Gets the values for the record to insert.
public:
property System::Collections::Specialized::IOrderedDictionary ^ Values { System::Collections::Specialized::IOrderedDictionary ^ get(); };public System.Collections.Specialized.IOrderedDictionary Values { get; }member this.Values : System.Collections.Specialized.IOrderedDictionaryPublic ReadOnly Property Values As IOrderedDictionaryProperty Value
The values for the record to insert.
Examples
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;
}
}
}
Sub ContactsListView_ItemInserting(ByVal sender As Object, _
ByVal e As ListViewInsertEventArgs)
' Iterate through the values to verify if they are not empty.
For Each de As DictionaryEntry In e.Values
If de.Value Is Nothing Then
Message.Text = "Cannot insert an empty value."
e.Cancel = True
End If
Next
End Sub
Remarks
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.
Note
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.
