Hi Michael,

For DataSet "OnFetch" Event I am able to call data column value and placing that value in reportcontextParameter.
reportContext.setParameterValue("mylabel",dataSetRow["label"]);

In Report I m creating the One Static Element "Text":-
For this "OnCreate" Event I m retreiving the Value from ReportContextParameter and binding to the text property of component.

Here I am Attaching the datasource as well as report.Generally we can Drag.But I need this to build my requirement.
Could you please help me to retrieve the value in Java Script Event of Component.

Thanks and Regards
Swetha.

Rather that do this in the on create event, simply do it inside your text control. You can access dynamic values (like parameters) when defining a text control via the "<VALUE-OF>" tag. This tag will allow you to add a spot in the text control that will be substituted in at run-time with a dynamic value. 
 
To try it out, when in the Edit Text Item window, select "Dynamic Text" from the drop-down and then click on the VALUE-OF button.

I want to retrieve the value from dataset in java script Event and need to perform some external function on that value(Data Set Value)at the time of creaton of component.so Instead of VALUE-OF I need to access that value in Java script Event.

Could you please help me................

Swetha,

Here's a couple ways you can access your dataSet value in a text box. One way requires binding the text item to the dataSet, the other does not. Let me know if you have questions.
