SetEditorValue Method (ImageCellType)

Sets the value of the editor control (does nothing since this cell type does not support editing).

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Sub SetEditorValue( _
   ByVal value As Object _
)

'Usage
 
Dim instance As ImageCellType
Dim value As Object
 
instance.SetEditorValue(value)

public override void SetEditorValue( 
   object value
)

Parameters

value: Value of editor control (as object)

Example

This example subclasses the check box cell type to illustrate the use of the methods, but would be the same for any of several cell types.

class myCkBox  : FarPoint.Win.Spread.CellType.CheckBoxCellType
{
CheckBox ckbx = new CheckBox();

public myCkBox()
{
}
new event EventHandler EditingCanceled;
new event EventHandler EditingStopped;

public override void StartEditing(EventArgs e, bool selectAll, bool autoClipboard)
{
   return;
}
public override void CancelEditing()
{
   EditingCanceled(ckbx, EventArgs.Empty);
   base.FireEditingCanceled();
}
public override bool StopEditing()
{
   if (EditingStopped != null)
   {
      EditingStopped(ckbx, EventArgs.Empty);
      base.FireEditingStopped();
      return true;
   }
   else
   {
      return false;
   }
}

public override bool IsReservedKey(KeyEventArgs e)
{
   return base.IsReservedKey(e);
}
public override object IsReservedLocation(Graphics g, int x, int y, Rectangle r, FarPoint.Win.Spread.Appearance appr, object

}
public override Size GetPreferredSize(Graphics g, Size size, FarPoint.Win.Spread.Appearance appr, object value, float zoom)
{
   return base.GetPreferredSize(g, size, appr, value, zoom);
}
public override object Parse(string s)
{
   return base.Parse(s);
}
public override string Format(object o)
{
   return base.Format(o.ToString());
}
public override Control GetEditorControl(FarPoint.Win.Spread.Appearance appearance, float zoomFactor)
{

{

   if (ckbx.CheckState == CheckState.Checked)
   {
      ControlPaint.DrawCheckBox(g, r.X, r.Y, r.Width - 40, r.Height - 6, ButtonState.Checked);
   }
   else if (ckbx.CheckState == CheckState.Unchecked)
   {
     ControlPaint.DrawCheckBox(g, r.X, r.Y, r.Width - 40, r.Height - 6, ButtonState.Normal);
   }
}
public override void SetEditorValue(object value)
{
   ckbx.CheckState = CheckState.Checked;
}
public override Cursor GetReservedCursor(object o)
{
   return base.GetReservedCursor(o);
}
}

private void menuItem4_Click(object sender, System.EventArgs e)
{
   myCkBox ckbx = new myCkBox();
   fpSpread1.ActiveSheet.Cells[0, 0].CellType = ckbx;
}
