ListViewInsertEventArgs.Values Property

Gets the values for the record to insert.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public IOrderedDictionary Values { get; }

Property Value

Type: System.Collections.Specialized.IOrderedDictionary
The values for the record to insert.

Use the Values property to access the values of the fields for the record to insert. For example, you can validate or HTML-encode the values of the record before it is inserted in the data source.

The Values property returns an OrderedDictionary object that implements the IOrderedDictionary interface. The OrderedDictionary object contains DictionaryEntry objects that represent the fields of the record. To access the field names, use the Keys property of the OrderedDictionary object. To access the field values, use the Values property.

NoteNote

As a shortcut, you can use the indexer of the OrderedDictionary object to access the field values directly. The advantage of using the indexer is that it returns field values directly. Data source controls that rely on the field order (such as AccessDataSource) can access field values only by index.

The following example shows how to iterate through the Values collection. This code example is part of a larger example provided for the ListViewInsertEventArgs class.

void ContactsListView_ItemInserting(Object sender, ListViewInsertEventArgs e)
{
  // Iterate through the values to verify if they are not empty.
  foreach (DictionaryEntry de in e.Values)
  {
    if (de.Value == null)
    {
      Message.Text = "Cannot insert an empty value.";
      e.Cancel = true;
    }
  }
}
