+	* test/1.1/webcontrols/dbpage1.aspx: do not rely on the
+	OnTextChanged to fire the Filter_Changed handler method. Doing
+	that makes the sample miss situations when the user clicks Submit
+	several times in a row without changing the filters - the result
+	of this is that no table is show in the output. Filter_Changed is
+	fired as the OnClick handler of the Submit button. Fixes bug
+	#381972.
+	Should the filter fail to return any results, an appropriate
+	information is shown.
