HI, I have GNU version
In the next code I define many selectboxes as the filters for a grid columns:
…
dhxGrid.makeFilter(“unidad”,0);
…

Dirección
Secretaria
…

It works.
I have a button and a function to reset the filters:
…

…
so I tried this:
…
function unsetFilterAll(){
dhxGrid.getFilterElement(0).value="";
…
}
…
And this:
function unsetFilterAll(){
document.getElementById(“unidad”).selectedIndex="-1";
…
}
both clear the selectboxes, but the grid doesn’t back to no-filtered state, I dont want to reload the dataset because it’s big.
help please.
Thanks.

With provided code you just clear selected option in select box. If you want to unfilter grid you should use following grid api:

grid.filterBy(column_index,"");
