A problem AjaxMethod and AjaxEvent

[heysol]

hi

I want to load a graphic. the question is : i place my function in the page_load and works great. i want to do the same with a button but it doesn´t modify the graphic i did it with Microsoft Ajax and placed the button into an update panel and updated it. Is there something similar for Coolite or a property because i did it with and AjaxMethod and AjaxEvent and didn´t modify the chart.

[AjaxMethod]
public void LoadData()
{
  //these are the params for the linear graphic
  double[] yval1 = { 15, 24, 38, 4, 59 };
  string[] xval1 = { "john", "Mary", "Ralph", "Betty", "Morphy" };
  Chart1.Series["Series1"].Points.DataBindXY(xval1, yval1);
}

Aspx code for tha AjaxMethod:

<ext:Button ID="Button1" runat="server" Text="Carga Encuesta" Icon="Accept">
 <Listeners>
  <Click Handler="Coolite.AjaxMethods.LoadData();" />
 </Listeners>
</ext:Button>

public void LoadData()
{
  //these are the params for the linear graphic
  double[] yval1 = { 15, 24, 38, 4, 59 };
  string[] xval1 = { "john", "Mary", "Ralph", "Betty", "Morphy" };
  Chart1.Series["Series1"].Points.DataBindXY(xval1, yval1);
}

<ext:Button ID="Button1" runat="server" Text="Accept" Icon="Accept">
 <AjaxEvents>
   <Click OnEvent="Button1_Click">
     <EventMask ShowMask="true" MinDelay="300" Msg="Loading..."   />
   </Click>
 </AjaxEvents>
</ext:Button>

Hi,

MS Graph render as image therefore you can't update it during ajax event.
I can suggest next solution:


1. Define MS Grap control in different page and set for it *RenderType="BinaryStreaming", It should be single control on page
***<%@ Page Language="C#" %>
** <asp:Chart id="Chart1" runat="server"*
** * * *RenderType="BinaryStreaming"
** * * * * ....


2. Add to page image tag
** **<img id="chart" />


3. For update image use the following function
** * * *var reloadImage = function() {
** * * * * *Ext.fly('chart').dom.src = String.format('getImage.aspx/?t={0}', new Date().format('U'));

** * * *}
t - query string parameter which allows to avoid caching

Thanks it works but i wanna do the same too with a Dundas Chart http://www.dundas.com/ it sent a weird code maybe it comes from the image i don´t know maybe i´m doing something wrong i did exactly you recommended


<DCWC:Chart ID="Chart1" runat="server" RenderType="BinaryStreaming" >
<Series>
<DCWC:Series Name="Default_AutoRunWizard"></DCWC:Series>
</Series>
<ChartAreas>
<DCWC:ChartArea Name="Default"></DCWC:ChartArea>
</ChartAreas>
</DCWC:Chart>
