我試圖顯示當我選擇該日期時的具體日期記錄。我已經填補了我的DataGridView這樣的：錯誤C＃datagridview過濾器特定內容
con = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=\"C:\\Users\\Fakhar Zaman\\documents\\visual studio2010\\Projects\\LabManagement\\LabManagement\\Management.mdf\";Integrated Security=True;User Instance=True");
con.Open();
SqlDataAdapter adap = new SqlDataAdapter("select id, expenseTitle, expenseAmount, date, paidBy, expenseType from Expense", con);
DataSet ds = new System.Data.DataSet();
adap.Fill(ds, "Expense");
dataGridView2.DataSource = ds.Tables[0];
adap = new SqlDataAdapter("select id, date, itemName, quantity, itemSold, priceBuy, soldPrice, totalSold, profit from ItemRecord", con);
ds = new System.Data.DataSet();
adap.Fill(ds, "ItemRecord");
dataGridView1.DataSource = ds.Tables[0];
此代碼工作正常，並顯示datagridview的值。但是，當我想過濾特定日期的內容時，它不會那樣做，而是會再次顯示完整記錄。 過濾代碼如下：
string plus = dateTimePicker1.Value.AddDays(1).ToString("yyyy-MM-dd");
string date = dateTimePicker1.Value.ToString("yyyy-MM-dd");
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = new SqlCommand("SELECT * FROM ItemRecord", con);
var dataset = new DataSet();
adapter.Fill(dataset);
//MessageBox.Show(plus +" , " + date);
this.itemRecordBindingSource.Filter = string.Format("date >= '{0:yyyy-MM-dd}' AND date < '{1:yyyy-MM-dd}'", date, plus);
//string date = dateTimePicker1.Value.ToString();
請建議我一些解決方案。
當我填表使用自動生成的代碼的數據集，它工作正常，並過濾的具體內容，但我需要上面的代碼 做工精細
this.expenseTableAdapter.Fill(this.managementDataSet21.Expense); this.itemRecordTableAdapter.Fill(this.managementDataSet21.ItemRecord);*/

在過濾代碼中加入這一行，你可以分享你如何將數據綁定到網格？ –
