Removing unnecessary attributes and elements

[JT]

How can I disable RadChart from rendering a style, the javascript onerror call, and the additional script block.  I want to simply show a RadChart that does not involve any further user interaction nor postbacks.

For example, here's what my RadChart outputs:

<div id="ctl04_BarCharts_ctrl1_BarChart" class=" RadChart" style="height:44px;width:293px;">
    <img alt='' style='border-width: 0px;'  src='ChartImage.axd?UseSession=true&amp;ChartID=530d344a-c0c1-408c-b083-88a56c512866_chart_ctl04$BarCharts$ctrl1$BarChart&amp;imageFormat=Png&amp;random=0.0234165825058783' onerror="if(confirm('Error loading RadChart image.\nYou may also wish to check the ASP.NET Trace for further details.\nDisplay stack trace?'))window.location.href=this.src;" /><input id="ctl04_BarCharts_ctrl1_BarChart_ClientState" name="ctl04_BarCharts_ctrl1_BarChart_ClientState" type="hidden" />
</div><script type="text/javascript">
//<![CDATA[
    Sys.Application.add_init(function(){});
//]]>
</script>

and here's what I'd like it to output:

<div id="ctl04_BarCharts_ctrl1_BarChart" class=" RadChart">
    <img alt='' src='ChartImage.axd?UseSession=true&amp;ChartID=530d344a-c0c1-408c-b083-88a56c512866_chart_ctl04$BarCharts$ctrl1$BarChart&amp;imageFormat=Png&amp;random=0.0234165825058783' />
</div>

or better yet:

    <img alt='' src='ChartImage.axd?UseSession=true&amp;ChartID=530d344a-c0c1-408c-b083-88a56c512866_chart_ctl04$BarCharts$ctrl1$BarChart&amp;imageFormat=Png&amp;random=0.0234165825058783' />

Hello JT,

The onerror call is only generated in debug mode. Once you deploy your app in production it will not get generated. Also, if you disable the ClientSettings ant AutoPostBack=false you will have less markup generated.

Kind regards,

Thanks for the response Vladimir.  Setting debug to false in the config did the trick for the javascript onerror.
How can I disable ClientSettings and where is the AutoPostBack property for RadChart?

Hi JT,

About the ClientSettings, you simply don't need to have such a tag in your .aspx file. If you have it then make sure that ClientSettings.ScrollMode is ChartClientScrollMode.None.

About the AutoPostBack functionality, I incidentally misled you. If you are not using any client-side scrolling and zooming (see above), and don't have any click events wired RadChart will automatically not render any javascript.

Best wishes,
