ScrollCellIntoView Method (RowScrollRegion)

Scrolls the specified cell into view for a scrolling region.
Syntax
'Declaration
 
Public Sub ScrollCellIntoView( _
   ByVal cell As UltraGridCell, _
   ByVal colScrollRegion As ColScrollRegion _
) 
public void ScrollCellIntoView( 
   UltraGridCell cell,
   ColScrollRegion colScrollRegion
)

Parameters

cell
The cell to scroll into view
colScrollRegion
The column scroll region.
Remarks

Invoke this method to ensure that a cell is viewable in a column or row scrolling region.

If this method is invoked for a colscrollregion and the column is already in the viewable area of the region, this method does not perform any scrolling.

If the colscrollregion is scrolled as a result of invoking this method, the value of the column scrolling region's Position property changes and the BeforeColRegionScroll event is generated. If the rowscrollregion is scrolled as a result of invoking this method, the BeforeRowRegionScroll event is generated.

The Scroll, ScrollColumnIntoView, ScrollGroupIntoView, and ScrollRowIntoView methods can also be invoked to scroll an object into a scrolling region's viewable area.

Example
Following code shows how to scroll a cell into view in a specific scroll region. There two ways you can scroll a cell into view: by calling ScrollCellIntoView on a RowScrollRegion or on a ColScrollRegion. Following code calls both of them but you need only one.

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid

  Private Sub Button136_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button136.Click

      Dim cell As UltraGridCell = Me.UltraGrid1.Rows(20).Cells(2)

      ' Set the back color of the cell so we can identify it on the screen.
      cell.Appearance.BackColor = Color.LightSkyBlue

      ' Get the row-scroll-region and the column-scroll-region to scroll the cell into view.
      Dim rsr As RowScrollRegion = Me.UltraGrid1.ActiveRowScrollRegion
      Dim csr As ColScrollRegion = Me.UltraGrid1.ActiveColScrollRegion

      ' Scroll the cell into view in the scroll region formed by the intersection of
      ' rsr RowScrollRegion and csr ColScrollRegion.
      rsr.ScrollCellIntoView(cell, csr)

      ' ScrollCellIntoView also does the same thing. You need to call just one of these
      ' to scroll a cell into view. Only difference is that ColScrollRegion.ScrollCellIntoView
      ' takes a leftAlign parameter that indicates whether to scroll the cell all the way to 
      ' the left.
      csr.ScrollCellIntoView(cell, rsr, False)

  End Sub
using Infragistics.Shared;
using Infragistics.Win;
using Infragistics.Win.UltraWinGrid;
using System.Diagnostics;

private void button136_Click(object sender, System.EventArgs e)
{	
		
	UltraGridCell cell = this.ultraGrid1.Rows[20].Cells[2];

	// Set the back color of the cell so we can identify it on the screen.
	cell.Appearance.BackColor = Color.LightSkyBlue;

	// Get the row-scroll-region and the column-scroll-region to scroll the cell into view.
	RowScrollRegion rsr = this.ultraGrid1.ActiveRowScrollRegion;
	ColScrollRegion csr = this.ultraGrid1.ActiveColScrollRegion;

	// Scroll the cell into view in the scroll region formed by the intersection of
	// rsr RowScrollRegion and csr ColScrollRegion.
	rsr.ScrollCellIntoView( cell, csr );

	// ScrollCellIntoView also does the same thing. You need to call just one of these
	// to scroll a cell into view. Only difference is that ColScrollRegion.ScrollCellIntoView
	// takes a leftAlign parameter that indicates whether to scroll the cell all the way to 
	// the left.
	csr.ScrollCellIntoView( cell, rsr, false );
