Build error object reference??

[Laura Carr]

I have been getting the following error fro an event in an
rpx.cs file. The error is as follows: An object reference
is required for the nonstatic field, method, or
property 'DataDynamics.ActiveReports.ActiveReport.Sections'
Can someone point me in the right direction in terms of
where I am going wrong.

private void Detail_Format(object sender, System.EventArgs
eArgs)
{
if(((CheckBox)Test.Sections["Detail"].Controls
["chcomplaint"]).DataField == "1")
{
((CheckBox)Test.Sections["Detail"].Controls
["chcomplaint"]).Checked = true;
}
else
{
((CheckBox)Test.Sections["Detail"].Controls
["chcomplaint"]).Checked = false;
}

}

It's not entirely clear - what's "Test" in this case?

Btw, your code could be made a lot cleaner by separating things out:

CheckBox cb =(CheckBox)Test.Sections["Detail"].Controls["chcomplaint"];

if (cb.DataField=="1")
{
cb.Checked = true;
}
else
{
cb.Checked = false;
}

The if/else block could then be changed to:

cb.Checked = (cb.DataField=="1");

Test is the name of the Report file (Test.rpx). I did
what you said and my code now looks like this below.
However I am now getting this build error: An object
reference is required for the nonstatic field, method, or
property 'DataDynamics.ActiveReports.ActiveReport.Sections'
Have you any Idelas what I've done wrong??

CheckBox cb = (CheckBox)Test.Sections["Detail"].Controls
["chcomplaint"];
if (cb.DataField == "1")
{
cb.Checked = true;
}
else
{
cb.Checked = false;
}

Ah. In that case, the problem is that you're trying to use an instance
property as if it were static. You'll need a reference to an instance
of the Test class.

Im sorry im really new to coding and im not 100% sure what
you mean here. How do I create a reference to an instance
of a Test class and where abouts should I do this. Thanks
so much for your help.

I don't know about reports, to be honest, which is a problem here -
chances are there's already an instance of Test somewhere, but without
knowing more about reports I can't really tell you how to find it.

I would *strongly* suggest that you start from scratch and learn "plain
C#" first, then start learning about reports when you're comfortable
with C# itself. That way you'll find a lot of the concepts a lot less
daunting, and will be able to solve problems like this easily.

Hi Laura,

While I have never worked with ActiveReports just with CR I assume they
follow the same way of building them. I tell you this cause the explanatio
below is based on CR no on ActiveReports.

CR create a class named like the report you create, if you create a report
named Report1 you will get two files:
Report1.rpt which contains the data needed by the designer and I assume the
report itself, and other named Report1.cs this is the code used in your
program, there you have a Report1 class that derived from Report which is
the abstract base class.

After all this explanation what I think is happening is that you are not
creating a new instance of the report, just using the name of the report
which is a type ( class )
You have to create an instance first:

Report test = new Report1();

Again, remember that the above is valid for CR but I can bet that it's what
you are seeing

Cheers,
