MaximumDragValue Property (UltraScrollBar)

Maximum value that can be reached when using the interface to change the value.
Syntax
'Declaration
 
Public ReadOnly Property MaximumDragValue As Integer
public int MaximumDragValue {get;}
Remarks

The Infragistics ScrollBar was designed to duplicate the functionality and behavior of the intrinsic ScrollBar but utilize the Presentation Layer Framework. In the intrinsic ScrollBar, the large change value is taken into consideration when determining the maximum value that you can drag the scroll thumb, use the scroll arrows or click in the scroll track. Specifically, the maximum value is a result of Maximum minus the LargeChange plus 1. The MaximumDragValue property has been exposed to make it easier to determine this value.

Example
The following sample code illustrates how to use the CurrentState property and the PerformAction method.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinScrollBar

Private Sub button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button4.Click

    Dim state As ScrollBarState

    ' Get the current state of the scrollbar
    state = Me.ultraScrollBar1.CurrentState

    ' Check the state bit flags to see if the 'ThumbDrag' 
    ' bit is set
    If (state And ScrollBarState.ThumbDrag) = 0 Then

        ' Since the user isn't dragging the thumb 
        ' call PerformAction to go to the Minimum value
        ' if it is already at the maximum value. 
        ' Otherwise go to the maximum draggable value.
        If Me.ultraScrollBar1.Value = Me.ultraScrollBar1.MaximumDragValue Then
            Me.ultraScrollBar1.PerformAction(ScrollBarAction.First)
        Else
            Me.ultraScrollBar1.PerformAction(ScrollBarAction.Last)
        End If
    End If

End Sub
using Infragistics.Win;
using Infragistics.Win.UltraWinScrollBar;

private void button4_Click(object sender, System.EventArgs e)
{

	// Get the current state of the scrollbar
	ScrollBarState state = this.ultraScrollBar1.CurrentState;

	// Check the state bit flags to see if the 'ThumbDrag' 
	// bit is set
	if ( ( state & ScrollBarState.ThumbDrag ) == 0 )
	{
		// Since the user isn't dragging the thumb 
		// call PerformAction to go to the Minimum value
		// if it is already at the maximum value. 
		// Otherwise go to the maximum draggable value.
		if (this.ultraScrollBar1.Value == this.ultraScrollBar1.MaximumDragValue )
			this.ultraScrollBar1.PerformAction( ScrollBarAction.First );
		else
			this.ultraScrollBar1.PerformAction( ScrollBarAction.Last );
	}

}
