Hi,

I am using the latest version of RadControls for ASP.NET Ajax and get the following error (using Firefox) when returning from a Usercontrol popup window (running ASP.NET on a German Windows XP).
Any hints would be greatly appreciated.

Thanks,
Stefan

The numeric part ('161.5') of '161.5px' cannot be parsed as a numeric part of a Pixel unit.

Stack Trace:

[FormatException: The numeric part ('161.5') of '161.5px' cannot be parsed as a numeric part of a Pixel unit.]

Hi Stefan,

I think you are trying to assign a  string  value to  unit  some where in your code,

Try to convert the string value to unit as show below.

    width   = Unit.Pixel(161.5);

Hi Shinu,

I have searched all files (code, css etc) but cannot find any statement like that. However, if I set the current culture to invariant in global.asax, the error disappears (System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;)

As a consequence, all UI elements use English culture now so this is not an ideal solution.

Thanks,
Stefan

Hi,

I have the exact same problem when using Firefox 3.0.10 and the UI culture set to "fr-CA" when hitting the "X" close button. Hitting "cancel" does not cause the error. The error happens with Firefox and Safari for windows, not IE8, Opera or Chrome.

Removing the ClientEvent OnPopupShowing seems to fix the problem. Here's is the code for PopUpShowing (adapted from this thread)

function PopUpShowing(sender, eventArgs) 
    var popUp = eventArgs.get_popUp(); 
    var windowHeight = (window.innerHeight != undefined ? window.innerHeight : document.body.offsetHeight); 
    var windowWidth = document.body.offsetWidth; 
     
    var popUpWidth = popUp.style.width.substr(0,popUp.style.width.indexOf("px")); 
    var popUpHeight = popUp.style.height.substr(0,popUp.style.height.indexOf("px")); 
    popUp.style.left = ((windowWidth - popUpWidth)/2 + sender.get_element().offsetLeft).toString() + "px"
 
    var posXY = GetAbsPosXY(sender.get_element()); 
    var scrollXY = GetScrollXY(); 
    popUp.style.top = Math.max(posXY[1], scrollXY[1]).toString() + "px"
 

Here is the error I receive :

The numeric part ('573.5') of '573.5px' cannot be parsed as a numeric part of a Pixel unit.


Do you have any work around ?

Thanks

Hi dstj,

Can you please check whether appending "px" to the popup window's height/width values addresses the problem? Namely:

function PopUpShowing(sender, eventArgs)    
{    
    var popUp = eventArgs.get_popUp();    
    var windowHeight = (window.innerHeight != undefined ? window.innerHeight : document.body.offsetHeight) + "px";    
    var windowWidth = document.body.offsetWidth + "px";    
        
    var popUpWidth = popUp.style.width.substr(0,popUp.style.width.indexOf("px"));    
    var popUpHeight = popUp.style.height.substr(0,popUp.style.height.indexOf("px"));    
    popUp.style.left = ((windowWidth - popUpWidth)/2 + sender.get_element().offsetLeft).toString() + "px";    
    
    var posXY = GetAbsPosXY(sender.get_element());    
    var scrollXY = GetScrollXY();    
    popUp.style.top = Math.max(posXY[1], scrollXY[1]).toString() + "px";    
}   
 

If the problem remains, please let us know in order to research the matter further.

Kind regards,

Thanks for your help,

Appending "px" fixes the problem with Firefox, but creates a problem with IE8.

Here is the javascript error I now receive before the popup is shown:
Line: 184
Error: Invalid argument."

popUp.style.left = ((windowWidth - popUpWidth)/2 + sender.get_element().offsetLeft).toString() + "px"

Two observations/questions:

1- The Firefox problem is a server error when closing the popup, OnShowingPopup has already been called and worked. Why would modifying the javascript function do anything for the server error upon closing?

2- We're removing the "px" in this code. Why should we add it to "windowWidth" ?
var popUpWidth = popUp.style.width.substr(0,popUp.style.width.indexOf("px")); 

Thanks

Dominic.

Hi Dominic,

The observed problem is caused by the fact that Firefox 3 supports decimal (non-integer) pixel values, which the RadGrid control does not expect on the server. The issue is fixed in the last two official releases of RadControls (Q1 2009 and Q1 2009 SP1).

In your case, if you don't want to upgrade, you can round the top and left styles for the popup and make sure that they are integer values.

As far as I can see, you don't need "px" for the windowWidth variable, if you are using it to store a number (i.e. you are not using it to assign a CSS style directly).

Best wishes,
Dimo

Hi Dimo,

Rounding does fix the problem, thanks for your help! I'm using v2009.1.402.35. At the time of writing, this seems to be the latest official build.

