fixed column width ?

Users can move mouse over the vertical line between columns and drag to adjust the width of that column. I dont want users to change the dhtmlx grid column width.

how can I do that ?

try use the function below:
mygrid.enableResizing(list);
the list is your column count.
for example,
mygrid.enableResizing(“false, false, false”);

it fixed my problem. Thanks lot !!!
