Hello,

I have some command buttons in the footer area of a grid view, that when pressed perform functions for records displayed in the view. The view is set to hide records on no filter, but my command buttons always display. Is there a way to hide the footer area on no filters, and also on no records found, so I can hide the buttons when there are no records displayed?

Thank you,
Terence

Hi,

You can use javascript like this in the begining in the module header:

<script>if('0'=='»getObject:viewPage.gridView.VirtualItemCount«'){document.write('<'+'!-- ')}</script>

and in the end of the module header:

<script>if('0'=='»getObject:viewPage.gridView.VirtualItemCount«'){document.write(' --'+'>')}</script>

Code writes html comment block when there is no records.

Kind regards,

Primoz

Pril,

Thank you for the response, this worked great for when there are no records found. The buttons still display when you come to the page since no selection was made yet. I have the grid set to hide records with no filters.

Is there also a way to do this for no filters, so I can hide when no filters since records are hidden too. (I am wondering if there is an object for this so it can be handled also with the javascript)

Thanks again,
Terence

Hi,

I use this:

[compute:iif([numericQueryString:GRIDVIEWID__gvff0]>0,'BUTTON HTML STRINGS','NO FILTER CHOSEN MESSAGE')]

to compute if a filter is chosen. Replace GRIDVIEWID with the id of your gridview and gvff1 with the parameter in the url string you want to check on for filters...the gvffl0 is the first filter parameter (just look in the querystring/url if you have selected your filter to see what value and what name you need to check on.... I check if it is greater than 0 because it is a numeric filter here.....)
