DhtmlxGrid filter validation

Hello, i am using dhtmlx with version 2.5

Need to validate the DhtmlxGrid filters and show a error message, is there any way to do this?

Thanks in advance

grid.getFilterElement API was added in latest builds of grid 2.5, so based on version of your build, your version may have such ability

grid.getFilterElement(index).value can be used to get value from some filter box.

For older versions , direct DOM operations can be used
