Name

RowStateFilter

Synopsis

DataViewRowState state = DataView.RowStateFilter;

DataView.RowStateFilter = state;

Gets or sets a value that determines how rows are filtered based on their DataRowState. You set the RowStateFilter property using one of the values from the DataViewRowState enumeration (or a bitwise combination of values). These values are shown in Table 28-1. By default, the RowStateFilter is set to CurrentRows and shows everything except rows that are scheduled for deletion.

Table 28-1. DataViewRowState values

Value	Description
Added	A new row that is inserted into the data source when the next update is performed.
CurrentRows	Current rows, including unchanged, new, and modified rows. This is the default.
Deleted	A deleted row that is removed from the data source when the next update is performed.
ModifiedCurrent	A row that exists in the DataSet but has been modified.
ModifiedOriginal	The original version (although it has since been modified and is available as ModifiedCurrent).
None	No rows will be shown.
OriginalRows	Original rows including unchanged and deleted rows.
Unchanged	A row that exists in the DataSet and has not been modified.

Example

The following code snippet configures a view to display only deleted and added rows:

// Show deleted and added rows.

view.RowStateFilter =

    DataViewRowState.Deleted | DataViewRowState.Added;

Note

The values in the DataViewRowState enumeration don’t exactly correspond to the values in the DataRowState enumeration. This is because the DataViewRowState must take into account the state of rows (deleted, added, and so on) and indicate which version of the information should be used for display purposes (the current information or the original data queried from the data source).
