I want to manipulate the columns of an external list view (XsltListViewWebPart), however, as the data loads asynchronously I must wait for the data to load and the table to be generated before my code can run.
I assume I need to use a callback but can't find anything.
I ended up just polling for the existence of the table containing the data, which will have class ms-listviewtable. (I'm using jQuery here.)
$(function(){
var intervalId = setInterval(function() {
if ($('.ms-listviewtable').length > 0) {
clearInterval(intervalId);
// Code here
}
}, 100);
});
