I am having a treeview and a set of graphs in a asp.net page. When I am trying to populate graphs on page load it is showing some free text along with the graphs, every thing is fine if I am generating on graphs on click of a button or treeview node.

Can anyone please help me on this...

The free Text is like this:
(function() {var fn = function() {$get("ctl00_scm1_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})(); WebForm_InitCallback();var ctl00_MainContent_TreeDashBoard_Data = new Object(); ctl00_MainContent_TreeDashBoard_Data.images = ctl00_MainContent_TreeDashBoard_ImageArray; ctl00_MainContent_TreeDashBoard_Data.collapseToolTip = "Collapse {0}"; ctl00_MainContent_TreeDashBoard_Data.expandToolTip = "Expand {0}"; ctl00_MainContent_TreeDashBoard_Data.expandState = theForm.elements['ctl00_MainContent_TreeDashBoard_ExpandState']; ctl00_MainContent_TreeDashBoard_Data.selectedNodeID = theForm.elements['ctl00_MainContent_TreeDashBoard_SelectedNode']; ctl00_MainContent_TreeDashBoard_Data.selectedClass = 'ctl00_MainContent_TreeDashBoard_4 '; ctl00_MainContent_TreeDashBoard_Data.selectedHyperLinkClass = ''; for (var i=0;i<6;i++) { var preLoad = new Image(); if (ctl00_MainContent_TreeDashBoard_ImageArray[i].length > 0) preLoad.src = ctl00_MainContent_TreeDashBoard_ImageArray[i]; } ctl00_MainContent_TreeDashBoard_Data.lastIndex = 21; ctl00_MainContent_TreeDashBoard_Data.populateLog = theForm.elements['ctl00_MainContent_TreeDashBoard_PopulateLog']; ctl00_MainContent_TreeDashBoard_Data.treeViewID = 'ctl00$MainContent$TreeDashBoard'; ctl00_MainContent_TreeDashBoard_Data.name = 'ctl00_MainContent_TreeDashBoard_Data'; Sys.WebForms.PageRequestManager.getInstance()._registerDisposeScript("ctl00_MainContent_up1", "ctl00_MainContent_TreeDashBoard_ImageArray.length = 0;\r\nctl00_MainContent_TreeDashBoard_Data = null;"); Sys.Application.initialize(); //]]>

Sriram,

There are some problems in the following code.

ScriptManager.RegisterStartupScript(TryCast(sender, Page), Me.[GetType](), "onload", [Where is start script tag here?] s & " </script><script language='JavaScript'> " & s2 & " </script><script language='JavaScript'> " & s3 & " </script><script language='JavaScript'> " & s4 & " </script><script language='JavaScript'> " & s5 & " </script><script language='JavaScript'> " & s6 & " </script>", True)

I didn't find start <script> tag. You have used so many <script> tags! Try the code below

ScriptManager.RegisterStartupScript(TryCast(sender, Page), Me.[GetType](), "onload", "<script language='JavaScript'> " & s & s2 & s3 & s4 & s5 & s6 & "</script>", True)

[Sriram]

Vivek,

I have added the start script tag but the problem still remained

Thanks,
Sriram

Sriram,

I would suggest you to refer the example present in our documentation here. This is the similar kind of example. Hope this will help you to find out the issue.

[Sriram]

Hi Vivek,

I have checked the example you have provided. The Problem is reflecting only if I am populating the graph on page load but not on generation of any event. Can you please provide an example which is generating a graph on pageload in asp.net.

Thanks

Please refer to the example below:

Hi Vivek,


Where do we need to write the following code if we are required to generate the graph on page load.

Can you please provide a solution file for the above example.

String xaml = GetXAML();
string s = "vChart.setDataXml(\'" + xaml + "\');"
+ "vChart.render(\"VisifireChart1\");";
ScriptManager scriptManager = ScriptManager.GetCurrent(Page);
ScriptManager.RegisterClientScriptBlock(sender as RadioButton, this.GetType(), "onClick", "<script language='JavaScript'> " + s + " </script>", false);

[vivek]

Sriram,

You have to write the same code as it is, in the Page_Load event handler. In the above example, it is written inside oncheckedchanged event of RadioButton. You can copy and paste the same .aspx and .cs code in your project and it will work.
