Hello Support,

“this.entBox.clientWidth” in IE return 0.

and In FF returns some value say 672px for 4 columns.

I got js error as invalid argument at this line in dhtmlxgrid_splt.js = this.entBox.offsetHeight-wcor+(this._sizeFix||0)+“px”;

I just debug and found that " " gets negative value.

This happens because “this.entBox.clientWidth” retuns 0.

How to resolve?

This happens because “this.entBox.clientWidth” retuns 0.
Such situation can occur only if you initialize the grid in split mode inside a hidden container, or grid’s container has zero size.
Just init component when grid container in visible state, or set some fixed sizes to grid container via styles to resolve issue.
