Activation Property (UltraGridCell)

Returns or sets a value that determines how an object will behave when it is activated.
Syntax
'Declaration
 
Public Property Activation As Activation
public Activation Activation {get; set;}
Remarks

The Activation property of the UltraGridCell object is subordinate to the settings of the Activation properties of the UltraGridRow and UltraGridColumn objects that contain the cell. If either the cell's row or column has its Activation property set to False, the cell cannot be activated, regardless of its own setting for Activation. The setting of the other type of parent also has no effect; setting Activation to False on a cell's row makes the cell inactive regardless of the setting of its column.

Example
Following code sets various properties that control whether the user can modify data in the UltraGrid in various ways.

Imports Infragistics.Win.UltraWinGrid

  Private Sub Button31_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button31.Click

      ' There are three properties off the override that control whether modifying rows
      ' as well as adding and deleting rows are allowed. If you set these properties
      ' on the Override off the DisplayLayout, then these settings apply to the whole 
      ' UltraGrid.
      Me.ultraGrid1.DisplayLayout.Override.AllowUpdate = DefaultableBoolean.True
      Me.ultraGrid1.DisplayLayout.Override.AllowAddNew = AllowAddNew.No

      ' set on the DisplayLayout's Override object for this band.

      ' There are Activation properties on row, column and cells that dictate whether 
      ' associated cells can be modified, or can even enter in edit mode.
      Dim column As UltraGridColumn = Me.ultraGrid1.DisplayLayout.Bands(0).Columns("CustomerID")
      Dim row As UltraGridRow = Me.ultraGrid1.Rows(0)

      ' Set the CellActivation off the column something other than AllowEdit to prevent
      ' the user from modifying cells in that column. ActivateOnly allows the user to 
      ' go into edit mode so the user can select and copy text, however the cell will
      ' be read-only thus preventing any data modification.
      column.CellActivation = Activation.ActivateOnly

      ' You can override cell activation setting for a particular row. 
      row.Activation = Activation.ActivateOnly

      ' Furthermore you can override activation on a cell as well.
      row.Cells(column).Activation = Activation.AllowEdit
