Hi,

Try creating the controls on the client side from JavaScript. I am not sure you can instantiate windowed  controls in ASP.NET.

BindToControl works for windows of style bsWindow. I.e. don't use it with boxes of style bsAxControl.

If you need to use ActiveX controls, just assign their CLSID or PROGID to the box.AxControlId string property. That string should transfer fine to the client side and FlowChartX will create the controls there when LoadFromString is called.

Hi,

It is better to use bsAxControl boxes because they have a reference to some COM intefaces that allow hosted controls to be serialized.

The bsWindow boxes with which you can use BindtoControl know only of the window handles and cannot serialize such windows properties.

Furthermore there is a better support for printing and print preview of bsAxControl boxes than for bound windows.

Hi,

That message is displayed in a box when the control whose CLSID is assigned to AxControlId cannot be created. I guess that means this CLSID:

{0D9B96C6-2C5D-11D7-A1FB-0050BA3D8F2A}

is not registered on the client side where the browser runs.

You might have to create a CAB file containing all OCX controls to be used on the page, and use it to install them on the client.

Hi

If you assign that CLSID  {0D9B96C6-2C5D-11D7-A1FB-0050BA3D8F2A} with JavaScript on the client side - does the control appear correctly ?

Hi,

Ok I guess ActiveX controls cannot be created on the server side because they need a parent window and the flowchart doesn't have a window in ASP.

You could try a workaround like this:

- set the AxControlId property on the server side
- but do not set Style = bsAxControl
- transfer to the client with SaveToString/LoadFromString
- now after LoadFromString on the client side for each box do

if box.AxControlId != ""
{
  box.Style = bsAxControl;
}

That will create the controls as defined by the AxControlId values set on the server side. The bad thing is that you cannot set the hosted controls properties on the server when they are not created there, you might have to devise a way to transfer values of the hosted controls via Tag/UserString.
