GetRowHeaderCellFromPixel(Int32,Int32,Int32) Method

Gets the row and column indexes of the row header cell at the specified pointer location.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Function GetRowHeaderCellFromPixel( _
   ByVal rowViewportIndex As Integer, _
   ByVal x As Integer, _
   ByVal y As Integer _
) As CellRange

'Usage
 
Dim instance As SpreadView
Dim rowViewportIndex As Integer
Dim x As Integer
Dim y As Integer
Dim value As CellRange
 
value = instance.GetRowHeaderCellFromPixel(rowViewportIndex, x, y)

public CellRange GetRowHeaderCellFromPixel( 
   int rowViewportIndex,
   int x,
   int y
)

Parameters

rowViewportIndex: Row index in the viewport
x: X-coordinate (in pixels) of the pointer location
y: Y-coordinate (in pixels) of the pointer location

Return Value

CellRange object containing the row and column indexes (in a ) for the cell located at the specified pointer location, or (-1, -1, 0, 0) if no cell is located at the specified location

Remarks

This method returns a CellRange object that consists of row and column coordinates and row and column counts. If a cell exists at the pixel location, then the method returns CellRange(row, column, 1, 1) where row, column are the row index and column index of the cell. If a cell does not exist at the pixel location then the method returns CellRange(-1, -1, 0, 0).

Use the x and y parameters to specify the location (pixel) on the display of the pointer (or cursor).

This method only returns cell information for pixel locations in the column headers of the sheet, and not for cells in the data area or the sheet corner or other parts of the Spread component. For cells in the data area, use GetCellFromPixel methods. For cells in the row headers, use the GetRowHeaderCellFromPixel methods.

Example

This example uses the GetRowHeaderCellFromPixel method.

private void fpSpread1MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) 
{
    FarPoint.Win.Spread.SpreadView sv = fpSpread1.GetRootWorkbook();
    sv.AddViewport(0, 1);

    FarPoint.Win.Spread.Model.CellRange cr;

    cr = sv.GetRowHeaderCellFromPixel(0, 1, e.X, e.Y);
    textBox1.Text = "You are in row header " + cr.Row.ToString();
}

Visual Basic

Private Sub FpSpread1MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles FpSpread1.MouseDown
    Dim sv As FarPoint.Win.Spread.SpreadView = FpSpread1.GetRootWorkbook()
    sv.AddViewport(0, 1)

    Dim cr As FarPoint.Win.Spread.Model.CellRange

    cr = sv.GetRowHeaderCellFromPixel(0, 1, e.X, e.Y)
    TextBox1.Text = "You are in row header " & cr.Row.ToString()
End Sub
