PopupControlContainer.OnPopup

[Christian Buehlmann]

Hi syncfusion team

We have a problem with the AutoComplete control.
There is this timeout in

PopupControlContainer.OnPopup()

this.listener.ignoreDeactivateTick = Environment.TickCount + 100;

which should prevent a popup container from closing if it gains focus.

I cannot exactly resolve the problem, but this timer value seems to be exceeded in our system and therefore the dropdown is closed immediately after receiving the focus.
This occurs only when we navigate INTO the already opened auto complete drop down list by pressing (Keys.Down). Mouse selection works fine.

Could you please suggest a workaround or fix this issue?

Thank you very much
Chris

Hi Chris,
You need to derive from our PopupControlContainer, override the OnPopup method and set focus to the PopupControlContainer.See this sample attached.This works fine and the PopupControlContainer does not close. Kindly let me know if this helps you.
