During runtime check if rptDoc holds a value. May be rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt")); returns null.

"Expression has been evaluated and has no value" is the value I am getting at rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt"));

But the report is available in proper place. What I have to do to solve this?

If the Reports folder is available in the application root then try
rptDoc.Load("~/Reports/STTCertificateAnnual1.rpt");

HTH!

What is the value you get when you try Server.MapPath("Reports/STTCertificateAnnual1.rpt") in the immediate window?

"Expression has been evaluated and has no value"

is the value I am getting at immediate window of rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt"));

Check the value of "rptDoc.IsLoaded" when using the original code rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt"));

It returns true.

I am getting the business objects' symbols(Export, print, Page nagivator, etc.) also at my page followed by my error.

In that case, I've lead you in the wrong direction. The report document is not the cause of the error. Sorry.

Check the parms collection for values. Also check if the no of params you are passing matches what the report is expecting.

Other than that, I've no clues to what is going wrong.

Actually, I pass 4 parameters only. If I pass the same into report directly, I can able to view the report. Through coding, I am trapped. However, you have spent your time for me. Thanks a lot.

Hello,

I am using Microsoft Visual Studio 2008. I am creating one website using ASP.net with C#.

I have taken one GridView control. In that I am adding 2 columns & bind them to the mysql database.
When mouse cursor moves to the records in the gridview then records turn in to hyperlink record. I do this thr' following code

e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline'";
e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";

My problem is i want when we click on the specific record/row then one columns that record should get display in TextBox & next columns selected record get display in DropDownList contrl.
So how can i achieve it?

Thanks in advance
Nikesh

I've not done this in VS 2008 / .NET 3.x. so some tinkering might be needed.

Check if you can associate a command name and a command event to the column, just try playing around with the item template. If you can then use it to raise the command event and invoke the edit mode for that row and take it from there.
