I am using asp.net. It is slow for the built in click for one chart with no javascript or server code for it. It is also very slow, and often times out, when capturing OnLegendItemClick event for one of seven charts to set the legend on the other charts to have the same visibility properties. Is there a way to speed this up?
Here is my javascript for the OnLegendItemClick event.
function OnLegendItemClick(args) {
// hiddenchartClicked prevents any possible looping of click events
// args.preventDefault fixes the problem of the currently clicked item not becoming visible again
// It was making all other charts visible except the clicked one,
// so I set all charts and stopped it from toggling.
if ($('#hiddenchartClicked').val() != "")
return;
var seriesName = args.text;
var visibility = !args.series.visible;
var seriesIndex = args.seriesIndex;
var seriesChart = args.sender.element[0].id
$('#hiddenchartClicked').val(seriesChart);
args.preventDefault();
for (var i = 0; i < 7 ; i++) {
var chartID = "RadDemandChart" + i.toString();
var chart = $find(chartID);
chart._chartObject.options.series[seriesIndex].visible = visibility;
chart.repaint();
}
$('#hiddenchartClicked').val("");
}
Thank you so much.

Hi
I have issues with a filter that i have placed in a radwindow - the dropdowns ect is put behind the window its self - this is my code:
<telerik:RadWindow RenderMode="Lightweight" ID="modalPopup" runat="server" Width="360px" Height="360px" Modal="true" OffsetElementID="main" Style="z-index: 100001;" Skin="Windows7"> <ContentTemplate> <telerik:RadFilter ID="TableEditFilter" runat="server" FilterContainerID="rgTableEdit" ExpressionPreviewPosition="Bottom" Style="z-index: 100002;" /> </ContentTemplate></telerik:RadWindow><script type="text/javascript"> //<![CDATA[ function ShowmodalPopup(sender, args) { $find("<%=modalPopup.ClientID%>").show(); return false; } //]]></script>and is activated by a button click in a GridTemplateColumn:
<telerik:RadButton Image-ImageUrl="~/Images/filter_16x16.png" runat="server" ID="FilterButton" Width="16" Height="16" skin="Windows7" OnClientClicked="ShowmodalPopup" AutoPostBack="false" />
Hi Admin,
i Was trying this demo code ( http://demos.telerik.com/aspnet-ajax/menu/examples/functionality/templates/defaultcs.aspx) for overlay menu. Is that possible to create sub menu for this type of menu ?


Prior to our recent upgrade to 2016.1.113.40 the below chart rendered fine, after our upgrade, we get a JS error. To correct this I had to change the series from LineSeries to a ScatterLineSeries.
Is this a known issue?

Changing the Series to a ScatterLineSeries versus LineSeries seems to have resolved this. I also changed the DataFormatString on the Label to 1.
<Series> <telerik:ScatterLineSeries DataFieldX="Day" DataFieldY="RunningGoalAmount" Name="Monthly Goal"> <Appearance> <FillStyle BackgroundColor="Blue" /> </Appearance> <LineAppearance LineStyle="Smooth" Width="3"/> <LabelsAppearance Visible="false"></LabelsAppearance> <MarkersAppearance MarkersType="Circle" Size="8" /> <TooltipsAppearance Color="White" DataFormatString="{1:C0}"></TooltipsAppearance> </telerik:ScatterLineSeries> </Series> <Series> <telerik:ScatterLineSeries DataFieldX="Day" DataFieldY="RunningTotalAmount" Name="Shipments"> <LineAppearance LineStyle="Smooth" Width="3" /> <LabelsAppearance Visible="false"></LabelsAppearance> <Appearance> <FillStyle BackgroundColor="Red" /> </Appearance> <MarkersAppearance MarkersType="Circle" Size="8" /> <TooltipsAppearance Color="White" DataFormatString="{1:C0}"></TooltipsAppearance> </telerik:ScatterLineSeries> </Series>
