Hi,
How to reset the grid
There is updateFromXML method which you can use:
grid.updateFromXML(url);
This method has more parameters (please, see the documentation dhtmlx.com/docs/products/dht … alpha.html)
Also you can call clearAll method and then load grid once again (if clearAll is called with true as a parameter, headers will be reset too):
grid.clearAll();
grid.loadXML(url);
