Moving Previous / Next set of rows

Hi,

We are facing problem in moving previous and next(e.g.list of 10 houses)data. We wrote service for incrementing next and decrementing previous page numbers. But for the last next and the first previous,after clicking twice or thrice, we are getting No data available.
We tried If block too.

Help me to fix this issue.

regards,
Priya

Dear Priya,

Strange that you can't solve this with the If block.
Why don't you give an extra paramter with your xml and check it with your If block?
If that parameter is "previous" you should hide the previous button.
If the parameter is "next" you should hide the next button.
If there is nothing in the parameter, you just show everything.

hope this helps,

Hi Erdem,

Yes, I am using extra parameters in the XML returned from the service. But using If block, only I can disable the "Previous" button in the first page. Because we can compare it with 1/0. But the "Next" value is dynamic(i.e. it varies). So I am not able to use If block for hiding "Next" button.

regards,
Priya

Dear Priya,

I suggested an Extra parameter. not an existing one. the service can check if it's the last page. and with the extra parameter you can check if you are on the last page.

hope this helps :-)

Ok Erdem. Thanks.
