Hi we are evaluating telerik controls for use in our application.

Problem:   The series won't change colors when the color is set at runtime.



Background:
I'm using ChartFX Winforms 2009 Q2

I am creating a solution where a chart is embedded in a Grid cell. 
I use the grid.cellformatting event to set the grid image if the rowinfo tag has not been set, much like is suggested in the telerik sample for: Multiple child views with RadGridView for WinForms

To simplify the test, I just default the series bar value to: "series.Appearance.FillStyle.MainColor = Drawing.Color.Green " (see bulleted line in code block below)

Eventually I need to add a piece of code that will set the series color based on the value.  For now I have just defaulted the value to show as green.

I have referenced other posts in the forum and added the lines to updategraphics, refresh, and still could not get the series to turn green.

Code:

GridToleranceChart is a usercontrol that has a radchart on it.  I use an instance of this usercontrol, and reference its public chart property, so I could set some visual elements at designtime.  PrepareChart is called when the form loads.

Your help is greatly appreciated.

Incorrect behavior of the line at the beginning and at the end at identical values

Hi,

I'm trying to programmatically change the fill colour of the series on my chart and for some reason I'm not getting it to work.

This is the code I'm currently using.


Obviously I'm either missing something or the above code is completely wrong, can someone help please?

Regards,

Guy

I'm using RadChart v2011.3.11.1219 with a .Net 4.0 WinForms app using VS 2010 sp1. In this app I am displaying a couple of charts, but I am wondering if it is possible to generate a line chart and save it to png without ever displaying the chart?

How would I go about doing that?

Hello Team Telerik,

I want to ask how can I have a 3D chart. How can I do this?

Is there a property which set the chart in a 3D mode?

Another Problem I have is that I cant add a radLabel to a radGroupBox programatically.

Thanks very much

Kind regards,

Alfonsina

Am I looking in the wrong place or what is going wrong.

Hi all

I have three questions:

First :I use telerik chart to create a chart for my
application. I want to insert column and row sum of chart data table below the
chart (the same as last column and row in attached image).I do it manually. Is
it possible to do it automatically?

Second:As you can see in the attached image, The last column
is the total sum of row.Is it possible that the last column shows just the
value not bar chart?

 

Third:is it possible to remove colored bullet  of total last row  from legend?

Is it possible to allow a user to choose the chart type at run time, say from a drop down box.

I am using an older version of the RadControls (2011.3.1115.40). I would like to save the charts to jpeg format. I have a button on the form which invokes the following event: 

        protected void btnSaveChar_OnClick(object sender, EventArgs e)
        {
            RadChart1.Save(Server.MapPath("~/files/chart.jpg"), System.Drawing.Imaging.ImageFormat.Jpeg); 
        }
This definitely saves the chart, but its a blank chart with the label "There is no or empty series". What do I need to do to save the chart as it is displayed on the webform? 

Thanks! 

I have a Windows Forms application (C# .NET 3.5) which uses RadChart and RadMenu controls (version 2009.1.9.311).  I can build and run the application on the build machine (Windows 7 64-bit), but it crashes immediately when run it on any other Windows 7 64-bit PC.  I created a new test application with nothing except one RadChart and it also crashes immediately.  As soon as I click on the executable it displays the standard Windows "[program] has stopped working" error with the choice to check online for a solution or close the program.  The original application has the following details "Problem Event Name: APPCRASH; Fault Module Name: KERNELBASE.dll; Fault Module Version: 6.1.7600.16385; Exception Code: e0434f4d; Exception Offset: 000000000000aa7d; OS Version: 6.1.7600.2.0.0.256.4".  The test application only as a few details which might be useful: "Problem Event Name: CLR20r3; Problem Signature 03: 4call1179b; (PS 06 is the same); Problem Signature 07: 1; Problem Signature 08: 15; Problem Signature 09: System.IO.FileNotFoundException; OS Version: 6.1.7600.2.0.0.256.4".  I can create a similar test application with non-Telerik controls and do not get the error on other Win 7 x64 PCs.

Has anyone else experience similar issues?  Is there a solution / workaround?

Thanks,
Chris
