Dear JS-Support,

Working with ComboBox bug with TabControl I found a bug:
When you leave the the TabItem where there is a ComboBox , when you back :
the ComboBox items missing / like disappeared: but only visually.

The bug only happens when you fill combobox items manually (with .Add() ),
the NO such a bug if you fill items with ItemsSource !!!

(unfortunately not possible to use ItemsSource because of other limitation of combobox.ItemsSource : see refresh bug.)


Waiting for your urgent and kind reply,
Best Regards,
Péter

This happens with other controls on a tab too.

Try cycling the "Visibility" of the child controls on the tab when the tab becomes active. Worked for me.

Dear rkmore,

First of all thanks for your kind reply.

What you mean about 'cycling the "Visibility" ' ? -sorry, but I do not understand what you mean, what you advise

When we "click - back" to a tabItem (fill the comboboxes at certain tabitem, visit other tabitem in a tabcontrol, and go back to the first tabitem) (with two comboboxes and one listbox) I've got and Unhandled exception:
'JSIL.Bootstrap.js?20167181428:2476 Uncaught System.ArgumentException: Key already exists'


in browser debugger details (paused in debugger):

$.Method({Static:false, Public:true }, "Add",
(new JSIL.MethodSignature(null, [new JSIL.GenericParameter("TKey", "System.Collections.Generic.Dictionary`2"), new JSIL.GenericParameter("TValue", "System.Collections.Generic.Dictionary`2")], [])),
function Add (key, value) {
var bucketEntry = this.$searchBucket(key);

if (bucketEntry !== null)
throw new System.ArgumentException("Key already exists");

return this.$addToBucket(key, value);
}
);

I think it's a big bug .

Waiting for the kind reply,
