How can you create a grid but not load any data?
If I omit the url
option then the loadError
callback is triggered.
Currently we set url:NoData.json
where NoData.json is a static file with no rows in it.
Issue is in our loadComplete
callback we'd like to dipslay a message if the grid contains no data - except we don't want to display this message on the initial load. Currently we handles this as follows:
//jqGrid load complete handler function loadComp(grid) { if (grid.getGridParam("url") != "NoData.json" && grid.getGridParam("records") == 0) { setStatus("Your search did not return any results"); } }
This just seems a little hacky.. would like to just have the grid not load any data initially.
Any ideas?
Just set opacity:0 for jqgrid element. it will work also.
jqGrid exposes a property rowNum where you can set the number of rows to display for each page.
If you use loadonce:true jqGrid change the datatype parameters to 'local' after the first load of data from the grid. All next grid reloading (sorting, paging, filtering) works local. If you want refresh the grid data from the server one more time you should set datatype to its original value ('json' or 'xml').
jqGrid('clearGridData') . jqGrid('setGridParam', {data: data, page: 1}) . trigger('reloadGrid'); } } }); )};
You should just use datatype: 'local'
initially. At the moment when you need to load the data you should change the datatype
to json
or xml
:
$("#list").jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid');
I wanted to create a grid that loads no data when the page is loaded but loads data, when the user clicks refresh or uses the search. My solution is a little bit hacky to but is very easy and works nicely.
I am using the callback event loadBeforeSend
to stop the ajax request for data when the page is loaded. My callback function removes itself so it will be executed only once.
loadBeforeSend: function (xhr, settings) { this.p.loadBeforeSend = null; //remove event handler return false; // dont send load data request }
