JavaScript error when programatically opening panels

Hello. I have created a page with a PanelBar and three RadPanelItems. I am using the code from one of the samples where only one panel is opened and the other two disabled. You fill out text boxes and you click on the Next button and it will close the current panel, enable and open the next panel. When the next panel is opened, I am getting the following JS error:
An invalid or illegal string was specified" code: "12 Break on this error }h.insertRule(f[b]+"}",b+1);
This is only hapenning on firefox
It seems like it is injecting CSS code into the styles. Here is my code:

Wrong placement of RadContextMenu and RadTooltip in Chrome 61

*** Update from 6 June 2018 ***

The problem discussed below has been fixed in R2 2018 (2018.2.516).

*** End of update ***

Chrome 61 introduced a breaking change that breaks the positioning of the context menu and the tooltip. The issue manifests only when the page is scrolled down.

The wrong position (placement) of the context menu affects:

RadContextMenu of RadGrid
RadContextMenu and RadMenu used as a context menu
RadContextMenu in RadTreeView and other controls
RadCalendar's Popup
RadTooltip

Details and Resolution:

The positioning problem is due to the following breaking change in Chrome 61 (see full release notes):

To align with the spec and preserve browser consistency, the scrollingElement is now the documentElement in standards mode.

Chrome 61 has changed the behavior of document.scrollingElement to return document.documentElement instead of document.body to match the CSSOM View specification and this broke the positioning of the tooltip and context menu (when the EnableScreenBoundaryDetection is enabled).

The problems with the incorrect positioning of the tooltip and context menu are logged with Critical priority here and here and will be fixed in the next official release.

If you experience it, try the solutions proposed below in all browsers and share your feedback with us.

*** Update from 22 Dec 2017 ***

Since this issue can affect many controls (tooltip, window, loading panel, menu, etc.), a common solution may be to avoid the breaking change in Chrome by changing the scrolling container to a <div> of your own inside the <form and ensuring the higher-level elements do not scroll.

You can find an example at the end of the following KB article: https://www.telerik.com/support/kb/aspnet-ajax/details/incorrect-positioning-of-controls.

*** End of update ***

Solution 1 (for RadContextMenu)
Place the following override above (before) the RadTreeView or standalone RadContextMenu declaration in your project. This works also for a standalone context menu (for example outside of RadTreeView).

*** Updated on 10.5.2017 ***

New override that works for RadCalendar's Popup, RadTooltip, RadGrid's Column resizing and context menus, RadMenu and RadContextMenu:

<script>

$telerik.getViewPortSize = function () {

var width = 0;

var height = 0;

var canvas = document.body;

if ((!$telerik.quirksMode && !$telerik.isSafari) ||

(Telerik.Web.Browser.chrome && Telerik.Web.Browser.version >= 61)) {

canvas = document.documentElement;

}

if (window.innerWidth) {

// Seems there's no completely reliable way to get the viewport size in Gecko, this should be the best one

// Check https://bugzilla.mozilla.org/show_bug.cgi?id=189112#c7

width = Math.max(document.documentElement.clientWidth, document.body.clientWidth);

height = Math.max(document.documentElement.clientHeight, document.body.clientHeight);

if (width > window.innerWidth)

width = document.documentElement.clientWidth;

if (height > window.innerHeight)

height = document.documentElement.clientHeight;

}

else {

width = canvas.clientWidth;

height = canvas.clientHeight;

}

width += canvas.scrollLeft;

height += canvas.scrollTop;

if ($telerik.isMobileSafari) {

width += window.pageXOffset;

height += window.pageYOffset;

}

return { width: width - 6, height: height - 6 };

}

</script>

The old override below should be replaced by the code above.

