Column that is read-only in edit mode, but can change the value programatically

[Tom]

Hi, I have a grid checkbox column that i want to stay read-only in edit mode; but i want to programatically change the value (mode.set) - and have it reflect on the grid.
How can i achieve this?

Hello Tom,


In this case the property should be set as editable in the model (which is the default configuration). Additionally you could use the edit event of the Grid, which is fired when it enters edit mode, access the editor container via the e.container parameter, retrieve the checkbox and apply the readonly attribute.

Hi Dimiter, that could be a workaround... what I'm really looking for is a way to completely prevent the column going into edit mode - because I show a 'tick' image for my boolean column and want that to remain, even after i call grid.editRow().

Hi Tom,


When InLine edit mode is used, the whole row is switched to edit mode and this behavior cannot be prevented. You could use the e.container parameter and manually append the image to the cell in the edit event handler.