I don't think the problem is with Firefox support for fractional pixels per say. I remind you that it works fine with an English UI culture. The problem probably is that the server-side parsing doesn't use the invariant culture to parse the fractional pixel returned by Firefox, hence it's expecting a coma (,) in French but received a period (.) from Firefox. Rounding only goes around the problem.

Thanks again,

Dominic.

Hi,

was experiencing same issue with 2011.1.413.40 and Finnish language, also solved but rounding:

var popUp;
function PopUpShowing(sender, eventArgs) {
    popUp = eventArgs.get_popUp();
    var popUpWidth = popUp.style.width.substr(0, popUp.style.width.indexOf("px"));
    popUp.style.left = (Math.round(($(window).width() - popUpWidth) / 2 + sender.get_element().offsetLeft)).toString() + "px";
    popUp.style.top = $('#' + sender.ClientID).position().top + "px";
}

maybe someone will find this usefull :)

IE 11 is throwing this same error now.

The OnPopUpShowing script is not helping because it happens on close.

Is there a way to set the on close script?

Hello Rafael,

I am afraid the issue you are facing is not replicable on our side. Could you please send a small running project that we can use to reproduce the case. Alternatively a live URL will help us as well.

Hi We have the same Issue Closing, pressing the  OK or Cancel button in a Grid Edit PopUp.
We use Dutch Language settings and it only occurs when we change the position of the dialog during edit/insert.

The application uses Telerik version v.2013.2.717.45

The Message we get is:

Unhandled exception at line 15, column 16485 in http://localhost:49573/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=4.0.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:c9cbdec3-c810-4e87-846c-fb25a7c08002:ea597d4b:b25378d2;Telerik.Web.UI:en-US:4401a8f1-5215-4b97-a426-3601ce0fa0ff:16e4e7cd:f7645509:22a6274a:ed16cbdc:24ee1bba:19620875:874f8ea2:f46195d3:92fe8ea0:fa31b949:490a9d4e:bd8f85e4:e330518b:2003d0b8:1e771326:c8618e41:aa288e2d:58366029:8674cba1:7c926187:b7778d6c:c08e9f8a:e4f8f289:a51ee93e:59462f1

0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: The numeric part ('501.85') of '501.85px' cannot be parsed as a numeric part of a Pixel unit.

We do not use any JS that does does something wirh pixels or so. This smells like a bug to us and any help on this issue is apriciated.

Thanks,
Ron

Today I also saw this error in the logs. Also Dutch language, but the browser is IE 10. Telerik version 2013.2.717.40.

Unfortunately I cannot reproduce...

Hi,

Thank you for sharing this issue to us.

I forwarded it to our developers and it will be fixed in the internal build. In the meantime could you use the following JS workaround. Place it in the end of your page.

if (Telerik.Web.UI.RadGrid)
{
    Telerik.Web.UI.RadGrid.prototype._popUpMouseUp = function (e)
    {
        if (!this.canMove)
            return;
 
        this.canMove = false;
 
        var dragHandle = this.getElementsByTagName("div")[0];
        var popUpId = dragHandle.id;
        var tableViewId = popUpId.split("__")[0];
        var tableView = $find(tableViewId);
        if (tableView)
        {
            var grid = tableView._owner;
            grid._popUpLocations[popUpId] = Math.round(parseInt(this.style.left)) + "px," + Math.round(parseInt(this.style.top)) + "px";
            grid.updateClientState();
            grid.resizeModalBackground();
        }
        Telerik.Web.UI.Grid.RestoreDocumentEvents();
    }
}

I hope this helps.

Hi, I'm just wondering if the two of you experiencing this issue are using ASP.NET StateServer instead of InProc, as I am experiencing a similar issue with Telerik Reporting.

I have been doing some testing to switch from InProc to StateServer and all of a sudden this error is occurring when I try run a Telerik Report. When I run my reports I get  "The numeric portion of 1,554px cannot be parsed as a unit of type Pixel.". This only occurs when the total width of the columns exceeds 1000px, as thats the point when the comma appears. The exception stack shows Telerik.Reporting.Drawing.Unit.Init at the top as the point where the exception is raised, clearly not something I will be able to control! 

It seems to me there is a serious issue in the underlying framework as it is not using the InvariantCulture when serialising and deserialising values. 

Telerik team - any plans to address this soon?

Hi Michael,

This is a quote from your support ticket on the same question regarding Telerik Reporting:

"The issue is not reproducible at our side whether the decimal separator is comma or dot. Please double check if you are applying through code conversion to double without applying invariant culture. You can test serializing the report instance in XML and checking how decimal values are stored in it.

If you need further help, please send us a runnable sample project illustrating the issue, and details about the result of the above suggested test.
"

If you need further help, please update your support ticket with the requested information.
