Chart loosing design on Post Pack

[Imar]

Hi there,

I am using a Spline chart with a theme applied. If a control in the page causes a postback, the lines in my chart change color, resulting in some lines getting almost invisible.

I have created a small demo project demonstrating the problem: http://imar.spaanjaars.com/Downloads/Other/TelerikChartIssue.zip
If you open Default.aspx in the browser, there's a green and a red line. If you choose an item from the DropDownList, the page posts back and the chart changes color.

What do I need to do to fix this?

Also, what do I need to do to change the color of the lines? I changed about a million Appearance properties, but to no avail. Do I  / can I change the skin somehow?

Kind regards,

Imar

Hello Imar,

You can use custom palette to change the lines color:

<telerik:RadChart ID="RadChart1" runat="server" DataGroupColumn="Company" DataSourceID="SqlDataSource1"
            SeriesPalette="MyPalette" DefaultType="Spline" Skin="Vista" AutoLayout="True"
            OnDataBound="RadChart1_DataBound" Width="740">
            <CustomPalettes>
                <telerik:Palette Name="MyPalette">
                    <Items>
                        <telerik:PaletteItem MainColor="Red">
                        </telerik:PaletteItem>
                        <telerik:PaletteItem MainColor="Green">
                        </telerik:PaletteItem>
                    </Items>
                </telerik:Palette>
            </CustomPalettes>
            <PlotArea>
...............

This will also fix the issue with lines losing their colors.

Hi Ves,

Thanks for that; that sorted it out.

Is the fact that the lines change colors a feature or a bug?

H Imar,

That's a bug and I have notified our developers of it, but I am afraid there is no certain time frame for the moment. Your Telerik points have been updated.

No problem. The Palette option worked fine, so at short term, this is not an issue for me anymore.

Kind regards,
