Login.aspx:759 Uncaught ReferenceError: Telerik is not defined

I went to update one of our Web Apps on our testing server and all of a sudden I started getting the "Uncaught ReferenceError: Telerik is not defined" Error. The server is running MWS 2003 R2. IIS is 6. .net runtime version is 4.0. Telerik version is 2016.2.504.40

I know this has something to do with the Telerik.Web.UI.WebResource.axd file but for the life of me I can't put my finger on it. Here is my web.config file:

Browser Back Button Navigation for Dynamically Loaded User controls in a TabStrip

Hello,

I have created an application that uses the TabStrip. My application has a Master Page that loads the ASPX page containing the TabStrip. I have a RadScriptManager and a RadAjaxManager (EnableAJAX is set to 'true') in my MasterPage. I've set the "EnableHistory" to "true" for the RadScriptManager, and when the user clicks on a Tab, within the TabClick event, I add a HistoryPoint that stores the Tab's "text" value. Withing the "OnNavigate" event for the RadScriptManager I can find the TabStrip and MultiPage controls, and I can find the Tab from it's text. However, when I set the "selected" property of the tab to 'true' nothing happens. The tab does not get loaded. What am I doing wrong? Is there a better way to achieve browser's "Back-button" navigation for the TabStrip that's been ajaxified?

Sample Code:

OnNavigate event for the RadScriptManager:

protected void rsmSiteMaster_Navigate(object sender, HistoryEventArgs e)

{

string backPage = Server.HtmlEncode(e.State["BackNavigation"]);

ContentPlaceHolder cphTabStrip = (ContentPlaceHolder)Page.Master.FindControl("cphTabStrip");

RadAjaxLoadingPanel alpTabStrip = (RadAjaxLoadingPanel)Page.Master.FindControl("alpTabStrip");

RadTabStrip rtabstripTabs = (RadTabStrip)cphTabStrip.FindControl("rtabstripTabs");

RadMultiPage rmpTabStrip = (RadMultiPage)cphTabStrip.FindControl("rmpTabStrip");

RadTab tab = rtabstripTabs.FindTabByText(backPage);

tab.Selected = true;

tab.DataBind();

}

This is how I set the HistoryPoint withing the "TabClick" event:

string key = "BackNavigation";

RadScriptManager.GetCurrent(this).AddHistoryPoint(key, e.Tab.Text);

Thanks,

Shawn A.

Additional X axis labels

I am using the RadHtmlChart control. I have set the X axis title, as shown below. But in addition to that, I want each column to have its own title or label on the X axis. Is that possible? I can see that the RadHtmlChart control supports 2 Y axes, but it does not appear to support 2 X axes. If it did, I could use the second X axis to display the additional axis labels.

Multi column Grid header

Hi Team,

I've two questions.

1) I'm trying to create a radgrid header with multiple columns grouped under a column,similar like below link.

http://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/multi-column-headers/defaultcs.aspx

</ColumnGroups>

I'm getting this below error. I'm using Ajax controls Telerik.Web.UI, v.2011.3.1305.40 (Dev), do this version of telerik controls supports this feature or not?

Please suggest some alternative approach.

Type 'Telerik.Web.UI.GridTableView' does not have a public property named 'ColumnGroups'.

2) An alternative for that in Header template I designed a HTML table.

<telerik:GridTemplateColumn UniqueName="TemplateColumn" HeaderStyle-Width="250px" AllowFiltering="false" >

<HeaderTemplate>
<table>
<tr>
<td colspan="8" style="text-align:center;>
<asp:Label ID="Label10" runat="server" Text=" Unweighted Savings" ></asp:Label>
</td>
</tr>
<tr>
<td>
<asp:LinkButton ID="LinkButton2" runat="server" Text=" C&S " CommandName='Sort' CommandArgument='CS' Font-Underline="true"></asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LinkButton1" runat="server" Text=" M&R " CommandName='Sort' CommandArgument='MR' Font-Underline="true"></asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LinkButton3" runat="server" Text=" E&I " CommandName='Sort' CommandArgument='EI' Font-Underline="true"></asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LinkButton4" runat="server" Text=" Public Exchange " CommandName='Sort' CommandArgument='Exchange' Font-Underline="true"></asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LinkButton5" runat="server" Text=" Private Exchange " CommandName='Sort' CommandArgument='PrivateExchange' Font-Underline="true"></asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LinkButton6" runat="server" Text=" Total " CommandName='Sort' CommandArgument='Total' Font-Underline="true"></asp:LinkButton>
</td>
</tr>
</table>
</HeaderTemplate>
<ItemTemplate>
<table>
<tr>
<td>
<asp:Label ID="Label4" Text='<%# Bind("CS") %>' runat="server" ></asp:Label>
</td>
<td>
<asp:Label ID="Label5" Text='<%# Bind("MR") %>' runat="server" ></asp:Label>
</td>
<td>
<asp:Label ID="Label6" Text='<%# Bind("EI") %>' runat="server" ></asp:Label>
</td>
<td>
<asp:Label ID="Label7" Text='<%# Bind("Exchange") %>' runat="server" ></asp:Label>
</td>
<td>
<asp:Label ID="Label8" Text='<%# Bind("PrivateExchange") %>' runat="server" ></asp:Label>
</td>
<td>
<asp:Label ID="Label9" Text='<%# Bind("Total") %>' runat="server" ></asp:Label>
</td>
</tr>
</table>
</ItemTemplate>
</telerik:GridTemplateColumn>

