我有一个文本框,用于从我的数据库中搜索客户。
这是我的代码:
DataView dv = new DataView(tabSearchCustomer);
dv.RowFilter = string.Format("CONVERT({0},System.String) LIKE '%{1}%'", "ID", txtboxSearchCustomer.Text);
dgvCustomers.DataSource = dv;
dgvCustomers.DataSource = dv只显示新数据,它不会在dgv中替换它。
我希望我的dgv会更新我搜索到的新数据(替换dgv中的旧数据),我该怎么做?
答案 0 :(得分:0)
public static DataTable ExecuteQuery(string storedProcedure, SqlParameter[] parameters)
{
using (SqlConnection sqlConnection = new SqlConnection(DLLConfig.GetDataBaseConnection()))
{
DataTable dataTable = new DataTable();
SqlCommand sqlCommand = new SqlCommand(storedProcedure, sqlConnection);
sqlCommand.CommandTimeout = 0;
sqlCommand.CommandType = CommandType.StoredProcedure;
foreach (SqlParameter param in parameters)
{
sqlCommand.Parameters.Add(param);
}
SqlDataAdapter sqlAdapter = new SqlDataAdapter(sqlCommand);
sqlAdapter.Fill(dataTable);
SqlConnection.ClearAllPools();
return dataTable;
}
}
用法:
dataGridView1.DataSource = ExecuteQuery().DefaultView;
