如何显示数据网格视图从db表记录中清空？

Question

以下是在数据网格视图中显示数据库表记录的代码

  try
            {
                Query = "Select  Code,Description,Rate,Bottles from Items ";
                dba = new SQLiteDataAdapter(Query, GlobalVars.conn);
                testDs = new DataSet();
                dba.Fill(testDs, "Items");
                dtgitems.DataSource = testDs.Tables[0];
                dtgitems.Refresh();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

Answer 2

当我希望我的gridview变空时，我使用此代码希望它有所帮助

            DataTable dtable = new DataTable();
            BindingSource bsource = new BindingSource();
            DataSet dset = new DataSet();
            dtable.Columns.Add("Delete");
            dtable.Columns.Add("FileName");
            dtable.Columns.Add("FileVersion");
            dtable.Columns.Add("FileSize");
            dtable.Columns.Add("InstallFolder");
            dtable.Columns.Add("fnameorig");
            dset.Tables.Add(dtable);
            bsource.DataSource = dset.Tables[0].DefaultView;
            Gridview1.DataSource = bsource;
