Column width

I would like to set the width of the column with javascript according to window size. I've tried the following javascript code but it does not work:
    var treegridObj = $("#treeGrid").data("ejTreeGrid");
    var numColumns = treegridObj.model.columns.length - 2;
    var swidth1 = $(window).width() - lOffset - rOffset;
    var colWidth = (swidth1 - 445) / numColumns;
    for (var i = 2; i < treegridObj.model.columns.length; i++) {
        treegridObj.model.columns[i].width = 10;
        treegridObj._columnsWidthCollection[i] = 10;
    }
    treegridObj.refreshContent();
    treegridObj.renderRecords();

Can you help me? Thanks.
Best regards.

Hi Cosimo,
Currently there is no built-in support in TreeGrid to change the width of the columns on resizing browser window, without re-rendering the TreeGrid widget . But we can provide a workaround for your requirement at present , please find the below code example to achieve your requirement,

var treegridObj = $("#Treegrid").data("ejTreeGrid");                                for (var i = 2; i < treegridObj.model.columns.length; i++) {                     treegridObj.model.columns[i].width = 10;                     treegridObj._columnsWidthCollection[i] = 10;                     }                 treegridObj.setWidthToColumns(); In addition to that set EnableResize="true" for dynamic window resize.

We have prepared a sample regarding this , please find the sample in the below location,
