How to get a notification when a (floating) control is closed?

[Administrator]

I used to subscribe to dockingManager.DockVisibilityChanged event for that, but now it's also fired when the control is being docked or when the host form is minimized. Can you please suggest me how to handle it? I looked at the DockingManager's events but couldn't find an analogue of ControlClosed event.

Hi Andrew,

The dockingManager.DockVisibilityChanged is fired when the docked controls visibility state changed to either true or false. We can check the visible property of the docked control when the event gets fired. Here is the code snippet
private void dockingManager1_DockVisibilityChanged(object sender, Syncfusion.Windows.Forms.Tools.DockVisibilityChangedEventArgs arg)
{
if (!arg.Control.Visible)
{
MessageBox.Show(arg.Control.Name + " is closed" );
}
}

When docked control's visible property is false, We have initiated MessageBox to show up the notification about window closing. Herewith I have attached the sample. Please refer the sample and let me know if the problem gets resolved.

Interesting. In my case, I get the DockVisibilityChanged event (with the arg.Control.Visible == false) when I minimize the host form. I have no idea what causes it.

In my case, it's an MDI app with child forms that host dockable controls, could this be the reason?

Hi Andrew,

I am afraid that we were not able to reproduce issue . I have tried with MDI form and child windows that hosts docked controls. Herewith I have attached sample that is used here to reproduce the issue. Could you please modify the sample to reproduce the issue?. This will help us to resolve the issue soon.

In your example, there is an MDI container that simply shows SDI forms with dockable controls (new SdiForm().Show()) instead of hosting it. I'm trying to reproduce the issue, stay put...

The bug is reproduceable if you _host_ the child form instead of just showing it. Attached is an example. Run it, undock the panel in the child form to make it floating and then minimize the MdiForm. You'll get an DockVisibilityChanged event with arg.Control.Visible = false

Hi Murugan,

I've just created DT incident #31087. I'm not sure what you mean by "ES version details", though. We had 4.4.0.51 version and we recently installed another private patch 4.4.0.54

Thanks!

Hi Andrew,

We regret for the inconvenience caused.

The fix for this issue is somehow missed in the beta release. We have included the fix in our source and next release of Essential Studio v5.1 will ship with the fix in place.
