Thread Memory (runtime) dataset update from another form

Hi All,

I have a running memory (runtime) dataset on form1 attached to a grid,
working fine on form1. I now need to update some values for dataset from
form2.

When i try this, something like "dataset needs to be in editable mode"
shows up.

Sample code i use (on form2):

form1.dataset.update;
form1.dataset.columns['field'].asFloat:= 1;
form1.dataset.save;

I've tried several things - cannot get it working. I have only 1 event
defined for the runtime dataset (onrowchanged). Maybe other events are
needed?

Thanks in advance,

Hüseyin

1. I'd recommend creating a member function on Form1 to update things within the form unit rather than manipulating data willy-nilly from other forms/units.

2. Have you accidentally named both forms Form1, that's a common mistake, at least one i've made before.

It's always helpful for other users having the same problem to post what
the error was und how you fixed it.
