well let me add more detail. what i am doing is reading a xml file into a datatable. I need to display those fields into the report but I cant seem to get it to work. In the textbox field under dataelementname i provided the column name but when the report displays it is blank. I have confirmed that the datatable has rows with data in them.

What have you done so far ?
Have you already defined the parameter in the report and pass it using LocalReport.SetParameters() method ?

Ok, then you have the report, the form with the reportviewer and that report defined for the reportviewer. What code are you using to assign the parameters and how are you showing in the report ?

right now I have a textbox field on the report. I want to show the passed parameter (orderNumer) on the textbox

Then you define the parameters and select the textbox. Right click and choose "Expression" and in the expression box you will find a Parameter category where you can choose the parameter you want.
Finally you just have to use this code:

Dim parameters(0) As ReportParameter
parameters(0) = New ReportParameter("ParameterName", "Value to be showed in the report")
frm.ReportViewer1.LocalReport.SetParameters(parameters)

Open in new window

I did the above steps with the below code. (I replaced and tried your sample)
    Dim report As LocalReport = New LocalReport()
        report.ReportPath = Application.StartupPath & "\Labels\Report2.rdlc"
        Dim parameters(3) As ReportParameter
        parameters(0) = New ReportParameter("Warehouse", "Jim")
        parameters(1) = New ReportParameter("CDate", "Jim")
        parameters(2) = New ReportParameter("OrderNum", "Jim")
        parameters(3) = New ReportParameter("Trans", "Jim")
        report.SetParameters(parameters)

Open in new window

Sorry I did not finish what I was typing, when the report prints all it shows is "Parameters!CDate.Value" w/o the quotes
Dim report As LocalReport = New LocalReport()
report.ReportPath = Application.StartupPath & "\Labels\Report2.rdlc"
Dim parameters(3) As ReportParameter
parameters(0) = New ReportParameter("Warehouse", "Jim")
parameters(1) = New ReportParameter("CDate", "Jim")
parameters(2) = New ReportParameter("OrderNum", "Jim")
parameters(3) = New ReportParameter("Trans", "Jim")
report.SetParameters(parameters)
Export(report)
m_currentPageIndex = 0
Print()

Open in new window

You're trying to print/export the report and does that shows ok for the other things ?

All I have is some textboxes that have statis text and that parameters. The static text shows fine.

jimseiwertAuthor Commented:
O have tried to open the report in the reportviewer without printing or exporting and it still displays the same with showing "Parameters!Trans.value

It almost seems as if it is thinking it is a string vs a parameter

jimseiwertAuthor Commented:
I got it, in the expression when I selected the parameter as the value it did not add a equal sign in front of it. Once I added that it worked. Thanks for your help

jimseiwertAuthor Commented:
Note to all others. In the expression don't forget the "=" in front of the parameter
