Winform dview hides columns and freeze windows in a pop-up window

1. Small Window

 

 

Corresponding backgroundCode:

View code 1   Public   Partial   Class Hidecolumn: Form
2 {
3 Public Datagridview dgv { Set ; Get ;}

11 {
12 Dgv. Columns [ 3 ]. Visible =   False ;
13 }
14 }

 

2. In the window containing the datagridview

 

 

 

When you click showhidecolumn, the operation code is as follows:

 

View code 1   Private   Void Showhid1_lstripmenuitem_mousedown ( Object Sender, mouseeventargs E)
2 {
3 Hidecolumn HC =   New Hidecolumn ();
4 HC. dgv = Datagridview1;
5 HC. Visible =   True ;

7 }

The code for the pop-up window with a mode dialog box is as follows:

View code 1 Private   Void Showhid1_lstripmenuitem_mousedown ( Object Sender, mouseeventargs E)

5 HC. showdialog ();
6
7 }

 

2. The code for freezing the window is as follows. Code appears in a small window

View code 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 {
