从另一个表单对数据库进行更改后如何刷新datagridview,在关闭子表单后我尝试使用click事件刷新datagridview但它不起作用,我必须使用数据集吗?
//create an OleDbDataAdapter to execute the query
dAdapter = new OleDbDataAdapter(gQuery, connString);
//create a command builder
cBuilder = new OleDbCommandBuilder(dAdapter);
//create a DataTable to hold the query results
dTable = new DataTable();
//fill the DataTable
dAdapter.Fill(dTable);
//BindingSource to sync DataTable and DataGridView
bSource = new BindingSource();
//set the BindingSource DataSource
bSource.DataSource = dTable;
//set the DataGridView DataSource
dataGridView1.DataSource = bSource;
private void button_Refresh_Click(object sender, EventArgs e)
{
dataGridView1.DataSource = bSource;
dataGridView1.Refresh();
}
帮助我,请提前谢谢
