解决方案

< blockquote>使用 CellValueChanged 和 EditingControlShowing 事件，根据您的需要自定义它。

  private   void  dataGridView1_CellValueChanged（ object  sender，DataGridViewCellEventArgs e）
 {
  var  cell = dataGridView1.Rows [e.RowIndex ] .Cells [e.ColumnIndex]; 
 cell.Style =  new  DataGridViewCellStyle（）{BackColor = Color.White}; 
  string  fontName =   Microsoft Sans Serif ; 
 cell.Style.Font =  new 字体（fontName， 8  .25f，FontStyle.Regular ，GraphicsUnit.Pixel）; 
 
} 
 
 
 
  private   void  dataGridView1_EditingControlShowing（ object  sender，DataGridViewEditingControlShowingEventArgs e）
 {
 e.CellStyle.BackColor = Color.Yellow; 
 e.CellStyle.Font =  new 字体（e.CellStyle.Font，FontStyle.Bold）; 
 
}

EditControl =（DataGridViewTextBoxEditingControl）e.Control;

use CellValueChanged and EditingControlShowing event, customize it depends on your need.

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
       {
           var cell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
           cell.Style = new DataGridViewCellStyle() { BackColor = Color.White };
           string fontName = "Microsoft Sans Serif";
           cell.Style.Font = new Font(fontName, 8.25f, FontStyle.Regular, GraphicsUnit.Pixel);

       }



       private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
       {
           e.CellStyle.BackColor = Color.Yellow;
           e.CellStyle.Font = new Font(e.CellStyle.Font, FontStyle.Bold);

       }

Hi try this

private DataGridViewTextBoxEditingControl withEventsField_EditControl;
private DataGridViewTextBoxEditingControl EditControl {
get { return withEventsField_EditControl; }
set {
if (withEventsField_EditControl != null) {
withEventsField_EditControl.KeyDown -= EditControl_KeyDown;
}
withEventsField_EditControl = value;
if (withEventsField_EditControl != null) {
withEventsField_EditControl.KeyDown += EditControl_KeyDown;
}
}
}

private void DGV_EditingControlShowing(object sender, System.Windows.Forms.DataGridViewEditingControlShowingEventArgs e)
{
if (EditControl == null) {
EditControl = (DataGridViewTextBoxEditingControl)e.Control;
}
}
private void EditControl_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
e.CellStyle.ForeColor = Color.Red;
e.CellStyle.BackColor = Color.Black;
e.CellStyle.Font = new Font(e.CellStyle.Font, FontStyle.Bold);
