how do i make just some items editable?

how do i make just some items editable?

for example just the ones that have the id like this id=“attrib131”, id=“attrib44” etc?

You can use onEditCell event

    if (id==“attrib131” || id==“attrib44”) return true;
    return false;

Also grid allows to lock rows ( it can be done directly from XML ) , locked rows can’t be edited

How to set LockRow in XML?  I would like the default to be that all rows are locked, and have control over what rows/cells can be locked programmatically.

You can use row@locked in XML

<row id=‘some’ locked=“true”>…

rows with such attribute will be created in locked state, which can be reset from js code by grid.lockRow(‘some’,false)
