EpiShape

[Chris_Conn]

You have defined an EpiShape manually in code or you are trying to reference an existing one?

If #1) You dont want to do that, just drop one on form
If #2) You need to get a reference to that shape before you try to use it. Before var chk, add sInactive = (EpiShape)csm.GetNativeControlReference(“the guid of the shape here”);

@Chris_Conn

var chk = (EpiCheckBox)csm.GetNativeControlReference("the guid to your chkbox");
chk.CheckedChanged += (o,e) =>
{
				if((o as EpiCheckBox).Checked == true)
				{
					//sInactive.Enabled = true;
					sInactive.Status = StatusTypes.Stop;
				}
				else
				{
					sInactive.Status = StatusTypes.OK;
				}
};

Thank you @Chris_Conn ,

This helped me a lot

It’s always best practice to use the data bindings when possible over the screen controls, check out @jgiese.wci 's post above:

I would use the data view notification do perform your changes vs the actual controls. Whenever possible use the underlying data view and try to interact with controls directly as little as possible. This is just an outline won’t compile but you want something like this. Use the Wizard to get the actual EpiNotification method. private void dataView_EpiNotification(object send, args) { if(dataview.Row > -1) { if((bool)dataview.dataView[dataview.Row]["my-boolean"]) { …
