C# 设置DataGridViewComboxCell的颜色？

我使用了这个代码片段

// Second Column: Hand to use
DataGridViewComboBoxCell handToUseCell = (DataGridViewComboBoxCell)this._robotSelectionDataGridView[Common.SECOND_COLUMN, currentRow];
handToUseCell.Items.Clear();
foreach (Hand hand in robotInfo.Hands)
{
  handToUseCell.Items.Add(hand.Name.ToString());
}
handToUseCell.DisplayStyle = (handToUseCell.Items.Count > 1) ? DataGridViewComboBoxDisplayStyle.ComboBox :
                                                    DataGridViewComboBoxDisplayStyle.Nothing;
handToUseCell.Value = handToUseCell.Items[0];
handToUseCell.Style.BackColor = Color.DimGray;

但背面颜色没有改变。设置cell.style.backcolor时会发生什么情况？

尝试以下内容

// Second Column: Hand to use
DataGridViewComboBoxCell handToUseCell = (DataGridViewComboBoxCell)this._robotSelectionDataGridView[Common.SECOND_COLUMN, currentRow];
handToUseCell.Items.Clear();
foreach (Hand hand in robotInfo.Hands)
{
  handToUseCell.Items.Add(hand.Name.ToString());
}
handToUseCell.DisplayStyle = (handToUseCell.Items.Count > 1) ? DataGridViewComboBoxDisplayStyle.ComboBox :
                                                    DataGridViewComboBoxDisplayStyle.Nothing;
handToUseCell.Value = handToUseCell.Items[0];
handToUseCell.Style.BackColor = Color.DimGray;

handToUseCell.DefaultCellStyle.BackColor=Color.Red

// Second Column: Hand to use
DataGridViewComboBoxCell handToUseCell = (DataGridViewComboBoxCell)this._robotSelectionDataGridView[Common.SECOND_COLUMN, currentRow];
handToUseCell.Items.Clear();
foreach (Hand hand in robotInfo.Hands)
{
  handToUseCell.Items.Add(hand.Name.ToString());
}
handToUseCell.DisplayStyle = (handToUseCell.Items.Count > 1) ? DataGridViewComboBoxDisplayStyle.ComboBox :
                                                    DataGridViewComboBoxDisplayStyle.Nothing;
handToUseCell.Value = handToUseCell.Items[0];
handToUseCell.Style.BackColor = Color.DimGray;

或

// Second Column: Hand to use
DataGridViewComboBoxCell handToUseCell = (DataGridViewComboBoxCell)this._robotSelectionDataGridView[Common.SECOND_COLUMN, currentRow];
handToUseCell.Items.Clear();
foreach (Hand hand in robotInfo.Hands)
{
  handToUseCell.Items.Add(hand.Name.ToString());
}
handToUseCell.DisplayStyle = (handToUseCell.Items.Count > 1) ? DataGridViewComboBoxDisplayStyle.ComboBox :
                                                    DataGridViewComboBoxDisplayStyle.Nothing;
handToUseCell.Value = handToUseCell.Items[0];
handToUseCell.Style.BackColor = Color.DimGray;

handToUseCell.CellStyle.BackColor=Color.Red

// Second Column: Hand to use
DataGridViewComboBoxCell handToUseCell = (DataGridViewComboBoxCell)this._robotSelectionDataGridView[Common.SECOND_COLUMN, currentRow];
handToUseCell.Items.Clear();
foreach (Hand hand in robotInfo.Hands)
{
  handToUseCell.Items.Add(hand.Name.ToString());
}
handToUseCell.DisplayStyle = (handToUseCell.Items.Count > 1) ? DataGridViewComboBoxDisplayStyle.ComboBox :
                                                    DataGridViewComboBoxDisplayStyle.Nothing;
handToUseCell.Value = handToUseCell.Items[0];
handToUseCell.Style.BackColor = Color.DimGray;

让我知道结果。。
希望有帮助。
您是要为下拉列表设置背景色还是元素（如图所示）本身设置背景色？我试图为下拉列表添加背景色。@Vidhya您是在windows应用程序DataGridViewComboxCell中尝试的吗？没有“DefaultCellStyle”和“CellStyle”属性。请尝试参考此文档。。。让我知道它是否有用。。

handToUseCell.Items.Clear();
foreach (Hand hand in robotInfo.Hands)

}
handToUseCell.DisplayStyle = (handToUseCell.Items.Count > 1) ? DataGridViewComboBoxDisplayStyle.ComboBox :
                                                    DataGridViewComboBoxDisplayStyle.Nothing;
handToUseCell.Value = handToUseCell.Items[0];
handToUseCell.Style.BackColor = Color.DimGray;
