StateDisallowed Property (GridKeyActionMapping)

Gets/sets the disallowed state. These are bit flags that specify the state that the control MUST NOT be in for this mapping to be active. If the current state of the control has any of these bits turned on this mapping will be ignored.

Public Shadows Property StateDisallowed As UltraGridState

Example
The following code illustrates how to add a custom key/action mapping to the grid that will navigate to the first row in the grid when the grid has focus but is not in edit mode and the users presses the ‘H’ key (unless the ‘alt’ key is also pressed).

Imports Infragistics.Win.UltraWinGrid

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

     Dim newMapping As GridKeyActionMapping

    ' Add a custom key/action mapping to the grid that 
    ' will navigate to the first row in the grid when 
    ' the grid has focus but is not in edit mode 
    ' and the users presses the ‘H’ key (unless the
    ' 'alt’ key is also pressed). 
    newMapping = New GridKeyActionMapping(Keys.H, UltraGridAction.FirstRowInGrid, UltraGridState.InEdit, 0, Infragistics.Win.SpecialKeys.Alt, 0)

    Me.ultraGrid1.KeyActionMappings.Add(newMapping)

    ' Note: The concept applies to UltraCombo controls as
    ' well except that the combo's KeyActionMappings is
    ' a collection of a mapping class, and associated
    ' state and actiion flags, that make sense for a combo
    ' (i.e. ComboKeyActionMapping, UltraComboAction and
    ' UltraComboState.

End Sub
using Infragistics.Win.UltraWinGrid;

private void Form1_Load(object sender, System.EventArgs e)
{

	this.oleDbDataAdapter1.Fill( this.dataSet11 );

	// Add a custom key/action mapping to the grid that 
	// will navigate to the first row in the grid when 
	// the grid has focus but is not in edit mode 
	// and the users presses the ‘H’ key (unless the
	// 'alt’ key is also pressed). 
	this.ultraGrid1.KeyActionMappings.Add( 
		new GridKeyActionMapping( 
			// the key code
			Keys.H,
			// the action to take
			UltraGridAction.FirstRowInGrid,
			// disallowed state
			UltraGridState.InEdit, 
			// required state (none)
			0, 
			// disallowed special keys
			Infragistics.Win.SpecialKeys.Alt, 
			// required special keys (none)
			0 ) );

	// Note: The concept applies to UltraCombo controls as
	// well except that the combo's KeyActionMappings is
	// a collection of a mapping class, and associated
	// state and actiion flags, that make sense for a combo
	// (i.e. ComboKeyActionMapping, UltraComboAction and
	// UltraComboState.
