Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Sub SetSelection( _
   ByVal row As Integer, _
   ByVal column As Integer, _
   ByVal rowCount As Integer, _
   ByVal columnCount As Integer _
)

'Usage
 
Dim instance As DefaultSheetSelectionModel
Dim row As Integer
Dim column As Integer
Dim rowCount As Integer
Dim columnCount As Integer
 
instance.SetSelection(row, column, rowCount, columnCount)

public override void SetSelection( 
   int row,
   int column,
   int rowCount,
   int columnCount
)

Parameters

row: Row index of the first cell
column: Column index of the first cell
rowCount: Number of rows to add to the first cell to define the selection
columnCount: Number of columns to add to the first cell to define the selection

Remarks

Use this method to specify the anchor (first cell in a selection) and the number of rows and columns to include in the selection. Between (and including) the anchor and the extent is the selection or selected range of cells.

Example

This example assigns a DefaultSheetSelectionModel to the default SelectionModel of the spreadsheet. A selection is added to object, and then several of the methods and properties are set and the values returned to a list box. The selection can be cleared in a button click event.

private void Page_Load(object sender, System.EventArgs e)
{
   if (this.IsPostBack) return;

 FpSpread1.ActiveSheetView.ColumnCount = 8;
 FpSpread1.ActiveSheetView.RowCount = 10;
 FpSpread1.ActiveSheetView.SelectionBackColor = Color.Yellow;
 FarPoint.Web.Spread.Model.ISheetSelectionModel model = FpSpread1.ActiveSheetView.SelectionModel;
 
 bool b1, b2, b3;
 int i1;
 model.AddSelection(0, 0, 3, 3);
 b1 = model.IsAnyCellInColumnSelected(2);
 b2 = model.IsAnyCellInRowSelected(2);
 b3 = model.IsSelected(1,1);
 i1 = model.Count;
 ListBox1.Items.Add(Convert.ToString(b1));
 ListBox1.Items.Add(Convert.ToString(b2));
 ListBox1.Items.Add(Convert.ToString(b3));
 ListBox1.Items.Add(Convert.ToString(i1));
}

private void Button1_Click(object sender, System.EventArgs e)
{
 FarPoint.Web.Spread.Model.ISheetSelectionModel model = FpSpread1.Sheets[0].SelectionModel;
 model.ClearSelection();
}

Visual Basic

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   If (IsPostBack) Then Return

   Dim b1, b2, b3 As Boolean
   Dim i1 As Integer
   FpSpread1.ActiveSheetView.ColumnCount = 8
   FpSpread1.ActiveSheetView.RowCount = 10
   FpSpread1.ActiveSheetView.SelectionBackColor = Color.Yellow
   Dim model As FarPoint.Web.Spread.Model.ISheetSelectionModel = FpSpread1.Sheets(0).SelectionModel
   model.AddSelection(0, 0, 3, 3)
   b1 = model.IsAnyCellInColumnSelected(2)
   b2 = model.IsAnyCellInRowSelected(2)
   b3 = model.IsSelected(1,1)
   i1 = model.Count
   ListBox1.Items.Add(b1)
   ListBox1.Items.Add(b2)
   ListBox1.Items.Add(b3)
   ListBox1.Items.Add(i1)

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
   Dim model As FarPoint.Web.Spread.Model.ISheetSelectionModel = FpSpread1.Sheets(0).SelectionModel
   model.ClearSelection()
End Sub
