[英]How to set filter for GridView in EditValue changed ? Winforms Devexpress
[英]How to set Filter in run time ? for gridview in C#, Winforms, DevExpress
我在运行时附加了新的DataSource和DataSet。 我也在运行时中设置了过滤器,但显示错误
找不到列[发票编号]
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);
但是我的OrionSystem Access数据库在表格gridview中有“ invoice_number”列。 我的错误是什么?
或者,您始终可以设置GridView.ActiveFilterString属性。
您在绑定源上设置过滤器,但直接在网格控件上设置数据源。
您必须在绑定源上设置数据源,然后将网格的数据源设置为绑定源:
// 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 bindingsource.
invoiceBindingSource.DataSource = sourceDataSet.Tables[0];
// Specify the data source for the grid control.
gridControl1.DataSource = invoiceBindingSource;
// error show in this line
invoiceBindingSource.Filter =
string.Format("invoice_number = '{0}'", textEdit5.Text);
干杯
