does anybody here tried to put .NET SplitContainer in a rollout? did it work?
I can put the SplitContainer in a rollout, but when I try to resize the panels by dragging the dividing line in the middle I get an error:
“System.NullReferenceException: Object reference not set to an instance of an object.”

here’s my code:


rollout ro_TEST "TEST"
(
	dotNetControl conta "System.Windows.Forms.SplitContainer" height:300
	
	fn openDialog = (
		createDialog ro_TEST width:300 height:300 
		conta.Dock = (dotnetclass "System.Windows.Forms.DockStyle").Fill
		conta.Panel1.BackColor = (dotnetclass "System.Drawing.Color").Aquamarine
	 )
   
) 

ro_TEST.openDialog()

if someone here knows how to get it work please help!

SplitContainer was designed to Split .NET controls (not MAX Rollout control!)… Create any .NET control and add SplitContainer to this control (in my code I used Label)

How it has to be:


try(destroydialog ro_TEST) catch()
rollout ro_TEST "TEST"
(
dotNetControl forma "System.Windows.Forms.Label" pos:[8,8] width:180 height:180
 
fn initFormButton =
(
conta = dotNetObject "System.Windows.Forms.SplitContainer"
conta.Dock = (dotnetclass "System.Windows.Forms.DockStyle").Fill
conta.Panel1.BackColor = (dotnetclass "System.Drawing.Color").Yellow
 
forma.controls.add conta
)
 
on ro_TEST open do 
(
initFormButton()
)
 
) 
createDialog ro_TEST width:200 height:200
