[Solved] RadDateTimePicker Error: 'get_calendar()' is null or not an object

[Martin]

I ran into problem that RadDateTimePicker client object method "hidePopup" or "hideTimePopup" threw an error message: "'get_calendar()' is null or not an object".

Here is my code piece:

function HideAllCalendars()
{
    if( typeof(jQuery) != 'undefined' )
    {
        jQuery("div.RadCalendar").each(function() {
        if (this)
        {
            // find first INPUT child node
            var obj = null;
            for( var i = 0; i < this.childNodes.length; i++ )
            {
                var node = this.childNodes[ i ];
                if( node.tagName == 'INPUT' && node.id )
                {
                    obj = node;
                    break;
                }
            }
            if( obj )
            {
                var oo = $find(obj.id)
                if(oo && oo.hidePopup && oo.hideTimePopup)
                {
                    oo.hidePopup();
                    oo.hideTimePopup();
                }
            }
        }
        });
    }
}

The oo.hidePopup or oo.hideTimePopup will throw the error message. Here is the exact error in the Telerik resource file:

for(var _32 in Telerik.Web.UI.RadDatePicker.PopupInstances){
if(Telerik.Web.UI.RadDatePicker.PopupInstances.hasOwnProperty(_32)){
var _33=Telerik.Web.UI.RadDatePicker.PopupInstances[_32].Opener;
this._hideFastNavigationPopup(_33);
Telerik.Web.UI.RadDatePicker.PopupInstances[_32].Hide();
}
}
},_hideFastNavigationPopup:function(_34){
if(_34){
var _35=_34.get_calendar()._getFastNavigation().Popup; //Error Happens here!
if(_35&&_35.IsVisible()){
_35.Hide(true);
}
}
},_setInputDate:function(_36){
this._dateInput.set_selectedDate(_36);
},_getJavaScriptDate:function(_37){
var _38=new Date();
_38.setFullYear(_37[0],_37[1]-1,_37[2]);

Why does the error happen? please help. Thanks.

Hi Martin,

Can you please provide more details how to cause the error. On my machine if( typeof(jQuery) != 'undefined' )  is always 'undefined'. Maybe you can share a runnable code snippet for me to try.

Thanks
