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;
            }

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

So I'm using the RadScheduler control with WebApi and my appointment records come back from the server as iso 8601 strings like "2016-03-01T04:00:00Z". All dates that come from the server are in UTC format, and the RadScheduler control is set to render appointments using UTC time. So essentially if an appointment comes from the server as 8am UTC, then it should render at 8am on the scheduler, regardless of what timezone the client computer is set to.

Now there's an edge case that breaks the rendering of appointments. During the first X hours of the first day of a month, if an appointment starts within the first X hours, the parsing for the start time string fails and the appointment does not show up on the scheduler. The value X is the absolute value of the timezone offset for the client machine. So for instance if the machine is set to -5 hours offset, then appointments within the first 5 hours will not show up.

I've narrowed down the problem to the fact that the Telerik.Web.UI.Scheduler.Rendering.parseISO8601 function does not return a valid Date object in this scenario. You should be able to replicate this easily by executing Telerik.Web.UI.Scheduler.Rendering.parseISO8601("2016-03-01T04:00:00Z") assuming you have the Telerik.Web.UI.Scheduler.Rendering namespace / class loaded. It will return an invalid date if the client timezone offset is -5 or greater (-6, -7, etc..).

Is this a known issue and is there a fix?

Hello experts... I need help please.

I have a RadGrid with multiple row edit... I want to open all checked Items in a popup when I click the edit button.

I thought I do it with <NestedViewTemplate> or with another RadGrid2. I have no idea about how do I solve this problem. Can you please give me feedback.

????

}

when I checked Items it shold come the checked Items in Popup and edit.

I would be glad about your help.

Thanks a lot.

I'm looking for a way to prevent a task from becoming a summary (by adding tasks, or moving/dropping tasks, as children) if certain conditions exist on that task.  For instance, if a task has had time reported against it, it cannot become a summary.

Can I prevent all the CRUD operations on the Gantt based on checking for a condition on the task that would become a summary?  Can I return the data to check as part of the Gantt query? Or would this have to be outside the control?

Thanks for any help or hints

Hi,

I'm quite new to the Telerik framework, but I've found some strange behaviour(s) when using buttons.

I've got a RadGrid with an edittemplate that expands when a user clicks the editcolumn of a row he wishes to edit.

In this edittemplate I have a few textfields, dropdowns and buttons (checkboxes).

Strangely enough the buttons are acting somewhat strange; my project manager wants me to use the classic rendertype - but when using the classic rendering I seem to have a checkbox in the checkbox (meaning that I have another box inside the box that is left of the text of said checkbox). 

If I however go for a lightweight rendering it seems fine, until I check the box once which then expands the width of the checkbox. 

Here are some snippets of the code:

<div style="margin-top:10px;">
                                   <telerik:RadButton ID="RbtnShow" RenderMode="Auto" runat="server" ToggleType="CheckBox" ButtonType="StandardButton" style="margin-right:203px;">
                                       <ToggleStates>
                                           <telerik:RadButtonToggleState Text="Show On Report" PrimaryIconCssClass="rbToggleCheckboxChecked" />
                                           <telerik:RadButtonToggleState Text="Show On Report" PrimaryIconCssClass="rbToggleCheckbox" />
                                       </ToggleStates>
                                   </telerik:RadButton>

                                   </telerik:RadButton>
                                          <telerik:RadLabel runat="server" ID="RlblDate" AssociatedControlID="RtxtDate" Text="State Date:" style="margin-right:38px;" />
                                            <telerik:RadTextBox ID="RtxtDate" runat="server" width="130px">
                                            </telerik:RadTextBox>
                                       </div>

                                 <telerik:RadButton ID="RbtnKey" runat="server" ToggleType="CheckBox" ButtonType="StandardButton" width="110px"  

                                                                style="margin-right:200px;">
                                       <ToggleStates>
                                           <telerik:RadButtonToggleState Text="Key Issue" PrimaryIconCssClass="rbToggleCheckboxChecked" />
                                           <telerik:RadButtonToggleState Text="Key Issue" PrimaryIconCssClass="rbToggleCheckbox" />
                                       </ToggleStates>
                                   </telerik:RadButton>

I'll attach a picture so you might understand it better.

My Radupload control is not remebmering the value on post back and therefore loosing its value to upload the files.

        <telerik:RadAsyncUpload ID="rdFileUploads" TargetFolder="~\uploads\" MultipleFileSelection="Automatic" runat="server"></telerik:RadAsyncUpload>
                          

Hi Telerik Team,
