Question

我想用键盘上的删除按钮删除gridview中的行。我该怎么办？

Answer 1

试试这个

在form.designer.cs文件中向您的gridView添加一个委托。找到要设置gridview属性的区域，并在该部分的底部添加此行。

this.gridview.KeyDown += new System.Windows.Forms.KeyEventHandler(gridview_KeyDown);

然后在您的事件处理程序中执行以下操作

void gridview_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
    {
        //checks to see if the delete button has been clicked and if there are selected rows
        if (ModifierKeys == Keys.Delete && gridview.SelectedRows.Count > 0)
        { 
                //perform delete
        }
    }

Answer 2

我编写此代码并删除我选择的行。

        private void GridviewName_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e)
            {
               var delete = from del in Movie_List.Requests
                            where del.Movie_Name == GridviewName.Rows[GridviewName.CurrentCell.RowIndex].Cells["ColumnName"].Value.ToString()
                             select del;
                foreach (var Item in delete)
                {
                    Movie_List.Requests.DeleteOnSubmit(Item);
                    Movie_List.SubmitChanges();
                }
            }

祝你好运
