Hi adevicq,
Advanced Filtering isn’t avaliable for the jqxGrid but for the jqxTreeGrid. Nevertheless, the way to translate those labels applies to both. In order to do it you need to set a globalization function to the localization property of the jqxGrid/jqxTreeGrid. The globalization properties that you want to change are:
...
filterApplyString: "Apply",
filterCancelString: "Cancel",
filterClearString: "Clear Filter",
filterString: "advanced",
...
Those properties are jqxTreeGrid specific. You can find all of them in the jqxTreeGrid documentation.
Here’s how apply localization:
