如何让选中的图形不能通过按“DEL”键删除？

你可以参看“Default Keyboard Navigation”章节，Delete键默认对应的是DeleteShape操作。
想修改的话，重新设置InputMap即可。
例如：

1. private void Form1_Load(object sender, System.EventArgs e)
   
2. {
   
3. 
   
4.    FarPoint.Win.Spread.InputMap im = new FarPoint.Win.Spread.InputMap();
   
5. 
   
6.    // Define the operation of pressing Enter key in cells not being edited as "Move to the next row".
   
7. 
   
8.    im = fpSpread1.GetInputMap(FarPoint.Win.Spread.InputMapMode.WhenFocused);
   
9. 
   
10.    im.Put(new FarPoint.Win.Spread.Keystroke(Keys.Enter, Keys.None), FarPoint.Win.Spread.SpreadActions.MoveToNextRow);
    
11. 
    
12.    // Define the operation of pressing Enter key in cells being edited as "Move to the next row".
    
13. 
    
14.    im = fpSpread1.GetInputMap(FarPoint.Win.Spread.InputMapMode.WhenAncestorOfFocused);
    
15.    im.Put(new FarPoint.Win.Spread.Keystroke(Keys.Enter, Keys.None), FarPoint.Win.Spread.SpreadActions.MoveToNextRow);
    
16. }
