How to dynamically set plotbands for HTML Chart when xaxis are dates

I have a HTML Chart that works great to plot Line Series data against hourly date/time values in the X axis. I want to shade weekend dates based on the selected date range. So this needs to be done dynamically in code. I suspect that I'm not setting the From/To values correctly. I found one reference that suggested that these should be in OADate format. But this doesn't seem to work. But there may be other issues that I'm not seeing. Here is my code. Any help is greatly appreciated.

Here's the relevant Markup

<telerik:RadHtmlChart runat="server" Width="1000px" Height="300px" BackColor="AntiqueWhite" PlotArea-XAxis-LabelsAppearance-TextStyle-FontSize="9pt"

ID="rhcLogsLast24hrs" BorderWidth="1" >

<PlotArea>

<Series>

<telerik:LineSeries DataFieldY="LogParserSuccess" Name="Log Parser" >

<TooltipsAppearance Color="White" DataFormatString="{0:n0}"/>

<LabelsAppearance Visible="False" DataFormatString="{0:n0}" />

<Appearance FillStyle-BackgroundColor="#5ab7de">

<FillStyle ></FillStyle>

</Appearance>

<LineAppearance Width="1" />

<MarkersAppearance MarkersType="Circle" BackgroundColor="White" Size="8" BorderColor="#5ab7de"

BorderWidth="2"></MarkersAppearance>

<TooltipsAppearance Color="White">

<ClientTemplate>

#=dataItem.LogParserSuccess# Million Log Events Parsed on<br />#=dataItem.Hour#

</ClientTemplate>

</TooltipsAppearance>

</telerik:LineSeries

</Series>

<XAxis DataLabelsField="Hour" >

<LabelsAppearance RotationAngle="90" DataFormatString="{0:M/d h tt}">

</LabelsAppearance>

<TitleAppearance Text="Hour">

</TitleAppearance>

</XAxis>

<YAxis>

<LabelsAppearance DataFormatString="{0:n0}" >

</LabelsAppearance>

<TitleAppearance Text="Log Events" >

</TitleAppearance>

</YAxis>

</PlotArea>

<Legend >

<Appearance Visible="True" Position="Right">

</Appearance>

</Legend>

<ChartTitle Text="Log Events">

</ChartTitle>

</telerik:RadHtmlChart>

Here is the relevant Code Behind:

rhcLogsLast24hrs.PlotArea.XAxis.LabelsAppearance.DataFormatString = "{0:M/d h tt}"

rhcLogsLast24hrs.PlotArea.XAxis.TitleAppearance.Text = "Hour"

rhcLogsLast24hrs.PlotArea.YAxis.TitleAppearance.Text = "Log Events (Millions)"

If ts.TotalHours > 24 Then

rhcLogsLast24hrs.PlotArea.XAxis.LabelsAppearance.Step = ts.TotalHours / 20

End If

Dim I As Integer = 0

For Each dr As DataRow In dt.Rows

Dim thisdate As DateTime = dr("Hour")

If thisdate.DayOfWeek = DayOfWeek.Saturday Or thisdate.DayOfWeek = DayOfWeek.Sunday Then

Dim band As PlotBand = New PlotBand()

band.Color = System.Drawing.Color.Green

band.Alpha = 190

band.From = thisdate.ToOADate

band.To = thisdate.AddHours(1).ToOADate

rhcLogsLast24hrs.PlotArea.XAxis.PlotBands.Add(band)

End If

I += 1

Next

rhcLogsLast24hrs.DataSource = dt

rhcLogsLast24hrs.DataBind()

Thanks!

RadEditor problem when hyperlink contains >

Hi,

First the problem occurs in IE not in Firefox.

I have this string in html view: <a href="http://TEST?TestId=<%TEST_GUID%>">here</a>

In Firefox it looks like this:

HTML View: <a href="http://TEST?TestId=<%TEST_GUID%>">here</a>
Switch to design: here
Switch to HTML: <a href="http://TEST?TestId=<%TEST_GUID%>">here</a>

In IE 11

HTML View: <a href="http://TEST?TestId=<%TEST_GUID%>">here</a>
Switch to design: ">here
Switch to HTML: <a href="http://TEST?TestId=<%TEST_GUID% originalAttribute=" href"="" test?testid='<%TEST_GUID%"'>">here</a>

As you can see editing this in IE alway crashes the hyperlink.

Is there any way to fix this?

Telerik in IE 9

We wrote this web page using telerik controls and for some reason, it won’t work in IE 9.

The issue is a display issue. The google map won’t load and the entire box displays in half size (only in IE9) It works in every other browser including IE 7 and 8. We upgraded to the latest Telerik DLLs ( I believe). We are looking for a fix or direction on how to get this resolved in IE9.

Here is the page in question: http://www.alarm.org/Search/MapSearch.aspx?ZipCode=75248

Thanks for your help!

getTextElement is null

Sometimes I got javascript error (I translated error message by myself from polish):

err_msg = Could not get property „getTextElement” for not defined or null reference (line 16762)

documentState = completed

url = .../Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35:pl-PL:7dd8b7c5-dd18-48e6-97c2-5a5a060b2752:ea597d4b:b25378d2;Telerik.Web.UI:pl-PL:ead0d100-d31b-4d13-9451-88908208aae7:16e4e7cd:f7645509:22a6274a;||:4c5db2b2:de3312b1:eff1b1fc;Telerik.Web.UI, Version=2015.2.729.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4:pl-PL:ead0d100-d31b-4d13-9451-88908208aae7:24ee1bba:c128760b:874f8ea2:19620875:4877f69a:f46195d3:92fe8ea0:fa31b949:490a9d4e:bd8f85e4:cda80b3:383e4ce8:e330518b:2003d0b8:88144a7a:1e771326:c8618e41:1a73651d:333f8d94:ed16cbdc:e524c98b:b7778d6c:6d43f6d9:407acb1c:e4f8f289

I could not reproduce it while developing, but on production this error appears quite often. I suppose that mentioned Javascript code tries to refer to control (button) when it is not rendered yet, but I have no idea how to resolve it.
