property '_continuousEvents'

Hello,

I'm using scheduler timeline (http://demos.telerik.com/kendo-ui/scheduler/timeline).

When i try to add some dynamic data to scheduler datasource and resources, chrome console returns me error "Uncaught TypeError: Cannot read property '_continuousEvents' of undefined"

var s = $("#appointmentScheduler").data('kendoScheduler');

var d = {

AppointmentId: data.GetAppointmentsForContactsResult.AppointmentData[i].AppointmentId,

title: data.GetAppointmentsForContactsResult.AppointmentData[i].Title,

datas: data.GetAppointmentsForContactsResult.AppointmentData[i].Data,

start: parseDateFromWCF(data.GetAppointmentsForContactsResult.AppointmentData[i].StartDate),

end: parseDateFromWCF(data.GetAppointmentsForContactsResult.AppointmentData[i].EndDate),

endTimezone: undefined,

startTimezone: undefined,

recurrenceException: undefined,

recurrenceRule: undefined,

description: undefined

};

s.dataSource.add(d);

var tmp = [];

tmp.push(self.contacts());

tmp.push(selected);

self.contacts(tmp);

self.groupDataSourceUpdate();

s.resources[0].dataSource.data(self.groupingDataSource());

s.refresh();

Filled data looks like:

var d = {

AppointmentId:10,

title: "test",

datas: [3],

start: Tue Dec 22 2015 13:00:00 GMT+0100 (Central European Standard Time),

end: Tue Dec 22 2015 14:00:00 GMT+0100 (Central European Standard Time),

endTimezone: undefined,

startTimezone: undefined,

recurrenceException: undefined,

recurrenceRule: undefined,

description: undefined

};

s.dataSource.add(d);

var tmp = [];

tmp.push(self.contacts());

tmp.push([{text: "test", value: 3}]);

self.contacts(tmp);

self.groupDataSourceUpdate();

s.resources[0].dataSource.data(self.groupingDataSource());

s.refresh();

Donut chart not displaying % correctly

Hi,

Please look at the markup for the donut chart:

<telerik:RadHtmlChart runat="server" ID="DonutChart1" Height="600px" Width="600px" OnClientSeriesClicked="OnClientSeriesClicked">

<ChartTitle Text="Deficiencies by Risk Rating" />

<PlotArea>

<Series>

<telerik:DonutSeries DataFieldY="Size" NameField="State" ExplodeField="IsExploded">

<TooltipsAppearance DataFormatString="{0}%"></TooltipsAppearance>

</telerik:DonutSeries>

</Series>

</PlotArea>

</telerik:RadHtmlChart>

I then bind this in the page_load event to a datasource that is a collection of my custom entity.

protected void Page_Load(object sender, EventArgs e)

{

DonutChart1.DataSource = ReportingBLL.GetDepartmentPieChartDataByPriority();

DonutChart1.DataBind();

}

When I look at the chart I see 3 slices. 1st Slice shows 63%, second 1% and the third 1%. As you can see that does not add up to 100%. I have debugged the code and verified that the collection has 65 items, with one portion containing 63, second 1, and last 1 item. It appears as if instead of showing % it is just displaying the totals.

How do I get it to display the %?

client side find control in antoher user control

Hello,

I am using the client object model. I have a page with 3 user controls. I have JavaScript in UserControl1 that needs a reference to a TreeView control which resides in UserControl2. Can I do that?

Secondly, I have the option of removing the User Controls and just using the page (aspx) would that save me compilcations later?

Updated** Attempt2 works:

// attempt1: does not resolve at compile time

var tree = $find("<%= RadTreeViewCommands.ClientID %>");

// attempt2: radTreeViewCommandsClientID is a global variable we set on the server

var tree = $find(radTreeViewCommandsClientID);

Filtering expression with '%'

Greetings,

I was trying to use the Contains filter with a value containing a '%' char in hte middle of value but no success. The settings are:

EnableLinqExpressions="False"
The columns are generated programatically

What I'm trying to filter is something like:

([description] like '%apple%juice%') to bring values like "green apple juice" or "apple juice box" or even "yadda apple whatever juice" (sorry for the bad example)

The filter expression when I enter "apple%juice" in the filter item is generated like that example but the filter doesn't work. Is this approach possible or simply can't be done?

Set Client Events On Request Start with Ajax Manager Proxy

Hello,

I am following one of your demos on how to export radGrid data to PDF. http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/exporting/pdf-export/defaultcs.aspx

After following the demo I ran into an issue where nothing would happen after clicking the "downloadPDF" button. After some research I came to learn that this may be caused by an AJAX issue because the page needs to return stream rather than XttpRequest used for AJAX.

The proposed solution (which is outlined in your demo) is to add a block of javascript code to the page like this:

<script type="text/javascript">

function requestStart(sender, args) {

if (args.get_eventTarget().indexOf("btnDownloadPDF") > 0)

args.set_enableAjax(false);

}

</script>

The problem I am having is that I must somehow tie this function to the AjaxManager's ClientEvents-On-RequestStart attribute, but I am using an AjaxManagerProxy (since we already have an AjaxManager on the master page) and the AjaxMangerProxy does not seem to posses such a client side setting.

Please advise on how I can set this value for ClientEvents-On-RequestStart for an AjaxManagerProxy?

Thanks in advance,
Justin

radgrid export to excel biff format

Hi,

I've the below format in my aspx:

</ExportSettings>

I need to do the foll:
1) When exporting to excel, how do I left justify the header and excell cell contents .(i've biff formatting. I cannot change it to html due to excel warning message.)

I tried this in itemCommand:

GridItem

Item = (GridItem)radDASignature.MasterTableView.GetItems(GridItemType.Item)[0];

foreach (TableCell tcell in Item.Cells)

{

tcell.Text = tcell.Text.Replace(

"<nobr>", "");

tcell.Style[

"text-align"] = "left";

tcell.HorizontalAlign =

HorizontalAlign.Left;

}
This above doesn't work. Please help with code.

2) When exporting the cell content in excel,I have <nobr> and </nobr> tags to the data. How do I get rid of them while exporting.
I set them in column created event to avoid wrapping of cell contents. However, I do not want the <nobr> added to the excel data while exporting.
