How DataGridView cells are embedded in multiple button controls

Some time ago I had a friend interview the company encountered this interview problem, he also gave me the original question to see see, and there is no special point, about this kind of problem, how to embed the cell on the grid multiple controls (such as buttons, hyperlinks, etc.), I searched the following questions on the Internet, found a lot of answers but all messy, This article helps you understand how to deal with this kind of problem.

The Datagirdview grid control provided by Microsoft can embed the required controls in cells by means of the Getcelldisplayrectangle () method, such as:

This. Load + = Form1_Load;

void Form1_Load (object sender, EventArgs e)
{
Mulautobtnedit ();
}

private void Mulautobtnedit ()
{
THIS.DATAGRIDVIEW1.COLUMNS.ADD ("Colbtnedit", "Embed Operation Button");
this.datagridview1.columns["Colbtnedit"]. Width = 150;
int index = this.datagridview1.columns["Colbtnedit"]. Index;
this.datagridview1.columns["Colbtnedit"]. resizable = Datagridviewtristate.false;
Button Btnadd = Getbtnbytype ("Btnadd", "new");
Button Btnedit = Getbtnbytype ("Btnedit", "Modify");
Button Btndel = Getbtnbytype ("Btndel", "delete");
THIS.DATAGRIDVIEW1.CONTROLS.ADD (Btnadd);
THIS.DATAGRIDVIEW1.CONTROLS.ADD (Btnedit);
THIS.DATAGRIDVIEW1.CONTROLS.ADD (Btndel);
Rectangle Rectangle = this.dataGridView1.GetCellDisplayRectangle (index, 0, true);//Gets the rectangular area of the current cell
Btnadd.size = Btnedit.size = Btndel.size = new Size (rectangle. WIDTH/3 + 1, rectangle. Height);
Btnadd.location = new Point (rectangle. Left, rectangle. TOP);
Btnedit.location = new Point (rectangle. Left + btnadd.width, rectangle. TOP);
Btndel.location = new Point (rectangle. Left + btnadd.width + btndel.width, rectangle. TOP);
}

Private Button Getbtnbytype (string strbtnname,string strbtntext)
{
Button btn = New button ();
Btn. Name = Strbtnname;
Btn. Text = Strbtntext;
Btn. Click + = Btn_click;
return BTN;
}

private void Btn_click (object sender, EventArgs e)
{
If (Sender is Button)
{
Button btn = (button) sender;
MessageBox.Show (String. Format ("click button: {0}", btn. Text));
}
}

：

Through the above operation can be a number of buttons embedded in the cell, regardless of maintainability, efficiency issues, only to give everyone the idea, for "HYPERLINK" control, etc. can be processed in a similar way, similar to the following URL:

In the online distribution of another way, the idea is similar, address I also posted out:

About the third party devexpress components on the grid, such as the GridView, I did not find a good solution to the above problems, there are shortcomings, insider things can be on the message board.
