Datagridview. After selecting a cell, a dotted line will appear around the cell. How can I clear it ??

The grid control is set to read-only, and the mode is set to cell.
After a cell is selected, a dotted line will appear around the cell. I want to remove the dotted line and the background color of the cell remains unchanged.
How can this problem be achieved ???

The default datagridview does not have this option, but you can achieve this through the following methods:

First, add the cellpaint event of the datagridview,CodeAs follows:
Private void maid (Object sender, maid E)
{
E. Handled = true;
E. paintbackground (E. cellbounds, true );
E. paintcontent (E. cellbounds );
}

//************************************** ****

Datagridview1.clearselection ();
Datagridview1.columnheadersdefaultcellstyle. Alignment = maid. middlecenter;

Datagridview1.defaultcellstyle. selectionbackcolor = color. greenyellow;
Datagridview1.defaultcellstyle. selectionforecolor = color. Black;

This. datagridview1.borderstyle = borderstyle. None;
This. Maid. singlehorizontal;
This. Maid. None;
This. Maid = maid. None;

// This. Maid =
// This. Maid
This. Fig = color. Red;
