如何過濾datagrid
中的數據,例如如果您在student
數字中選擇了組合框,然後在文本字段中輸入1001。 1001中的所有記錄將顯示在datagrid
中。我使用sql server
c#中使用sql server的Datagrid過濾器
private void button2_Click(object sender, EventArgs e)
{
if (cbofilter.SelectedIndex == 0)
{
string sql;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "Server= " + Environment.MachineName.ToString() + @"\; Initial Catalog=TEST;Integrated Security = true";
SqlDataAdapter da = new SqlDataAdapter();
DataSet ds1 = new DataSet();
ds1 = DBConn.getStudentDetails("sp_RetrieveSTUDNO");
sql = "Select * from Test where STUDNO like '" + txtvalue.Text + "'";
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.CommandType = CommandType.Text;
da.SelectCommand = cmd;
da.Fill(ds1);
dbgStudentDetails.DataSource = ds1;
dbgStudentDetails.DataMember = ds1.Tables[0].TableName;
dbgStudentDetails.Refresh();
}
else if (cbofilter.SelectedIndex == 1)
{
//string sql;
//SqlConnection conn = new SqlConnection();
//conn.ConnectionString = "Server= " + Environment.MachineName.ToString() + @"\; Initial Catalog=TEST;Integrated Security = true";
//SqlDataAdapter da = new SqlDataAdapter();
//DataSet ds1 = new DataSet();
//ds1 = DBConn.getStudentDetails("sp_RetrieveSTUDNO");
//sql = "Select * from Test where Name like '" + txtvalue.Text + "'";
//SqlCommand cmd = new SqlCommand(sql,conn);
//cmd.CommandType = CommandType.Text;
//da.SelectCommand = cmd;
//da.Fill(ds1);
// dbgStudentDetails.DataSource = ds1;
//dbgStudentDetails.DataMember = ds1.Tables[0].TableName;
//ds.Tables[0].DefaultView.RowFilter = "Studno = + txtvalue.text + ";
dbgStudentDetails.DataSource = ds.Tables[0];
dbgStudentDetails.Refresh();
}
}
正如我在組合框中choosestudent數量和文本框爲1001學號輸入學號......它會顯示在DataGrid,但舊的數據仍然例如1002仍然在數據網格中 繼承人代碼 – 2010-02-11 11:59:50
在調用da.Fill(ds)之前調用DataSet上的Clear()方法, – Mart 2010-02-11 21:48:40
