Hello, our company is recently tested products telerik rad scheduler and specifically the need to know if this control can make calls to pop up an external page to insert, edit and delete data, because each process has too many validations directly the database that must be handled by codebehind and for us is very important to use this work scheme.

sorry for my bad English
thanks

Event OnTaskDeleted not fired unless there is only one task

I'm evaluating the RadGantt control for an eventual purshase. I have been able to insert and update tasks but there is a problem with deleting a task. The event OnTaskDelete is not fired unless there is only one task left or I have clicked delete on all tasks. So, if I click to delete only one task and there are more than one task, the confirmation window is showed but the OnTaskDelete event is not fired at all, and the task is not deleted. Is it a know bug? Here's my code:

<telerik:RadGantt ID="RadGantt1" runat="server" AllowTaskDelete="true" RenderMode="Lightweight" DataSourceID="SqlDataSource1" DependenciesDataSourceID="SqlDataSource2"

Change Scale Background

Hello,

I recently upgraded one of our ASP.NET 4 applications from Q2 2014 to the latest 2017 and noticed that the background for the scale changed from gray to white (see attached) and I have not been able to find a way to change it back. I looked within the Telerik demos and found that I'm able to change the BackColor, but it changes it for the entire RadLinearGauge tag. Is there any way to accomplish this?

<telerik:RadLinearGauge ID="radInstalledFE" runat="server" Font-Bold="True" Font-Names="Verdana" Font-Size="10pt" Skin="Office2010Black" Width="420px" ForeColor="Black" Height="90px">

<Pointer Shape="BarIndicator" Value="15" Size="30" Color="#5ca038">

<Track Opacity="0.2" Size="30" Color="Black" />

</Pointer>

<Scale MajorTicks-Size="10" MinorTicks-Size="5" Vertical="False" MinorTicks-Color="Black" MajorTicks-Color="Black" Labels-Color="Black" Labels-Font="Verdana" Labels-Position="Outside" MinorTicks-Visible="False"></Scale>

</telerik:RadLinearGauge>

Batch Editing - Cascading Lists

Hi,
I would like to create a batch edit grid where the first two columns are a pair of cascading combo boxes (actually the first column needs to be a combo, the next column can be a combo or just a dropdown list). I've had a few experimental attempts so far but have not been able to get anything to work properly. Before I go any further, I would like to ask what is the best way to tackle this problem?

The application I'm trying to write is a timesheet module. The idea is that at the end of the week, the user will enter a row on their timesheet for each job (selected from the combo box) they worked on. Then they will select a task (each job is broken down into a number of tasks) from the next combo/dropdown. Then in the next seven columns, they will enter the number of hours worked on that job/task against each day.

The list of jobs and their related tasks is being queried from a SQL database and I've tended to use asp:SqlDataSource controls to supply the data to the page. I'm OK with batch editing generally but the cascading lists has me stumped so any help would be much appreciated.

Regards Geoff

Barcode as Image

Love the new barcode control. QR is great.

I'm trying to setup a generic barcode generator that can be used through out my app (http://whatever/barcode.aspx?value=xyz) and have it generate a PNG image. I know in the Q2 release this was not possible since PNG was not supported. However now that it is, I would love a few suggestions on how I could render the barcode image in code-behind (C#) and then just stream it out to the browser.

Basically I just need to be able to get to the PNG image for the barcode from the control.

Thanks,
Alex

RadPageLayout still has problems in design mode

I just installed the new release of telerik asp.net ajax (2014 q2) and I was hoping that they fixed some annoying problems in design mode !
The RadPageLayout still has problems in design mode, In fact, the message appears: "Error Rendering Control. An unhandled exception has occurred. Request is not available in this context" .
This problem prevents us from seeing the contents within the control and prevents change in design mode the control properties.

I hope this problem will be solved as soon as possible because it greatly penalizing !!!

Thanks in advance

How to add Additional Fields of type AsyncUpload or input[type=file] ?

Hi,

For each uploaded file, I would like to add one or multiple additional field(s) which would be a file (so the goal is to add either a basic input[type=file] or a Telerik AsyncUpload).

How to achieve this ?

I got to add input[type=file] additional fields but the files are not posted and I can't get the binaries on the server side.

ListFiles(i).GetFieldValue("additionalFileInput") returns a string that is the selected file name.

How could I get the binaries from additional fields that are file inputs ?

way to make graph axes cross at (0,0)

Is there any way I can make attached graph axes cross at (0,0)? The left most point is 299, the right most is 292, so there is a little change over these 5 years, but the graphic looked like graph is going off a cliff

Here is my current setup
