disable mouse over functionality in dhtmlxgrid

i want to disable mouseover functionlaity on particular column of dhtmlxgrid.

Please provide me solution for it.

You can use

if (index == INDEX) return false; //block for some column
return true;

it’s not working…i want to disable tooltip for particular column…

The code above must disable any buil-in tooltips for column in question.
Also, you may try to use

grid.enableTooltips(“true,true,false”); //parameter - list of flags for each column
