我在运行时附加了新的数据源和数据集。我也在运行时设置了过滤器,但它显示错误
找不到列 [invoice_number]
我的代码:
// Create a data adapter.
OleDbDataAdapter adapter =
new OleDbDataAdapter("SELECT * FROM gridview", connection);
// Create and fill a dataset.
DataSet sourceDataSet = new DataSet();
adapter.Fill(sourceDataSet);
// Specify the data source for the grid control.
gridControl1.DataSource = sourceDataSet.Tables[0];
// error show in this line
invoiceBindingSource.Filter =
string.Format("invoice_number = '{0}'", textEdit5.Text);
但我的 OrionSystem Access 数据库在表格 gridview 中有列“invoice_number”。我的错误是什么?
