I have a small question. I want to always have an invisible/hidden column as hidden field in my grid in every row (for an id). The problem is if I use the column attribute "hide:true" the column is hidden but I can't get its value when using gridOptions.api.getSelectedRows(). Just values of visible columns are returned with this function. Is there a way to have an hidden/invisible column in the grid and get its value? Thanks in advance !
