Hi,

The links seems to be working fine.

The interesting thing is the last reply to thread you referenced.

Hi,

 

sorry its took so long to reply been busy!

 

Anyway thanks for your ajax example code it worked great for generating charts on 'postback' after the page has loaded.

 

 

 

However I wanted to generate the chart on 'Page Load' and then on 'Postbacks'

 

 

 

If you use RenderChartHTML on page load then you get the 'click to activate' message in IE.

 

 

 

If you use RenderChart on page load and then RenderChart on postbacks then the postback charts don't display.

 

 

 

However! If you use RenderChart on page load then RenderChartHTML on any postback then all problems are solved.

 

 

 

Not sure if there's an easier way around this but at least it works and I'm happy.

 

 

 

 

 

 

 

 

I have attempted to use this same method and while it does work there remains the issue of the "non-secure items" warning in IE. I am not sure whether the person who posted the quote above regarded that as an issue or not, or even experienced the same behavior I have.

 

 

 

Just my 2 cents.

In the renderChartHTML method code, if you change all http references to https, the security dialog wouldn't appear any more.

When I use the sample code provided with my own charts, it works fine, as long as I am using an XML FILE as the source.  When I try to use and XML STRING, it always gives me the "invalid XML" message.

I've looked for hours at the outputted XML and can find no special characters, missing tags, etc.  When I bring the XML up in an XML editor, there are no problems.

Has anyone else encountered this?  I can provide source code and XML files if necessary.

Thanks.

I'm trying to use one of the charts in my asp.net page and I have this simple code:

 

 

 

 

...

 

using InfoSoftGlobal;

 

 

 

protected void Page_Load(object sender, EventArgs e)

 

{

 

 

 

}

 

 

 

protected string renderChart()

 

{

 

string output = FusionCharts.RenderChart("FusionCharts/FCF_Column3D.swf", "", "Data/Data.xml", "chart1", "350", "440", false, false);

 

 

 

return output;

 

}

 

 

 

protected void btnVisible_Click(object sender, EventArgs e)

 

{

 

string chart;

 

 

 

chart = renderChart();

 

 

 

pollDiv.Visible = true;

 

 

 

panPoll.Controls.Clear();

 

panPoll.Controls.Add(new LiteralControl(chart));

 

}

 

 

 

protected void btnInvisible_Click(object sender, EventArgs e)

 

{

 

pollDiv.Visible = false;

 

}

 

 

 

 

Whenever I load up the page and toggle the visibility all I get is the word "Chart". Any idea why? Also, if I use RenderChartHTML I get "No data to display".

 

Also it doesn't even work if I use the default Data.xml that comes with the charts...so I know it's not that.

 

 

 

EDIT: I got it working.

 

 

 

This line:

 

 

 

string output = FusionCharts.RenderChart("FusionCharts/FCF_Column3D.swf", "", "Data/Data.xml", "chart1", "350", "440", false, false);

 

 

 

Should read:

 

 

 

 

 

string output = FusionCharts.RenderChart("FusionCharts/FCF_Column3D.swf", "Data/Data.xml", "", "chart1", "350", "440", false, false);

 

 

 

As Data.xml is a url not a direct xml string.

Hi,

Could you please use renderChartHTML in Ajax mode?

string output = FusionCharts.RenderChartHTML("FusionCharts/FCF_Column3D.swf", "", "Data/Data.xml", "chart1", "350", "440", false);
