1.小窗口如图所示

![Image 1][]

相应的后台代码：

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][]

1  public  partial  class  HideColumn : Form  
  2  \{  
  3  public  DataGridView dgv \{  set ;  get ; \}  
  4   
  5  public  HideColumn()  
  6  \{  
  7  InitializeComponent();  
  8  \}  
  9   
 10  private  void  btnHideColumn\_Click( object  sender, EventArgs e)  
 11  \{  
 12  dgv.Columns\[ 3 \].Visible  =  false ;  
 13  \}  
 14  \}

2.在含有datagridview的窗口

![Image 1][]

当单击ShowHideColumn时，执行的操作代码如下：

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][]

1  private  void  showHideToolStripMenuItem\_MouseDown( object  sender, MouseEventArgs e)  
 2  \{  
 3  HideColumn hc  =  new  HideColumn();  
 4  hc.dgv  =  dataGridView1;  
 5  hc.Visible  =  true ;  
 6   
 7  \}

弹出的窗口具有模式对话框的代码如下：

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][]

1  private  void  showHideToolStripMenuItem\_MouseDown( object  sender, MouseEventArgs e)  
 2  \{  
 3  HideColumn hc  =  new  HideColumn();  
 4  hc.dgv  =  dataGridView1;  
 5  hc.ShowDialog();  
 6   
 7  \}

2.冻结窗口的代码如下。代码出现在小窗口中

代码如下：

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][]

1 private  void  btnSure\_Click( object  sender, EventArgs e)  
  2  \{  
  3  int  rowNum  =  Convert.ToInt32(tbRowNum.Text);  
  4  int  columnNum  =  Convert.ToInt32(tbColumnNum.Text);  
  5  if  (rowNum  >=  0  &&  rowNum < dgv.Rows.Count)  
  6  \{  
  7  dgv.Rows\[rowNum\].Frozen  =  true ;  
  8   
  9  \}  
 10  if  (columnNum  >=  0  &&  columnNum  <  dgv.Columns.Count)  
 11  \{  
 12  dgv.Columns\[columnNum\].Frozen  =  true ;  
 13  \}  
 14  \}

用途：可以设那一些用户可以访问哪一些权限。
