How to make a grid column with checkbox read-only when adding a new record

[PaulH]

I have a maintenance grid for data where one of the columns is an "Archived?" column which should be read-only when adding a new record or editable otherwise - database/data layer will default the value to false in any case. How can I achieve that? The relevant column in my grid is defined as follows:

            columns.Bound(t => t.IsArchived).ClientTemplate("<input type='checkbox' onclick='return false;' #= IsArchived ? checked='checked' : '' # />").HtmlAttributes(new { style = "text-align: center;" }).HeaderHtmlAttributes(new { style = "text-align: center;" }).Width(140);

Hi, Paul,

If you would like to disable the editor only when a new record is added, I could recommend using the Edit event of the widget. Namely:

.Events(ev=>ev.Edit("onEdit"))
// .   .    .
function onEdit(e) {
    if (e.model.isNew()) {
      // Disable the editor
    }
  }

I hope you find this helpful.

 

Kind regards,