I'm getting my desired output, but when i sort any column , entire column is not highlighted and up/down arrow is not coming.

Unable to filter these columns. inside header template.

Regards

Sai Teja

Download Link

I'm trying to set up a download link button, but it seems impossible. I keep getting the following error:

InnerException: Cannot convert object of type 'System.Int32' to type 'System.Collections.IDictionary'

FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal
StackTrace:
Message: DotNetNuke.Services.Exceptions.PageLoadException: Cannot convert object of type 'System.Int32' to type 'System.Collections.IDictionary' ---> System.InvalidOperationException: Cannot convert object of type 'System.Int32' to type 'System.Collections.IDictionary' at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input) at Telerik.Web.UI.GridCommandEventArgsFactory.CreateGridCommandEventArgs(GridItem item, Object commandSource, CommandEventArgs originalArgs) at Telerik.Web.UI.GridItem.OnBubbleEvent(Object source, EventArgs e) at System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

This is from DotNetNuke's Log Viewer. I have a user control with a RadGrid that contains the RadButton(s) I'm using to make the download links. This control is loaded in various places that wrap the control with an RadAjaxPanel. Even when I switch it to a Panel ajaxified by a RadAjaxManager this issue appears. What does this error mean? I have no means of debugging it.

Cannot add more than one line in a chart

I populate a Dataset whith multiple data tables of results, and then I loop through each of the tables to reveal my results.

However only the first datatable is used the others are ignored.

I have made sure that the lineseries name is the same as the datatable ?

Any ideas please ??

foreach (DataTable table in myRunData.Tables)
{

LineSeries currentLine = new LineSeries();
lineSeries1.Name = table.TableName;
lineSeries1.LabelsAppearance.Visible = true;
lineSeries1.LabelsAppearance.DataFormatString = "y";

lineSeries1.TooltipsAppearance.Color = System.Drawing.Color.Blue;
lineSeries1.TooltipsAppearance.DataFormatString = "{0}";

lineSeries1.DataFieldY = "TimeInSeconds";

lineSeries1.TooltipsAppearance.ClientTemplate = " #= kendo.parseInt(value/60) #:#= (value%60) # minutes";
lineSeries1.LabelsAppearance.ClientTemplate = " #= kendo.parseInt(value/60) #:#= (value%60) # minutes";

lineSeries1.TooltipsAppearance.DataFormatString = "{0:hh:MM:ss}";
RadHtmlChart1.PlotArea.Series.Add(lineSeries1);
}
RadHtmlChart1.DataSource = parkRunData;
RadHtmlChart1.DataBind();
if (!RadHtmlChart1.Visible)
{
RadHtmlChart1.Visible = true;
}

Telerik RadHtmlChart Y Axis labels as seconds but showing time

I have a line graph
The Y axis are time in seconds.

What I want is the legend for each point to be time not seconds

lineSeries1.TooltipsAppearance.DataFormatString = "{0}";

its just coming up with numbers though :(
also is there any way of formatting the Y axis, so that instead of seconds I get
5:00 10:00 15:00 20:00 25:00
etc ? which relates to
500 seconds 1000 seconds 1500 seconds 2000 seconds
etc
The data is fed in using a datatable in code behind so dont really want to hard code the times as they could be very variable.
foreach (DataRow row in dt.Rows){CategorySeriesItem item1 = new CategorySeriesItem(); item1.Y = int.Parse(row["TimeInSeconds"].ToString()); lineSeries1.SeriesItems.Add(item1);}
This draws the point, but what I want to be able to do is set the legends and labels for the time
