Hi all,
I am having a page contains a Form component and a DataTable component.
There is only one TextArea component and one submit button within my Form.
Below that Form, there is my DataTable. The DataTable is primarily used to
show the data from database. The TextArea, of course, is used to get the sql
query string from the user. So once the user submit his query string, the
DataTable will show the query result to him.
The problem I have is: I don't know how to update the data of my DataTable.
How can I reload the data when user submit a new query?
The following code is my rough idea (hence it's incomplete). Can any one
give me an example or a hint? Thanks in advance!
Regards,
Chih-liang Chang

public class TestPage extends WebPage {
public TestPage() {
String sql;
Model sqlQuery = new Model(sql);
super.add(new TestForm("form", sqlQuery));
IDataProvider dataProvider = new DatabaseProvider(sqlQuery);
super.add(new DataTable("table", column, dataProvider, 10));
}
private class TestForm extends Form {
public TestForm(String id, IModel sqlQuery) {
super(id, sqlQuery);
super.add(new TextArea("text", sqlQuery);
}
}
private class DatabaseProvider implements IDataProvider {
public DatabaseProvider(IModel sqlQuery) {
...
}
}
}
