The <kbd>Shift</kbd>, <kbd>Ctrl</kbd>, and <kbd>Alt</kbd> keys do not affect this behavior.
If the <xref:System.Windows.Forms.DataGridView.SelectionMode%2A> is set to <xref:System.Windows.Forms.DataGridViewSelectionMode.RowHeaderSelect> or <xref:System.Windows.Forms.DataGridViewSelectionMode.ColumnHeaderSelect>, the same behavior occurs but with the following additions.

If <xref:System.Windows.Forms.DataGridView.MultiSelect%2A> is set to `true`, the navigation behavior does not change, but navigating with the keyboard while pressing SHIFT (including CTRL+SHIFT) will modify a multi-cell selection. Before navigation begins, the control marks the current cell as an anchor cell. When you navigate while pressing SHIFT, the selection includes all cells between the anchor cell and the current cell. Other cells in the control will remain selected if they were already selected, but they may become unselected if the keyboard navigation temporarily puts them between the anchor cell and the current cell.

# How to: Build a Table Programmatically
The following examples show how to programmatically create a <xref:System.Windows.Documents.Table> and populate it with content. The contents of the table are apportioned into five rows (represented by <xref:System.Windows.Documents.TableRow> objects contained in a <xref:System.Windows.Documents.Table.RowGroups%2A> object) and six columns (represented by <xref:System.Windows.Documents.TableColumn> objects). The rows are used for different presentation purposes, including a title row intended to title the entire table, a header row to describe the columns of data in the table, and a footer row with summary information. Note that the notion of "title", "header", and "footer" rows are not inherent to the table; these are simply rows with different characteristics. Table cells contain the actual content, which can be comprised of text, images, or nearly any other [!INCLUDE[TLA#tla_ui](../../../includes/tlasharptla-ui-md.md)] element.
## Example
## Create a table
First, a <xref:System.Windows.Documents.FlowDocument> is created to host the <xref:System.Windows.Documents.Table>, and a new <xref:System.Windows.Documents.Table> is created and added to the contents of the <xref:System.Windows.Documents.FlowDocument>.

## Create button elements
Two <xref:System.Windows.Controls.Button> elements are created, each representing one of the possible values of <xref:System.Windows.FlowDirection>. When a button is clicked, the associated property value is applied to the contents of a <xref:System.Windows.Controls.FlowDocumentReader> named `tf1`. The property value is also written to a <xref:System.Windows.Controls.TextBlock> named `txt1`.
