WebDataGrid JavaScript error when using Firefox "scrollStyleSheet is null"
posted

Dear Infragistics Support

I have a problem when using the WebDataGrid with Firefox. On a TreeView-Click, I set the WDG-Datasource and use DataBind as well as "UpdatePanel.Update" (the WDG is inside an UpdatePanel). However, while in Chrome and Internet Explorer, this works fine, in Firefox it does not. I get an error in the JavaScript Console "this._scrollStyleSheet is null" in one of your JavaScript files. The error appears in the following method:

               _onGridScrolled: function (evnt)

               {                           

                   this._grid._ignoreCScroll = true;

                              var scroll = (this._grid._hScrBar.offsetHeight > 0) ? this._grid._hScrBar.scrollLeft : this._grid.get_scrollLeft();

 

                              if ($util.IsIE || $util.IsSafari)

                              {

                                            /* Only header or only footer is visible and there are no rows, or no header and no

                                            footer and only one row */

                                            if (this._scrollDivs && !this._scrollDivs.length)

                                                           this._scrollDivs.scrollLeft = scroll;

 

                                            for (var i = 0; this._scrollDivs && i < this._scrollDivs.length; i++)

                                                           this._scrollDivs[i].scrollLeft = scroll;

                              }

                              else

                              {

                                            this._scrollStyleSheet.left = (-scroll) + "px";

                              }

                               ...

                   }

How can I fix this error? Is there any property of the WebDataGrid which I need to set, in order for it to work?

I'm using different functionalities of the WDG, I think this error appears in connection with the ColumnFixing functionality.

Thank you
