Hi Chavdar,
Thanks for your response. the Link issue worked good :)
But for the RefreshReport() method I think it is needed for the
WebForms Report Viewer. i have a ReportViewer object in a webPage and I set its DataSource in the Page_Load Event. but when the page is first loaded I get this exception inside the ReportViewer object:
Missing opertator before _ID operand.
Description: An
unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the
error and where it originated in the code.
Exception Details: Telerik.Reporting.Data.ParserException: Missing opertator before _ID operand.
Source Error:
An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of
the exception can be identified using the exception stack trace below.

But after I press the Refresh button everything works fine. Here is the code inside the page:
| protected void Page_Load(object sender, EventArgs e) |
| { |
| if (!IsPostBack) |
| { |
| ReportViewer1.Report.DataSource = dal.GetEmployersPostingsJob(JobID); // This function Returns DataTable |
| ReportViewer1.DataBind(); |
| } |
| } |
I tried also to remove the ReportViewer1.DataBind(); line but still getting the error. That's why i think the report needs the Refresh function.
Also I have another question:
When I set
ShowNavigationGroup or
ShowRefreshButton Properties to true I got them twice in the report viewer toolbar!! when i set these properties to false i don't get them at all in the tool bar.
You can see what i mean in the following link:

How can i make them appear only once?
Please don't be annoyed with my long and many questions, that's my first time to use your reporting suite :).
Best regards,
