A redirect Problem

Question

By a default XXXView1_View.uix we can search for a sigle
Row with a input.But I want to let the page display the whole table rows again after a search.How should I do it?
and another problem ,can I set the Row Rangsize for the table at runtime? how should I do it?
thanks.
best regard.

Hi,hier is a example code generated by wizard. We can search a single row here through selecting e.g. "CountryName" and inputing "Germany",then we can get the single row of "Germany" in the table.And then I want to let the table "refreshed"--> shown as before searching.But I found after searching there would be
ever the selected row in the table.So I want to set a eventhandler to refresh it,but no success.
Code:
