body onLoad not calling dynamicly made javascript function

Thanks for all your help so far I have made the following changes

This is the code on run:

<body>
<form method="post" action="ResultsDetails.aspx" id="form1">
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"    value="/wEPDwUJNzQ5NzY1NjU0ZGRuWExqnYyaWn0sRggTtOIdHlawc3aZvdNLKpOq0D+uMQ==" />
</div>

 <div id="placeholder" style="width:600px;height:300px;"></div>


<script type="text/javascript">
//<![CDATA[
var arrayOfResults = new Array(); 
 arrayOfResults[0] = 2; 
 arrayOfResults[1] = 4; 
arrayOfResults[2] = 5; 
arrayOfResults[3] = 1; 
arrayOfResults[4] = 4; 
 var numberArray = Array(1, 2, 3, 4, 5); 
  //]]>
</script>
</form>

<div id="codeGeneration">
  <script type="text/javascript">
   $(document).ready(function () {
      $.plot($('#placeholder'), [arrayOfResults, numberArray]); 
     });


</script>
</div>

</body>

The plot method is being run but i keep gettin the error saying that the arrays havent been initalised?

im using 

 ClientScript.RegisterStartupScript(this.GetType(), "run", sb.ToString() ,true);

to write the array code.

Sloved I did the following

  private void generateJScriptArray(int[] array)
{
    StringBuilder sb = new StringBuilder();        
    sb.Append("var arrayOfResults = Array(); \n ");

    for (int i = 0; i < array.Length; i++)
    {
        sb.Append("arrayOfResults[" + i + "] = " + array[i] + "; \n ");
    }

    sb.Append("var numberArray = Array(1, 2, 3, 4, 5); \n");

    sb.Append("alert(numberArray[0]); \n");

    sb.Append("$(document).ready(function () { \n  $.plot($('#placeholder'), [arrayOfResults, numberArray]); \n });");

    ClientScript.RegisterStartupScript(this.GetType(), "run", sb.ToString() ,true);
}

Thanks to all who helped.

You could try 

<body onload="javascript:run()">

Or seeing that you're loading jQuery, why don't you try executing the run function with jQuery's document ready event, instead of the body onload.

$(function(){
    run();
});

Take into account when initializing the numberArray array, it should be

var numberArray = [1, 2, 3, 4, 5];
//instead of
int [] numberArray = {1, 2, 3, 4, 5}; //It feels like C#

Also, remove the following

(function () { 
    $.plot($('#placeholder'), [arrayOfResults, numberArray]);
} //missing );

from your run function and leave only the plot line

$.plot($('#placeholder'), [arrayOfResults, numberArray]);

as the function run will be called when the page and all external scripts are loaded (either using onload or jQuery document ready)

Hope it helps,

you can also do it without using script manager..

string Code = "<script> alert('Foo Alert');</script>";
ClientScript.RegisterStartupScript(this.GetType(), "someKey", Code);

Use the ScriptManager to register the startup script. Something like this:

ScriptManager.RegisterStartupScript(this, this.GetType(),"somekey","your run script",true);
