkedListBox1.CheckedItems)
{
var company = (Company)item;
MessageBox.Show(company.Id + ": " + company.CompanyName);
}
Alternately, you could use the OfType extension method to get strongly typed results back without explicitly casting within the loop:
foreach (var item in checkedListBox1.CheckedItems.OfType<Company>())
{
MessageBox.Show(item.Id + ": " + item.CompanyName);
}
