Ext.Net RadioGroup CheckedItems is always null
I'm seeing strange behaviour from Ext.Net 2.0: RadioGroup.CheckedItems is always zero in my change handler callback. In my code below RadioGroup1.CheckedItems is ALWAYS zero after checking. What am I doing wrong / how can I solve this? [DirectMethod] public void TxtVisibility() { foreach (var item in RadioGroup1.CheckedItems) { if (item.ID == "rdHourly") { txtPerHour.Hidden = false; txtAtTime.Hidden = true; } else if (item.ID == "rdAtHourly") { txtPerHour.Hidden = true; txtAtTime.Hidden = false; } } } My calling code: <ext:RadioGroup ID="RadioGroup1" runat="server" FieldLabel="" ColumnsNumber=