<script>

Telerik.Web.UI.RadMenu._getViewPortSize = function () {

var viewPortSize = $telerik.getViewPortSize();

// The document scroll is not included in the viewport size

// calculation under FF/quirks and Edge.

var quirksMode = document.compatMode != "CSS1Compat";

if (($telerik.isFirefox && quirksMode) || Telerik.Web.Browser.edge) {

viewPortSize.height += document.body.scrollTop;

viewPortSize.width += document.body.scrollLeft;

}

else if (Telerik.Web.Browser.chrome) {

viewPortSize.height += Math.max(document.body.scrollTop, document.scrollingElement.scrollTop);

viewPortSize.width += Math.max(document.body.scrollLeft, document.scrollingElement.scrollLeft);

}

return viewPortSize;

};

</script>

<telerik:RadTreeView RenderMode="Lightweight" ID="RadTreeView2" runat="server">

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="RadTreeViewContextMenu1"runat="server" RenderMode="Lightweight">

<Items>

...

*** End of update ***

Solution 2 (for RadContextMenu)
Set EnableScreenBoundaryDetection to false. This will disable the screen boundary detection and some parts of the context menu could be rendered beneath the browser borders when there isn't enough space to be rendered on the visible screen. You will have to use the browser scrollbars to show the hidden part of the menu.

Solution 3 (for RadTooltip)
Use the _getPosRelativeToMouse override to solve the problem:

<telerik:RadToolTipManager ID="RadToolTipManager1" AutoTooltipify="true" runat="server">

</telerik:RadToolTipManager>

<script>

Telerik.Web.UI.RadToolTip.prototype._getPosRelativeToMouse = function (targetBounds) {

var elemX = targetBounds.x;

var elemY = targetBounds.y;

//Get last recorded mouse position

var pos = this._getMousePosition();

var mouseX = pos.clientX;

var mouseY = pos.clientY;

//Take into consideration the offsetScroll!

var standard = $telerik.standardsMode;

//$telerik.standardsMode does not do a good job! Extra check is needed for FF!!

//And yet another check needed for Safari! It should always be set to false in order to get the calculations right

if (!$telerik.isIE && document.compatMode != "CSS1Compat") standard = false;

else if ($telerik.isSafari && !(Telerik.Web.Browser.chrome && Telerik.Web.Browser.version >= 61)) standard = false;

if (standard) {

elemX -= $telerik.getCorrectScrollLeft(document.documentElement);

elemY -= document.documentElement.scrollTop;

}

else //NEW: Add support for quircksmode

{

elemX -= $telerik.getCorrectScrollLeft(document.body);

elemY -= document.body.scrollTop;

}

//Calculate the position of the mouse, relative to the targetcontrol

var deltaX = mouseX - elemX;

var deltaY = mouseY - elemY;

return { x: deltaX, y: deltaY };

}

</script>

Determining the range of the X and Y axis after Zoom

Hello

I would like to know if there is a way to determine the range of the X and Y axis on a "zoomed" graph. Particularly when we draw a box on a chart, is there a way to figure out the X and Y ranges of the zoomed/boxed section on Javascript ?

Thanks !

Changing the labels of x-axis in a scatter line chart

Hi I have defined a programmatically chart as follows:

ASPX Part:

<telerik:RadHtmlChart ID="RadHtmlChartSerie" runat="server" Transitions="true" Skin="Office2007" >

<Appearance>

<FillStyle BackgroundColor="White"></FillStyle>

</Appearance>

<ChartTitle>

<Appearance Align="Center" BackgroundColor="White" Position="Top"></Appearance>

</ChartTitle>

<Legend>

<Appearance BackgroundColor="White" Position="Bottom"></Appearance>

</Legend>

<PlotArea>

<Appearance>

<FillStyle BackgroundColor="White"></FillStyle>

</Appearance>

<XAxis DataLabelsField="Dia">

<LabelsAppearance RotationAngle="90" />

<TitleAppearance Text="Fecha" />

<MajorGridLines Color="#EFEFEF" Width="1"></MajorGridLines>

<MinorGridLines Color="#F7F7F7" Width="1"></MinorGridLines>

<TitleAppearance Position="Center" RotationAngle="0" Text="Día"></TitleAppearance>

</XAxis>

<YAxis>

<LabelsAppearance />

<TitleAppearance Text="Valor" />

<MajorGridLines Color="#EFEFEF" Width="1"></MajorGridLines>

<MinorGridLines Color="#F7F7F7" Width="1"></MinorGridLines>

</YAxis>

</PlotArea>

<ChartTitle Text="Serie Analizada">

</ChartTitle>

</telerik:RadHtmlChart>

And on The server part, add Dynamically a scatter series to the Chart:

