DataGridParentRowsLabelStyle Enumeration

Specifies how the parent row labels of a DataGrid control are displayed.

[Visual Basic]
Public Enum DataGridParentRowsLabelStyle
public enum DataGridParentRowsLabelStyle
__value public enum DataGridParentRowsLabelStyle
enum DataGridParentRowsLabelStyle


Use the members of this enumeration to set the value of the ParentRowsLabelStyle property.

Parent rows can be displayed only if the DataGrid contains at least one DataRelation to a second DataTable, and if the AllowNavigation property is set to a value that allows navigation.


Member name Description
Both Displays both the parent table and column names.
ColumnName Displays the parent column name.
None Display no parent row labels.
TableName Displays the parent table name.


[Visual Basic] The following example iterates through each of the possible values for the DataGridParentRowsLabelStyle.

[Visual Basic] 
Private Sub ChangeParentRowLabels(ByVal myGrid As DataGrid)
   Static currentLabelStyle As Integer
   If currentLabelStyle = 4 Then currentLabelStyle = 0
   Select Case currentLabelStyle
   Case 0 
      myGrid.ParentRowsLabelStyle = DataGridParentRowsLabelStyle.None
   Case 1
      myGrid.ParentRowsLabelStyle = DataGridParentRowsLabelStyle.TableName
   Case 2
      myGrid.ParentRowsLabelStyle = DataGridParentRowsLabelStyle.ColumnName
   Case 3
      myGrid.ParentRowsLabelStyle = DataGridParentRowsLabelStyle.Both
   Case Else
      myGrid.ParentRowsLabelStyle = DataGridParentRowsLabelStyle.Both
   End Select

   ' Increment the variable.
End Sub
