hi,
I'm using a radlistview with raddatapager to view the selected records in a database after a search. Now so that when you click on raddatapager to see the records in the listview, it should retry the connection to the database and re-run the query select sql, I thought of using the data caching using the method OutputCache. Obviously use the OutputCache only if they do not change the search parameters. But now I have a problem that I set the radlistview to 10 records per page, load 25 records, I have 3 pages to be displayed, using the OutputCache when licco DataPager on arrival to the second page and then stops do not go forward. I thought of setting the html code on the page this parameter: <% @ OutputCache duration = "300" VaryByParam = "_str1, _str2, RadDataPager1"%>, but nothing does not work. send time is the html code of the page, and the code vb net.
html code:
vbnet code:
help me
bye