CS:

//Declare a ScatterSeries

ScatterSeries pointMinimos = new ScatterSeries();

pointMinimos.Name = "Mínimo";

pointMinimos.Appearance.FillStyle.BackgroundColor = Color.Green;

pointMinimos.LabelsAppearance.Visible = false;

pointMinimos.TooltipsAppearance.DataFormatString = "{1}";

pointMinimos.TooltipsAppearance.Color = Color.White;

//Fills The ScatterSeries

foreach (DataRow dr in dsMaxMin.Tables["dtMinimos"].Rows)

{

ScatterSeriesItem itemCierre = new ScatterSeriesItem(Convert.ToDecimal(dr["X"].ToString()), Convert.ToDecimal(dr["Y"].ToString()));

pointMinimos.SeriesItems.Add(itemCierre);

}

//Add The series to the Chart with XAxis numerical values

RadHtmlChartSerie.PlotArea.Series.Add(pointMinimos);

//Clear the XAxis Items

RadHtmlChartSerie.PlotArea.XAxis.Items.Clear();

//Here the column "Dia" have a date string

foreach (DataRow row in dsMaxMin.Tables["dtMinimos"].Rows)

{

string formattedLabelText = string.Format("{0:MMMM}", row["Dia"].ToString());

AxisItem newAxisItem = new AxisItem(formattedLabelText);

RadHtmlChartSerie.PlotArea.XAxis.Items.Add(newAxisItem);

}

But, the labels on the X Axis dosn't changes , and have the numerical label.

I check the link http://www.telerik.com/help/aspnet-ajax/htmlchart-date-axis.html but only works with databound RadHtmlChart which automatically detects the DateTime object data in the column/field and adjusts the distribution of the items on the XAxis.

There is a way to change the labels once defined the series in the server code?
Thanks A lot¡¡¡

Jorge RR

Problem Viewing Accessed Files from Shared Folder

Greetings,

Since I want to be as short as possible here is the thing...
I implemented File Explorer fetching files from a Shared folder, exactly as this post indicated (post). However while I fetch the data and I can see the file hierarchy and the files, when I am trying to open the files I get this message:

Server Error in '/' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Functions/Ethnological/FileSystemHandler.ashx

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.272

That is a "normal" Http error... Which is pretty weird since, as I said, I can see the files... In the shared folder I have full read/write etc permissions... When I tried accessing these files through a local folder, everything went as expected and I also had preview (which now I do not).

Still, if you want to see the code, just in case here it is...

In .cs

string[] viewPaths = new string[]

{

@"\\cmarinis-pc\ArchiveImages"

};

string[] uploadPaths = new string[]

{

@"\\cmarinis-pc\ArchiveImages"

};

string[] deletePaths = new string[]

{

@"\\cmarinis-pc\ArchiveImages"

};

rfExplorer.Configuration.ViewPaths = viewPaths;

rfExplorer.Configuration.SearchPatterns = new[] { "*.*" };

rfExplorer.Configuration.ContentProviderTypeName = typeof(CustomFileSystemProvider).AssemblyQualifiedName;

In .aspx

<telerik:RadFileExplorer runat="server" ID="rfExplorer" Width="600px" Height="270px"

OnClientItemSelected="OnClientItemSelected">

</telerik:RadFileExplorer>

and the mapping file.

<?xml version="1.0" encoding="utf-8" ?>

<CustomFileBrowserProvider>

<Paths>

<genericHandlerPath>FileSystemHandler.ashx</genericHandlerPath>

</Paths>

<Mappings>

<Mapping>

<PhysicalPath>

<![CDATA[\\cmarinis-pc\ArchiveImages]]>

</PhysicalPath>

<VirtualPath><![CDATA[Shared/]]></VirtualPath>

</Mapping>

</Mappings>

</CustomFileBrowserProvider>

So where could this problem be???

PS: Another crucial, but a little out of the topic matter, is that I want to open .tif images with the explorer. I can open .tif images with the windows photo viewer, but not with the explorer. Any ideas???

Thanks in advance :)
