RadForm subcontrols not responing after docking to RadDock

Hello support,

here is what happend:

I created a RadFrom with controlls on it.

Then i add it to my RadDock like this:

private void Add_RadForm_asDocument_ToRadDock(RadDock rd, HostWindow hw, object radform, string title)
{
    bool found = false;

    foreach (var item in radDock_main_notr.DockWindows)
    {
        if (item.GetType() == typeof(HostWindow))
        {
            if (((HostWindow)item).Name == radform.GetType().Name + "1")
            {
                found = true;
                hw = (HostWindow)item;
            }
        }
    }

    if (found == false && radform != null)
    {
        if (hw == null || hw.Text == "")
        {
            hw = rd.DockControl((System.Windows.Forms.Control)radform, DockPosition.Fill, DockType.Document);
        }
    }

    hw.Text = title;
    hw.CloseAction = DockWindowCloseAction.Close;
    hw.ToolCaptionButtons = ToolStripCaptionButtons.None;
    hw.Select();
}

The RadFrom is added to the RadDock:

Settings is the new RadFrom thats now docked.
But when i try to use the RadDropDownList then its "stucks" (also the other GUI controls):

The changed selection of the RadDropDownList will not change.
When i close the RadForm via the "x" and eropen it again it works.

Hello, Dominik,

Thank you for the provided information so far. I have reviewed the provided code snippet in the Add_RadForm_asDocument_ToRadDock method that you provided and it seems ok to me. I have also tested it in my sample project and the RadForm is correctly added to the dock. If I understand you correctly, you expect RadForm to be shown when make a selection through the RadDropDownList. However, I am not familir with the exact logic that you have behind clicking on the drop-down items.

Reading your latest post, it seems that you managed to find the solution for not showing RadFom's controls. Note, once the RadForm is added to the dock by using a HostWindow you should manage its visual appearance like showing/hiding/dock/undock, esp. especially if you want to do this on a button click or menu item click. The RadFrom should somehow be notified about the behavior that you would like to obtain. According to the provided code snippet in your last reply, it seems that you show the form upon clicking on a menu item and this is working fine.

Hence, I will change the status of this bug report to Declined since it seems there is not an issue in RadDock control itself.

I hope this information helps. If you have any other questions do not hesitate to write back.

I solved it:

private void RadMenuItem_settings_Click(object sender, EventArgs e)
{
TranslationHelperBase.TranslateFormControls(f_settings, F_Main_notr.settings.DefaultProgramLanguage);
Observers.ObserverSettings.Notify(nameof(Observers.ObserverSettings), "loadsettings");
Data.DataHandlerClass.TelerikHandler.Add_RadForm_asDocument_ToRadDock(radDock_main_notr, hw_settings, f_settings, Translation.Translation.GetTranslation(nameof(StaticMessages.ApplicationTexts.TitleSettings), F_Main_notr.settings.DefaultProgramLanguage));
f_settings.Show();
}

I needed to add ".Show()" then the behavior is fine.
